Engineering Guidelines
Location Requirements
Howe Rapid Freeze Ice Flakers are designed to
operate in ambient room temperatures
between 50°F and 100°F.
Minimum Ambient
Temperature
50°F
The Ice Flaker warranty is void if it is installed
in ambient room temperatures below 50°F.
The Ice Flaker must be located above a sanitary
sewer floor drain hub or trench drain to ensure
proper drainage to the floor. Many designers
slope floors to the sanitary sewer inlets to
manage these wet areas.
If installing the Ice Flaker with a Howe Ice Bin,
ensure that the bin is adequately secured to the
floor so as to prevent the assembly from tipping
when empty.
Water Supply Requirements
Cold water supply to the Ice Flaker must be
totally separate and unaffected by any local hot
water supply.
IMPORTANT
Maximum Ambient
Temperature
100°F
3
This cold water supply must be within the range
of 45°F to 90°F.
Minimum Water
Supply Temp.
45°F
The cold water supply pressure must be within
a 20 PSIG to 60 PSIG range.
Minimum Water
Pressure
20 PSIG
Straight Reverse Osmosis (RO) treated water
should never be supplied to the Ice Flaker.
RO system treated water is aggressive toward
metals and plated surfaces. In addition RO
water will affect the life and integrity of rubber
and plastic material Ice Flaker components. If
only RO water is available, Post‐RO treatment
must be provided to raise pH and mineral
content.
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.
