Lengthening or Reducing Line SET Lengths

Section 2	Installation Instructions

In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser.

The quick connect fittings on the line sets are equipped with Schraeder valves. Use these valves to recover any vapor charge from the line set. When lengthening or shortening lines, follow good refrigeration practices and insulate new tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (143g) of vapor refrigerant charge in each line.

CONNECTING A LINE SET

1.Remove the dust caps from the line set, condenser and ice machine.

2.Apply refrigeration oil to the threads on the quick disconnect couplers before connecting them to the condenser.

3.Carefully thread the female fitting to the condenser or ice machine by hand.

4.Tighten the couplings with a wrench until they bottom out.

5.Turn an additional 1/4 turn to ensure proper brass- to-brass seating. Torque to the following specifications:

Liquid Line	Discharge Line
10-12 ft lb.	35-45 ft lb.
(13.5-16.2 N•m)	(47.5-61.0 N•m)

6. Check all fittings for leaks.

REMOTE RECEIVER SERVICE VALVE

The receiver service valve is closed during shipment. Open the valve prior to starting the ice machine.
