WATER SUPPLY CONNECTION
□
Important: Do not install this water heater with iron or galvanized piping.
□
The water ttings on the Eternal water heater are 3/4" NPT.
□
When installing more than one unit to supply higher volumes of hot water in residential applications, the number
of Eternal water heaters required and the header pipe sizing needs to be properly sized to meet the total hot
water demand.
□
All pipes, pipe ttings, valves and other components including solder, must be approved for use in potable water systems.
□
The use of unions and manual shut off valves on both the cold water inlet and hot water outlet are recommended.
□
The use of brass, stainless steel or copper unions/nipples are recommended for Eternal water heaters.
□
Taking measures to prevent water pipes from freezing are important. In the event of frozen water pipes, Eternal
will not be able to activate its freeze protection function due to loss of water pressure and will be susceptible to
freeze causing serious unit damage.
!
□
The use of galvanized or dielectric unions are prohibited for use with an Eternal water heater. Failure to comply with
this warning will void warranty.
!
□
Be careful not to reverse the hot water outlet and cold water supply line connections to the water heater. This will cause
your water heater to operate improperly and void warranty. Make sure the hot and cold lines are connected properly.
FILLING THE WATER
□
Close the water heater drain valve by turning the knob to the right. The drain valve is on the lower right side of
the water heater. Refer to the gure below.
□
Open the cold water supply valve to the water heater.
□
To ensure complete lling of the tank, allow air to purge by opening the nearest hot water faucet. Allow water to
run until a constant, smooth ow is obtained.
□
Check all new water piping for leaks. Repair as needed.
!
□
Never use this water heater unless it is completely lled with water.
□
Be certain there are no loose particles or dirt in the piping. Keep a copper pipe diameter at NPT 3/4 inch
diameter to allow full ow. If the hot and cold connections are reversed, the heater will not work properly . Be
sure to connect them correctly.
□
If water ow is low, check the lter by removing the draining valve.
DRAINING THE WATER
□
Close water supply shut-off valve to the unit rst.
□
Connect garden hose to the draining valve located on the lower left side of the unit.
□
Open the valve by using a at head screwdriver to drain water with the hose.
□
After draining the tank, turn the valve body counterclockwise by hand to remove the draining valve from the unit
and clean the lter.
!
Do not open the drain valve without connecting a hose so that water can be diverted to an area where water
damage is not a problem. Do not remove the draining valve from the unit without rst draining the tank.
