R-404A vapor to a pressure of 0.1-0.2MPa (1 to 2 bar).

8) If the line set exceeds 20 m, see "II.G.5 Line Set
Exceeding 20 m" for proper charging of the unit.

7) Connect the refrigerant lines to the appropriate malefittings 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 theconnection. See Fig. 12.

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 areproperly aligned, then start the connection by handto ensure that it is not cross threaded.
d. Tighten the connection with a wrench until it is tight.

5. Line Set Exceeding 20 m
CAUTION
The icemaker, line set, and remote condenser unit
must contain the same type of refrigerant. Mixingof refrigerants will result in improper operation andpossible damage to the refrigeration system.
The maximum line length for the standard refrigerant
charge is 20 m. Should an installation require a longer line
length, additional refrigerant must be added. Add 40 g of
R-404A for each meter over 20 m to a maximum of 30.5
m. Your nearest Hoshizaki Service office is available forrecommendations.

See Fig. 16, 17, or 18• External filters, strainers, or softeners may be required
depending on water quality. Contact your local
Hoshizaki distributor for recommendations.
• The icemaker and condensation drain line(s), storage
bin drain line, and water‑cooled condenser drain line
(if applicable) must be run separately. When stacking
units, each unit must have independent drain lines.
• Drain lines must have 2cm tall per 1 m on horizontal
runs to get a good flow. A vented tee connection is also
required for proper flow.
• Drain lines should not be piped directly to the sewer
system. An air gap of a minimum of 5 vertical centimetershould be between the end of the drain pipes from theicemaker and condensation drain, storage bin, andwater-cooled condenser (if applicable) and the floor
drain.

WARNING
1. Water supply and drain connections must be
installed in accordance with applicable national,
state, and local regulations.
2. The icemaker water supply must be potable water.
3. Normal operating water temperature should bewithin 7°C to 32°C. Operation of the icemaker, forextended periods, outside of this normal temperature
range may affect icemaker performance.
4. Water supply pressure should be a minimum of
0.07MPa (0.7 bar) and a maximum of 0.78MPa(7.8 bar). If the pressure exceeds 0.78MPa (7.8 bar),the use of a pressure reducing valve is required.
DO NOT throttle back the supply tap.
5. To prevent damage to equipment, do not operate
the icemaker when the water supply is off, or if thepressure is below 0.07MPa (0.7 bar). Do not run theicemaker until the proper water pressure is reached.
6. This icemaker will not work at sub-freezing
temperatures. To prevent damage to the watersupply line, drain the icemaker if the air temperatureis going to go below 0°C. For details, see "III.C.
