Maintenance

 WARNING

Warnings indicate potentially hazardous situations, which can result in 

property damage, severe personal injury, or death if not avoided. 

 CAUTION

Sharp edges and coil surfaces are a potential injury hazard. Avoid contact 

with them.

Always isolate the unit electrically before removing the front 

access panel. Do this by opening the circuit breaker (or other 

switching device) in the distribution panel in the suite. Do not 

use the fan switch as the means of isolation. There is a high 

risk of electrocution if the unit is improperly isolated. If in doubt 

have a qualified electrician perform the service work.

Ensure that the fan has stopped rotating before proceeding to 

work within the unit. If the unit is equipped with a fuse or circuit 

breaker, do not change out either of these devices with ones of 

a higher Amp rating. The purpose of a fuse or circuit breaker is 

to protect the power wiring to the unit.
Take care when working inside the unit. Sheet metal 

components may have sharp edges.

If the black acrylic coating on the glass fiber cabinet liner is 

damaged, it must be patched to prevent glass fiber particles 

entering the air stream.

Every 3 Months

• 

Check/replace the filter 

The filter can be one of two types: a 1" thick cardboard 

framed type or a metal frame with filter media attached.
Units with a hinged filter door in the upper half of the grille 

panel – Grasp the bottom edge of the door and sharply 

pull the door forwards. Lift the door to the horizontal 

position. The filter is now accessible and is removed by 

sliding it upwards out of the channels attached to the coil.

Annually

(before the start of the cooling season)

•  Remove the return air/access panel from the wall. 

Remove the two sheet metal screws which secure the 

panel that shields the fan assembly. Pull the shield panel 

sharply downward and remove.

•  Vacuum the drain pan and check that the drain outlet is 

not blocked. Pour water into the pan and check that it 

drains quickly. If it appears to be partly blocked, remove 

and clean the drain hose beneath the pan.

•  If the coil surface is dirty, vacuum the surface which faces 

the room. Take care not to damage the aluminum fins on 

the coil. If the fins are flattened, the performance of the 

unit will be reduced.

•  Inspect the surface of the cabinet liner for evidence of 

dampness. The liner should be completely dry in all 

areas. Vacuum excessive dust from the liner, taking care 

not to damage the black acrylic coating on the liner. Do 

not run the unit if the liner is damp as this can promote 

mold growth. Determine the cause of the dampness. If 

there is evidence of mold growth it might be necessary 

to replace part or all of the liner. If in doubt consult a 

remediation specialist.

•  Fan, fan motor, control valve(s), electric heater, drain pan 

over-flow switch, and thermostat do not require routine 

maintenance.

NOTE: 

Fan motor has sealed bearings and does not require 

additional lubrication.
