ROUTINE MAINTENANCE

NOTE:  Units are to be inspected and serviced by qualifi ed service personnel only.

 

Inspect the indoor blower housing, evaporator blade, condenser fan blade, and condenser shroud periodically (yearly or 
bi-yearly) and clean of all debris (lint, dirt, mold, fungus, etc.)  Clean the blower housing area and blower wheel with an 
antibacterial / antifungal cleaner.  Use a biodegradable cleaning agent and degreaser on condenser fan and condenser 
shroud.  Use warm or cold water when rinsing these items.  Allow all items to dry thoroughly before reinstalling them.

3. 

Periodically (at least yearly or bi-yearly): inspect all control components, both electrical and mechanical, as well as the 
power supply.  Use proper testing instruments (voltmeter, ohmmeter, ammeter, wattmeter, etc.) to perform electrical 
tests.  Use an air conditioning or refrigeration thermometer to check room, outdoor and coil operating temperatures.  
Use a sling psychrometer to measure wet bulb temperatures indoors and outdoors.

4. 

Inspect the surrounding area (inside and outside) to ensure that the units’ clearances have not been compromised or 
altered.

5. 

Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris.  
Clean both areas with an antibacterial and antifungal cleaner.  Rinse both items thoroughly with water and ensure that 
the drain outlets are operating correctly.  Check the sealant around the sleeve and reseal areas as needed.

6. 

Clean the front cover when needed.  Use a mild detergent.  Wash and rinse with warm water.  Allow it to dry thoroughly 
before reinstalling it in the chassis.

Routine maintenance is required annually or semi-annually, depending upon annual usage.
1. 

Clean the unit air intake fi lter at least every 250 to 300 fan hours of operation or when the unit’s indicator light is on if 
so equipped.  Clean the fi lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.

2. 

The indoor coil (evaporator coil), the outdoor coil (condenser coil) and base pan should be inspected periodically (yearly 
or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper, etc.).  Clean the coils and base pan with a soft brush and 
compressed air or vacuum.  If using a pressure washer, be careful not to bend the aluminium fi n pack.  Use a sweeping 
up and down motion in the direction of the vertical aluminum fi n pack when pressure cleaning coils.  Cover all electrical 
components to protect them from water or spray.  Allow the unit to dry thoroughly before reinstalling it in the sleeve.

NOTE:  Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.
