Step 5 Pressure Test and Evacuate The Line Set

and CVD Condensing Unit

Schrader valve core removal tools that allow for removal

and installation of the valve cores without removing

manifold gauge set hoses are recommended to

decrease the evacuation time.

Leave the line set shut off valves closed (front seated).

Pressure test the line sets and CVD condensing unit

with 150 psig of dry nitrogen. Add nitrogen at the line set

shut off valves located at the back of the ice machine.

Complete the pressure test, verify no leaks are present

and remove the nitrogen from the system before

connecting the vacuum pump. Connect a vacuum pump

to both of the line set shut off valves located at the back

of the ice machine head section. Evacuate to 500

microns minimum. To completely evacuate the CVD

condensing unit, continue the evacuation for 30 minutes

after reaching the 500 micron point.

If required, the line set and condensing unit can be

evacuated from the schrader valves located in the CVD

condensing unit. Schrader valve core removal tools (that

allow for putting the cores back in without removing

vacuum pump hoses) must be used if evacuating from

the condensing unit side.

Pressure test the condensing unit and line set with 150

psig of dry nitrogen. Add nitrogen at the condensing unit

Schrader valves. Complete the pressure test, verify no

leaks are present and remove the nitrogen from the

system before connecting a vacuum pump. Connect the

vacuum pump to both the Schrader valves and evacuate

to 500 microns minimum.

Disconnect the vacuum pump from the condensing unit

access ports prior to proceeding. Open refrigeration

system shut off valves.

The suction line, liquid line and receiver service valves

are closed during shipment and installation.
