CAUTION
The remote condenser unit is intended for outdoor use. Normal operating
ambient temperature should be within -20°F to +122°F (-29°C to +50°C).
Operation of the remote condenser unit, for extended periods, outside of this
normal temperature range may affect icemaker performance.
The remote condenser unit must be positioned in a permanent site under the following
guidelines:
• A firm and flat site.
• A dry and well ventilated area with 24" (61
cm) clearance in both front and rear for
ease of maintenance and/or service should
they be required. See Fig. 9.
• The maximum line length for the standard
refrigerant charge is 66 feet. With
additional refrigerant, the maximum line
length is 100 feet. For details, see "II.G.5.
Refrigerant Charge (Line Set Exceeding
66 Feet)."
• The maximum vertical distance between
the remote condenser unit and the
icemaker is 33 feet above or 10 feet
below the icemaker. These distances are
