Plumbing installation checklist
Heater is supplied with clean potable water
Plumbing orientation is correct – water connections on the bottom - inlet on the right,
outlet on the left
Ensure piping connections are not causing stress or torque on the inlet and outlet
fittings
No leaks at water connection or in plumbing network
Water pressure is between 40-90 PSI (min 35psi)
Long pipe runs, high flow rates and valves closing can cause pressure spikes (water
hammer) above 1000 PSI. Consult piping schematic to ensure arrestors and regulators
are properly sized and located.
(with power off) Open supply valves to water heater - run water through fixtures to
purge all air and debris in system. With water flowing, visually inspect the clear
element tubes between the inlet and outlet manifold to ensure no air bubbles are
present. (this may take several minutes)
Using a flashlight, visually inspect heating chamber for any signs of leakage
Ensure Water Heater will not freeze
Ensure all local plumbing codes are met
Plumbing installation correct and complete

(with power off) - Proper ground,(not neutral) is clean, and tight
(no water flowing, do not turn it on, close outlet water shut off valve if uncontrolled
environment-left hand side) Apply power - ensure voltage and phasing is according
to model rating
Disengage power after voltage and phasing is confirmed (open outlet shutoff valve if
closed during step 14)
