Maintenance/Repair Introduction
By nature, heating, ventilation and air conditioning equipment deteriorates with normal use. To
help alleviate this, preventive maintenance is required. When properly maintained, the systems
will experience improved efficiency and increased equipment life.
Failure to perform preventive maintenance of The Whalen Company equipment, by a licensed
HVAC technician per the recommended schedule, will result in loss of factory warranty. Logs
are provided in this manual and are to be filled out documenting all repairs and maintenance
performed.
Preventive Maintenance
General (Annually)
o
Visual Inspection for corrosion and proper mounting, alignment and sealing
Installation of unit
Air Connections
Water connections
Condensate drainage pitch
o
Functional Inspection of operation
Heating mode
Cooling mode
Amperage draw
Supply voltage
Coils (Annually)
o
Clean the coils by removing the blower panel and brushing the fins with a stiff, plastic
bristle brush, taking care not to bend or damage the fin surface. After brushing, the
coil should be vacuumed to remove loose dirt.
o
Check insulation for proper coverage to maintain efficiency and prevent sweating.
o
Piping – inspect all connections for leaks and corrosion.
o
Valves – Check for proper operation, corrosion and leaking.
Motor (Annually)
o
If there are no oil tubes present, the motor is permanently lubricated.
o
If oil tubes are provided on the motor, lubricate every six months with SAE-10 weight,
non-detergent oil. Inspect the motor and blower assembly every time the motors are
oiled for excessive accumulation of dust and dirt. If necessary, remove the blower
and vacuum. If this situation does occur, increase routine filter maintenance.
“DO
NOT OVER OIL”
o
Check amperage draw against the nameplate information
o
Check bearings for wear and noise.
o
Wheel – Check for free spinning movement
o
Check for tightness of set screws.
o
Check blades for damages.
Drain Pan (Annually)
o
The drain pan must be inspected before summer operation. All debris in the drain
pan should be removed so the condensate will flow out easily. Periodic inspection of
the drain pan and condensate piping should be performed during the summer
