Mounting the peripheral devices enclosed in the
delivery
This chapter describes interventions in the refrigeration
circuit. Refrigeration expertise is required for this work.
WARNING
The compressor is under pressure!
Serious injuries are possible.
Depressurize the compressor!
Wear safety goggles!
After mounting new components such as discharge gas
temperature sensor, pressure transmitter, injection
nozzle or injection valve:
WARNING
Serious injuries are possible. New component
may suddenly become detached.
Check the thread.
Carefully screw in the new component. Observe
the tightening torques!
Perform a tightness test before commissioning!
After assembly of all components:
!
!
NOTICE
Refrigerant or oil can escape after installation
work on the compressor.
Carry out a leak test before commissioning!
6.1
Assemble components for application limit
monitoring
High- and low-pressure transmitters B6 and B7 provide
the measurement data for application limit monitoring.
The components are supplied as an accessory if the
"Application limit monitoring" option has been ordered.
!
!
NOTICE
Incorrect measurement data leads to com-
pressor failure.
Do not interchange high- and low-pressure
transmitters. Check the stamped component
number exactly.
• High-pressure transmitter B6: 2CP5-71-47
• Low-pressure transmitter B7: 2CP5-71-49
Mounting position of the high-pressure transmitter
• Connect to the high-pressure connection of the com-
pressor with a refrigerant hose. Length of the refri-
gerant hose: 20 cm. Connection position see operat-
ing instructions, chapter Assembly, connections, po-
sition 1(HP) or see chapter Dimensional drawings,
page 10, position 2 If the high-pressure switch is
also to be mounted at this point, a T-piece is addi-
tionally required.
• Alternatively, connect directly to the liquid line dir-
ectly after the receiver.
Mounting position of the low pressure transmitter
Connect as close to the suction gas valve as possible
with a refrigerant hose. Select refrigerant hose at least
20 cm long so that the pressure transmitter does not
thaw.
6.2
Install additional fan (M2)
➙ If an additional fan has been ordered, the fan feet
are mounted on the cylinder heads when delivered.
• Unscrew the fan basket. See enclosed Technical In-
formation KT-140.
6.3
Installing the RI system
The RI system consists of
• 1 RI injection valve with electric connector of the
device and cable to CM-RC-01
• 1 RI injection nozzle for 4-cylinder compressors
2 RI-injection nozzles with connecting line for 6-cylin-
der compressors
• Operation via the CM-RC-01
The RI system can also be retrofitted.
Required tools
• open ring spanner
• torque spanner
Installing the RI system
• Remove plugs at the injection point(s). 1 plug for 4-
cylinder compressors and 2 plugs for 6-cylinder com-
pressors. For the position(s), see the operating in-
structions, chapter "Assembly", "Connections", item
4 (CIC).
• Install the RI injection nozzle(s). For the tightening
torque, see KW-100.
• Remove the union nut and sealing cap from all RI in-
jectors.
• For 4-cylinder compressors: Screw the RI injection
valve onto the RI injection nozzle. Orient the pipe in-
let in the opposite direction of the plenum box.
Tighten the screws at the end of the connecting line,
holding them against the RI injection nozzle.
