Cooling and exhaust air
Unit cooling:
The air for cooling the tubes and burners in the ca-
nopy section is sucked in through the upper
fi
lter mat. Ambient
air for cooling the tubes in the base section is sucked in through
the front
fi
lter mat in the base section. The fan collects the coo-
ling air coming from above and below, which is then blown off
through the exhaust-air
fl
ue.
Body cooling:
A body fan blows ambient air (if not equipped with
air-conditioning unit), or chilled air (if equipped with air-conditio-
ning unit), into the tanning space of the system (blue). The air
spoiler at the canopy pane directs this air towards the face.
If the system is equipped with an air-conditioning unit (optionally
available), the base pane is also cooled.The ambient air is su-
cked in through the
fi
lter, chilled in the air-conditioning unit and
led through an air hose to the space between ducting pane and
base pane. At the foot end of the base section the air is blown
into the tanning space of the system.
Cooling of the
base pane
A clean exhaust air system in good working order prevents the
unit from overheating. The maximum length of the exhaust-air
hose of 6 metres must not be exceeded if there is no additional
fan.

tion 3.8
5
Check whether the exhaust-air hose is kinked or damaged;
furthermore, check the working order of the additional fan in
cases where the hose length exceeds 6 m.
6
Adequate ventilation and air extraction both in the studio
and in the tanning booth must be ensured at all times.
