WARNING: Disconnect electrical power to Unit to prevent personnel injury before
attempting any internal maintenance. Only qualified personnel should service internal
components or electrical wiring.

PREPARING UNIT FOR SHIPPING, STORING, OR RELOCATING

CAUTION: Before shipping, storing, or relocating Unit, syrup systems must be sanitized
and all sanitizing solution must be purged from syrup systems. All water must also be
purged from plain and carbonated water systems. A freezing ambient environment will
cause residual sanitizing solution or water remaining inside Unit to freeze resulting in damage to
internal components.

2. Make sure soft drink tanks contain sufficient amount of syrup for Unit operation.
3. Unit With Air-Cooled Refrigeration System.
Circulating air, required to cool the refrigeration systems condenser coil (see Figure 16), is drawn in
through louvers on front and exhausted out through louvers on sides and back of Unit. Make sure louvers
are not obstructed and refer to CLEANING CONDENSER COILS in this section.
Unit With Water-Cooled Refrigeration System. (see Figure 17)
The high-pressure cutout switch, located inside the lower control box, will shut the Unit refrigeration
system down when overheated (high head pressure) caused by lack of cooling water. After problem has
been corrected and the head pressure has decreased, reset button on the high-pressure cutout switch
must be pressed to restart the refrigeration system.
