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)
• 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)

• Condensate drain pan over flow
protection
Cabinet Features:
• Durable ABS plastic cabinet with a
galvanized steel sub-chassis.
