2) PLUMBING HOOK-UP
The heater is supplied with brass compression fittings that are compatible with either copper or plastic
pipe. “Single Point” has 3/8” fittings. Both “Flow Controlled” and “Thermostatic” units have ½” fittings.
Make sure these fittings are used for this installation. Contact your Eemax representative for further
information.
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.
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.
For optimum performance, we recommend the use of isolation valves (full flow ball type) on the inlet
and outlet pipes.
1) The heater’s cold water INLET is on the
“RIGHT” and the hot water OUTLET is on the
“LEFT”. 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.
