SECTION IV: 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 water heater.
NOTICE
Operating this water heater with water conditions outside the specified limits will void the warranty.

NOTICE
If the EverHot water heater is operated under hard water conditions without a water conditioner, the
diagnostic code “LC” may flash on the water heater’s control. This code means the heat exchanger coil
is beginning to accumulate mineral deposits and MUST be flushed (see Section IX, “Flushing Procedure
for Mineral 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 re-occurring.
CAUTION
Failure to flush the water heater when “LC” is flashing will cause damage to the heat exchanger.
Damage caused by mineral 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
