SAFETY CONSIDERATIONS
INSPECTION
Installation and s ervicing of air conditioning equipment can
be hazardous due to system pressure and electrical
components. Only trained and qualified service personnel
should install, repair or service air conditioning equipment.
Observe precautions in the literature, tags and labels
attached to the unit and other safety codes. Wear safety
glasses and gloves. Use quenching cloth and have fire
extinguisher available for all brazing operations.
Check the shipment against shipping list and remove unit
from the carton and take off protective covering. If the unit
has been damaged, file claim with Transportation Company
and notify Carrier immediately.
RECEIVING
38ASB/CCARS240~600 condensing units (Fig. 1) are
shipped individually packed in carton boxes. When cartons
are individually off loaded from truck, do not roll, nor throw,
or drop the carton, to avoid damages to the content. Store
boxes upright as the symbols or the boxes indicate. Do not
stack units more than 2 high.
PROTECTION
Protect unit from damage caused by job site debris. Do
not allow dust, debris and water get into the unit.
These will damage unit’s component and unit’s
performance will be affected.
WARNING
Before installing or servicing system always turn off main
power supply. There may be more than one disconnect
switch. Electrical shock can cause personal injury.

INSTALLATION
SELECTION OF MOUNTING POSITION
1)
2)
3)
4)
5)
6)
7)
The unit should be installed outdoors.
A place where air will not be stagnant.
A place where the exhausted air will not be sucked in for
the second time.
Allow sufficient space for airflow clearance, wiring,
refrigerant piping and servicing unit. See Fig. 2.
Avoid positioning unit in such a manner that water will
pour directly onto the unit.
Do not install the unit near a source of heat, steam or
flammable gas.
Ducting of the fan inlet or discharge is not permitted.
UNIT MOUNTING
1)
MOUNTING ON GROUND – Mount on a solid, level
concrete base. If conditions or local building codes
require unit to be fastened to base, tie down bolts
should be used and fastened through slots provided in
unit’s mounting feet (Fig. 3). Do not install unit directly
on ground.
2)
MOUNTING ON AND AGAINST THE WALL – the
bracket is to be locally procured (Fig. 4).
3)
MOUNTING ON ROOF – Mount on a level platform or
frame. When multiple unit are installed, the air outlet
side should be opened as shown in Fig. 5.
When installation base is used, secure the required spacing
as per (Fig. 6). Fabricate the stand so that it will have
sufficient strength.
Run refrigerant tubes as directly as possible, avoiding
unnecessary turns and bends. Condensing unit may be
connected to evaporator sections using field-supplied
tubing of refrigerant grade, correct size and condition.
Suspend refrigerant tubes so they do not transmit
vibration to structure. Also when passing refrigerant
tubes through walls, seal opening so vibration is not
transmitted to structure. Leave some slack in refrigerant
tubes between structure and unit to absorb vibration.
The longer the piping, the lower the cooling capacity of
the unit. See table 3.

FIG. 6 MINIMUM SPACING REQUIREMENT
REFRIGERANT PIPING
Size Refrigerant Lines. Consider length of piping required
between unit and evaporator, amount of liquid lift and
compressor oil return (Table 4).
Do not bury section of line set underground. If any section is buried,
refrigerant may migrate to cooled buried section during extended period of
unit shutdown. This causes refrigerant slugging and possible compressor
damage at start-up.
If either refrigerant tubing or indoor coil is exposed to atmospheric
conditions for longer than 5 minutes, it must be evacuated to 1000 microns
to eliminate contamination and moisture in the system.
4
PIPING CONNECTIONS
Complete all installation and piping work required for indoor and
outdoor units. If brazing is required pass nitrogen or other inert gas
through piping to prevent formation of cooper oxide. Unit contains R22 charge, do not open Schreader valve at this time. Leak test field
piping by pressure method.
Note: - Operation of unit on improper line voltage constitutes
abuse and could affect Carrier Warranty. Do not install
unit in system where voltage may fluctuate above or below
permissible limits.
START-UP
PRELIMINARY CHECKS:
1)
Check that all internal wiring connections are tight and all
barriers, covers and panels are in place.
Field electrical power source must agree with unit name
plate rating.
All service valves must be opened.
PIPING INSULATION
No refrigerant control device is shipped with the unit except 024
model. It is already installed in matching Fan coil units, check
carefully the indoor unit. Insulate suction line adequately (Fig. 8)
2)
3)
START SYTEM
NOTE: Model 240 need
to insulate both Suction
and liquid pipes
1.
2.
Check that field disconnect is closed.
Set room thermostat to below room temperature, and unit
compressor will start after 3 minutes delay o.
Check back pressure when compressor runs. Add charge to
keep back pressure at approximately 448kPa (65 PSIG).
3.
REFRIGERANT CHARGING
CAUTION
TO PREVENT PERSONAL INJURY, WEAR SAFETY
GLASSES AND GLOVES WHEN HANDLING
REFRIGERANT. DO NOT OVERCHARGED SYSTEM.
THIS CAN CAUSE COMPRESSOR FLOODING.
FIG. 8 PIPING INSULATION
COMPLETE ELECTRICAL CONNECTIONS
CAUTION
THE CONTROL VOLTAGE FROM THE FAN COIL UNIT
MUST BE OF 230V. DO NOT CONNECT THE POWER
SUPPLY TO THE SIGNAL
POWER – Unit is factory wired for voltage shown on name plate.
Provide adequate fused disconnect switch within sign of unit, readily
accessible, but out of reach children.
Provide for locking switch open (OFF) is advisable to prevent power
from being turned on w hile unit is being serviced.
Route power wires through opening in unit side panel and connect in
unit control box (fig. 9). Unit must be grounded.
IMPORTANT
For accurate system performance, charge by superheat method
as shown in table 5 and 6.
To check and adjust charge, follow the following procedures:1)
2)
3)
4)
5)
6)
7)
Operate unit for a minimum of 15 minutes before checking
charge.
Measure suction pressure by attaching a gauge to suction
line service port.
Measure suction line temperature by attaching a service
thermometer to unit suction line near suction valve.
Insulate thermometer for accurate readings.
Measure outdoor coil air inlet dry-bulb temperature with a
second thermometer.
Measure indoor coil air inlet wet-bulb temperature with a
sling psychrometer.
Refer to table 5. Find air temperature entering outdoor coil
& wet-bulb temperature entering indoor coil. At this
intersection, note the superheat.
Refer to table 6 . Find superheat temperature and suction
pressure, note suction line temperature.

CONTROL CIRCUIT WIRING
Refer to wiring diagram for field supplied wiring details.

REFRIGERANT CHARGING (cont)
8)
If unit has higher suction line temperature than charted
temperature add refrigerant until charted temperature is
reached.
9) If unit has lower suction line temperature than charted
temperature, bleed refrigerant until charted temperature is
reached.
10) If air temperature entering outdoor coil or pressure at
suction line charge to new suction line temperature
indicated on chart.
11) This procedure is valid independent of indoor air quantity.
SERVICE AND MAINTENACE
CAUTION
BEFORE PERFORMING RECOMMENDED MAINTENANCE
AND SERVICE, BE SURE UNIT MAIN POWER SWITCH IS
TURNED OFF. FAILURE TO DO SO MAY RESULT IN
ELECTRIC SHOCK OR INJURY FROM ROTATING FAN
BLADE.
FIG. 10 CLEANING COIL WITH WATER
LUBRICATION
Fan motor is permanently sealed lubricated bearings. Do not oil.
Compressor is supplied charged with oil. Replace oil when lost.
See table 2 for oil recharge quantity.
CLEANING COIL – Coil should be washed out with water or blow
out with compressed air. The draw thru design causes dirt and
debris to built up on the outside of the coils. Clean coil as follows:1)
2)
Turn off unit power.
Using a water hose or other suitable equipment, flush coil from
the inside to remove dirt (see Fig. 10). Be sure to flush all dirt
and debris from drain holes in base of unit. Fan motor is water
proof but it is more safe to cover or wrap motor shell with
plastic sheet (or plastic bag) to prevent water from getting
inside.
Clean coil semi-annually or as required. Fins are not continuous
through coil sections. Dirt and debris may pass between the row of
fins and become trapped between the row of fins and restrict
condenser air flow. Use a flashlight to determine if dirt or debris has
collected between coil section.
