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 fin pack.  Use a sweeping 

up and down motion in the direction of the vertical 

aluminum fin 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.

Inspect the indoor blower and its 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.

Periodically (at least yearly or bi-yearly): inspect 

all control components: electronic, 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.  

The motor is permanently lubricated.

The air filter should be inspected weekly and cleaned 

if needed by vacuuming with a dust attachment or 

by cleaning in the sink using warm water and a mild 

dishwashing detergent. Dry the filter thoroughly before 

reinstalling. Use caution as the coil surface can be sharp.
TO REMOVE, WASH AND REPLACE FILTER 

Lower front panel. Use handle on filter to flex filter 

up and out of retainer. Remove filter from unit. Clean 

filter monthly or more frequently if needed. Refer to 

accessories section for filter options.

Units are to be inspected and serviced by qualified service 

personnel only. Use proper protection on surrounding 

property.  Failure  to  follow  this  notice  could  result  in 

moderate or serious property damage.

Use two people to lift or carry the unit, and wear 

proper protective clothing.

Failure to do so may result in personal injury.

Do not use a caustic coil cleaning agent on coils or base 

pan. Use a biodegradable cleaning agent and degreaser, 

to prevent damage to the coil and/or base pan.

Turn off electric power before inspections, 

maintenances, or service. 

Extreme care must be used, if it becomes 

necessary to work on equipment with power 

applied.

Failure to do so could result in serious injury 

or death.

Be careful with the sharp edges and corners. 

Wear protective clothing and gloves, etc.

Failure to do so could result in serious injury.
