1. Step 6 im i 8 a Optional y n Step 2 Step 7 Step 7 Optional 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 PORTA PAK is still in use 1 Index the selector valve to the second cylinder and note the gauge pressure to assure that it is full 2 Close the drained cylinder and open the corresponding bleeder valve to relieve pressure on the hand tight nut 3 Install a known full cylinder in its place and connect CGA 347 hand tight nut to cylinder valve Close the bleeder valve on the connect whip and open the cylinder It is now ready for use when the other cylinder s pressure descends to 500psi SHUTDOWN Make sure all personnel have egressed the hazardous area and have disconnected from the breathing air system 1 Close cylinder valves 2 Depressurize manifold pressure by pulling the relief valve ring 3 Open bleeder valves 4 Close the regulator by turning the control knob counterclockwise 5 Reinstall dust caps 6 Remove connections from cylinders Reinstall cylinder valve covers if applicable HIGH PRESSURE AIRLINE GENERAL MAINTENANCE amp INSPECTION M2.

3. Index the selector valve so that it points to the open cylinder At this time the low pressure warn ing alarm will sound until it sets itself at approximately 1000psi 69 bar Check reading on gauge to verify that it is full Close the cylinder Step 5 Set the required respirator pressure with the regulator control knob and bleed pressure at either the relief valve or by partially engaging a male plug into one of the respirator couplings This depressurizes the manifold and simulates low cylinder pressure The low pressure warning alarm should sound at approximately 500psi 35 bar Step 6 Index the selector valve toward the other cylinder and open At this time the low pressure warn ing alarm will resound until it sets itself at approximately 1000psi 69 bar Check reading on gauge to verify that it is full When both cylinders are known to be full reopen the first one tested Optional Install high pressure connect whip to auxiliary inlet port CGA 347 This step can be done after Step 6 or at anytime during operation of the system Step 7 Couple respirators and lengths of hoses to the manifold and readjust pressure regulator if neces sary The system is now operational Optional If pneumatic equipment is to be used which requires a different pressure than the respirators set the secondary low pressure regulator accordingly Locking regulator push to lock pull to unlock
