SECTION V: WATER CONNECTIONS
WARNING
Failure to install and maintain a new, listed pressure relief valve will release the manufacturer from
any claim, which might result from excessive temperature and pressures.
Keep clear of the pressure relief valve discharge line outlet. The discharge may be hot enough to
cause scald injury. The water is under pressure and may splash.
WARNING
DO NOT reverse the inlet and outlet (cold and hot water) connections on the water heater. This may
cause a hazardous operating condition or the water heater may be inoperable
WATER QUALITY
The EVERHOT
® water heater must have the water quality within the following limits for long life and
reliable operation. The water supply should be tested to make sure the quality is within the specified
limits. If there is a problem with the water quality, contact your local water conditioning company for
equipment to condition the water supply to this appliance.
NOTICE
Operating this water heater with water conditions outside the specified limits will void the warranty.

Lime Condition Warning Signal:
If the EVERHOT
® water heater is operated under hard water conditions without a water conditioner, the
error code “LC” may flash on the remote temperature display. This code means the heat exchanger coil
is beginning to accumulate scale deposits and MUST be flushed (see Section X, “Flushing Procedure for
Lime Scale Removal…”). Contact your installer for a qualified service technician to flush the heat
exchanger. A water conditioner may be needed to prevent this condition from reoccurring.
NOTICE
Failure to flush the appliance when “LC” is flashing will cause damage to the heat exchanger. Damage
caused by lime or scale build up is not covered by the water heater warranty.
INSTRUCTIONS FOR CONNECTIONS
1. BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY
VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure
to prevent any water from leaking out of the pipes while making the water connections to the
water heater. The COLD water inlet and HOT water outlet are identified on the bottom casing of
the water heater. Make the proper plumbing connections between the water heater and the
plumbing system to the house. All soldering materials and piping must be compatible with
potable water. Unions should be installed on both the hot and cold water lines for future servicing
and disconnection of the water heater. Install a shut-off valve in the cold water supply line.
