22.2 Cleaning
Regular cleaning prevents unbalance.
WARNING
Hazard from electrical voltage
›
Internal cleaning of the Multibox only by a trained electrician or trained and instructed qualified personnel.
›
Pay attention to the 5 rules of electrical engineering:
–
clear (all-pole separation of an electrical system from live parts)
–
secure against switching on again
–
establish freedom from voltage
–
earth and short-circuit
–
cover or fence off neighbouring live parts.
CARE
Danger from hot surfaces!
›
Wear protective gloves in maintenance and cleaning work!
"
Keep the air ducts of the Multibox clear and clean them with a cleaning brush if necessary.
"
Do not use a steel brush.
"
Under no circumstances should you use a high-pressure cleaner („steam sprayer“).
"
In cleaning, do not bend the fan blades.
"
Do not use any cleaning agents to clean the inside.
22.3 Maintenance, repairs
As ball bearings with „lifetime lubrication“ have been used, the Multibox is maintenance-free to a great extent. After the end of the
period of use for the grease (about 30,000 to 40,000 h in standard applications), replacement of the bearings is necessary.
With I motors, the capacity of the capacitor can drop in the course of time, the life expectation is about 30,000 h according to VDE
0560-8.
WARNING
Hazard from electrical voltage
Observe the following in all installation and maintenance work:
›
ventilator rotor must be stationary
›
the electrical circuit must have been interrupted and secured against being switched on again.
›
industrial safety directives must be complied with.
"
Pay attention to atypical running noises.
"
When changing the ball bearings, only use original replacement parts (special greasing) from the firm of Systemair.
"
For all other damage (e.g. damage to the coil), please get in touch with our Service Department, Defective Multiboxes must be
completely replaced. Repairs may only be done by the manufacturer on its premises. You will find the address of the back of these
operating instructions.
22.4 Replacement parts
When ordering replacement parts, please state the type designation of your Multibox. You can find it on the name plate.
