Water connections

WARNING:
▶ Do not apply heat or solder to
connections or pipe if they are already
connected to the unit.
WARNING:
▶ Do not install a check valve within 10
feet of the inlet.
NOTICE: Disclaimer
▶ In the Commonwealth of Massachusetts
a pressure relief valve shall be installed
on the cold water side by a licensed
plumber. (MGL 142 Section 19,
Approval number P1-09-25).
▶ Do not use plastic (PEX or CPVC) piping within 3 feet on
either side of heater.
▶ The heater must be connected directly to the main cold
water supply and not to pre-heated water. (The inlet
water temperature must not be greater than 86 °F).
▶ It is highly recommended to install shutoff valves on both
the inlet and outlet connections of heater.
▶ For servicing it is recommended that you use ¾ inch or
½ inch copper or high-pressure flex connections.
▶ Use Teflon tape for sealing pipe threads. Do NOT use pipe
dope.
▶ Remember to keep the hot water pipe runs as short as
possible.
After the heater has been plumbed, and before you wire it,
flush it with water to remove any debris or loose particles.
Heater must be full of water and air purged before power is
turned on. Failure to do so may result in damage to the
product that is not covered by warranty.
▶ After flushing and filling the heater with water, (with power
off) disconnect the inlet connection and inspect the filter
screen for any debris that may have been flushed through
the system.
The inlet and outlet connections are clearly
marked on the heater. They each have a
¾ inch NPT connector.
▶ Check the pressure of the main water supply. To operate
correctly, the heater needs the operating pressure >14.5
PSI (1.0 Bar).
