are found on the bottom under the
compressor mounting area and are
clearly tagged - “Water Inlet” and
“Water Waste”. A manual shut-off
valve should be installed in the water
inlet line at the time of installation.
The water pressure must be between
35-140 psig (241-965kPa) for proper
operation.
5. Water cooled and air cooled remote
freezers require at least 12 inches
(30 cm) above the top panel be free
of obstructions. Anything blocking
ventilation of the freezer (including
cone dispensers) will reduce the
efficiency of the freezer.
6. Place the freezer in the final location
and level the machine by adjusting
the legs or casters so that the unit
is level side-to-side, and the front
is approximately ¼” lower than the
rear, to allow proper drainage of the
freezing cylinder.
7. Water Cooled Do not allow freezer to
be in ambient where air temperature
goes below 0°C (32°F),the freezing
temperature of water.
8.
Water consumption
increases if
temperature of entering water is
above 20°C (65°F)
CAUTION
To prevent accidental electrical
shock, a positive earth ground
is required.
2. Supply voltage must be 10%
of voltage indicated on the nameplate.
Also, on three-phase systems,
voltage between phases must be
balanced within 2%. (More than a
6 volt difference between any two
voltage measurements at 208-230
volts indicates a possible imbalance.)
Request your local power company to
correct any voltage problem.
3. An easily accessible main power
disconnect must be provided for all
poles of the wiring to the freezer.
2.3 Electrical Requirements
1. Always verify electrical specifications
on the data plate of each individual
freezer. Data plate specifications will
always supersede the information in
this manual. (See Figure 3-2)
2.2 Installation
1. This freezer is designed for indoor use
and must be protected from outdoor
weather conditions.
2. Where codes permit, we recommend
that the freezer be installed on casters
and have flexible water and electrical
connections for service and cleaning
ability.
3. All models require a minimum 6 inch
(15 cm) clearance on either the side
panels or the rear panel for adequate
ventilation. Freezers designed with
top air discharge require at least 24
inches (61 cm) above the top panel be
free of obstructions. Anything blocking
ventilation of the freezer (including
cone dispensers) will reduce the
efficiency of the freezer.
4. Water cooled double models will
require a 1/2” MPT water inlet and
water waste connection. Both water
condensers are tied together so that
one water inlet and one water waste
is all that is required. The connections
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).
