• When connecting to a plumbing system that utilizes Flex or PVC, a
T&P
relief valve
should be used as added safety.
•
Do not connect the unit directly to CPVC pipe. You must use at least three feet of
copper pipe prior to connecting to any CPVC connection.
• WARNING:
Do not solder any pipes with the unit connected to the pipes. Doing so
will damage the flow meter and void your warranty.
•
Before energizing the heater, run water for a minimum of three (3) minutes and
verify that all air has been removed.
•
Installation of an air separator device is recommended for installations where air can
be easily introduced into the water system (i.e. Well water systems, lake pumps, and
other municipal systems).
•
A shut off valve MUST be installed on inlet side of unit. A shut off valve on the
outlet is recommended.
Pipe Preparation:
• Cut the tube so that the ends are square. WARNING: Ensure that there are no burrs or
damage to the
cut end. This will prevent any damage to the internal o-ring.
• Once the tubing end is cut square and clean, mark the pipe to be installed at a distance
of 1 ¾” from the end of the pipe. This is the insertion depth.
• Check that fittings and tubing are
clean, in good condition and are free from damage
and foreign objects.
Flushing the Line:
•
Before connecting the copper pipe to the water heater, it is extremely important to
flush the lines to eliminate all plumbing paste, residue, or debris in the lines.
Installation to Quick-Connect Fitting:
• If using PEX tubing, insert the supplied stiffener into the end of the pipe.
•
To assemble correctly, the tubing needs to be pushed into the fitting until it reaches
the mark previously scribed. Push the tube firmly with a slight twisting action until it
reaches the tube stop.
• Connect the cold water line to the water heater inlet marked cold water. Connect the
hot water line to the water heater outlet marked hot water.
•
After inserting both fittings, open the hot water faucet and allow water to run
through the water heater for at least three (3) minutes, cycling the flow on and off
every minute. This process clears all the air from the lines and must be performed
prior to turning on the power at the unit.
WARNING:
Failure to do this may
damage the flow meter or heating elements and will void your warranty.
