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
- Check Air pressure switch (if fitted) "Dirty filter" detection
test: vary the set-point value (menu page 3413 on DS50) in
respect to the air pressure value. Observe the response of
the CLIMATIC™.
- Same procedure for detecting "Missing Filter" (page menu
3412) or "Air Flow Detection" (page menu 3411).
- Check the smoke detection function (if fitted).
- Check the Firestart 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).
