The gaseous refrigerant is compressed by cooling compressors M1 and M2 and from there flows to condenser
COND, where it is cooled by the extract air and is condensed to liquid form.
The gaseous refrigerant flows through expansion valve
VET1 and VET2, where the pressure and the temperature
decrease.
From the expansion valves, the refrigerant advances to
evaporator EVAP, where the refrigerant evaporates and
cools down the outdoor air.
The evaporated refrigerant flows from evaporator EVAP
further to the suction side by the compressors to once
again be compressed.
Regulation
The cooling capacity is regulated in three binary steps by
having one or two compressors in operation.
COOL DX is controlled via a signal, 0 – 10 V.
Step 1: When cooling is needed, Compressor M1 is started.
Step 2: If more cooling is needed, Compressor M2 starts
and at the same time Compressor M1 stops. An adjustable time delay (a step duration of 250 seconds) ensures
that Compressor M2 will not start until Compressor M1 is
operating at full capacity.
Step 3: If even more cooling is needed, Compressor M1 is
restarted and is run at the same time as Compressor M2.
This third cooling step is also delayed by a preset time delay setting. In addition, the restarting time (300 seconds)
for Compressor M1 shall have expired.
If less cooling is needed and the compressors are subsequently switched out step-by-step, there will be no delay
between compressors. The restarting time (300 seconds)
for Compressor M1 shall have expired to enable it to start
again in Step 1 after it has been operated in Step 3.
If any compressor is stopped, the restarting time must
expire before a restart can take place. The restart time is
calculated from one start to the next start.
If the pressure in the cooling circuit becomes too low, or
if the pressure in the condenser circuit becomes too high,
the compressor is stopped.
When the restart time has expired, the compressors will try
to restart.
Function
There are two refrigerant circuits in the chiller. The circuits
are separated from one another.
Each circuit is equipped with its own finned condenser,
finned evaporator and compressor.
The two compressors are of different capacity, which
makes it possible to regulate the capacity in 3 steps.
4 www.swegon.com
If the pressure increases more, high pressure switches BP12 and BP2-2 will trip and stop the chiller.
Alarms are shown on the hand-held terminal, see separate
instructions for IC208CX control.
Pressure switches BP1-2 and BP2-2 can be manually reset
by pressing a button under each protective sock on the
upper side of the pressure switch. This can be done without removing the protective sock.

5 COMMISSIONING
5.1 Preparations
5.1.1 Before initial start up
• The power supply should be connected.
• Terminals 105 and 106 in COOL DX electrical cabi-
net must be connected (closed switch), otherwise
the cooling machine will not start despite the signal
0 – 10 V, and no compressors are activated. (These
terminals can be used to connect an external thermostat to activate/deactivate signal 0 – 10 V for a specific
temperature).
• Terminals 103 and 104 shall be connected to give a
signal, 0-10 V.
A free contact for a general alarm is located on terminals
100, 101 and 102.
5.1.2 Control functions
Silver Cool DX is equipped with two controls:
• IC208CX Dixell, hardware version 7.3 or 4.2
• Siemens (model: 12/24 RC 6ED1052-1MD08-0BA0)
Signal 0-10 V is received by the Siemens control which
converts it to digital output signals (see below) and forwards these to control IC208CX.
Control IC208CX is set at the factory to moto-condenser
mode and starts or stops the compressors via the digital
output signals from the Siemens control. All control and
safety functions for the refrigerant circuit are regulated by
control IC208CX.
For conversion of the signal, 0 – 10 V to digital output
signals, see below.
5.1.3 Pressure sensor
The chiller has two in-service pressure switches in each
cooling circuit, one for low pressure and one for high pressure.
If the operating pressure, in any of the circuits, exceeds
or drops below a limit value, the relevant compressor is
switched off. See separate instructions for IC208CX control for further information.
The compressor is permitted to restart when the restart
delay has expired.
Pressure sensor settings:

cleaning and wiping surfaces with a damp cloth.
Inspections should be performed twice a year.
7.2 Handling of refrigerant
The refrigerant used is R 410A.
The refrigerant circuit is completely charged when the unit
is delivered.
Warning
Under no circumstances may the refrigerant circuit be
opened by unauthorised personnel, since it contains
gas under high pressure. Only an accredited refrigeration company shall be permitted to modify or repair the
refrigeration circuit.
The COOL DX is equipped with a safety valve to prevent
excessively high pressure in the system caused by e.g. a
fire.
Important:
Contact Swegon Service in the event of leakage of

Incorrect phase sequence.
The compressor safety circuit has been broken.
Defective compressor.
Too low cooling capacity The voltage has been isolated.
Incorrect phase sequence.
No air flow or too low air flow across the evaporator.
Thermostat/control equipment incorrectly set or defective.
The compressor switches off

Check the air flow.
GB.COOLDX.SI.G.190603
8.2 Leakage Tracing
Leakage tracing should be carried out at least once per
year as a precaution. The leakage tracing inspection must
be documented.
If the cooling system is leaking, this will become apparent
firstly by impaired cooling performance, or if the leakage is
substantial, when the chiller does not operate at all.
If you suspect that the cooling system is leaking refrigerant, check the level of refrigerant in the sight glass located
on the liquid line of the chiller.
If you see continuous and a substantial amount of bubbling in the sight glass and the chiller operates at appreciably lower capacity than normal, the system is probably
leaking. One or several bubbles appearing when the chiller
is started up, operation at reduced capacity or normal
operation need not necessarily indicate a refrigerant deficiency.
If it is bubbling in the sight glass and the chiller operates at
appreciably lower capacity, call for qualified service help.
NOTE! Maintenance work in the refrigerant system is permitted to be carried out only by an accredited inspectorate
(a company with requisite authorisation).
