PERIODIC INSPECTIONS OF THE AIR CURTAIN
It is recommended to perform a periodic inspection of the status of the curtain after every 500 hours of operation, and
also before and after the heating season.
- inspection of pollution of the water exchanger
- inspection of the status of the fan (especially the functionality of the fan and bearings)
- leak test of the water exchanger and connections
- inspection of the curtain whether it is damaged in any way (especially fan basket)
- inspection of tightening of screw connections, especially consoles
- inspection of the status of the filter (which may be more frequent due to the installation conditions)
Cleaning procedure
1) Dismount the section of fans from
a casing of the unit
3) Clean the water exchanger (if the air curtain
has one)
4) Replace the fans back
2) Clean the fans on all sides carefully
9. MAINTENANCE
The main electrical power supply (for fan + heater) must be shut down during maintenance of the heating
unit. Before maintenance it is necessary to let the air curtain cool down! When handling the unit, it is neces-
sary to use protective gloves against injury by sharp edges!
The following procedure illustrates the cleaning of one section of fans.
Cleaning needs to be done on all the fans.
