FBD 77 Series, Installation And Operation Manual

INSTALLATION

General Location Requirements

A flat, level location is required for proper installation.  When using a counter, ensure it will support the weight 
of the dispenser plus the weight of any equipment placed near it.   See the specifications page for specific 
equipment weights.

Self Contained Refrigeration Models

Adequate clearance around the dispenser is required for proper air flow.  Failure to provide proper clearance 
will reduce capacity and can eventually damage the refrigeration system.  See the specifications page for 
clearance requirements.

Be careful of enclosed, or “doghouse”, installations that can re-circulate hot discharge air.  Installations such 
as this require supplemental ventilation to remove the hot discharge air.  A fan with a thermal switch is a good 
option.  Airflow from the fan should be at least 850 CFM.

Although the dispenser will operate in temperatures up to 104°F, an ambient temperature is 75°F will provide 
the optimal capacity.   As the ambient temperature increases, the dispenser capacity decreases.

Because this equipment is designed for high capacity, a self contained air 
cooled dispenser will reject a large amount of heat into the environment.  It 
is essential that the HVAC system be able to handle this heat load.  The 
average heat load over time that is rejected into the environment is shown 
in the table.  If this is a concern then a remote condensing model might be 
considered instead.

Remote Condensing Models

Remote condensing models utilize a condenser assembly external to the building and are designed for 
ambient temperatures from -10°F to 120°F.  This configuration removes the heat and fan noise from the inside 
environment and reduces the air conditioning load during the warm season.  Because air flow is not a 
high concern with this set up, this style dispenser is suitable for enclosed spaces and zero side clearance 
installations (dispensers side by side).

Remote condensing models utilize a small air recirculation fan to assist in drying out any internal 
condensation.  This fan is located on the top of the dispenser and runs continuously.  Do not stack objects on 
top of the dispenser as this will block the airflow and damage the fan.

Dispenser Mounting

Countertop - Flush Mounting: 

 When the dispenser is mounted on a counter top, one method of installation 

is to set the dispenser directly on top of the counter top.  If permanently mounting to the counter top, use the 
mounting information located in the “Dispenser Mounting” section of this manual to drill holes in the counter 
top.  Once installed, with side panels removed, seal the dispenser to the countertop using bead of clear silicone 
caulk around the base of the frame.

Countertop - Leg Mounting:

 Another counter top option is to use support legs that raise the dispenser four 

inches off the counter top (Purchased separately. Contact customer service).  This allows easy cleaning under 
the dispenser and meets most state and local health department codes.  The legs mount to the same frame
