Hot water tubing, pure water tubing, and drain water tubing are shown connected to the system unit and the drainpipe.

Installation Tips

1. How to Use the Quick-Connect Fittings

To connect tubing: Ensure the tubing is pushed into the fitting until it reaches the existing mark (approximately 0.8 inches). Secure the connection by placing the blue lock clip onto the fitting. This locks the tubing in place and prevents it from falling off.

Diagram Description: Figure 1 shows a fitting with a mark for full insert (✔️) and a cross (❌) indicating an incomplete insertion.

NOTE: If the tubing is not fully inserted, a seal will not be created, leading to leakage.

If the tubing is too long, cut it to a suitable length with a sharp utility knife or scissors. Cut the tubing squarely and cleanly.

Diagram Description: Figure 2 shows a diagram illustrating how to cut tubing cleanly and squarely.

2. How to Drill a Hole into Your Sink or Countertop (Optional)

Confirm if an existing hole is available for the RO faucet. If not, drill a hole following these steps. It is recommended to watch a YouTube video for guidance. Wear safety glasses.

• Choose a suitable place for the faucet, ensuring enough space around it.
• Use a diamond core bit for granite or a carbide drill bit for stainless steel. Do not use a hammer drill on natural stone, glass, or ceramic.
• Glue the provided sticker onto the sink or countertop and drill a hole the size of the sticker (1 inch).
• For stainless-steel sinks, make an indent with a center punch before drilling to guide the bit.
• Be careful when drilling porcelain sinks to avoid chipping. Apply firm downward pressure until the surface is broken through.
• Start drilling at the lowest speed, holding the drill straight. Apply firm pressure to prevent the bit from walking.
• Once through the surface, swirl the drill slightly to apply pressure in a circle.

Diagram Description: Figure 4 illustrates drilling a hole in a sink edge.

General Installation Precautions:

• Before installation, remove the system from the box and choose an easy-to-access, flat area under the sink. Do not lay the system on its side, back, or upside down.
• Ensure a power outlet is available in the cabinet or on the wall adjacent to the undercounter space.

WARNING: The system plug must be inserted into a grounding socket that complies with local codes and regulations. Ensure the system does not share the same power outlet as the garbage disposal.

• The system must be connected to the COLD water supply ONLY.
• Do not install the system where it will be exposed to direct sunlight, harmful chemicals, or places where it may be damaged.
• Do not install the system near any heat source or outdoors.

When the system fails, fault codes are displayed on the system and faucet screens.

NOTE: If errors persist after checking, contact customer service at +1-888-352-3558 (U.S.) or service@waterdropfilter.com.

Troubleshooting

a. After the system is plugged in, it cannot be powered on.

• Check if the power under the sink is off.
• Ensure the power plug is correctly inserted into the power outlet.
• Try plugging the system into a different power outlet to test.
• Contact customer service if the system still cannot be powered on.

b. No water comes out of the faucet or the faucet discharges water slowly.

• Check if the filter has expired and needs replacement.
• Ensure water inlet pressure is adequate (14.5-87 psi).
• Verify the water supply is on. Turn on the feed water adapter or water supply valve if necessary.
• Check for crimped tubing and remove any crimps.
• Confirm all pipes are connected correctly and fastened, and check for leaks at tubing joints.
• Ensure the water temperature is within the system's operating range (5-38 °C).
• If using well water, contact customer service for a specific solution.

c. High TDS of filtered water.

The system offers 90%+ TDS rejection after full flushing. If TDS is high:

• If the system hasn't been used for a long time, run the RO faucet for a while to normalize TDS readings.
• Replace the filter if it has expired.
• Check if the waste water pipe is crimped or clogged; remove crimps and re-align the drain saddle/pipe.
• If the source water has very high TDS, the rejection rate may be lower. Contact customer service for advice.

d. Filtered water from the RO faucet tastes like tap water.

• Ensure incorrect tubing installation is not the cause (e.g., waste water tubing connected to faucet).
• Replace the filter if it has expired, as indicated by the filter life indicator.

e. Water is not hot when taking hot water.

• Confirm the system is in heating mode.
• Verify the heating temperature has been set correctly (40-95°F range).
• Allow time for heating; the system heats to the set temperature gradually.
• The system can dispense a limited amount of hot water continuously before needing to reheat. Monitor outlet temperature via the faucet screen.
• If the above reasons do not apply, the heating module may be damaged. Stop using the system and contact customer service.

f. Hear the heating sound of the system every once in a while.

The system automatically heats water if the heating tank temperature drops below 4°C/7.2°F of the set temperature. You can disable the heating indicator if hot water is not needed.

g. The outlet water temperature is inconsistent with the temperature displayed on the screen.

• Initial cold water in the tubing may affect readings.
• There might be a deviation between the displayed and measured temperature due to heat loss into your cup. Use a thermometer at the faucet outlet for accurate measurement.
• The temperature sensor may have an error, causing display deviation.

h. The maximum temperature of the system is set below 203°F/ 95°C.

The system automatically determines the local boiling point. If it's below 95°C/203°F, the system reduces the maximum heating temperature by 5°C/9°F to prevent boiling and scalding.

i. Loud sound of RO system.

The sound should not exceed 65 dB. If it's loud:

• Ensure the system is placed on a flat, stable surface without shaking.
• Do not place the system against the cabinet, as vibration may occur.
• Check water pressure; it should be between 14.5 psi and 87 psi. Sound decreases when pressure stabilizes.

j. The heating switch cannot be turned on.

• Check if the system is in the initial flushing status or if the filter was just replaced. Heating is disabled during these times.
• Check for error codes on the system and faucet display. Internal system errors can prevent heating. Consult fault codes for causes. Contact customer service if issues persist.

System Maintenance

If the system is not used for a long time:

• Turn off the water inlet valve.
• Disconnect the system's power supply.
• Remove the filter, seal it, and store it in the refrigerator (not freezer) at temperatures above 0°C (32°F) to prevent freezing and cracking of the heating tank.

When using the system again:

• Turn on the cold water first and run the system for 10 minutes to flush filters.
• Then turn on the hot water and run it for 5 minutes to discharge water from the heating tank, preventing bacterial growth.

Replace filters regularly according to the filter life indicator.

NOTE: Filter performance is tested in a lab but actual service may vary. Replace filters promptly if blocked.

• Clean the system with clear water only. Do not spray water directly. Avoid steel wool, abrasive cleaners, or corrosive liquids.
• If feed water contains large particles or high hardness, install a pretreatment device before the system.
• Do not use the system if the sewage tubing is clogged to prevent leaks.
• Regularly check for water leakage in the system and tubing fittings to prevent property damage.
• Regularly check the power supply and line for damage to avoid accidents caused by electric leakage.
• Use only company-provided accessories. The company is not responsible for issues caused by third-party accessories.
