3 - PLUMBING LINE CONNECTIONS:
Check the Following:
Main Water Supply Line, Drain Access, Electrical Outlet, and Clearances to comlepte the install.
Location of Tank:
Units can be installed, almost anywhere. Inside or outside. However, use your common sense. Valves
may be water resistant, not water proof. Protect any system from the elements. Review issues on water flow rates and
pressure, and environmental and water temperature ranges. The tank should have access to the supply water, provide
filtered water to the home, be located close to a clean working drain, have an electrical outlet available, and be connected
according to all local plumbing codes.
Water Temperature Range:
Feed water temperature not to exceed 110°F or be allowed to go below 40°F. Protect unit
from exceeding high temperatures and direct sunlight, and never allow unit, the drain line and any water to freeze.
Electrical:
An uninterrupted alternating current (A/C) supply is required. The system is ideally located within 4-6 feet of a
110 volt outlet to allow the unit to be plugged in. A 24 volt motor and transformer is available for longer electrical runs (use
10-2 regular lamp gauge wire). The 24 volt transformer must be located inside.
Existing Plumbing:
Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily
and clogged with lime and/or iron should be replaced. Problem with iron? Our separate iron filter unit should be installed
ahead of any other unit. Old galvinized or combinations of plumbing materials can cause water issues and conditions.
Drain Connection:
Nominal drain line and drain size on 1354-HF (non-iron) units should be a minimum of 1/2”. Any drain
line exceeding 20’ in length and/or expected to flow over 5’ above the height of the drain port requires an increase in drain line
size to 3/4”. Install, non-restrictive, check valve in drain line, if drain water is expected to flow over 5’ above the height of the
drain port. Never restrict the backwash drain water flow.Teflon tape is the only sealant to be used on the drain fitting.
Check Incoming Water Pressure and Flow Rates:
A minimum of 35 PSI and 12 GPM for 1354 units is required for
backwash valve to operate effectively. Water pressure not to exceed or to surge in excess of a maximum of 65 PSI for the
system. Unsure of pressure or it’s ability to surge? A pressure reducing valve (PRV), or limiting pressure to 65 PSI is
recommended for this and many other kitchen and bath products in your home. Automatic valve is rated for 100 PSI and the
tank is rated for 150 PSI, however the overall system with various connections has limitations to excessive pressure. Water
pressure measuring 65 PSI during the day may surge to over 100 PSI at night when the automatic backwash occurs.
Install (often required by code) a pressure regulator (PRV) if the water pressure exceeds or can surge above 65 PSI.
1 - PREPARE FOR INSTALLATION:
1) PLACE THE TANK WHERE YOU WANT TO INSTALL THE UNIT.
Make sure the tank is level and on a firm base. Black bases on tanks are glued-on and self-leveling. If necessary, lift tank
and tap the part of the base to floor, in order to level unit. Take note of the clearances necessary to complete the installation.
2) CHECK AND TIGHTEN VALVE HEAD ON THE TANK.
Hand Tighten the Valve Head in a Clockwise Direction. Make sure the stainless tank cover or plastic dome (1354 units) does
not interfere or cut into the connections.
WARNING: Stainless covers are non-functional, if “dinged” in handling, turn to good side.
2 - UNBOX UNIT: CHECK TANK AND VALVE AND LOCATE BYPASS AND MALE YOKE:
1) IDENTIFY THE MAIN WATER SUPPLY.
Do Not Assume. You may have to perform “the old bucket test” to determine where the water is coming from.
Make sure the whole facility is on the line. Some cold water lines (kitchen, island, wet bar sinks, refrigerators, ice
makers) may have been plumbed separately, if previously plumbed for (salt) softened water. You may have to recapture
those lines by replumbing that manifold. Or, capture the main water supply before the bypassed or “looped” away lines,
usually found at, or after, the main water shut off. However, some plumbing designs prevent this ideal installation. A sink
(point of use) filtration unit can be used for that missed location.
