4) Operation
Plot the three holes for the mounting screws onto the wall. Mount vertically on a flat
surface (i.e. board or walI) larger than the unit itself. Make sure heater is secure by
utilizing a stud or the provided wall anchors. Keep away from any potential splashing or
leaking water and strong magnetic fields.
Plumbing connections are ½" NPT, and both the inlet and outlet can be found at the
bottom of the unit. When installing your water connections make sure to use ½" NPT
fittings. Please use the provided gaskets to prevent leaks. When tightening fittings, use
a back-up wrench on inlet and outlet fittings (flat sides of fittings are located behind
front cover). The cold water inlet is on the right side it should be preceded by a high
pressure discharge valve and a shut off valve in that order. The hot water outlet is on the
left side and runs to your hot water source. NEVER USE PVC ON HOT WATER
OUTLET. Use instead CPVC or other high temperature rated materials. Run water
through the heater for a few minutes to purge all air from the system. Shut off flow at
faucet to pressurize system. At this point check for and fix any leaks. If no leaks are
present move to next step.
Power wires and ground come into the unit from the upper right hand side of the back
panel. Use 6 AWG for your ground wire, running from the "E" space in the terminal
block all the way to the ground bar of the breaker panel. Run one 6 AWG wire from
each of the "L1" and "L2" connection points of the terminal block to the double pull
50
amp breaker at your panel.
