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 ow. A vented tee connection is also required
for proper ow.
• Drain lines should not be piped directly to the sewer
system. An air gap of a minimum of 5 vertical centimeter
should be between the end of the drain pipes from the
icemaker and condensation drain, storage bin, and water-
cooled condenser (if applicable) and the oor drain.
1. Icemaker
• Icemaker water supply inlet is 1/2" female pipe thread
(FPT). A minimum of 3/8" (10mm) nominal copper water
tubing is recommended for the icemaker water supply line.
• An icemaker water supply line shut-o󰀨 valve and drain
valve should be installed. A ball valve is recommended for
the shut-o󰀨 valve. If another type of valve is used, it should
not have an opening smaller than the water supply line ID
as this can cause a reduced water ow rate which can lead
to poor harvest performance and/or freeze up.
• Icemaker drain outlet is 3/4" FPT. A minimum of
3/4" (18mm) nominal hard pipe is recommended for the
icemaker drain line. Condensation drain outlet is 3/8"
(9.5mm) OD hard tube. The condensation drain line can
be connected to the icemaker drain line or can be run
separately.
Separate piping to approved
drain. Leave a 5cm vertical air gap
between the end of each pipe and
the drain.
