19.2 Cleaning the fins of the condenser
Dust on the fins of the condenser reduces the cooling capacity. Therefore, it is necessary to clean the
fins frequently. The following steps are recommended:
• Shut off the gas flow;
•
Disconnect the power supply.
• Disconnect the tubing for gas in- and outlet;
• Unscrew the cooler hood and remove it carefully;
• Clean the fins carefully with compressed air;
•
Re-install the cooler hood;
•
Connect the tubing for gas in- and outlet.
Note
Do not mix up the tubing connections; the inlet and outlet connections of the
heat exchangers are marked with arrows.
19.3 Maintenance of the optional mounted peristaltic pump(s), type SR25.2
Before starting any maintenance work, please make sure that any work done on the device is in
compliance with all relevant regulations and standards.
Danger
Dangerous voltage!
Disconnect power supply before carrying out any type of maintenance work.
Flexible tube, conveying belt, contact pulleys and contact springs are the only parts of the pump subject
to wear.
They can easily be replaced.
19.3.1 Mounting instructions for SR25.2 peristaltic pump (optional)
Make sure to mount the peristaltic pump SR25.2 to a front plate with a minimum thickness of 3.5 mm
[0.138”]. If the front plate is thinner than 3.5 mm [0.138”], use shims to adjust spacing. The maximum
thickness of the front plate is 5.5 mm [0.216”].
The minimum distance avoids damages to the pump motor, and the maximum distance prevents the
motor shaft from losing the guide inside the pump head.
