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


Visual check on wiring.
Insulation resistance check to
be carried out annually
Measure insulation resistance.
Should be more than 1M.
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


Check for high / low pressure.
Measure insulation resistance.
Check compressor for
abnormal noise/vibrations
Measure insulation resistance.
Should be more than 1M.
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.
