GENERAL STATEMENT
Cooline CDL series is designed and built for the optimum performance when matched with the right indoor unit (Refer to
indoor unit catalog). However, it is required that you become well acquainted with good practices for the proper installa-
tion, operation, and maintenance procedures in order to ensure a safe trouble free operation, year after year.
Most of the procedures described in this manual require certain skills and experience. Only highly skilled and experi-
enced technicians should perform the installation and other maintenance procedures.
SAFETY ISSUES
There are three levels of safety hazards that are identified throughout this manual as Warning (where the situation will
result in personal injury), Caution (where personal injury might occur), and Attention (where minor personal injury and/or
property damage could happen). Please understand and respect those identifications.
WARNING: These units operate on a high voltage with moving parts (at high speed) which can lead to
serious injuries and/or damage to the unit. Never attempt to service the unit unless the main electrical power
supply has been disconnected.
CAUTION: Extra care should be observed when installing, test running, adjusting, servicing, or maintaining
the unit as the hazard of explosion, fire, electrical shock, and potential personal injury and property damage
are present.
Whenperforming anytask pertainingto the installation andmaintenance of the unit, the skilled technician should observe
all the applicable safety measures (wear of safety helmet, boots, and goggles. Use of proper handling materials for
brazing and use of wet cloth for sequencing. A fire extinguisher should be easily accessible etc). He should also read all
the instructions and information in this manual prior to attempting to perform any installation or servicing of the unit.
All applicable local codes should be observed during installation and servicing.

NOTES
1. ANY WIRE REPLACEMENT SHOULD BE OF 900C
OR ITS EQUIVALENT.
2. USE COPPER CONDUCTOR WIRES ONLY.
3. POWER MUST BE SUPPLIED TO CRANKCASE
HEATER FOR MINIMUM OF 12 HOURS PRIOR TO
SYSTEM START UP.
IF POWER IS OFF 6 HOURS OR MORE, CRANK-
CASE HEATER MUST BE ON FOR 12 HOURS BE-
FORE OPERATING THE SYSTEM.
FAILURE TO FOLLOW THESE INSTRUCTIONS
MAY RESULT IN COMPRESSOR DAMAGE.

CONTROLS AND SEQUENCE OF OPERATION
The unit is equipped with an electronic control board which can be linked with any commercially available 24V ac thermo-
stat or can be controlled through a DDC panel. With cooling input signals coming from a thermostat or DDC, the motors
in the equipment are started in the following sequential order: condenser fan – compressor motor. The cooling input
signals to the unit’s control board should always start first with the first stage (Y1) followed by the second stage (Y2) and
“OFF” sequence should start with the second stage (Y2) followed by the first stage (Y1).
Balance Loading of Compressors: The user can select the sequence of operation of the compressors; either com-
pressor 1 as always leading (dip switch #2 set at ON) or enabling balance loading of compressor (dip switch #2 set at
OFF). In balance loading function, the compressor with the least run time will be started first to equalize the run time of
the compressors. These functions are selectable through the dip switch on the electronic control board. Please refer to
the settings table shown in the unit’s wiring diagram.
Fault Diagnostics: In case of system fault, LED’s on the board emits a flashing signal indicating the nature or where the
fault is. This is to guide the service technician in identifying the fault. Please refer to the settings table shown in the unit’s
wiring diagram for the details of each respective fault against LED indicators.
Compressor Lock-Out Function: If any of the unit’s safety control devices trips and such condition is maintained for
approximately 3 minutes, the control will lock-out that particular system preventing a re-start. It can be re-set by shutting
off power to the thermostat or if the cooling signal to the board is turned OFF.
Compressor Anti-Recycling Timer: The unit’s electronic control board has a built-in three (3) minutes minimum off
timer for the compressor. This is for compressor protection in case of accidental manual re-set or immediate re-cycling
through the thermostat due to load demand.

LIFT
ATTENTION TO RIGGERS
Hook rigging sling thru holes in base rail, as shown below.
Holes in base rail are centered around the unit center of gravity.
Center of gravity is not unit center line.
Ensure center of gravity aligns with the main lifting point before lifting.
Use spreader bar when rigging, to prevent the slings from damaging the unit.
CAUTION
All panels should be in place when rigging.
Care must be taken to avoid damage to the coils during handling.
Insert packing material between coils & slings as necessary.
