Carrier 38AN,BK Cleaning And Maintenance, To Install or Replace Remote Controller Batteries

CLEANING AND MAINTENANCE

To avoid the possibility of electric shock, before per- forming any cleaning and maintenance operations al- ways turn off power to the system by pressing the

orange ON/OFF button on the remote controller. Turn off the outdoor disconnect switch located near the out-

door unit. If the indoor unit is on a separate switch, be sure it is also disconnected.

For proper system operation, perform the cleaning and main- tenance operations in Table 9.

Lubrication -- The indoor-fan automatic air sweep mo- tor, and the outdoor-fan motor are factory lubricated and re- quire no oiling.

To Install or Replace Remote Controller Batteries

Do not drop the remote controller -- damage to the de- vice may result. Avoid getting the controller wet.

NOTE: Before replacing the batteries, note that the remote controller signal can be affected if electronic fluorescent lights are installed nearby. The batteries may not need to be

replaced. If you suspect this is the problem, consult your Carrier distributor.

Batteries should be replaced once a year. Use 2 batteries (1.5 v, dc-type, AAA alkaline batteries). Never use old or recharged batteries together with new ones.

To replace batteries:

When shutting down the system for an extended period of time, it is advisable to remove the batteries.

Consult distributor if any other equipment is turned on or shows signs of disrupted operation if you use the wireless remote controller, or if the system is turned on or shows signs of disrupted operation when the remote controller of any other equipment is used.

To Set the Current Time

1. Press the _ button (located on the back of the remote

controller; see Fig. 19) with an instrument screwdriver or similar small, pointed tool, and the current time indica- tion symbol flashes.

Note that the controller comes preset from the factory set for 6:00 a.m.

2.Set the current time with the hour and minute buttons on

the front of the remote controller (see Fig. 19) while the current time indication is flashing. Note that a.m. and p.m. are also indicated as the times are scrolled through.

3.Press [] again. The flashing will stop and the current time will be reset to the new setting.

To Remove and Clean or Replace Air Filters

Operating your system with dirty air filters may damage the indoor unit and can also cause reduced cooling per- formance, intermittent system operation, frost build-up on the indoor coil, and blown fuses. Inspect and clean or replace the air filters monthly.

TO REMOVE AIR FILTERS:

1.Slide the battery cover off from the back of the remote controller. See Fig. 18.

2.Insert the 2 batteries in accordance with the markings on the remote controller, so that the poles are correct (+ and -).

3. Press the [_ button using an instrument screwdriver

or similar small, pointed tool.

4. Replace the cover securely.

It is time to replace the remote controller batteries when the remote controller function becomes irregular, or the sys- tem no longer responds to commands given close to the unit.

1.Open fan coil unit front panel (lift). See Fig. 20.

2.Pull the filters down to remove.

TO CLEAN OR REPLACE FILTERS -- Filters should be vacuumed and washed with warm water (see Fig. 20). Shake filter to remove any excess water, dry thoroughly, and re- place by sliding filter behind front grille until filter snaps in place.

If the filter has begun to break down or is torn, it needs to

be replaced. Replacement filters are available through your Cartier distributor.

NOTE: DO NOT put filters in the dishwasher.
