PLUMBING INSTALLATION INSTRUCTIONS
STEP 1:
Thoroughly flush and check that all water lines are free of debris. Tighten the proprietary 20” 4 mm
copper HOT WATER line that is connected to the dispenser to the OUTLET located on the
left
side of the heater
when facing HotMax. Use the supplied ferrule and nut.
STEP 2:
Connect the COLD WATER supply line to the 3/8” INLET fitting on the
right
side when facing HotMax.
Properly seal all compression fittings. Be careful to not overtighten.
DO NOT
use pipe dope or Teflon tape on any fittings connected to the unit.
DANGER
Usin
g a non-proprietary hot water outlet pipe could result in injury, expose the unit to leaks and
damage, or produce incorrect outlet water temperatures.
STEP 3:
After tightening both fittings at the water heater, open the dispenser and let water run through the
heater for at least 2 to 3 minutes. This process purges all the air from the water lines and MUST be performed
prior to turning on the power at the unit.
FAILURE TO FOLLOW THIS STEP CAN CAUSE PERMANENT DAMAGE
TO THE HEATING ELEMENTS.
If any maintenance is performed on the water heater or the plumbing system that
may introduce air into the plumbing pipes, it is important to turn the power off to the water heater and purge
the air out of the lines before allowing the unit to power up.
STEP 4:
Carefully inspect all connections, unions, and the pressure relief valve (if installed) for leaks.
STEP 5:
TURN OFF THE DISPENSER BEFORE PROCEEDING TO ELECTRICAL INSTALLATION
