WARNING

DAMAGE HAZARD

GENERAL

The high wall fan coil unit provides quiet, maximum comfort. In addition to cooling and/or heating, the high wall fan coil unit matched with an outdoor condensing unit will filter and dehumidify the air in the room to provide maximum comfort.

IMPORTANT: The high wall fan coil unit should be installed by authorized personnel only; using approved tubing and accessories. If technical assistance, service or repair is needed, contact the installer.

The high wall fan coil unit can be set up and operated from the remote control (provided). If the remote is misplaced, the system

can be operated from the “Auto” setting on the unit.

Operating Modes:

The high wall fan coil unit has five operating modes.

S Fan only S Auto S Heating S Cooling S Dehumidification (DRY)

Fan Only

In Fan Only mode, the system filters and circulates room air without changing room air temperature.

Auto

In Auto mode, the system will automatically cool or heat the room according to the user- selected set point.

Heating

In Heating mode, the system heats and filters room air.

Cooling

In Cooling mode, the system cools, dries and filters room air.

Dehumidification (DRY)

In Dehumidification mode, the system dries, filters and slightly cools room air temperature. Use of this mode does not take the place of a dehumidifier.

Remote Control

The remote control transmits commands to set up and operate the system. The control has a window display panel that shows the current system status. The control can be secured to a surface when used with the mounting bracket provided.

distance of up to 25 ft. (7.6 m) as long as there ar e no obstructions. This is one way communication only (from remote control to fan coil).

The remote control can perform the following basic functions:

S Turn the system ON and OFF

S Select operating mode

S Adjust room air temperature set point and fan speed

S Adjust airflow direction

Battery Installation

Two AAA 1.5 v alkaline batteries (included) are required for operation of the remote control.

To install or replace batteries:

1. Slide the back cover off the control to open the battery compartment.

2. Remove old batteries if you are replacing the batteries.

A08299

NOTE:

1. When replacing batteries, do not use old batteries or a different type battery. This may cause the remote control to malfunction.

2. If the remote is not going to be used for several weeks, remove the batteries. Battery leakage may damage the remote control.

3. The average battery life under normal use is about 6 months.

4. Replace the batteries when there is no audible beep from the indoor unit or if the Transmission Indicator fails to light.

REMOTE CONTROL MATCHING

The System require the wireless remote controller to be matched to the indoor High wall unit before beginning any operations, othe rwise the indoor High wall unit will not accept commands from the remote controller. Follow the instructions below to automatically match the remot e controlle r to the indoor high wall unit:

1. Turn on electrical power to the indoor and outdoor units. The indoor high wall unit powers up in the Off (or Sta ndby) mode.

2. Hold the remote controller 5 to 6 feet from the indoor high wall unit.

3. Point the remote controller at the indoor wall unit and press the Blank button for 3 seconds.

4. The indoor high wall unit provides 3 beeps to signal a successful match.

5. Press the Power ON button on the remote controller. The green indicator light displays on the indoor high wall unit.

6. The remote controller is matched and ready for use. If the indoor unit and remote controller fail to match, check the remote controller batteries, move closer and repeat the matching process again.

NOTE: This is a one- time requirement only. The remote controller and indoor high wall unit need to be successfully matched only o nce.

CLEANING, MAINTENANCE AND TROUBLESHOOTING

CAUTION

ELECTRICAL SHOCK HAZARD

Failure to follow this caution may result in personal injury or death. Always turn off power to the system before performing any cleaning or maintenance to the system. Turn off the outdoor disconnect switch located near outdoor unit. Be sure to disconnect indoor unit if on a separate switch

CAUTION

EQUIPMENT DAMAGE/OPERATION HAZARD

Failure to follow this caution may result in equipment damage or improper unit operation. Operating the system with dirty air filters may damage the indoor unit and could cause reduced cooling performance, intermittent system operation, frost build- up on indoor coil or blown fuses.

Periodic Maintenance

Periodic maintenance is recommended to ensure proper operation of the unit. Recommended maintenance intervals may vary depending on the installation environment, e.g., dusty zones, etc. Refer to Table 1.

CAUTION

CUT HAZARD

Failure to follow this caution may result in personal injury.

The coil fins are very sharp. Use caution when cleaning.

Always wear safety protection.

Cleaning the Coil

Clean the coil at the beginning of each cooling season, or when necessary. Use a vacuum cleaner or a long- bristle brush to avoid damage to the coil fins.

Air Filters

Remove and clean the air filters once a month. NOTE: If air filters show signs of excessive wear or are torn, they must be replaced. Contact your local dealer for replacement filters.

1. Open front panel on unit.

2. Pull filters down to remove.

3. Vacuum filters.

4. Clean with warm water.

5. Shake filter to remove excess water and dry thoroughly.

6. Replace filter by sliding into rack until filter snaps in place.

7. Close front panel on unit.

CAUTION

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage. When cleaning the front panel, do not use water hotter than 105_F (40.56_C) and do not pour water onto the fan coil. Do not use abrasive or petroleum based cleaners as they may damage the front panel.

Indoor Unit Front Panel

To clean the front panel on the indoor unit, wipe the outside with a soft, dry cloth. If necessary, a mild liquid detergent can be applied and wiped off with a dry cloth.

Preparing for Extended Shutdown Period

Clean the filters and reposition them in the unit. Operate the unit in Fan only mode for 12 hours to dry all internal parts.

Turn main power supply off and remove batteries from the remote control.

System Operation Recommendations

The items outlined in the following list helps to assure proper system operation:

S Replace both remote control batteries at the same time. S Point the remote control toward the unit display panel when

transmitting a command.

S Keep doors and windows closed while unit is operating. S Contact an authorized service representative if a problem arises

that cannot be easily resolved.

S Do not perform cleaning or maintenance activities while unit

is on.

S Keep display panel on unit away from direct sunlight and heat

as this may interfere with remote control transmissions.

S Do not block air intakes and outlets on the indoor or outdoor

units.

Energy Saving Recommendations

The following recommendations add greater efficiency to the ductfree system:

S Select a comfortable thermostat setting and leave it at chosen

setting. Avoid continually raising and lowering the setting.

S Keep unit filter clean. Frequent cleaning may be necessary

depending on indoor air quality.

S Use drapes, curtains or shades to keep direct sunlight from

heating room on very hot days.
