To mount the pump...
1. First, Close the supply water valve to the water heater.
2. Drain the water from the hot water pipe by opening a hot water faucet in the house. Let the water run until it stops flowing. Then drain the remaining water from hot water heater spigot. Leave the faucet open until pump installation is complete.
3. Disconnect the water heater at the hot water discharge.
4. Install the pump onto the water heater discharge using the 3/4” female fitting and gasket supplied on the pump ensuring that the pump shaft is horizontal. The pump should be installed so that it is pumping away from the hot water heater, towards the house. Confirm the direction of pumping by observing the flow arrow on the side of the pump housing. Be sure that the pump is not touching the exhaust vent piping of a gas or oil fired water heater.
5. Connect the hot water line to the 3/4” NPT discharge of the pump. Use pipe dope or Teflon tape when connecting to a 3/4 female NPT connection.
6. Reopen the supply valve to the water heater and allow the water to run until all the air has been purged from the piping.
7. Close faucet inside the house.
8. Plug the timer into a 115 V outlet. Plug the power cable of the pump into the timer outlet. Be sure to route the power cord so that it does not touch the exhaust vent piping of a gas or oil fired water heater.
9. Using the timer, set the pump to operate around peak use times, such as 30 minutes before the first shower until 15 minutes after last shower. The timer is 24 hr, 3 position with 15 minute intervals.
To install the valve...
The valve should be located at a faucet with the greatest piping distance from the water heater. If your home has a branched hot water line, more than one valve may be necessary. Do not use teflon tape or pipe dope on the valve threads.
1. Close both the hot and cold water angle stop valves below the sink.
2. Disconnect the risers.
3. Connect the 1/2”X1/2” flex hoses to the ports on the valve marked “Hot Out” and “Cold Out”.
4. Connect the 1/2”X3/8” flex hoses to the ports on the valve marked “Hot In” and “Cold In”.
5. Connect the 1/2” hose fitting from the “Hot Out” port to the left side of the faucet.
6. Connect the 1/2” hose fitting from the “Cold Out” port to the right side of the faucet.
7. Connect the 3/8” hose fitting from the “Hot In” port to the left angle stop valve.
8. Connect the 3/8” hose fitting from the “Cold In” port to the right angle stop valve.
9. Open both hot and cold water angle stop valves. Valve may be mounted to the wall with supplied mounting screws if desired.
