Installation
Site
The unit should be positioned indoors. If it is positioned
outdoors the area should be protected from the weather.
The ambient temperature must not exceed 40 °C
(104 °F).
The unit should stand flat and steady and be anchored
to the floor.
There are four fastening brackets on the
bottom frame to be used for fastening the
unit to the floor, see fig.8. The enclosed
frame shall be fastened in the back of the
unit after fastening the unit. If the unit is to
be moved the frame must be attached to
the front of the bottom frame. The collector
bin must be emptied before moving the
unit.
The warm exhaust air should be led off from the unit and
out of the premises, fig. 7 pos. 8. Connect a duct that
leads the exhaust air outdoors.
The air can be led to a heat exchanger,
but there must be no dampers that can
obstruct the air flow. If the exhaust air duct
is blocked the unit can create an
overpressure, which may cause major
damage to the heat exchanger.
For servicing, there must be a free space of 1.2 m in
front of the start and control unit and in front of the dust
collector. At the back of the unit a free space of about
0.8 m is recommended. 2.1 m space is recommended
when "tiltig" the filter holder and 1m above the filter to be
able to lift the filter. (1.5 m is recommended when using
of a "lifting device", see fig. 10)
If the unit is positioned in a small room, the room should
be fitted with two ventilation openings, minimum 250
x 250 mm (10" x 10"). One should be high up and the
other low down.
A small room must never be completely
sealed!
If there are no ventilation openings a
dangerous underpressure can be formed
resulting in serious personal injuries, even
the room can be damaged!
