MAINTENANCE
The Saber Packaged Air Conditioners are premium quality
machines with very low maintenance requirements. Compressors
used in Saber Packaged Units are of hermetic reciprocating
type and are charged with the correct amount of refrigerant and
lubricating oil. Unless there is a leak in the system, no topping up
is generally required. All bearings used in the fan shaft, fan motor
and evaporator fan motor are permanently lubricated for life.
Lubrication is therefore not a part of the periodic maintenance
schedule.
EVERY MONTH
Remove the filters and blow compressed air over them to •
get rid of loose dust. Visually inspect the filter conditions,
replace them with new ones of same sizes if required.
Saber Packaged Air Conditioners are provided with a •
specially designed drain pan, for proper maintenance check
and clean blockages at drain connections if any.
EVERY THREE MONTHS
In addition to the monthly maintenance above, check the belt
tension of evaporator fan. A correct tension is indicated when
the belt has a relaxation of approximately 10 mm to 13 mm when
pressed lightly with a finger.
EVERY SIX MONTHS
In addition to the maintenance done every three months :
The condenser coils should be cleaned by spraying • water
over it at low pressure or with a brush while ensuring that
the fins are not damaged.
Check all electrical connections and tighten them if • required.
Clean all accessible electrical panels of dirt and dust. • Before
cleaning the control panels, ENSURE that the electrical
power to the unit is switched off.
EVERY TWELVE MONTHS
In addition to the maintenance done every six months :
Use a proper cleaning cloth to clean fan blades and • motors.
Ensure that the unit is working properly by checking, • current,
voltages, pressures and temperatures.
Check the earthing or grounding of the unit. •
Check the exterior of the unit for any signs of • corrosion.
Even though it is highly unlikely, if any corrosion that is seen,
should be removed by proper sanding the surface. Repaint
the unit with proper touch up paint, available from York.
Check the unit for any unusual vibrations or noise, • locate the
cause and rectify it by changing mounts, base isolators etc.,
as required.
