Example of Multiple Units with Horizontal Airflow
Evaporator Units
• Do not place the evaporator above or close to door openings. This will help prevent potential icing problems.
• Allow a minimum clearance equal to or greater than the coil height on all sides of the coil for proper air flow and
service access.
• Use the evaporator coil for a template to locate and drill the mounting holes (1/2” diameter).
• Place a 1” and a 1-5/8” washer on each nylon bolt and insert through the drilled mounting holes in the ceiling from
the exterior of the walk-in ceiling panel.
NOTE: Nylon bolts are supplied to prevent thermal transfer between the exterior of the walk-in and the interior of the walk-
in. Do not use metal bolts.
• Lift the evaporator coil until the nylon bolts extend through the mounting brackets.
• Install washers and secure with nuts. Tighten until the coil is firm against the ceiling. The evaporator coil must be
level.
• Additional information is available in the installation manual supplied with the evaporator.
CAUTION
Failure to observe clearance and air flow requirements will result in poor system performance and premature
