2.1 Uncrating and Inspection
CAUTION
Be sure to properly support
the machine when removing
bolts and installing legs or
casters.
When the unit is received and while
the carrier is still present, inspect the
shipping carton for any damage that
may have occurred in transit. If the
SHOCKWATCH® label indicates red and/
or the carton is broken, torn, or punctured,
Figure 2-1 Machine Bolted to Shipping Base
note the damage on the carrier’s freight
bill and notify the carrier’s local agent
immediately.
1. Remove the carton from the
pallet, and move the machine as close as
possible to the permanent location.
2. Remove the shipping bolts on
the bottom of the freezer (gure 2-1) and
install either the legs or casters (gure
2-2).
FRONT BACK
NOTE: Screw casters
or legs all the way in
coupling, then adjust
out to level with 1/4
inch slope to front.

2.2 Installation
Models 876, 876B, 876C, 876RH, 876BRH, 876CRH & 875 Batch
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code.
1. This freezer is designed for indoor use
and must be protected from outdoor
weather conditions.
2. Where codes permit, Electro Freeze
recommends that the freezer be
installed on casters and have exible
water and electrical connections for
easier service and cleaning.
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 18
inches (45 cm) above the top panel be
free of obstructions. Anything blocking
ventilation of the freezer (including
cone dispensers) will reduce the
efciency 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
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
efciency of the freezer.
6. Place the freezer in the nal 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)
