Maintenance Procedures

Perform the following maintenance procedures to ensure proper unit operation.

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Chassis

Clean the chassis every four months or more often as the atmospheric conditions require. Use water and detergent to clean the basepan, center partition and coils.

Using harsh cleaning materials may cause a deterioration of the coil fins or end plates.

Do not use a high pressure cleaner as it could cause severe damage to the PTAC fins and coils.

Note: It is very important to not get any of the electronic parts wet.

A hose is okay to use to clean the coils, but make sure to cover the control with a blanket or plastic bag to prevent it from getting wet.

Wall Sleeve

Clean the wall sleeve every four months or more often as the atmospheric conditions require.

Remove any debris from the bottom of the panel, and from around any internal or external drain kit accessory item prior to using water or detergent. This will ensure that no debris clogs up the drain holes.

The use of harsh cleaning materials may cause a deterioration of the bottom panel over time. Do not use a high pressure cleaner because it could spray the side or top panel insulation material and cause future air quality problems like mold and mildew.

Clean side and top panel insulation material with a lint brush or piece of tape. Press tape against insulation lightly and slowly peel away to remove dirt and debris.

Compressor/Fan Motor

The compressor and fan motor are hermetically sealed, permanently lubricated, and require no additional oiling.

Cabinet Front

The cabinet front and discharge air grille can be cleaned with a mild soap or detergent.

Under NO circumstances should hydrocarbon based cleaners (e.g. acetone, benzene, naphtha gasoline, etc.) be used to clean the front or air grilles.

Use care when cleaning the control area. Do not use an excessively wet cleaning cloth.

Intake Air Filter

The intake air filter and vent door filter are both constructed of durable polypropylene. Clean filters monthly to ensure proper unit operation.

The fan must be off before the filters are cleaned.

To remove the air filters, grasp the top of the filter and lift out of the front cabinet (Figure 19.) Reverse the procedure to reinstall the filters.

Figure 19. Intake air filter removal is through top of unit. Inspect and clean filters monthly for proper unit operation.

Vent Filter

Before cleaning the vent filter, disconnect power to the unit by unplugging the power cord at the wall outlet or subbase, or disconnect power at the fuse box or circuit breaker. If unit is operated with vent door closed, the vent filter does not need to be cleaned.

1.Remove the cabinet front as described in front removal.

2.Remove the six screws securing the chassis to the wall sleeve with a Phillips-Head screwdriver.

3.Slide the chassis out of the wall sleeve far enough so that the vent filter is accessible as shown in Figure 20.

4.Remove the vent filter by unscrewing the two screws at the top of the filter and gently pulling the filter away from the partition panel. Refer to Figure 21. The filter can be cleaned by running under a low pressure hose or sink faucet.
