INSTALLATION INSTRUCTIONS
1. Turn off the power to your hot water tank at the circuit
breaker.
2. Close the valve on the cold water supply line to the hot
water tank. If you do not have a valve on the cold water
supply line close the main water valve to the house.
3. Attach a hose to the drain valve on the hot water tank and
run the hose to a drain or into a bucket.
4. Open the drain valve and allow the system to drain down.
Note: Opening the faucet at a sink may speed the draining
process.
5. After the system has drained down remove the drain valve
from the hot water tank.
6. Install the nipple and tee supplied in the AquaMotionHot
Two fitting kit into or onto the pipe or fitting you removed
the drain valve from. Apply pipe dope or Teflon tape to
the male threads prior to installing the nipple and tee.
7. Tighten the tee so the middle opening of the tee is facing
the dedicated return line.
8. Stick the
¾” NPT male tail piece supplied with fitting kit
through one of the union nuts and thread it into the tee
opening that is facing the return line using a
5/8” allen
wrench. Apply pipe dope or Teflon tape to the male
threads prior to installing the tail piece into the tee.
9. Allowing a 5-inch space for the circulator installed between
the fittings and install either PEX or sweat fitting depending
on the return line tubing through the remaining union nut.
Attach the tail piece to the return line.
10. Place one of the gaskets supplied in the kit between the
circulator discharge and the threaded fitting which is now
attached to the tee and thread the nut to the circulator.
Note: The discharge end of the circulator is the end the
arrows on the stainless casting point at. Place the other
gasket between the fitting on the return line and the circula-
tor inlet. Tighten both nuts.
11. Open the valve in the cold water supply line to the hot
water tank. Check for leaks at the fittings. If a leak occurs
retighten or refit the joint. Note: To allow trapped air to
escape open a hot water faucet and allow the water to
run until it is clear of bubbles.
12. Turn power on for the hot water tank at the circuit breaker
13. Your kit contains a circulator with a built in timer. Follow the
step by step directions on the timer instruction sheet to
program the timer to meet your hot water needs.
