Maintenance

Danger!
Prior to carring out cleaning on the machine switch off the machine via the mains
isolator (36) and disconnect it from the mains.
There are few user-serviceable parts inside the unit. Other than the items listed below,
maintenance should be carried out by Huber-trained and authorised personnel.
Cleaning cooling fins (for air cooled machines with compressors only)
To ensure that the temperature control unit will give the maximum cooling power the
unit has to be freed from dirt (dust) from time to time. Please provide for an
unrestricted air supply (discharge from heat loss, fresh air supply). Keep a distance of
20cm to walls for air cooled units. Identify the position of the air outlet, normally it is to
be found at the front, with some other units it can also be found on the side, the rear or
under the temperature control unit. Remove the air outlet grill to gain access to the
cooling fins. With the help of a brush or vacuum cleaner, you can clean the fins of the
black condenser at the back of the cabinet. However, never use pointed objects.
Please see that the condenser fins are not damaged or deformed, as this may impair the
air current.
Cleaning the water filter (for water cooled machines with compressors only)
Depending on water quality, the filter at the cooling water inlet has to be cleaned
regularly. Immediately after the cooling water connection there is the cooling water
filter. Close the water supply lines and place a container below the cooling water outlet.
Use a 17mm spanner (wrench) to remove the filter cover. The metal cooling water filter
is underneath the cover, and can be removed and rinsed.
We are pleased to offer service training for users. Please contact Customer Support
