Guarding
NOTICE
The fan must be guarded according to local regulations
INS00025-A Original instructions
Illustration 16: Optionally available guard
Default, the fan is delivered with a guard on the intake side. The shutter acts
as a guard for the exhaust side, but does not provide the required safety
distances to prevent hazard zones being reached by upper and lower limbs
(ISO 13857:2008). Depending on installation height or location, the shutter
may therefore not provide the required level of protection. A guard for in
between the shutter and fan housing is optionally available. Please contact
your supplier for more information.
Condensate drain holes
The fan motor has drain holes to allow condensation that may form inside the
motor to leave the motor. After installation, the drain hole at the lowest point
of the motor must be open, the other drain holes must be closed.
Spare condensate drain plugs are supplied with the fan. Keep all the drain
plugs as they must be temporarily reinserted in the open drain holes during
wet cleaning.
