AIR FILTER 

Clean the unit air intake filter at least every 300 to 350 hours of operation. Clean the filters with a mild detergent in  

warm water and allow to dry thoroughly before reinstalling. 

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.

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.

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. 

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.  

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

proper protective clothing.

Failure to do so may result in personal injury.

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.

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 elec-

trical tests. Use an air conditioning or refrigeration thermometer to check room, outdoor and coil operating tempera-

tures. Use a sling psychrometer to measure wet bulb temperatures indoors and outdoors. 
Inspect the surrounding area (inside and outside) to ensure that the unit’s clearances have not been compromised or 

altered. 

Be careful with the sharp edges and corners. 

Wear protective clothing and gloves, etc.

Failure to do so could result in serious injury.
