Step 4 Connecting the line set

To prevent oxidation of the copper, purge line set and condensing unit with dry nitrogen while brazing.

A. Connect the Line Set to the Remote Condensing Unit

!Warning

The QuietQube Condensing unit contains refrigerant charge. The two refrigeration valves must remain closed until proper installation of the line sets is completed.

The line set shut-off valves must remain closed and be protected from heat during the brazing process. Wrap the valves in a wet rag or other type of heat sink prior to brazing. Cool braze joint with water immediately after brazing to prevent heat migration to the valve.

MINIMIZE THE TIME THE

REFRIGERATION SYSTEM IS EXPOSED TO THE ATMOSPHERE (15 MINUTES MAXIMUM)

SUCTION LINE

LIQUID LINE

B. Connect the Line Set to the Ice Machine Head Section

!Warning

The ice machine head section ships from the factory pressurized with R404A refrigerant. Recover the refrigerant from both suction and liquid line access ports prior to cutting into refrigeration lines.

Cut the suction and liquid tubing with a tubing cutter, leaving enough tubing to easily braze.

Connect the line set.

Cool braze joint with water immediately after brazing to prevent heat migration.

Step 5 Pressure Test and Evacuate Line Set and Ice Machine Head Section

Suction and liquid line set shutoff valves must remain closed until pressure testing and evacuation are complete.

Pressure testing and evacuation can be performed from the ice machine head section or CVD condensing unit shut-off valves.

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.

Pressure test @ 150 psi (1000 kPa) for a minimum of 15 minutes.

Minimum evacuation level is 500 microns.

Suction and liquid line shut-off valves must remain closed until evacuation and pressure testing are complete.
