Locate evaporators so that air pattern
covers all of the room. Do not restrict the
inlet or outlet air stream. When installed,
there should be 12”clearance from
bottom of the unit. Always avoid
placement of unit coolers directly above
doors and door openings.
Most evaporators can be mounted with
rod hangers, lag screws or bolts. (use
3/8” and 5/8” stainless steel bolts) Refer
to Figure 7. Mount the unit level so that
condensate drains properly. When using
rod hangers, allow adequate space
between the top of the unit and the
ceiling. (NSF Standard 7). The area
above the unit cooler must be sealed or
exposed in such away to allow hand
cleaning without the use of tools. When
lagging or bolting unit flush to the
ceilings, seal the joint between the top
and the ceiling with an NSF listed sealant.
Ends of open hanger channels must be
sealed to prevent accumulation of foreign
material.
Refer to Figures 1 through 4. Air flow
distance must be considered when
coolers or freezers will not accommodate
all required evaporators on one wall.
Refer to Figure 7. Traps on low
temperature units must be outside of
refrigerated enclosures. Traps subject to
freezing temperatures must be wrapped
with heat tape and insulated.
