G. Installation of Remote Condenser Unit
WARNING
1. Installation of remote condenser unit must be
performed by properly trained and 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 blades move freely.
2. Location
CAUTION
1. 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.
2. The maximum line length for the standard
refrigerant charge is 66 feet (20 m). With additional
refrigerant, the maximum line length is 100 feet
(30.5 m). For details, see "I.G.5. Line Set
Exceeding 66 feet (20 m)."
3. The maximum vertical distance between the
remote condenser unit and the icemaker is 33 feet
(10 m) above or 10 feet (3 m) below the icemaker.
These distances are measured fitting to fitting. See
Fig. 8.

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. See Fig. 9.
3. Setup
1) Secure the legs to the remote condenser unit with the
8 bolts and nuts provided. See Fig. 10.
2) The legs have 8 mounting holes. Secure the legs to the
permanent site with 8 bolts (not included).

4. Line Set
CAUTION
1. The icemaker, line set, and remote condenser unit
must contain the same type of refrigerant. Mixing
of refrigerants will result in improper operation and
possible damage to the refrigeration system.
2. The maximum line length for the standard
refrigerant charge is 66 feet (20 m). With additional
refrigerant, the maximum line length is 100 feet
(30.5 m). For details, see "I.G.5. Line Set
Exceeding 66 Feet (20 m)."
1) Route a 1/2" OD copper tube discharge line and a
3/8" OD copper tube liquid line between the remote
condenser unit and the icemaker. Leave a service loop
behind the icemaker to allow the icemaker to be pulled
out for service. See Fig. 11.
CAUTION
1. Ensure that there are no traps and no kinks in the
line set.
2. Do not coil extra line set. Fabricate the line set to
the proper length.
2) Insulate the two copper tubes separately.
3) Install Parker quick connect couplings on each
end. OS-QUICK, an optional Hoshizaki universal
quick connect coupling kit, is recommended.
CAUTION! Before brazing, remove the Schrader
valve core from the access port. When brazing,
protect the coupling by using a wet cloth to prevent
the coupling from overheating.
4) Allow the coupling to cool, then replace the Schrader
valve core.
