12. MAINTENANCE
Access to the inside of the machine by all panels. These
access panels are fi xed with rivet nuts M4.
Centrifugal fan
- Verify that the turbine and the motor remain clean.
- Foresee having a spare belt set for the fans.
- The motors and the fans have bushings that have been lubricated
and sealed and, thus, do not need further lubrication.
The minimal maintenance operations and their periodicity will be made
according to the national regulations.
Any intervention on the electric cooling components must be made by
a qualifi ed and authorized technician.
Technicians who intervene with the unit must use the necessary safety
equipment (gloves, goggles, insulating clothing, safety shoes, etc.).
Furthermore, if working around sources of significant noise, we
recommend the use of noise-dampening headgear.
V-220004
Caution: Before intervening in the unit, cut off main power.
V-220005
Condensate drain pans
- Check that the condensate pans of the outdoor and indoor circuits
are clean. There should be no stagnant water.
- Check that the drain is not clogged.
- Cleaning of the pan can be done with water and non-abrasive
detergent.
Servomotor (optional)
In units with a condensation pressure regulation damper (in the STD
version), it is advisable to check the state of the servomotor.
Indoor circuit

Air fi lters
The frames with the gravimetric and opacimetric fi lter can be extracted
easily by both sides.
- Clean usually. Depending on the installation conditions, the fi lter
aspect must be examined to defi ne the cleaning periodicity.
- Gravimetric fi lters. Cleaning the fi ltering mesh can be done with a
household vacuum cleaner, or else by submerging it in water.
- Creased opacimetric fi lters It is necessary to replace them. Foresee
replacement.

General recommendations:
- Do not lean on the unit. A platform must be used to work on a level.
- Do not lean on the copper refrigerant tubes.
- Keep the unit clean.
- Keep the space surrounding the unit clean and cleared in order to
avoid accidents and ensure the proper ventilation of the coil.
- Perform a visual (remains of water or oil below or around the unit)
and auditory inspection of the entire installation.
- In general, a corrosion control must be performed on the metallic
parts of the unit (frame, bodywork, exchangers, electric panel, etc.).
- Check that the insulation foam is not unstuck or torn.
- All the electric connection states must be checked as well, as well
as the air tightness of the different circuits.
Next, some recommendations are stated to perform the cleaning of
the unit's components:
Air coil
- Check that the coil is free from dust and grease.
- Cleaning the accumulated dust on the coil can be performed with
a vacuum cleaner perpendicular to the fi ns or with a low-pressure
water cleaner. Grease can be removed with water with degreaser.
Do not put stress on the fi ns as they could deform.
Use safety gloves for this task. Take care with the sharp
parts of the coil.
