OPERATION
INDOOR FAN TRANSMISSION ADJUSTMENT
Adjust transmission in such a way that the indoor motor consumption comes to its normal value.
If consumption is below nominal value it means that unit air flow is too low.
To change fan speed:
1. Remove the belt. Move the motor along its track (or loosen the tensor set screw) in order to release it.
2. Loose the set screws of the motor pulley and turn the movable flange. Open of close depending on the needs
(Open: speed decreases).
3. Tighten set screws.
4. Place the belt in the pulley cannel. The closure of opening of the pulley could void the size of the prior belt. In
this case, replace it for other belt of the same profile and with the appropriate length.
5. Tighten the belt by using tensor screw or sliding the motor, depending on the case.
-Align fan and motor pulleys:
1. Loose fan pulley set screws.
2. Slide fan pulley along the shaft and align with motor by using a ruler in order to ensure that is parallel to the belt.

MAINTENANCE
It is advisable to do maintenance works every 1.000 operating hours as well as at the beginning of each cooling season.
In case of leakage, any manipulation and / or recovery of refrigerant must be carried out by qualified and accredited
personnel in the current regulations.
CONSERVATION AND CLEANING
Electrical circuit: Make sure that all electrical connections -wires, contactors and terminals- are properly tight. Record the
readings for volts and amperes of each compressor and fan motor. Verify the starting current. Check the good operation
of all relays, pressure switches and phase sequence relay of Scroll compressor.
Coils: At least once a year, clean condenser coils with water and detergent, then dry with air at a low pressure. Never
clean with wire brush.
Fans: Check the direction of rotation of the fans. Examine the support of the fans. Check the operating status.
Before handling the fan, make sure that it is disconnected from the main power, even if it is already stopped and that
nobody can start it during the intervention.
- It is necessary to make a regular inspection of the unit. Its frequency must be based on the working conditions to avoid
the accumulation of dirt in propellers, turbines, motors and grids that could entail risks and shorten its life.
- Be very careful not to unbalance the propeller or the turbine in cleaning operations.
- Must observe the current safety legislations of each country in all maintenance and repairing works.
Motors and fans do not need any additional lubrication.
Transmission belts: Check the status and the tension of the transmission belt, at least twice the first operating month,
after every 1000 operating hours.
Drainage system: Verify condition and good operation of the drainage tray and the drain trap.
Air filters: Clean filters after the first operating hours to collect possible light materials such as papers, pieces of porexpan,
etc. left over from the installation and that have been dragged through the air circulation. Clean again every 3 months (or
more often according to its operation). The filter can be cleaned with soapy water, after rinse it with clean water and let
dry. If necessary, replace filters before they are in bad conditions (check current legislation of each country, EN 779, UNE-
EN 13053…).
Before performing any service or maintenance operation it is mandatory to turn off the main
power switch of the system to avoid any personal injuries. Locked it so that nobody other
than a qualified technician can switch on electrical power
