Leak Check The Refrigeration System, Open Valves

Section 2	Installation Instructions

Step 6 Leak Check The Refrigeration System

Leak check the new line set connections at the ice machine head section, condensing unit and S trap as well as all factory joints throughout the entire system. Disconnect power to the remote condensing unit. Place the rocker switch into the ON position. This allows the low side and high side pressures to equalize for leak checking. Place the rocker switch in the OFF position. Connect power to the remote condensing unit and allow system to pump down after leak checking is complete.

Step 7 Open The Valves Prior To Starting The Ice Machine

A.Slowly backseat (open-turn counterclockwise) the suction line shutoff valve.

B.Slowly backseat (open-turn counterclockwise) the liquid line shutoff valve.

Open suction and liquid line shut-off valves

Open Valves

Important

All refrigeration valve caps must be reinstalled to prevent future refrigeration leaks.

Verify O-ring in schrader valve caps are intact and reinstall on shutoff valves to prevent refrigerant leakage. Replace shutoff valve access caps and torque to the following specifications.

Torque Values

Stem	18-20 ft. lbs. (24.4-27.1 Nm)

Caps	12-15 ft. lbs. (16.3-20.3 Nm)

Schrader Core	1.5-3 in. lbs. (0.17-0.34 Nm)

Step 8 Insulation Requirements

To prevent condensation the entire suction line must be insulated. All insulation must be airtight and sealed at both ends.

The following insulation requirements prevent condensation at 90°F (32.2°C) ambient 90% Relative Humidity. If higher humidity is expected, increase insulation thickness.

The entire suction line set requires:

Suction Line	Liquid Line	Min. Insulation
Suction Line	Liquid Line	Thickness
		Thickness

		1/2 in. (13 mm)
5/8 in. (16 mm)	3/8 in. (10 mm)	Suction Line
5/8 in. (16 mm)	3/8 in. (10 mm)	1/4 in. (7 mm)
		1/4 in. (7 mm)
		Liquid Line

Important

To prevent condensation the entire suction line must be insulated. All insulation must be airtight and sealed at both ends.

The minimum requirements are for conditions at or below 90% humidity and 90°F (32°C) ambient. When higher humidity will be experienced, or local code requires, insulation wall thickness will need to be increased.
