44.
Check the lateral casing walls and clean or disinfect them as
described above.
45.
This position enables a better accessibility to the inside of the heat
exchanger and therefore an easier cleaning. Clean the heat exchanger
with a vacuum cleaner from the inside. Use proper nozzle attachments for
the vacuum cleaner (e.g. Numatic angle-rubber nozzle with brush 601179).
Avoid bending the fins of the heat exchanger by vacuum cleaning carefully
in direction of the fins. Disinfect the interstices of the fins via spray disinfec-
tion. After exposure time, remove any disinfectant residue as completely as
possible, e.g. by spraying with clear water. Make sure to collect any drip-
ping liquid (e.g. by covering the floor).
46.
Remove the provisional cable strain relief.
Re-mount the fan by once
again using the 4 nuts crosswise. If you have any difficulties matching the
fan plate to the 4 bolts, fix the impeller to the plate with a cable strap. Make
sure the cable strap nose can easily be reached to remove the cable strap
with no difficulties later on.
RISK OF PERSONAL INJURY!
Take care not to injure yourself on the sharp cutting edges of
heat exchanger fins.
RISK OF DAMAGE TO THE UNIT!
Tighten the screws hand-tight only (max torque 2.5 Nm)!
