Pump Mounting: For Indoor Use
Note: Do not energize pump
until properly installed
1. Close the supply water valve to the water
heater located, in most cases, above the hot
water heater on the cold water inlet to the
hot 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 remaining water from hot water
heater spigot. Leave the faucet open until
pump installation is complete. If water does
not stop flowing, check to make sure the
water to the hot water heater has been
completely shut off.
3. Disconnect the hot water heater at the hot water discharge. (see Picture #1)
4. Install 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 the pump 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 (chimney) of a gas or oil fired hot water heater. (See Picture #2)
5. Connect the hot water line to the 3/4”
NPT discharge of the pump. Use pipe
dope or Teflon tape to seal threads when
connecting to a 3/4 female NPT connection.
If a gasketed flexible copper water heater
connector is used pipe dope or Teflon tape is
not required
6. Reopen the supply valve to the hot water
heater and allow the water to run until all
the air has been purged from the piping.
7. Close faucet inside the house.
