For some people, air conditioning maybe a luxury, but for many, it is anecessity. It is important to keep our airconditioner always in a good conditionconsidering its benefits for us, i.e.maintaining suitable humidity in all partsof a building, freeing the air fromexcessive humidity during certainseasons, supplying a constant andadequate supply of ventilation,efficiently removing from the airmicro-organisms, dust, soot, and otherforeign bodies, efficiently cooling roomair during certain seasons, heating orhelping heat the rooms in winter, andrenewing and improving air quality

Unplug theair conditioner. Disconnect the power

from the unit.

Remove the filterand

bezel or cover of the

unit if needed.Remove the filter to exposethe cooling coils.

Aditionally, some modelsrequire that the front coveror bezel be removed to allowfull access to the coil.

Usually the cover is secured By screws - some of whichbecome visible only when theter is removed.

Spray the front coil ofthe air conditioner witha cleaning agentdesigned for this use. Home Depot and many other

home supply centers andhardware stores sell productsexpressly for this particular job

These cleaners will help removeodors from deposits of dirt,mold, mildew, cigar & cigarettesmoke, etc. from the coils.

Use care to see that only thecoils are covered with thecleaner.

Foaming type cleaners willwork best only when used asdirected.

Prevent foam from sprayingelectrical wires, controls or other parts.

Clean the filter. Clean the ter with plainwater or replace if missing.

A clean ter is a must. It is far easier and cheaper to remove andclean the ter every 15 hours (more or less depending of dust /dirt levels in the space) than to clean the air conditioner with afoaming cleansing

If the filter is suspected of contributing to odors,soak and wash with a small amount of scenteddish soap or laundry detergent.

Repeat if necessary.

In low humidityconditions, it will takelonger to rinse the coils.

If the unit fails to make coolair, it has likely lost therefrigerant charge or thecompressor has failed.

wait until the coils are free from foam before re-applying

if the air conditioner has beenneglected, it may require a second application to produce cold air and be free of odors.

If the unit makes cool air butfails to make condensate towash the coils, it may be dueto low of humidity.

Shut the unit off and

disconnect power.

Inspect theoutdoor coils.

Clean the outdoor

coils if desired. The outside coils are exposedto rainwater and may not needcleaning.

If unsure, or in a dusty ordirty area, it may help toclean them.

Apply foaming cleaner with theuntill off. Allow 10-15 minutes forthe foaming cleanser to work.

Inspect theoutdoor coils.

Since no condensate isformed on the outdoor coilwhen the unit is run, it willneed to be rinsed manually.

Do not force a direct a stream ofwater into the coils, but merely allowthe foam to at away as the wateris allowed to ow over the coils.

Reconnect powerand test.

Set to cooling and adjustthermostat to a lowtemperature.

The discharge air should becold and smell clean.
