Installation
CAUTION
Please observe the following to ensure that the unit

– Dropping the device can cause permanent dam-
age. In this event, replace the entire device and
associated modules before use.
– Avoid formation of condensation in the device.
– Do not store or install the unit in the open air.
– Check max. inlet pressure.
– Use a suitable spanner. Do not use the device
as a lever. Risk of external leakage.
▷
Installation in the vertical or horizontal position,
housing cover/indicators must not point upwards
or downwards. The electrical connection should
preferably be pointing downwards or towards
the outlet.
▷
The device must not be in contact with masonry.
Minimum clearance 20 mm (0.78").
▷
Use the O-rings supplied.
▷
In the case of very large test volumes V
P
, an
installed relief line should be of nominal size 40
to allow for the discharge of the test volume V
P
.
Disconnect the system from the electrical power
supply.
Shut off the gas supply.

Mounting TC V to valVario controls
▷
The solenoid actuator cannot be rotated on so-
lenoid valves with proof of closure switch VCx..S
or VCx..G.
▷
Connect the TC to the inlet pressure connec-
tion p
u
and the interspace pressure connection
p
z
of the inlet valve. Ensure that connections p
u
and p
z
on the TC and the gas solenoid valve
are not reversed.
▷
TC and bypass/pilot gas valve cannot be fitted
together on the same side of the double block
valve.
▷
When using a valve/pressure regulator combi-
nation VCG/VCV/VCH, the pressure regulator
must be activated with air during the entire test
period t

.
▷
The TC is secured using two captive combination
Torx screws T20 (M4) inside the housing. Do not
undo any other screws!
