Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your APEC WH-SOFTENER-30-FG Reverse Osmosis System and Water Softener bundle. This combined system is designed to provide both purified drinking water and softened water for your entire home, enhancing water quality and protecting plumbing and appliances from scale buildup.
Product Overview
The APEC WH-SOFTENER-30-FG bundle integrates two essential water treatment technologies: the ROES-PH75 Reverse Osmosis (RO) system and a 30,000-grain water softener. The ROES-PH75 system effectively removes up to 99% of various impurities from drinking water, including fluoride, chlorine, VOCs, PFAs, lead, arsenic, and mercury. It also includes a pH filter to reintroduce beneficial minerals and alkalinity. The water softener treats hard water throughout your home, preventing scale accumulation and corrosion, and features a microprocessor digital control valve for efficient operation.
Key Features
- Dual System Integration: Combines a high-performance Reverse Osmosis system (ROES-PH75) with a 30,000-grain water softener.
- Superior Drinking Water: ROES-PH75 removes 99% of harmful impurities and adds beneficial alkaline minerals. WQA Gold Seal certified.
- Whole-Home Soft Water: Delivers 100% soft, scale-free water, improving skin and hair quality and protecting appliances. Recommended for 1-3 bathrooms.
- Enhanced Efficiency: Reduces detergent and soap usage by up to 50% for laundry and prevents water spots on surfaces.
- Digital Control Valve: Microprocessor-controlled valve monitors water usage and optimizes regeneration cycles for minimal water and salt consumption.
- Durable Construction: Assembled in the USA with premium components for reliability and longevity.

Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your APEC water treatment system. Due to the complexity of plumbing and electrical connections, professional installation by a qualified plumber is highly recommended. Always consult local plumbing codes and regulations before beginning installation.
General Installation Steps (Consult Full Manual for Details):
- Site Selection: Choose a suitable location for both the RO system (typically under a kitchen sink) and the water softener (usually near the main water inlet, in a garage, basement, or utility room). Ensure adequate space for maintenance and salt replenishment.
- Main Water Shut-off: Turn off the main water supply to your home before starting any plumbing work.
- Water Softener Installation: Install the water softener unit and salt tank according to the detailed diagrams and instructions in the full owner's manual. This typically involves connecting to the main water line, a drain, and an electrical outlet.
- RO System Installation: Install the ROES-PH75 system, including the filters, membrane, storage tank, and dedicated faucet, following the specific instructions provided for the RO unit.
- Leak Check: After all connections are made and the water supply is restored, carefully check for any leaks.
- System Start-up: Follow the initial start-up procedures for both the water softener (programming the digital control valve) and the RO system (flushing new filters).

Operating Instructions
Water Softener Operation
The water softener operates automatically once programmed. The digital control valve monitors water usage and initiates regeneration cycles as needed. Refer to your full owner's manual for detailed programming instructions for the digital control valve. Key operational aspects include:
- Initial Programming: Set the time of day, water hardness, and regeneration time during initial setup.
- Automatic Regeneration: The system will automatically regenerate based on water usage or a set schedule, typically during off-peak hours.
- Salt Level Monitoring: Regularly check the salt level in the brine tank and replenish as needed to ensure continuous soft water supply.
Reverse Osmosis System Operation
The ROES-PH75 system provides purified water on demand through its dedicated faucet. Water flows through multiple stages of filtration, including sediment, carbon, RO membrane, and post-carbon/pH filters, before being stored in the pressure tank. Simply open the RO faucet to dispense purified water.
Maintenance
Regular maintenance ensures the continued efficiency and performance of your APEC water treatment system.
Water Softener Maintenance
- Salt Replenishment: Check the salt level in the brine tank monthly. Keep the tank at least one-quarter full, but no more than two-thirds full, with high-quality water softener salt pellets or crystals.
- Brine Tank Cleaning: Periodically clean the brine tank (every few years or as needed) to remove any sludge or insoluble materials.
- Control Valve Inspection: Ensure the digital control valve display is functioning correctly and that regeneration cycles are occurring as programmed.
Reverse Osmosis System Maintenance
- Pre-filter Replacement: Replace the sediment and carbon pre-filters (Stages 1-3) every 6-12 months, depending on water quality and usage.
- RO Membrane Replacement: Replace the RO membrane (Stage 4) every 2-5 years, depending on water quality and usage.
- Post-filter Replacement: Replace the post-carbon and pH filters (Stages 5-6) every 2-3 years.
- Sanitization: Sanitize the RO system annually during filter changes to prevent bacterial growth.
Troubleshooting
This section addresses common issues you might encounter. For detailed troubleshooting steps, refer to the comprehensive owner's manual or contact APEC Water Systems customer support.
Common Water Softener Issues:
- Water is not soft: Check salt level in brine tank, ensure control valve is programmed correctly, verify regeneration cycles are occurring.
- Excessive salt usage: Review control valve programming for regeneration frequency and salt dose settings.
- Water pressure drop: Check for clogged filters (if a pre-filter is installed before the softener) or issues with the control valve.
Common RO System Issues:
- No water from RO faucet: Check water supply, ensure tank valve is open, verify system pressure, check for clogged filters or membrane.
- Slow water production: May indicate clogged filters, a depleted RO membrane, or low incoming water pressure.
- Poor water taste/odor: Replace post-carbon filter, check for expired filters, or sanitize the system.
- Leaking: Immediately shut off water supply to the system. Inspect all connections and O-rings.
