❒
Inspect power cords, wires and electrical
connections.
Check for loose or frayed wires, burned contacts, and
signs of overheated wires. Check exterior power cords
to the main power source and from the electrical box to
the pump and heating elements. Check the ground wire
and thermocouple connections. Replace any wire that
appears damaged or has worn or cracked insulation.

Annually (every 12 months)

❒
Test and calibrate the unit’s control systems.
The chiller’s Test Mode checks the operation
of displays, control buttons, inputs and outputs. You
can also calibrate the supply and return thermocouples.

❒
Clean all surfaces that come in contact with water.
Minerals and other water contaminants cause heat-
transfer surface fouling and decrease performance,
especially in the water-cooled chiller’s condenser. Clean
all water-cooled condenser surfaces. The refrigerant side
does not foul because the refrigerant acts as a solvent
and operates in a closed filter cycle. See
WARNING: Improper servicing may
result in equipment damage or per-
sonal injury.
This equipment should be installed, adjusted,
and serviced by qualified technical personnel
who are familiar with the construction, opera-
tion and potential hazards of this type of equip-
ment.
All wiring, disconnects and fuses should be
installed by qualified electrical technicians in
accordance with electrical codes in your region.
Only certified refrigerant technicians should
recharge the refrigerant used in this system.
Always disconnect and lock out the incoming
