2) PLUMBING HOOK-UP
The heater is supplied with 3/8” brass compression fittings that are compatible with either copper or plastic
pipes. 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 trunk 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.
System Requirements:
Minimum/maximum working pressure: 30 PSI/150 PSI
Optimal operating pressure range: 35 to 80 PSI
Minimum turn on flow rate is model dependent (refer to the table below)

*Special suffixed models (i.e. CA, etc.), will have identical temperature rises as their base model
For optimum performance, Eemax recommends the use of isolation valves (full flow ball type) on the inlet and
outlet pipes.
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!
