SAFETY CONSIDERATIONS
INSPECTION
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 units component and units
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.

Note: 1) Values shown are for units operating at 7.2 C saturated suction
0
and 35 C entering air.
2) Values in ( ) indicate a case when the outdoor unit is located at
a lower height than the indoor unit.
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.
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

REFRIGERANT CHARGING
CAUTION
TO PREVENT PERSONAL INJURY, WEAR SAFETY
GLASSES AND GLOVES WHEN HANDLING
REFRIGERANT. DO NOT OVERCHARGED SYSTEM.
THIS CAN CAUSE COMPRESSOR FLOODING.
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)
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.
