POWERING THE UNIT
- Power up the unit by closing the isolator switch (if fitted).
- At this point the blower should start unless the climatic
does not energise the contactor. In this particular case the
blower can be forced by bridging the port NO7 and C7 on
connector J14 on the Climatic. Once the fan is running
check the rotation direction. Refer to the rotation arrow
located on the fan.
- The fans and compressors direction of rotation is checked
during the end of line test. They should therefore all turn in
either the right or wrong direction.
NOTE : A compressor rotating in the wrong direction will
fail.
- If the fan turns in the wrong direction, disconnect the main
power supply to the machine at the building's mains switch,
reverse two phases and repeat the above procedure.
- Close all circuit breakers and power up the unit, remove
the bridge on connector J14 if fitted.
- If now only one of the components rotates in the wrong
direction, disconnect the power supply at the machine's
isolator switch (if fitted) and reverse two of the component's
phases on the terminal within the electrical panel.
- Check the current drawn against the rated values, in
particular on the supply fan (ref. page 34).
- If the readings on the fan are outside the specified limits,
this usually indicates excessive air flow which will affect the
life expectancy and the thermodynamic performances of the
unit. This will also increase the risks of water ingress into
the unit. Refer to the "Air Flow Balancing" section to correct
the problem.
At this point attach the manometers to the refrigerant circuit.
RUN TEST
Start unit in cooling mode
Thermodynamic readings using manometers and
prevailing environmental conditions
No rated values are given here. These depend on the
climatic conditions both outside and inside the building
during operation. However, an experienced refrigeration
engineer will be able to detect any abnormal machine
operation.
Safety test
- "Dirty filter" detection test : vary the set-point value
(menu
3413 on DS50)
in respect to the air pressure value. Ob-
serve the response of the CLIMATIC™.
- Same procedure for detecting "Missing Filter"
(menu
3412)
or "Air Flow Detection"
( menu 3411)
.
- Check the smoke detection function (if fitted).
- Check the Firestat by pressing the test button(if fitted).
- Disconnect the circuit breakers of the capacitor fans and
check the high pressure cut-out points on different
refrigerant circuits.
Reverse cycle test
This test is designed to check the good operation of the 4-
way reversing valves on heat pump reversible systems.
Start the reverse cycle by adjusting the cold or hot
temperature threshold data according to the indoor and
outdoor conditions at the time of test
(menu 3320).
