"Oil-Less” Scroll Medical Air Medical Systems

3.0 System Operation (continued)

3.2 Initial Start-up

CAUTION: Complete the prestart-up procedure before continuing with the initial start-up procedure

WARNING:
To prevent electrical shock, ensure that ALL electrical power to the system is OFF, including the
disconnect switches and H-O-A switches on the control panel. The facility’s supply circuit breaker
should also be locked out.

®
NOTE: DO NOT ADD OIL TO THE COMPRESSOR. The design of the LifeLine Scroll compressor is
totally oil-less. It is not necessary to fill the crankcases with oil.

WARNING:
Ensure that all loose articles, packing material, and tools are clear of the system.

Set the H-O-A switches are to O (OFF).

®
Check all voltages supplied to the LifeLine system to ensure they are the required value and phases needed
by the control panel.

Open the inlet isolation valve on each compressor.

Open the outlet isolation valve on each compressor.

Open the receiver isolation valves.

Close the receiver bypass valve.

Close the CO sensor isolation valve.

Close the dewpoint sensor isolation valve.

Close the inlet and outlet valves on both dryer/filter/regulator assemblies.

Close the outlet isolation valve.

Apply power to the system and turn the disconnect switches to "On".

Check for correct direction of rotation of each compressor by momentarily turning the H-O-A switch to the
“Hand” position and observing rotation.

WARNING:
DO NOT RUN THE COMPRESSOR BACKWARDS!

Rotation direction arrows are located on the belt guard (rotation is counter clockwise, facing the compressor
pulley). Correct the rotation, if required, by switching the motor leads at the starter.

REMOVE POWER BEFORE WORKING ON ANY ELECTRICAL CONNECTIONS.
