REPLACEMENT PARTS SOURCE
Replacement parts are available through local distributors.When ordering replacement parts, give
the COMPLETE model and serial numbers shown on the rating plate.
INSTALLATION REQUIREMENTS
Before installing this appliance insure that it is properly sized and adequate power is available.
This appliance can be installed in the vertical or right horizontal position without modification.
The horizontal left and downflow positions require product modification.
This product is designed for zero inch (0") clearance; however, adequate access for service or
replacement must be considered without removing permanent structure. This unit can be installed
on a platform when deemed necessary.
In an attic installation a secondary drain pan must be provided by the installer and placed under
the entire unit with a separate drain line properly sloped and terminated in an area visible to
the owner. This secondary drain pan is required in the event that there is a leak or main drain
blockage. Closed cell insulation should be applied to the drain lines in unconditioned spaces
where sweating may occur.
Appliances installed in garages, ware houses or other areas where they may be subjected to
mechanical damage must be suitably guarded against such damage by installing behind protective
barriers, being elevated or located out of the normal path of vehicles. When installed on a base,
the base must also be protected by similar means.
Heating and cooling equipment located in garages, which may generate a glow, spark or flame
capable of igniting flammable vapors, must be installed with the ignition source at least 18"
above the floor level.
When more than one appliance is installed in a building, permanently identify the unit as to
the area or space serviced by that applice.

(see page 6)
Important:
Remove the horizontal pan when
unit is installed in unconditioned
i.e. (Garage, Attic ) application,
or downflow applications, and
install insulation kit on vertical
( donut shape ) drain pan.
*Upflow Discharge
*Air Handler is factory ready for Upflow & Horizontal Right Discharge Application for 3*4*5 as shown.
*Air Handler is factory ready for Upflow & Horizontal Left Discharge Application for 2 as shown.

HORIZONTAL LEFT-HAND INSTRUCTIONS
Important: Read instructions below carefully.
WARNING: If incorrect knockouts are removed, flooding will occur.
5) Reinstall in the Airhandler, the "A" coil pan assembly with the horizontal drain pan on the
left-hand side.
Note: Push the assembly completely to the rear of the cavity and assure it slips into channel
bracket at the rear of the cavity.
6) Replace the J-shape metal bracket or brackets on the vertical drain pan and place the
plastic oval gasket on horizontal drain pan. Reinstall access panels and flowrator making
sure not to over torque screws. Snap in the drain cover on the right lower service panel.
7) The Airhandler can now be placed in its left horizontal position as shown in Fig.2. The
Airhandler must be leveled and then pitched 1/4" toward drain side. Important: Drain pan
must be tested for proper drainage by pouring water into the pan. Traps must be installed
on the primary drain and on the secondary drain if used.
8) In all cooling applications, a secondary drain pan must be provided by the installer and
placed under the entire unit with a separate drain line properly sloped and terminated in an
area visible to the user.
9)
Before setting up flowrator assembly for field brazing see page 12 or read the Warning
label on the lower access panel.
10) Failure to follow this installation requirements will cancel product warranty.

REFRIGERANT TUBING
CONDENSATE REMOVAL
Refrigerant tubing should be installed as to avoid undue stress. They must be supported or
routed to avoid strain or vibration. To avoid damage that can be caused by condensate,
insulate the suction tube with a closed cell insulation with the seams sealed. The insulation
should terminate at the tubing entrance to the air handler. Do not reduce the recommended
tubing size.
THIS APPLIANCE EMPLOYS A DRAW-THROUGH COIL, THEREFORE A
TRAP MUST BE INSTALLED IN THE DRAIN LINE(S) TO ALLOW FOR
PROPER CONDENSATE DISPOSAL.
The condensate trap must not be the "running" type, or "R" type. A "P " trap is required.
The total workable height of this trap, in inches, must exceed the total negative pressure,
in inches of water, as measured in the return duct.
The condensate drain line must be at least 3/4 NPT, for each unit. Precautions must be
used not to over tighten the adapter at the drain pan connection, this precaution will
prevent damage to the plastic drain pan. A joint compound should be used to prevent
leakage and act as a lubricant.
When using copper tubing as a condensate line adequate caution muat be taken to prevent
damage to the plastic drain pan during the soldering process. All condensate drain lines
and drain traps should be adequately insulated.
The unit and the auxiliary drain pan must be adequately elevated to insure proper drainage.
Use of a condensate removal pump is permitted when necessary.This condensate pump
should have provisions for shutting off the control voltage should a blocked drain occur. A
trap must be installed between the unit and the condensate pump. Important: The evaporator
coil is coated with oils that will dissolve Styrofoam and certain types of plastics. Therefore
a removal pump or float switch must not contain any of these materials.
NOTE: AFTER INSTALLATION AND POSITIONING THE UNIT , THE DRAIN
PAN BEING USED SHOULD BE TESTED BY FILLING IT WITH WATER TO
ENSURE PROPER DRAINAGE AND CHECK FOR LEAKS.

ELECTRICAL CONNECTIONS
The required electrical power supply information is located on the series and rating plate
on the exterior of the unit. Wiring selection must be in accordance with local codes, or in
absence of local code, the National Electrical Code. A disconnect means should be installed
within sight of the unit, when required by code.
Copper wire is recommended for all electrical connections.
When an optional heat kit is installed refer to the electrical requirements in that kit.
The wiring diagram included in the heat kit must be placed over the wiring diagram on the
air handler.
All pertinent information, such as the rating plate, included in the optional heat kit must be
applied to the Air Handler as indicated.
The use of copper connections are recommended inside the control box (see UL 1995,
section 37.9).
WARNING
A MEANS OF STRAIN RELIEF MUST BE INSTALLED TO THIS APPLIANCE AT
THE ELECTRICAL SERVICE ENTRANCE.
When an optional electric heat kit is installed refer to the electrical requirements for that
kit. The ampacity and overcurrent protection shown above is only for "HB" air handlers
installed without a heat kit.
