General Information
These instructions cover installation, operation, and mainte-
nance of all single package
TCH024-060
air conditioning units.
For an easy and orderly installation, follow the sequence of
instructions as they are outlined. Improper installation can
result in unsatisfactory operation and/or dangerous conditions
as well as make the related warranty inapplicable. Read this
manual carefully before installing, operating, or performing
maintenance on this unit. Installation and maintenance should
be performed by qualified service technicians. Locate the unit in
accordance with local codes or the National Electrical Code. Each
unit contained an operating charge of HCFC-22 when shipped.
Unit Inspection
The material in this shipment has been inspected at the factory
and was released to the transportation agency without known
damage. Inspect the exterior of the carton for evidence of rough
handling in shipment. Check the unit nameplate to determine if
the unit is correct for the intended application. After moving the
equipment to the approximate location, unpack it carefully. If
damage to the unit is found, report the nature of this damage
immediately to the delivery agency. Check to be sure that the
refrigerant charge has been retained during shipment.
Power Supply
The power supply must be adequate for the unit and any
supplementary electric heaters, if added. Make certain that the
power supply to the unit agrees with the power requirements
specified on the unit nameplate. Separate branch circuits are
required for supplementary electric heaters.
Rigging
IMPORTANT:
Check the handling facilities to ensure the
safety of both personnel and the unit. Be sure that the proper
method of rigging is used, with straps or slings and spreader bars
for protection during lifting.
Access and service clearances for the unit must be given careful
consideration when locating the duct entrance openings.
Figure 1 provides unit dimensions.
All fabricated outdoor ducts should be as short as
possible.
Be sure the openings in the structure are large enough to
accommodate the ducts and the insulation surrounding them.
See Figure 1.
For outdoor, ground level applications the unit must be mounted
on a solid, level foundation that is not adjoined to the structure
because sound and vibration may be transmitted to the struc-
ture.
Field supplied mounting pads should be placed beneath the unit
to prevent transmission of vibration to the occupied structure.
Select a location that will minimize the length of the supply and
return ducts.
Select a location where external water drainage cannot collect
around the unit.
Give consideration to shade, appearance, and noise.
This unit was designed for multiple applications: rooftop, out-
door ground level. For proper installation, the following recom-
mendations must be considered:
Installation of the unit should conform to local building codes or,
in the absence of local codes, to the National Electrical Code.
Canadian installations must conform to CSA and local codes
Select a location that will permit unobstructed airflow into the
outdoor coil and away from the fan discharge. The discharge air
from the outdoor fan must be unrestricted for a minimum of three
(3) feet above the unit. Any reduction of the unit clearances
recommended may result in condenser coil starvation or the
recirculation of warm condenser air. Actual clearances which are
inadequate should be reviewed with a local sales representative.
If the unit is located under an overhang, provisions must be made
to deflect the warm discharge air from under the overhang. See
Figures 1, 2 and 3. The unit must also be situated to permit easy
and unrestricted access for service.
Install internal accessories to the unit at the shop if practical.
Position the unit so roof-run-off water does not pour directly onto
the unit.
CAUTION MUST ALWAYS BE TAKEN TO AVOID PERSONAL
INJURIES AND/OR DAMAGE TO THE EQUIPMENT.
Elevation minimums must be observed for drain line "trap" and
ventilation to the under side of the unit.
All duct work inside the structure should be adequately insu-
lated.
All duct work outside of the structure must be insulated and
weatherproofed in accordance with local codes. If supplementary
heat is added, the duct connectors should be of a flame retardant
material.
