This section provides procedures for servicing the individual components of the
Companion 1000/T Portable. Where applicable, instructions are included for removal,
disassembly, operational check, cleaning, inspection, adjustment, reassembly, and
installation.
After removing a component, visually inspect it for damage or any indication that the
part should be replaced. Unless otherwise specified, replace as needed with a new part.
Refer to the exploded view illustrations and the Companion 1000/T parts list in
Section 6.
Personal injury can occur from the uncontrolled release of pressurized
gaseous and liquid oxygen. Empty liquid oxygen contents and vent
system pressure before servicing.
Concentrated oxygen. Increased risk of fire. Place unit in a well-
ventilated area away from sources of ignition when setting a flow to
empty unit.
Injury to eyes from flying objects possible. Wear eye protection when
servicing the Portable.
The Companion 1000/T can be emptied by setting the flow control at its highest setting
and allowing the unit to run until all liquid oxygen is depleted. When the liquid oxygen
is depleted, you can leave a flow set on the control while working on the unit to provide
continuous system venting.
After making repairs, always verify proper system operation by performing the
functional tests in Section 3.
The Companion 1000/T Portable uses two types of fittings: compression tube fittings
and National Pipe Tapered (NPT) fittings. Proper make-up of these pressure fittings is
essential to leak-free operation.
