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
