1. In positioning the freezer, be sure
that it is accessible for periodic
maintenance checks. Where codes
permit, we recommend that the
freezer be installed on casters and
have flexible water and electrical
connections for easy servicing and
cleaning.
2. Air-cooled models require a mini-
mum eighteen inches (18'') clear-
ance on the top panel for adequate
ventilation. Anything (including cone
dispensers) in this area will reduce
the efficiency of these models.
3. Double-cylinder water-cooled models
will require a 1/2" MPT water inlet
and water waste connection. Single
cylinder freezers require a 3/8" MPT
water inlet and waste connection.
The connections are found under the
rear of the freezer and can be
identified by removing the rear
panel. A manual shut-off valve
should be installed in the water inlet
line at the time of installation. Also
be sure that inlet water pressure is
above 35 psig and below 140 psig. If
the pressure drops below 35 psig,
condenser pressure will increase
and result in more prolonged periods
of running and overall inefficiency.
NOTE
: Water-cooled freezers are
not equipped with vacuum breaker
valves. Be aware of local codes
concerning this and all plumbing
requirements.

Installation Procedures
4. The inlet water temperature should
not be higher than 90°F. When inlet
water temperature is higher than
90°F water usage becomes exces-
sive and production capacity is
reduced.
5. Place the freezer in its 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 1/4" lower than the
rear, to allow proper drainage of the
freezing cylinder. If the unit is moved
to a new location, be sure to check
level and readjust, if necessary.
