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.

prevent any machine damage, and cover the machine body with plastic cover to avoid dust.

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.

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.
