The valve must be connected to the ground.
In the case most simple this can be realized via pipe screws by means of tooth disc.
Otherwise the connection to the ground must be implemented by other measures e.g. cable
links.
Control valves, electrical and electrical/mechanical drives as well as sensors must undergo a
separate conformity check as per ATEX. In doing so the respective safety and explosion
protection information in the operation instructions are to taken into special consideration.
Any modifications whatsoever to the valve are not allowed. The ATEX approval is void with
immediate effect if the valve is modified without prior authorisation (even including painting).
UNI-Geräte GmbH must be consulted before any modifications are made.
Furthermore we point out the guideline 95/C332/06(ATEX 118a), which include the minimum
regulations for the improvement of the health-related situation and the safety of the employees, who
might be jeopardized by an explosive atmosphere.
3.0 Handling
3.1 Transport
For any transport works, the generally recognised technical rules and standards as well as rules for
prevention of accidents must be observed.
In case of transport, storage and stopping, the flange protection caps must be mounted at both valve
flanges.
The goods to be transported must be carefully treated. During transport, the valve must be protected
against strokes, impacts or vibration. The coat of lacquer may not be damaged. Transport temperature
is –20°C up to +60°C.
Never transport the valve at screwed cable glands, appliance plugs or add-on units.
The valve
can be transported at ring nuts, flange borings or by means of a belt under the solenoid drive.
Transport the valve in a case or on a pallet with smooth base and put it softly on plain floor.
Never put
the valve on limit switch box.
The goods must be checked on completeness and transport damage. See also section 9.0
3.2 Storage
If the valve is not installed immediately after delivery, it must be stored properly.
Storage temperature -20°C up to +60°C, dry and clean.
The lacquering protects against corrosion in neutral dry atmosphere. Do not damage colour.
In humid rooms, a drying agent or a heating resp. is necessary because of condensation of
water.
Requirements according to DIN 7716 (products made of caoutchouc and rubber) must be met.
3.3
Handling before mounting
In case of valve with protection caps, they must be removed before being mounted!
Protect against atmospheric influences such as humidity.
Appropriate treatment protects against damage.
