F. Installation of Remote Condenser Unit
WARNING
1. Installation of remote condenser unit must be performed by properly trained
and EPA-certified service personnel.
2. Failure to install the equipment within these guidelines may adversely affect
safety, performance, component life, and warranty coverage.
1. Checks Before Installation
1) Remove the shipping carton, tape, and packing material.
2) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the
fan blade moves freely.
2. Location
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
proper air circulation and ease of maintenance and/or service should they be required.
• The maximum line length for the standard refrigerant charge is 66 feet. Should an
installation require a longer line length, line sizes must be increased and additional
refrigerant must be added. Instead of the standard 3/8" OD discharge line and
1/4" OD liquid line for this icemaker, increase the line sizes to 1/2" OD discharge
line and 3/8" OD liquid line for the entire run. Add 16.5 oz. of R-404A to the system
to compensate for the larger diameter line sizes, then additional refrigerant must be
added. Add .4 oz. of R-404A for each foot over 66 feet to a maximum of 100 feet.
Hoshizaki Technical Support is available at 1-800-233-1940 for recommendations.
• 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 measured fitting to
fitting.
