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 shut-off valve 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, including the suction service
valve located on the back of the ice machine requires:
Suction Shut Off Valve Insulation
The pre-formed suction shut-off valve insulation is
located in the plastic bag taped to the water curtain.
A. Verify valve and schrader caps are tightened to
specifications (see Step 6).
B. Place insulation over schrader valve cap and left
side of valve. Position the tab between the
mounting bracket and rear panel.
C. Fold insulation and hold against right hand side
of valve while securing with electrical tape. Seal
the line set insulation to the shut off valve
insulation with electrical tape.

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 90% humidity and 90°F (32°C) ambient. When
higher humidity will be experienced, or local code
requies, insulation wall thickness will need to be
increased.
