V-Periodic Preventive
Maintenance
IMPORTANT
If equipment preventive maintenance
is not performed, this may result in
loss of performance and the equip-
ment warranty can even become void.
Preventive Maintenance
Check the liquid line sight glass.
Test against leakages and repair them, if
required.
If operational conditions and liquid
sight glass
indicate lack of gas,
measure the system superheat and
subcooling. Please refer to "System
Superheat" and "System Subcooling"
sections.
If operational conditions indicate
overcharge, slowly remove (to minimize
oil loss) refrigerant through the service
Schrader valve of the liquid line.
Inspect the system to detect
abnormal conditions. Use the log sheet
to
register
unit
conditions.
A
comprehensive log sheet is an invaluable
tool for technical support personnel.
Quarterly Maintenance
Perform all monthly maintenance
services.
Check
sheave and bearing
fastening
bolts.
Adjust
them,
if
necessary.
Clean the condenser more often,
according to the installation site.
Clean the evaporator more often,
according to the installation site.
Check and note down service
voltages and currents of fan and com-
pressor motors.
Test the safety controls.
Check and note down wet bulb
and dry bulb temperatures at evaporator
inlet and outlet.
Check suction and discharge
pressure using the manifold.
Measure and register the system
superheat.
Measure and register the system
subcooling.
Annual Maintenance
Perform
all
recommended
quarterly and monthly maintenance
services.
Ask a qualified technician to
verify the adjustment and operation of
each control, and also inspect and
replace contactors
or controls,
if
necessary.
Remove cabinet panels and
eliminate rust points.
Replace
defective
thermal
insulation and hardware.
Touch up internal and external
paintings, if required.
Eliminate oxidation.
Inspect the condenser pipes and
clean them, if required.
Inspect the expansion valve bulb
for cleaning. Clean it, if required. The
contact between the bulb and the
suction line must be excellent and
adequately isolated.
Measure the compressor motor
electric insulation.
IMPORTANT
Perform all inspections and mainte-
nance services at recommended
intervals. This will extend the equip-
ment life and reduce the possibility of
equipment failure.
Operational conditions of this unit shoulf
be logged monthly. The operational data
sheet may be an invaluable tool for
technical
support
personnel during
diagnosis.
By
noting
operational
condition trends, the operator can often
foresee and avoid problems before they
become serious. If the unit is not
operating properly, please refer to the
irregularity analysis section, at the end
of this manual.
Weekly Maintenance
After the equipment has been running for
approximately 30 minutes and the
system is stable, check the operation
conditions and follow these checking
procedures:
Clean permanent air filters more
often, according to the installation site.
Monthly Maintenance
Clean permanent
air
filters.
Replace throwaway filters.
Check fan belts for tension,
alignment and wear.
Clean the fan volutes.
Tight again all terminal bolts.
Clean the evaporator pan, the
hose and the condensed water drain.
