G. Installation of Remote Condenser Unit
WARNING
1. Installation of remote condenser unit must be
performed by properly trained and certifi ed service
personnel.
2. Failure to install the equipment within these
guidelines may adversely aff ect 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. Loction
CAUTION
1. The remote condenser unit is intended for outdoor
use. Normal operating ambient temperature should
be within -29°C to +50°C. Operation of the remote
condenser unit, for extended periods, outside of
this normal temperature range may aff ect icemaker
performance.
2. The maximum line length for the standard
refrigerant charge is 20 m. With additional
refrigerant, the maximum line length is 30.5 m. For
details, see "II.G.5. Line Set Exceeding 20 m."
3. The maximum vertical distance between the remote
condenser unit and the icemaker is 10 m above
or 3 m below the icemaker. These distances are
measured fi tting to fi tting. See Fig. 8.

The remote condenser unit must be positioned in a
permanent site under the following guidelines:
• A fi rm and fl at site.
• A dry and well ventilated area with 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 20 m. With additional
refrigerant, the maximum line length is 30.5 m.
For details, see "II.G.5. Line Set Exceeding 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.
