INSTALLATION
LOCATION AND MOUNTING
The WA is designed to mount on a wall or panel. The unit should be installed so that there are no restrictions on the air inlet or outlet as this will cause
the refrigeration system to operate less efficiently.
Remove the unit from the carton. Using the fastener holes in the unit as a guide, locate the mounting fasteners in the wall of the walk-in or reach-in
cooler. Use #10 screws or 1/4” diameter bolts to secure the unit to the wall. Fan and motor asembly can be accessed be removing the venturi. This
unit must be installed so as to allow drainage of condensate coming off the coil when ordered less drain pan. All WA unit cooloers are optionally available with a drain pan that provides for proper drainage.
The National Sanitation Foundation (NSF) requires that any flush mounted unit be properly and completely sealed, with an approved
NSF sealant, between the unit and the mounting surface.
ELECTRICAL
System electrical installation should conform to all applicable codes and practices. All models will require the connection of power to the fan motor
according to the nameplate motor circuit electrical ratings.
