The battery compartment is accessed by loosening the four (no.5) Allen key
bolts on the Battery Cover Plate
–
note that the bolts do not unscrew
completely, they remain with the plate
.
To replace batteries follow the instructions below:
1)
First clamp the Battery Cover Plate so that the spring under
the plate does not exert unequal force on the bolts
ensuring that bolts loosen smoothly without forcing the
thread.
This can be done by clamping the plate with the thumb on the
“
GasClam 2
” logo and the rest of the fingers under the head.
2)
Loosen the bolts first by applying force on the long end of
the Allen key in a cross pattern (1,2,3,4).
3)
When the bolts are loose and while still clamping the
Battery Cover Plate unscrew fully.
4)
To remove the batteries tilt the GasClam 2 until they slide
out.
5)
Replace with only GasClam 2 approved batteries positive
terminal facing DOWN into the GasClam 2.
6)
Check the integrity of the O-ring, if damaged it MUST be
replaced. The O-ring should be checked every time the
batteries are replaced.
7)
When the O-ring is resting on the battery compartment
push the cover plate down evenly to ensure it travels down
square. This will prevent damage to the O-ring.
The cover plate must sit flush with the head of the GasClam 2
otherwise the intrinsic safety of the unit will be compromised.
8)
Again clamp the plate with the thumb on the “
GasClam 2
”
logo and the rest of the fingers under the head.
9)
First tighten the bolts by hand taking care that the bolts
tighten smoothly without crossing the threads.
10)
When the bolts are finger tight use the Allen Key, alternate
between the bolts in a cross pattern (1,2,3,4) applying
moderate force on the short end of the Allen Key.
11)
Repeat this several times tightening the bolts in a cross
pattern.
12)
When the bolts are tight repeat one more time applying
moderate force on the long end of the Allen key.
If this procedure is not followed carefully, damage to the O-ring may be caused compromising the intrinsic safety
of the Unit.
