IX. MAINTENANCE

a. Disconnect power supply of the heater before any examination and repair.
The unit must always be powered off before opening the access panel. Always cut off the unit's
main power whenever the access panel is open or removed.
b. In winter seasons, please drain water clear of the machine, disconnect power
Supply to prevent any machine damage, and cover the machine body with plastic cover to avoid
dust. If the unit is stopped for a long period of time or for winterizing, the unit must be drained of
all its water. You will need to disconnect the IN and OUT water connections. Then the unit must be
tilted or blown out with air until all water is out.
c. Please clean this machine with household detergents or clean water, NEVER gasoline, thinners
or any similar fuel. The area around the unit should be dry, clean and well ventilated. Clean the
side heating exchanger regularly to maintain good heat exchange and conserve energy. Dirt
can accumulate on the evaporator. You can easily remove it by using a non-pressured water spray
without damaging the small aluminum fins. The cleaning of the plastic cabinet can be done with the
help of a brush and soap.
d. Check bolts, cables and connections regularly.
