ROUTINE MAINTENANCE

WARNING

ELECTRIC SHOCK HAZARD

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.

WARNING

EXCESSIVE WEIGHT HAZARD

Use two people to lift or carry the unit, and wear proper protective clothing.

Failure to do so may result in personal injury.

WARNING

CUT/SEVER HAZARD

Be careful with the sharp edges and corners.

Wear protective clothing and gloves, etc.

Failure to do so could result in serious injury.

NOTICE

Units are to be inspected and serviced by qualifi ed service personnel only. Use proper protection on surrounding property. Failure to follow this notice could result in moderate or serious property damage.

NOTICE

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.

AIR FILTER

Clean the unit air intake fi lter at least every 300 to 350 hours of operation. Clean the fi lters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.

COILS AND BASE PAN

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 verti- cal 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.

BLOWER WHEEL / HOUSING / CONDENSER FAN / SHROUD

Inspect the indoor blower housing, evaporator blade, con- denser 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 con- denser shroud. Use warm or cold water when rinsing these items. Allow all items to dry thoroughly before reinstalling them.

ELECTRONIC / ELECTRICAL / MECHANICAL

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. Use an electronic tester to measure wet bulb temperatures indoors and outdoors.
