Casing / Panels
and Frames
Visual check for damage, rust
and dust accumulation.
For highly corrosive
environment, wash panels
quarterly with water and
neutral detergent solution. Wax
panels. Repair / re-paint where
required.
Insulation
Visual check for insulation
conditions.
Repair / replace insulation
material.
Fan
Visual check for run out of
balance and dust attached
Clean off dust as necessary to
negate possibility of fan running
out of balance
Motor
Ω
Visual check on wiring.
Insulation resistance check to
be carried out annually
Measure insulation resistance.
Should be more than 1MΩ.
Heat
Exchanger
Check for clogging by dust.
Check for leaks / damage.
Clean air inlet side as necessary.
Straighten any bent fins using
fins comb.
Condensate
Drain Line
Check for obstructions and
free flow of water
Clean to eliminate obstructions/
sludge and check condition of
drain
line. Pour water to ensure flow
Compressor
Ω
Check for high / low pressure.
Measure insulation resistance.
Check compressor for
abnormal noise/vibrations
Measure insulation resistance.
Should be more than 1MΩ.
Refrigeration
Operational
Readings
Make note of operational
reading in test cool/heat
Check operating pressures,
record super heat and
subcooling values
Safety
Devices
Check calibration of safety
devices such as HP and LP
controls, sensors, etc.
Check resistance of sensors,
pressure cut in / cut out of
pressure controls
Faults
Check for any previous fault
history on the unit.
Investigate any causes for
previous faults, reset fault
history.
Outdoor Fan
Speed Capacitor
Check for any bulge on the
capacitors and capacitance.
Make it electrically safe, prior
to measuring the capacitor’s
capacitance. Measured
capacitance should be within
the printed tolerances on the
capacitor.
