OPERATION
START-UP
Make sure you have access to measuring instruments with their up-to-date calibration certificates.
Thermometer, anemometer, voltmeter, hook-on meter, high and low manometer.
The person/people who will complete the measuring operations or the ones who will participate in the start-up
process must be qualified professionals with the valid certification according to the local regulation.
Please read all the security precaution guidelines.
Before using a hook-on meter make sure that the cable or the cables are connected properly. To disconnect a cable
by using force may damage the equipment and entail people injuries.
It is necessary to register the air inlet and outlet temperatures to the internal coil, the volts and amps of the
compressor and motor fan, as well as the suction and discharge pressure of each compressor.
Remember that it is necessary to clean the air filters after the first 4 hours of operation.
Complete at least 3 cooling cycle operations.
Indoor fan start-up:
-
Do not approach the fan while it is rotating even at a very slow rotation speed!
-
Beware automatic restart!
The fan / motor may start and stop automatically for functional reasons.
After a power cut or a technical failure the fan will restart as soon as voltage is present again!
-
ROTATION CAUSED BY AIR FLOW IN THE WRONG DIRECTION.
If you switch the fan on while it is rotating in the opposite direction the control will reduce the rotations until it
reaches the ‘0’ value (fan stoppage). Then, the control will make a restart in the correct rotation direction.
The higher the number of rotations in the wrong direction, the longer time the control will need to make the fan
stop. If the fan is rotating heavily in the wrong direction the control may not be able to start the fan in the correct
direction.
Do not switch the fan off and restart it again to slow it down!
