Opening & Closing the Enclosure
Warning!
The Hazardous Environment flameproof enclosure must NOT be opened when an
explosive gas or dust atmosphere is present, or when the equipment is energized.
Warning!
The Hazardous Environment flameproof enclosure lid must be secured only with the
bolts supplied and these must be tightened to the correct torque value. Contact Ventev
for spare bolts.
Important
Ensure that NO TOOLS come into contact with the flamepath of the enclosure, as this
may cause irreparable damage and render the unit unsafe.
Important
Always re-apply a thin layer of Loctite 8104 or Loxeal GS9 silicone grease to the
enclosure flame paths whenever the Hazardous Environment flameproof enclosure is
opened. This is required to maintain the IP rating of the enclosure.
3.2.1
Opening the Enclosure (Aluminum & Stainless-Steel Enclosures)
The flamepaths of the Hazardous Environment Enclosure are supplied with grease applied to protect them. This can
make the enclosure lid difficult to open as the grease can cause it to stick. Ventev recommend the use of a double
suction lifter. This tool is included with Hazardous Environment Enclosure deliveries and is available from hardware
and builders supply stores. Ventev recommend using a lifter that has a working load of 50kg minimum and approximate
dimensions 300mm x 120mm.
•
Remove all bolts, using a wrench with an 8mm hex head. Store the bolts carefully to avoid damage or loss.
•
Attach the suction lifter as per the instructions provided and release the door.
3.2.2
Closing the Enclosure
1.
Check that the correct grease (Loctite 8104 or Loxeal GS9) has been applied to the flame-path, and that it is free
of damage.
2.
Check all bolts are the correct type and free from damage.
3.
Re-insert the bolts and hand-tighten only.
4.
Using a torque wrench fitted with an 8mm hex head, tighten the bolts in opposite corners of the box, then work
around the box. Use the following maximum torque.
