1.15.1 Planned Maintenance Schedule
The following table shows the recommended frequency for regular maintenance tasks. Depending on
the environmental and working conditions where the unit is installed, maintenance tasks may be carried
out more or less frequently. The units must undergo all planned maintenance, without exception.
The person responsible for the building or property where the unit is installed must ensure that these
inspections are performed at the appropriate time. Likewise, this person should keep and maintain a log

1.15.2 Maintenance tasks performed by specialised personnel
D A N G E R
• The unit has a remote control, which means that the fan turbine may start unexpectedly.
• Disconnect the general switch on the unit before removing any of its side panels.
Indoor fan
All AR ‑ 100 / 175 units incorporate single speed motors with belt transmission for indoor ventilation.
In the unit start-up, the fan motor variable diameter pulley can be regulated in order to obtain the supply
air flow desired.
Adjusting the motor pulley and tensioning the belts
Check the condition of the belts and that they are correctly tensioned.
If necessary, replace them with a belt of the same type and measurements as the original.
1. Pulley opening adjustment:
a. Loosen the belts by turning the tensor screw -1-.
b. Loosen the set bolts -2- to release the mobile rims -3-.
A T T E N T I O N
Both grooves must have the same separation distance (same number of open turns).
c. Turn both the mobile rims on the thread of the fixed core of the pulley, in the appropriate direction
to increase or decrease the pulley opening.
d. Fully tighten the set bolts, checking that they match up to their housing in the fixed core of the
pulley.
