Installation and connections
General
Carefully remove the packing from the dryer.
Placing the dryer
It is best to move the dryer by means of a palett truck.
The dryer must be
leveled
.
It is advisable to leave a space of minimum 60 cm open behind the dryer for service-
and maintenance-purposes.
The walls, through which the exhaustpipe leads outside, should be made of
incom-
bustible material.
The dryer should get sufficient air supply (750 -DTI10 & DTI12 , 1050- DTI14
m
3
/h). If necessary, ventilation grates should be placed in the doors and windows.
Unsufficient supply of fresh air
can cause overheat problems. Moreover,
gas heated dryers can have ignition problems and this may result in an
increasing energy consumption.
Exhaust
The exhaust can be ordered at the back or on top of the dryer.
The exhaust pipes B22 needs to be made of heat-resistant material (150°C) and should
have a minimum diameter of 150 mm.
In order to ensure a good conduction of the vapours, this pipe should be kept
as short
as possible with a minimum of bends.
If the exhaust pipe comes into a main pipe, then the angle may be maximum 45°.
After the coupling of both pipes, the diameter of the main duct should be adapted.
The diameter of this duct should at least be the sum of the 2 coupled ducts.
The radius of the bends should preferably mesure
1,5 times the diameter of the ex-
haust pipe.
In order to protect the tail end of the exhaust pipe against severe weather conditions,
it may be bent down. Leave at least a free exhaust opening, which is
twice
as big as
the diameter of the exhaust pipe.
Avoid to use a cap on the tail end of the exhaust pipe. It is best to leave it free.
If the exhaust duct doesn’t comply with the above mentionned requirements, then a
series fan should be installed further down the pipe.
Ignoring these installation instructions can lead to a counterpressure
in the exhaust duct. This will make the heating function imperfectly
and will consequently result in a poor drying quality and an increasing
energy consumption.
