Putting into operation
4.1.3 Connect inert gas (only with inert gas connection)
WARNING
Danger of explosion and poisoning when introducing gases/materials
other than inert gas. Only inert gas (nitrogen, helium, neon, argon,
krypton) may be introduced into the appliance through the gas con-
nection on the rear of the appliance.
WARNING
Gas bottles may burst or explode at high temperatures. Keep the gas
bottles away from open
fl
ames. Do not store gas bottles at or above
50 °C and ensure that the location is always well-ventilated. Prevent
water from penetrating as well as back
fl
ow into the gas bottles. It is
essential that you read the safety notes and instructions of the gas
supplier.
CAUTION
When operating with inert gas, the device releases small quantities
of the gas used into the environment. Make sure that the room is
suf
fi
ciently ventilated.
Connect an inert gas cylinder (pressure reducer) with a connecting hose with DN16KF
connection to the connection on the rear of the unit (Fig. 18
2
). Set pressure reducer to
between 1.0 and 1.2 bar.
4.1.4 Fresh air supply
NOTICE
►
Compressed air must not be connected to the fresh air connection.
As a rule, no connecting hose is connected to the fresh air connection. If only clean air
may be introduced into the interior, the fresh air connection can be connected by the
customer to a tank with treated air.
4.2 Install
suction
The type of extraction must comply with the relevant national regulations on occupa-
tional safety and environmental protection.
Push a Norprene hose from the outside through the perforated back into the pump
stand. Open the door and connect the hose to the outlet (pressure side) of the pump
(outlet is hose nipple G1/4 for hose ID9).
