2. Pull panel forward then upward to release magnetic latches and partition hooks.
NOTE: Front panel may be secured to chassis with 2 screws located behind indoor air inlet filters. In order to remove
these screws, tire filters must be removed first. Refer to page 8 in this manual for" instructions on removing indoor air
inlet filters. IMPORTANT: The fl'ont panel has to be off the unit to corn
plete flmlre checks and installation procedures. Do not reinstall front panel at this time.

To install the fl'ont panel follow the procedure outlined below:
1. Firmly grasp bottom of front panel on both sides.
2. Hold fl'ont panel at a 45 degree angle to unit. Be sure fl'ont panel is centered with front of unit.
3. Connect top of front panel to partition rail on top of unit.
4. Gently lower fi'ont panel onto chassis, ensuring ser- vice cord is positioned through front panel slot.
NOTE: Magnets on bottom of front panel will secure fi'ont panel to unit.
To install locking feature on fi'ont panel be sure fi'ont panel is already installed on unit and follow the steps below:
NOTE: Two field supplied no. 8, 1/2in. sheet metal screws are required to secure front panel to chassis.
1. Remove both indoor air inlet filters to expose fi'ont panel engagement holes. See Fig. 4,
2. Secure front panel to chassis by attaching the field- supplied screws into engagement holes. /)o not over"
t_ghten.
3. Replace both indoor air inlet filters.
NOTE: Front panel alignment may have to be adjusted slightly to line with chassis.
ELECTRICAL DATA
Be sure that your outlet matches the appropriate blade con- figuration of the supplied plug and that it is within reach of
the service cord. A hardwire kit is available as an accessory to change cord-connected units to hardwired units. (See
Accessories table on page 11.) IMPORTANT: All standard cord connected 265 v units will
require a field-installed electrical subbase accessory

NOTE: Use copper conductors only, B. Grounding
For safety and protection, the unit is grounded through the service cord plug or through separate ground wire provided
on hardwired units. Be sure that the branch circuit or gen- eral purpose outlet is grounded.

II. VOLTAGE SUPPLY
Check voltage supply at outlet. For satisfactory results, the voltage range must always be within the ranges found on the
data information plate (Fig. 1).
A. Cord-Connected Units
The 250-v field-supplied outlet nmst match the plug fox"the standard 208/230 v units and be within reach of the service
cord. The standard cord connected 265 v units require an accessory electrical subbase for operation. See Accessories
table, page 11, for subbase selection. Refer to Table 2 for proper receptacle and fuse type.

INSTALLATION
I. CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended that a 84 series
wall sleeve be used. The 84 series units can retrofit General Electric, Amana, Trane, Bryant, Friedrich and Carrier
sleeves/grilles (be sure outdoor grille is installed on the sleeve). See Table 3 fox"details.
For competitive retrofit applications, be sure that the foam seals (factow-installed on tube sheets) provide a good seal
between the grille and condenser coil tube sheets, These foam seals prevent air recirculation (outgoing air mixing
with incoming air) which can cause premature damage to major components. See Fig. 5-7.
NOTE: Inspect wall sleeve fox"any damage or deterioration before installing chassis.
