STEP 5)
Couple respirators and lengths of
hoses to the manifold and readjust
pressure regulator if necessary. The
system is now operational.
STEP 3)
Open one cylinder. At this time the low pressure
warning alarm will sound until it sets itself at
approx. 1000psi (69 bar). Check reading on
gauge to verify cylinder is full. Close the
cylinder.
STEP 4)
LOW PRESSURE
ALARM TEST
Set the required respirator pressure
with the regulator control knob and
bleed the pressure at either the re-
lief valve or by partially engaging a
male plug into one of the respirator
couplings. This depressurizes the
manifold and simulates low cylin-
der pressure. The low pressure
warning alarm will sound at ap-
proximately 500psi (35bar). Open
the other cylinder. Check reading
on gauge to verify cylinder is full.
STEP 1)
Install cylinders on MULTI-
PAK
TM
tray. Secure cylinders
by tightening the straps at the
buckle and mate the velcro sec-
tions to prevent slipping.
STEP 2)
Install universal CGA-347 hand
tight nuts to the cylinder valves
and tighten. Insure both bleeder
valves are closed by turning
fully clockwise.
SETUP PROCEDURE
OPERATION
When the cylinder in use has been depleted to approximately 500psi (35 bar), the low pressure warning alarm will
sound indicating that the cylinder needs to be replaced.
To change a cylinder while the MULTI-PAK
TM
is still in use:
1) Open the second cylinder and note the gauge pressure to assure that it is full.
2) Close the drained cylinder.
3) Open the bleeder valve to relieve line pressure. Remove the CGA-347 hand-tight nut.
4) Remove the drained cylinder and install a full cylinder in its place. Reinstall the CGA connections.
Close bleeder valves. The cylinder is now ready for use when the other cylinder’s pressure descends to 500psi.
Note: The system is equipped with check valves that will prevent back flow from the other cylinder in use.
