5.9 Mounting
Prepare and secure the mount to the wall or mounting surface as described below.
1. Determine a secure mounting location.
2.
Cautions:
a.
For a secure installation, use four 8-mm (5/16-in) diameter fasteners (not included). Use stainless steel or zinc plated
fasteners.
b.
If bolts are used, they should extend through the mounting surface and be secured with flat washers, lock washers,
and nuts on the opposite side. Each bolt must have a minimum pull-out strength of 200 kg (450 lb).
c.
If studs are used, they should be anchored in concrete or welded to a steel backer plate. Each stud must have a
minimum pull out strength of 200 kg (450 lb).
c.
If studs are used, they should be anchored in concrete or welded to a steel backer plate. Each stud must have a
minimum pull out strength of 200 kg (450 lb).
d.
If the wall mount is attached to wood or to a blind structure (with no access to the rear), each fastener must have a
minimum pull-out strength of at least 200 kg (450 lb).
3. Locate the four holes or stud locations using the flange as a template (four holes equally spaced on a 69.9-mm (2-3/4-in
bolt circle).
4. Install the mount using bolts or studs at least 8-mm (5/16-in) in diameter.
5. Turn the housing into position and lock the mounting head in by using the supplied 1/8” long-arm hex wrench to tighten
screws. For more information see the MT9208SS & MT9212SS Stainless Steel Mount Instruction Booklet.
5.8 Pressurization
1. The housing is fitted with a standard Schrader valve to allow pressurization with dry nitrogen to 35 kPa (5 lb PSIG)
nominal at one atmosphere.
Using the Schrader Valve add 10psi nitrogen to pressurize the housing.
2. An overpressurization safety relief valve is mounted on the rear cap along with the Schrader valve. The purpose of the
relief valve is to provide a safety pressure blow-off should internal pressure exceed 140 kPa (20 PSIG) at one atmosphere.

CAUTION
PRESSURIZED CONTAINER.
DO NOT open the housing unit until pressure is removed.
DO NOT exceed 70kPa (10 PSIG) at one atmosphere.
