What do I need to know and remember?

It is important to know and remember the following, with regard to Window Room ACs.

How can I reduce power consumption while maximizing comfort?

These economy tips can help maximize comfort and reduce power consumption.

Set thermostat to a setting consistent with the comfort level you desire. Once you have determined the setting, do not change.

Keep the filter clean. Normally, cleaning once every month should be adequate but depending upon the environment, more frequent cleaning may be necessary. The filter is efficient in trapping airborne particles and on inspection may reveal the need for cleaning.

Use drapes, shades, venetian blinds etc. to prevent direct sunlight from heating the room.

Keep doors and windows properly shut.

Do not block the front of the unit with furniture or other articles.

Remember: Even without the above, your air conditioner is designed to be highly energy efficient.

Over and above you can opt to install Electronic remote kit for temperature settings.

What else do I need to be aware of?

The following points also need to be remembered.

The unit is designed to operate with a power supply of 230 Volts; 50 Hz; single phase. Supply voltage should be within 187 to 235 Volts. In case there is variation beyond this range, a voltage stabilizer is required to be used.

Condensation on grille may occur on busy humid days. Keep doors and windows properly closed to prevent outside humid air from entering the room.

Your air conditioner is designed to operate up to 46o outside temperature, provided the room temperature does not exceed 27C. However, the capacity is rated at 35o outdoor temperature and 27o room temperature.

Remember: Even without the above, your air conditioner is designed to be highly energy efficient.

What care and maintenance tips do I need to keep in mind?

You need to keep the following care and maintenance tips in mind.

Cleaning the Filter:

Before cleaning the air filter, turn the air conditioner off. A clogged filter could result in reduced cooling, frost on evaporator coil or tripping of the unit. Take a few minutes every month (more often if necessary) to clean the filters.

To remove the filter, hold the filter frame as shown in the sketch and pull downward. The filter will slide out.

Clean the filter using a vacuum cleaner or in tap water.

Shake the filter dry.

Slide it back into the front grille, till it clicks in place.

Cleaning the Unit:

Clean the unit periodically to keep it looking new using a soft cloth dampened with mild detergent ('Teepol' is the recommended detergent. Thereafter, wipe clean with a dry cloth.


Do not use bleaching powder, hot water, thinner, petrol or any other chemical for cleaning. This will damage the unit.

Do not wash the unit to avoid serious electrical shock.

Turn the main switch off before cleaning.

Avoid continuous direct airflow on occupants particularly in case of infants and patients.

When not in use, switch off the electric supply to the unit.

What are the general precautions I should follow?

The general precautions you need to follow are :

Before performing service or maintenance operations on the system, turn off main power to the unit. Electrical shock can cause personal injury.

Check the power plug. If the power plug is not inserted tightly, or if there is any damage to the power cord, it could result in leakage or electrical shock.

Use the correct voltage. Using voltage other than that specified will damage the unit.

Do not use the power cord as a means of turning off the unit.

Do not use flammable sprays near the unit.

When unplugging the power plug, do not pull it by the power cord.

To avoid the risk of serious electrical shock, never splash the indoor and the outdoor unit with water.

Do not put hands or objects into the discharge grille of the outdoor unit. These units have a fan running at very high speed. It is very dangerous to touch the fan.

Use only fuses of the proper amperage.

Be careful to keep the room temperature comfortable. Avoid continuous direct air-flow on the occupant, especially in case of those sleeping or an occupant.

Do not obstruct the front of the discharge grille of both units. This will block air flow, reduce the cooling effect, and may result in malfunction.

Ventilate the room air when the room becomes stuffy or filled with undesirable odours.

Keep heat sources away from the unit. High temperatures can cause damage.

Set a comfortable temperature. Very low temperature settings considerably increase power consumption.

If you want to merely circulate room air, operate the FAN mode.

In summer, if possible prevent direct sunlight from entering the room; draw curtains or blinds.

Use the timer correctly to maintain comfort conditions.

What should I keep in mind before operating a hi-wall unit?

Keep the following in mind before operating a hi-wall unit.

The air conditioner will not operate if curtains, doors or other materials block the signals from the remote controller to unit.

If the infra-red signal receiver on the unit is exposed to direct sunlight, the air conditioner may not work properly. Draw the curtains to avoid direct sunlight.

Avoid spilling liquid on to the remote controller or dropping it. This can cause deformation, discoloration and malfunction.

A mounting bracket for the remote controller is supplied with the unit. Install the mounting bracket on the wall 30-cm below the receiver of the unit.

What do I need to know about care and maintenance?

The following need to be kept in mind, about the care and maintenance of your AC:

There are certain temperature ranges which are suitable for unit operation. These are:

Mode Indoor Outdoor

Cool 21-32°C 21-43°C

Dry 17-32°C 12-43°C

When the unit is operated above or below these conditions for a long time, system diagnostics may detect a malfunction and the unit will not operate properly. If the unit is operated for a long time under abnormal situations of extremely high humidity, condensate water may drip from the unit

For cleaning the main unit, use only a damp, soapy towel. Do not pour water on to the unit, and do not use petrol, solvents or abrasive power resulting in damage of the unit.

After-season care is important. Clean the filters and refit into the unit. If the unit is to be switched off for an extended period, run the unit on FAN only for a half a day to dry inside of the unit. Disconnect the power cord. When you are using a power circuit solely for the air conditioner, turn off the power on that circuit. Clean the indoor and outdoor unit and wrap the outdoor unit with a protection cover.

Clean the filters once a month. To do this, lift the front panel and pull out the air filters downward. Clean them with a vacuum cleaner. Rinse them under running water and dry them completely before refitting them into their guides.

How can I save on the sales tax?

By buying a Carrier model Ex-Daman (where we have our factory in the tax-exempted zone). This will mean an additional wait of approx. 2 weeks for delivery of the unit.
