Pump Mounting: For Indoor Use Only
1. Close the supply water valve to the water heater
located, in most cases, above the 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 owing. Then drain remaining water
from hot water heater spigot. Leave the faucet in the
house open until pump installation is complete. If
water does not stop owing, 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 tting. The pump should be
installed so that the pump is pumping away from the
hot water heater, towards the house. Conrm the
direction of pumping by observing the ow arrow on
the side of the pump housing (See Picture #2). Be
sure that the pump is not touching the exhaust vent
piping (chimney) of a gas or oil red hot water heater.
5. Connect the hot water line to the 3/4" NPT
discharge of the pump. Use pipe dope or Teon tape
to seal threads when connecting to a 3/4 female
NPT connection. If a gasketed exible copper water
heater connector is used, pipe dope or Teon 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.
8. Plug the line cord of pump into a 115V outlet. Be sure to route the power cord so
that it does not touch the exhaust vent piping of a gas or oil red hot water heater.
9. Using the timer (see pg. 6), set the pump to operate around your peak use times.
(ie. 30 minutes before the rst shower until 15 minutes after last shower).
