Drain Water Piping Requirements; Electrical Requirements - Howe 1000-RLE Installation & Service Manual

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, 2 pole, 208‐230 volt power
supply from a field furnished and installed
disconnect switch is required for each Ice
Flaker.
A dedicated 3 pole, 208‐230 volt 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.
