Installation instructions
•
Prior to installation, ensure that the O-ring at the connecting flange is
seated properly.
•
There must be no foreign objects in the oil infeed or outfeed area of
the INT280-60.
•
The device has to be mounted to the compressor horizontally. It can
be rotated by 180°.
•
Use matching washers for the flange fastening screws.
•
Oil level regulator is pre-assembled in installation position.
•
Manually screw in the screws.
•
Afterwards tighten the screws alternating with a torque of 9Nm (M6,
steel 8.8, dry).
•
The electrical connection needs to be carried out according to the
wiring diagram.
•
For use at low temperatures, an oil sump heater has to be installed,
to ensure trouble-free operation of the INT280-60.
•
An oil filter has to be installed in the oil infeed line of the INT280-60,
to prevent the solenoid valve seat from getting dirty.
•
Before the refrigerating system is filled with refrigerant, the system
and the connections of the INT280-60 have to be checked for leaks.
The mounting, maintenance and operation are to be carried out
by an electrician. The valid European and national standards for
connecting electrical equipment and cooling installations have to
be observed.
Connection lines that extend from the terminal box have to
feature at least a basic insulation.
The user has to ensure that the connections are properly tight.
The electrical connection needs to be carried out according to
the wiring diagram.
Prior to installation, ensure that the pressure in the refrigeration
circuit is and stays equal to the atmospheric pressure.
The voltage supply to the INT280-60 must be switched off prior
to installation/connection and the subsequent tasks.
Flash code
The KRIWAN flash code allows for a quick and easy status display and
troubleshooting.
The flash code consists of a cyclical flash sequence (red / orange or
green / orange). The current status can be determined from the number
of pulsing flashes.
