systems nor to provide for every possible contingency to be
met in connection with installation. Should further information be
desired or necessary or should particular problems arise which are
not covered sufficiently for the purchaser's or installer's needs or
purposes, the matter should be referred to the manufacturer.

General Information
These instructions
cover installation,
operation,
and maintenance 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.

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

Unit Inspection

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.

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.

Do not lift the unit without
testing for balance and rigging.
Do not lift the unit in windy conditions
or above personnel.
Do not lift the unit by attaching
a clevis, hooks, pins, or bolts
to the unit casing, casing hardware,
corner lugs, angles,
tabs, or flanges. Failure to observe this warning may result
in equipment
damage.

Locations and Recommendations
This unit was designed for multiple applications:
rooftop, outdoor ground level. For proper installation,
the following recommendations
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.

Start-Up

Sequence of Operation
The unit's operation is controlled by the remote room thermostat.
Once the thermostat
is placed in the COOL position, the unit's
operation
is automatic.
A fan switch on the thermostat
also
provides for continuous operation of the evaporator fan if desired.
This is the ON position.
With the fan switch in the AUTO
position, the fan will only operate with the cooling cycle. Continuous fan mode during cooling operation may not be appropriate
in
humid climates. If the indoor air exceeds 60% relative humidity
or simply feels uncomfortably
humid, it is recommended
that the
fan only be used in the AUTO mode.
Cooling
On a call for cooling, the indoor fan "G" and the compressor
circuit'S'
are energized. The indoor fan circuit"G" energizes the
the fan relay coil this closes the fan relay contacts (FDR-1) and
the indoor fan motor(IDFM)
starts. The compressor circuit '5_"
energizes
the (MS) contactor coil this powers the compressor
(CPR) and the outdoor fan motor (ODFM). When the thermostat determines that further cooling is not required, the contactors
are de-energized.
Short Duration
Shut Down
To shut down the unit for a brief period of time, turn the
thermostat
system switch to OFF and place the fan switch in the
AUTO position.
Heating
On a call for heat, the thermostat
'3Y" is energized,
which
connects to unit'%Y", which energizes the "AH" heater contactor
coil. The"AH" contactor closes powering the heater, provided all
element limits are closed.
Note:
The indoor thermostat
must be configured
for electric
heat to provide a"G" signal to energize the indoor fan relay (FDR1) during the heating mode. The heater control circuit will not be
energized unless the indoor fan relay (FDR-2) is energized.
ICM FAN MOTOR ADJUSTMENTS
(TCH048, 060F ONLY)
If the airflow needs to be increased or decreased, see the Airflow
Table in the Service Facts. Information
on changing the speed of
the blower motor is in the Blower Performance
Table.
Blower speed changes are made on the ICM Fan Control mounted
in the control box. The ICM Fan Control controls the variable
speed motor.
There is a bank of 8 dip switches (See Figure 7), located at the
upper left side of the board. The dip switches work in pairs to
match the cooling/heat
airflow (CFM/TON),
Fan off-delay options, and electric heat airflow adjustment.
The switches appear
as shown in Figure 7.

MEASURES

Air Filters
It is very important to keep the central duct system air filters clean. Be sure
to inspect them at least once each month when the system is in constant
operation. In new construction, check the filters every week for the first
four (4) weeks.
•If you have disposable-type filters, replace them with new filters of
the same type and size. Do not try to clean disposable filters.
•Clean permanent-type filters by washing them with a mild detergent
and water. Make sure that the filters are thoroughly dry before reinstalling them in the unit.
•Replace permanent filters annually if washing fails to clean them or
if they show signs of deterioration. Use the same type and size as was
originally installed.

Outdoor

Coil

Unfiltered air circulated through the unit's outdoor coil can cause the
coil's surface to become clogged with dust, dirt, etc. To clean the coil,
stroke the coil surface with a soft-bristled brush vertically, that is, in the
direction of the fins.

• Avoid breathing fiberglass dust.
• Use a NIOSH approved dust/mist respirator.
• Avoid contact with the skin or eyes. Wear longsleeved, loose-fitting clothing, gloves, and eye
protection.
• Wash clothes separately from other clothing: rinse
washer thoroughly.
Operations such as sawing, blowing, tear-out, and
spraying may generate fiber concentrations requiring
additional respiratory protection. Use the appropriate
NIOSH approved respirator in these situations.
FIRST AID MEASURES
Eye Contact

Flush eyes with water to remove dust.
If symptoms persist, seek medical
attention.

•Be sure to keep all vegetation away from the outdoor coil area.

Maintenance Performed by Serviceman
To keep your unit operating as designed, the manufacturer recommends
that a qualified serviceman check over the entire system at least once each
year as well as any other time that you feel that one is needed. Your
serviceman should examine and inspect:
•filters (for cleaning or replacement)
•motors and drive system components
•condenser coils (for cleaning)
•safety controls (for mechanical cleaning)
•electrical components and wiring (for possible replacement
and/or connection tightness)
•condensate drain (for cleaning)
In addition, your serviceman should inspect:
•unit duct connections to see that they are physically sound and sealed
to the unit casing
•unit mounting support to see that it is sound
•unit to see that there is no obvious unit deterioration.
