Installation
(1) Water Pressure
A minimum of 20 pounds (1.4 bar) of water pressure is required for the regeneration valve to
operate effectively.
(2) Electrical Facilities
An uninterrupted alternating current (A/C) supply is required.
(3) Notes
• Water pressure should not exceed 125 psi (8.6 bar), water temperature should not exceed 110°F
(43°C), and the unit cannot be subjected to freezing conditions.
• Install the Central Whole House Water Filtration System after the supply lines to outside
faucets (unless outside faucets need to be free of iron).
• Install the Central Whole House Water Filtration System after any sediment filters or
neutralizing filters (ex: calcite, corosex), if applicable.
• The Central Whole House Water Filtration System should be installed before a water softener
or any taste/odor filters (if applicable).
• The drain line should be installed per local plumbing codes.
• Due to the air release during regeneration, the drain line must be secured at the end and
anchored throughout the run.
(4) Equipment Installation
Step 1. Place where you want to install the unit, ensuring the unit is level and on a firm base.
Step 2. During cold weather, the installer should warm the valve to room temperature before operating.
Step 3. All plumbing should be done per local plumbing codes. The residential drain line's pipe size
should be a minimum of 1/2 inch (13 mm). Backwash flow rates over 7 GPM (26.5 Lpm) or length
in excess of 20 feet (6 m) require a 3/4-inch (19 mm) drain line. Commercial drain lines should be
the same size as the drain line flow control.
Step 4. Lubricate the distributor o-ring seal and tank o-ring seal. Place the main control valve on the
tank. Only use silicone lubricant.
All keys will lock after 3 minutes during standby. Press and hold the “MENU” key for
3 seconds to unlock.
Step 5. Plumber tape is the only sealant to be used on the drain fitting.
Step 6. Place the bypass in the bypass position. Turn on the main water supply. Open a cold water tap
nearby and let run a few minutes or until the system is free from foreign material (usually solder)
that may have resulted from the installation. Once clean, close the water tap.
