3. Setup
1) Secure the legs to the remote condenser unit with
the 8 bolts and nuts provided. See Fig. 6.
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 line sizes and refrigerant charge
is 66 feet. With larger line sizes and additional refrigerant, the maximum line
length is 100 feet. For details, see "II.F.5. Line Set Exceeding 66 Feet."
Precharged factory line sets, available as optional equipment from Hoshizaki America,
are recommended. For details, see "II.F.4.a) Factory Line Set Installation." Field
fabricated line sets are allowed. For details, see "II.F.4.b) Field Fabricated Line Set
Installation."
a) Factory Line Set Installation
1) Route the factory line set from the remote condenser unit to the icemaker. Use 3/8" OD
discharge line and 1/4" OD liquid line for line length up to 66 feet. CAUTION! Line sizes
and charge must be adjusted if line length is longer than 66 feet. For details, see
"II.F.5. Line Set Exceeding 66 Feet." Leave a service loop behind the icemaker to
allow the icemaker to be pulled out for service. See Fig. 7. Factory fabricated line sets
are precharged and do not need to be evacuated. If the line set is too long or too short,
see "II.F.4.a)(1) Factory Line Set Modification."
CAUTION
1. Ensure that there are no traps and no kinks in the line set.
2. Do not coil extra line set.
2) Connect the refrigerant lines to the appropriate male fittings on the remote condenser
unit first and then at the icemaker. Make a proper connection as follows:
a. Remove the protective covers from the male fitting and female coupling.
b. Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male
fitting, including O-ring, diaphragm, and threads before making the connection. See
Fig. 8.
CAUTION
Do not use thread sealant on the fittings. Use POE refrigerant oil or Parker
Super O Lube only.
c. Make sure the male fitting and female coupling are properly aligned, then start the
connection by hand to ensure that it is not cross threaded.
d. Tighten the connection with a wrench until it is tight. At this point, the nut has
covered most of the threads on the male fitting.
