Semi Commercial Reverse Osmosis Water Filter System

Technical Overview

I. Important Notes

For correct operation of this appliance, it is essential to observe the manufacturer's instructions. If this system is to be installed permanently as a POU (Point of Use) or POE (Point of Entry) system, installation must be carried out by a qualified plumber or authorized technician to comply with Australian Plumbing Codes. This system contains electrical and plumbing components; use caution. If leaking occurs, turn the power off immediately before conducting maintenance or repair.

This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use by a responsible person. Children should be supervised to ensure they do not play with the appliance.

⚠️ If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.

⚠️ Keep out of reach of children.

II. Before You Purchase/Open

The system requires specific working conditions to be met before installation. If these conditions are not met, the system may not be suitable for the application and may not function as specified.

These systems are designed for filtration of mains water for the removal of minerals, salts, and other impurities. The system may also be used on other sources such as bore water; however, you should inquire with the supplier before purchasing for any use other than mains water to ensure the system is correct for the application.

III. Space Requirements

The LSRO Systems are not IP rated and therefore are not suitable for external installation without adequate weatherproofing or cover from the elements, including but not limited to rain, moisture, and frost. The frame of the system includes mounting holes so the system can be mounted to a wall. It is recommended that the system be mounted if possible, rather than free-standing, as this will help support the weight of the system when full of water. If necessary, the system is able to also free stand.

System Dimensions:
Depth: 20cm
Width: 37 cm
Height: 45cm

If the system is to be enclosed in a cover, allow adequate ventilation around the pumps and power supplies to prevent overheating.

Installation Introduction

I. Site Preparation

When a suitable installation location is identified, you will need to determine if the system will be mounted to a wall or free-standing. The system should ideally have both the water supply (feed water) and storage/point of use within a 5m radius of the system to reduce negative effects on pressure/flow and performance. It is also recommended that the process water (filtered water) does not have to travel more than 2m elevation above the system. This will ensure minimal backpressure is applied to the pumps. Where possible, have the water running to a point lower than or at the level of the system for best results.

Ensure that adequate space is allowed for access to all parts of the system. If mounted to a wall, the fixings should be removable, which can aid maintenance.

II. Installation – Mounting

When mounting the system, position it to the desired location and mark out the mounting holes. NOTE: It can help to unscrew and remove the blue cannisters on the front of the unit to reduce weight and gain better access to the mounting points to mark them.

III. Installation – Free-Standing

The frame of the unit is suitable to support the system if it is not mounted to a wall. You will need a firm, stable base such as concrete for the system to sit on. Where possible, it is best to fix the system to the ground or an adjacent structure that is already secured. This prevents the system from tipping over and avoids putting pressure on any of the plumbing connections.

IV. Installing Connections – Quick Connect

If you encounter a push-fit fitting, firmly push the tubing into the opening until you feel a “click,” signifying that the tubing has passed through the internal O-ring and is seated correctly. If leaking occurs, it may be due to roughly cut tubing or the tubing not being pushed in far enough. To remove tubing from push-fit fittings, depress the floating collet, then pull the tubing out. The LSRO units are fitted with blue locking clips. These must be removed first to release the fitting. You will also need to remove them from the fitting if you are trying to re-install the tubing.

Diagram Description: A diagram illustrates a push-fit connector. Text indicates to 'Depress Collet' to release the 'Tubing Will Now Release'.

Filter Protection

These systems are supplied with an inline Pressure Limiting Valve (PLV) fitted to the inlet port. This valve limits incoming pressure to 50 psi (350 kPa). If your incoming pressure is below 350 kPa, you can remove the PLV as it may further reduce your incoming pressure.

The system does not come standard with inlet fittings; these should be supplied by the installer unless the purchaser included them in the original purchase.

It is recommended that an anti-water hammer device is installed in the house to dampen water hammer commonly caused by washing machines. It is best to install these devices at the point of hammer, such as on the cold-water line at the washing machine or dishwasher for residential applications, or for commercial applications, install near any electric solenoid valves.

Drain/Waste

Reverse Osmosis Systems produce wastewater due to the RO process. This water must be discarded in accordance with local government regulations. For applications where feed water quality is fair (mains water), the wastewater can be sent to sewage/septic. NOTE: For septic systems, consult the manufacturer to ensure the increased water discharge is within specification. In cases where feed water quality is good, the discharge water may be suitable for utility use and watering non-food plants. Check with the supplier before using discharge water. If the feed water is high in salt, the wastewater will be concentrated with higher salt levels and may not be suitable for discharge into sewage or septic.

If the wastewater is not suitable for conventional septic or sewage, dispose of it in a rubble pit or evaporation pit in compliance with local regulations. Wastewater should not be allowed to flow into the environment unless permitted by local authority.

Cartridge Installation

(a) Pre-Filters

Cartridges should be installed in the order: Pleated Before Spun, Spun Before Carbon, Highest Micron Before Lowest Micron. For example, a common filter set would be 5uM Polyspun, 20uM Low Pressure Carbon, 0.5uM Chloramine Reduction Carbon. Install them in that order. Invoices usually list filters in the order of installation.

Cartridges must have their outer plastic shrink wrapping removed before installation. Maintain minimal contact with the surface of the carbon filter; handle by the end caps only to avoid contamination, as carbon absorbs smells and oils from the skin.

Gently lower the cartridge into the blue sump and locate the filter so the stem in the bottom of the sump inserts into the center hole of the cartridge. Do not drop the filter in, as this can break the plastic caps. Once the filter is located, screw the sump into the cap vertically. Wobbling the sump can help the filter locate into the guide lugs in the top of the cap.

The caps should screw up smoothly with little resistance; hand-tightening is usually sufficient. If you encounter resistance before the housing is more than ¼ tightened, the cartridge may not be aligned with the guide lugs. Remove the sump, align correctly, and then tighten. An opening spanner, if provided, is only required if hand-tightening is difficult or if slight leaking occurs. Do not overtighten housings, as this can cause long-term damage to the cap thread. The spanner can also help unscrew housings that become difficult to remove over time.

(b) RO Membrane

*** THE RO MEMBRANE DOES NOT COME PRE-INSTALLED. MANUALLY INSTALL BEFORE USE ***

1. Disconnect the tubing from the screw cap end of the membrane housing. Check the O-ring for good condition. If the O-ring is stuck in the cap, remove it and install it on the housing.
2. Unwrap the Reverse Osmosis Membrane and install it into the membrane housing. Handle the membrane only by the end stems. Insert the membrane into the housing with the O-rings first, so the stem without the O-rings is visible. Replace the membrane cap firmly but do not overtighten.

(c) Post Filters

The system is supplied standard with an inline 2.5" GAC filter. DI or Remineralising cartridges are also available, with the same installation principle. These filters are generally pre-installed. When replacing them, disconnect the tubing from each end, remove the fittings from the old filter, attach them to the new cartridge, and re-install. If the system was purchased with a DI filter, this GAC filter is removed, leaving an open end of tubing at the system outlet.

(d) De Ionising Post Filters

For DI Cannister filters: Temporarily run a small length of tubing from the system's outlet to flush water from the system before installing the DI system. This prevents TDS contamination from affecting the DI filter media. Flush until TDS shows a >90% reduction compared to the raw inlet water (minimum 30 minutes). After flushing, connect the ¼” tubing to the DI filter and run a tube to your tank/container or float valve.

Connecting the System

I. Tubing

Measure a length of tubing (Blue 3/8”) from the feed water connection to the system. Cut the tubing using poly cutters or a sharp box cutter, ensuring a clean, straight cut with no rough edges.

Measure a length of ¼” tubing from the drain valve (marked 'to drain' or 'Flow 1000') to a suitable drainage point.

Measure a length of ¼” tubing from the system's outlet point to your intended usage point or storage.

II. Power

The system is supplied with a 3-pin AU plug. Install this into a GPO (10A minimum). It is advised to also install a surge protector to protect the electrical components in case of a power surge or blackout. NOTE: If there is any damage to the cord, DO NOT install – contact the manufacturer immediately.

Start Up & Operation

I. Commissioning

NOTE: New filtration systems require a pre-flush before use. The GT1-20LS system will need to run for at least 15-20 minutes before first use to clear any residue or fines from the filters.

• Use a TDS meter to monitor the water and determine when the system is suitable for the intended application.
• When the system is connected correctly, turn on the incoming water supply and allow the first filter cartridge to fill with water. Once stabilized, turn on the power to the system.
• Turning on the power actuates the inlet solenoid valve, and water begins to pass through the remaining 2 pre-filters, then to the membranes. The pumps will turn on at this point.
• Once water reaches the membranes, the drain line should begin to sputter and produce water. It is normal for this water to be cloudy and discolored on first use.
• The water will then slowly pass through the membranes and post filter. The system will need to run for several minutes until water begins to flow from the outlet.

Your water is now suitable for use.

II. General Operation

The rating of this Reverse Osmosis system is 200GPD (Gallons Per Day) as per the membrane specifications, meaning this system is capable of approximately 0.5L/Min of water production. This will vary depending on water quality and other factors. The systems are designed to run in a closed-loop configuration where the system runs off a float switch or timer. This configuration allows for system downtime and helps extend the pump's lifespan as the system intermittently produces water.

When the system is installed in an open-loop configuration and the pumps haven't been allowed any downtime, you may expect a decrease in pump lifespan. If you intend to use the system this way, please contact FSA for a potential solution for your specific circumstance.

Production scenario for closed-loop configuration: The system runs for up to 8 hours a day with a 30-minute cool-down period. In this configuration, the system will produce approximately 250L +/- per day. This is the recommended runtime scenario for extended pump lifespan.

Production scenario for open-loop configuration: The system runs continuously without a cool-down period. In this configuration, the system will produce approximately 750L +/- per day. This is the maximum capacity, but it may also decrease pump lifespan.

*Note: Pumps come with a 90-day replacement guarantee/12-month pro-rata warranty from the date of invoice. If a pump fails within the first 90 days, it will be replaced. If it fails between 90-365 days, it will be covered on a pro-rata basis. Pumps and filters are considered consumable items.

III. Automation

The system is fitted with high and low-pressure switches. These allow the system to shut off when the tank is full or when the feed water has been shut off.

When power and water are connected and the outlet is open, the system will automatically produce water. When the outlet shuts off, the high-pressure switch will trip after a period (similar to a household pump), and the system will shut down. When the outlet is opened and pressure falls below the limit, the system will start up again.

Similarly, if the feed water is cut off, the low-pressure switch will trip, and the system will shut off after a few seconds.

If installing this system to a float switch in a tank, disconnect the high-pressure switch and connect the float valve terminals in its place. This will run the shut-off based on the float level rather than pressure.

TIP: If the system needs to be shut down for servicing, shut off the inlet water supply and allow pressure to bleed out (a few seconds) before shutting off the power. This makes disconnecting fittings much easier.

Maintenance

I. Replacement Parts

A list of replacement parts and their corresponding recommended lifespan for replacement is provided below.

II. Replacement Cartridges

On municipal water supplies, pre-filters should be changed every 45,000L (720 Hours constant run time) OR 6 Months, whichever occurs first.

Post Carbon Filter: This filter should be changed every 5,000L or 6 Months, whichever occurs first.

DI Resin: Due to resin nature and water quality variance, this media needs monitoring with a TDS pen or meter. DI resin extracts residual ions, reducing RO water to 0 TDS. The media requires changing once TDS exceeds your required limit. To change DI media:

• Inline DI Filter: Disconnect tubing from the inline filter and remove it from its mounting clamps. Unscrew the end cap in an upright position and remove the sediment pad and O-ring to avoid debris on the O-ring seal. Discard the filter media and rinse the cartridge with clean water, removing any remaining DI resin. Refill the housing with resin, replace the pad and O-ring, and replace the head cap.
• DI Cannister Filter: Undo the housing cap and remove the DI cartridge. Unscrew the filter from the bottom and discard the DI media. Rinse the housing and sediment pad with clean water, removing any expired DI. Fill the cannister with 1Kg of DI media (try not to compress it; gently tap to settle). Replace the sediment pad and screw the cap back on.
