WLCA/WLHA Controls and Components, Cabinet Features

WLCA/WLHA CONTROLS and COMPONENTS

continued

•Modular design – reduces parts required for control package. Deco panel, relay board, ribbon cables and microprocessor are combined into one package.

•Integral condensate pump safety- switch connection where-by the mi- croprocessor monitors the condensate pump safety switch and displays an error code when a fault occurs. (Applies only with optional condensate pump)

•CEC (California Energy Commission) compliant

•Condensate drain pan over flow protection

Cabinet Features:

•Durable ABS plastic cabinet with a galvanized steel sub-chassis.

•Easily accessible, washable, reusable, nylon mesh filter.

•Horizontal discharge louver, construct- ed of high temperature ABS plastic, that can be set to oscillate, or can be parked in six pre-set positions.

•Manually adjustable vertical discharge fins.

•Easy access to pipe chase area from cabinet bottom allows piping connec- tions and condensate pump installation with the unit mounted on the wall.

•Easily removable end-cap for access to control area for installation and service.

•Condensate drain pan constructed of galvanized steel (G90U), with anti-cor- rosion coating.

•Modular snap-in, 7-day programmable control with large backlit LCD display, a “Change filter” display feature and selectable Fahrenheit (Fº), or Celsius (Cº) temperature scale.

Note: Unit mounted controls are fully func- tional without the remote.

Note: If the control is configured for unit mount control do NOT connect a wall ther- mostat to the unit.

Important: Check equipment for damage prior to installation, if damaged contact the wholesale distributer.

Optional Equipment

•Condensate pump (field installed only)

•24V remote wall thermostat

•Electric heat with automatic reset high temperature cutout and redundant high temperature fuse link (when heat option is selected)

•hand held infrared controller.

Installer Supplied Items

•Low voltage wiring (18 awg required)

•High voltage power supply wiring

•Mounting screws and fasteners

•Condensate piping

•Refrigerant piping (if not supplied)

•Refrigerant (for interconnect charge)

ITEMS FOR CONSIDERATION

Determine the best location for mount- ing the unit for room air circulation.

Locate outdoor and indoor units as close together as possible.

Determine how power wire (high and low voltage) condensate drainage, and refrigerant piping may be run to and from the unit.

WLCA/WLHA - Ensure that intercon- nect tubing is within the maximum allowable length of 100’ including a maximum 35’ lift.

To ensure serviceability and proper air distribution, the unit should be positioned as close as possible to the center (left-to-right) of the wall. Minimum distance from the ceiling is stated on the template provided with the unit packag- ing. The cabinet left and right end caps must be accessible for removal without obstruction. (See below)
