2) PLUMBING HOOK-UP
The heater is supplied with brass 3/8” compression fittings that are compatible with either stainless steel flex
hose, copper or plastic pipe. Make sure these fittings are used for this installation. Contact your Eemax
representative for further information.
Eemax strongly recommends that the heater be supplied directly from the main cold water line when possible.
This helps to avoid a potential water flow interruption to the heater which could lead to a failure of the heating
element.
Minimum working pressure of 30psi.
Maximum Operating System Pressure of – 150 psi.
Optimum Operating Pressure 35 - 80 PSI (Anything over 80 PSI must have pressure reducing regulator).
For optimum performance, we recommend the use of isolation valves (full flow ball type) on the inlet and outlet
pipes.
BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER,
MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.
NEVER SUBSTITUTE THREADED PIPE FITTINGS USING PIPE DOPE OR TEFLON TAPE AND
NEVER SOLDER ANY PIPE CONNECTIONS WHILE ATTACHED TO THIS HEATER BECAUSE
DAMAGE TO THE HEATER WILL RESULT. DOING THIS WILL VOID THE WARRANTY!
1.
The heater’s water INLET and OUTLET are labeled. Install
full flow ball valves to the inlet and outlet pipes and run
water through the inlet pipe into a bucket to purge it of any
debris. Close the inlet ball valve.
2.
Make sure the inlet filter screen is present in the inlet
fitting and the inlet and outlet pipes are correctly aligned
with the heater connections to minimize stress on the
heater.
