SECTION 2: INSTALLATION
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Installation and use MUST comply with existing state or local plumbing codes.
• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.
Step 1
Refer to Typical Installation Sequence (Figure 1) for correct placement
of neutralizer in relationship to other water treatment devices. Installa-
tion location is critical because it may change the effectiveness of other
products.
Step 2
Shut off all water at main supply. On a private well system, turn off
power to pump and drain pressure tank. Make certain pressure is re-
lieved from complete system by opening nearest faucet to drain system.
Shut off fuel supply to hot water heater.
Step 3
Gently rock tank from side to side in order to make sure the gravel shipped inside the tank is spread across the bottom of the tank (APUN301
only). Gravel may have shifted during shipping and handling. Locate the bypass valve and connect to the head assembly. Assemble the con-
nection fi ttings and connect to the bypass valve. Tighten the connection nuts on both the bypass and connections fi ttings by hand only. Close
both the inlet and outlet valves on the bypass and leave in closed position until instructed otherwise.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Installation and use MUST comply with existing state or local plumbing codes.
• Mount system in such a position as to prevent it from being struck by other items used in the area of installation.
• Install on a fl at/level surface. It is also advisable to sweep the fl oor to eliminate objects that could pierce the media tank.
To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water fl ow should match arrow on control valve. The inlet and outlet of other water treatment
equipment products will vary depending on the control valve brand used.
Step 4
Refer to diagram (Figure 2) for recommended plumbing procedure. Cut main
supply line as required to fi t plumbing to the inlet and outlet of neutralizer. Use
thread tape on nipple threads, as most pipe thread pastes will cause deterio-
ration of plastic fi ttings. Hold nipples with wrench while attaching plumbing.
DO NOT OVERTIGHTEN. If a boiler drain (not supplied) is to be connected, be
sure to install it on the outlet side of the APUN Series Upfl ow Acid Neutralizer
System.
