Installation

5.1

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.
The warm exhaust air should be led off from the unit and out of the premises,
fig. 3 position 8. Connect a duct that leads the exhaust air outdoors.
CAUTION! Risk of equipment damage.
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 m in front of the start and
control unit and in front of the dust collector. Otherwise a free space of about
0.5 m is recommended around the unit.
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.
WARNING! Risk of personal injury.
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.
