specific to connection, setup, maintenance and repair.
Fan maintenance and installation shall only be performed by professional
electricians qualified for unassisted operations with electrical installations
up to 1000 V after careful study of the present manual.
All the fans are not designed for out-of-the-box operation and require
connection to the air ducts.
The ducts are connected to the fan on both sides.
If the fan is mounted outdoors it should be protected against the elements
and moisture (e.g. by means of a top hood above the fan).
Prior to connecting the fan to the power mains check for visible damage
of the casing and any foreign objects in the fan casing which may damage
the impeller blades.
The fan may only be used as intended. No modifications or alterations
are allowed. The fan is not intended for operation in areas with an explosive
and/or chemically aggressive environment.
Take all the reasonable steps to prevent back draft of gas from any units
which utilize gas or direct flame.
The fan is rated for connection to single-phase ac 230 V / 50 Hz and
three-phase 380/50 Hz power mains.
Prior to the fan installation check the integrity of the power supply wires
and for any obstructions to the impeller wheel.
It is recommended that flexible inserts are mounted on both sides of the fan
upstream and downstream.
Mount the fan in such a way that the arrow on the fan casing matches the
air flow direction in the system.
The fan requires reliable grounding.
