Open Receiver Service Valve
There is a liquid line solenoid valve at the outlet of the receiver; refrigerant will not flow to the condensing unit until the ice machine head section is started. Connect power to both the ice machine head section and the Remote condensing unit. Place the ICE/OFF/CLEAN toggle switch into the ICE position, this will allow refrigerant to enter the line set and condensing unit.
Important
All refrigeration valve caps must be reinstalled to prevent future refrigeration leaks.
Step 7 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 ICE/OFF/CLEAN toggle switch into the ICE position. This allows the low side and high side pressures to equalize. Place the ICE/OFF/CLEAN toggle switch in the OFF position. Connect power to the remote condensing unit and allow system to pump down.
Step 8 Insulation Requirements
To prevent condensation the entire suction line including the
The following insulation requirements prevent condensation at 90°F (32.2°C) ambient 70% Relative Humidity. If higher humidity is expected, increase insulation thickness.
The entire line set, including the suction service valve located on the back of the ice machine requires:
Suction | Liquid | Min. Insulation |
Line | Line | Thickness |
|
|
|
3/4 inch | 1/2 inch | 1/2”(13mm) Suction Line |
(19.1 mm) | (12.7 mm) | 1/4” (7mm) Liquid Line |
|
|
|
Important
To prevent condensation the entire suction line including the shut off valve must be insulated. All insulation must be airtight and sealed at both ends.
The minimum requirements are for conditions at or below 70% humidity and 90°F (32.2°C) ambient. When higher humidity will be experienced, insulation wall thickness will need to be increased.
