Generally, filtration of cold supply water is
recommended. Howe offers a complete line of
replaceable core cartridge filter treatment
systems designed to improve ice quality and
extend the life of the Ice Flaker.
This filtration will also reduce supply water
related service problems if changed at least
every six months or depending upon local water
conditions.
A dedicated 1/2” ODS copper cold water supply
should be located within 4 feet of the Ice Flaker
complete with hand shut off valve.
A 3/8” OD copper tube should connect the field
installed shut off valve with the Ice Flaker water
inlet connection located at the rear of the
machine.
Drain Water Piping Requirements
The Drain Water Piping figure above illustrates
the recommended piping to a floor sanitary
sewer hub or trench drain. The two vertical
pipe drops should drain water through an
indirect water connection with an “Air Gap”.
Code authorities having jurisdiction may dictate
other indirect water connection requirements.
The figure depicts two separate drain lines
which are required to ensure the Ice Flaker
does not inadvertently flow Water Sump Drain
water into the Ice Bin or Carts in the event of a
backup or any other malfunction.
Electrical Requirements
A dedicated 15 amp power supply from a field
furnished and installed disconnect switch is
required for each Ice Flaker.
A dedicated 3 pole power supply from a field
furnished and installed disconnect switch is
required for each Remote Condensing Unit. The
amperage of the power supply circuit must
match the selected Remote Condensing Unit
supplied by Howe with respect to Minimum
Circuit Amperage (MCA) and Maximum
Overcurrent Protection Device (MOPD)
nameplate information.
A two conductor control circuit is required to
interconnect the Ice Flaker with the Remote
Condensing Unit interlocking relay.
