5.2 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 installations that can recirculate hot discharge air. Such installations require supplemental ventilation
to remove the hot discharge air. A fan with a thermal switch is a good option.
An ambient temperature of 75°F (24°C) provides the optimal capacity. As the ambient temperature increases, the dispenser
capacity decreases. A self-contained, air-cooled dispenser can release a large amount of heat into the environment;
therefore, it is essential that the HVAC system be able to handle this heat load.
5.3 Dispenser Mounting
Countertop - Flush Mounting: One method of installation is to set the dispenser directly on a countertop. If permanently
mounting to the countertop, use the mounting information located in the “Diagrams and Schematics” section of this
manual to drill holes in the countertop. Once installed, with side panels removed, seal the dispenser to the countertop
using a bead of clear silicone caulk around the base of the frame.
Countertop - Leg Mounting: Another countertop option is to use support legs that raise the dispenser four inches off the
countertop (purchased separately). The legs mount to the same frame locations as the countertop mounting bolts. This
allows easy cleaning under the dispenser and meets most state and local health department codes.
Base Cart: A roll-around base cart (purchased separately) can be used when a suitable countertop location is not available
or it is desired that the BIBs and syrup pumps be located with the dispenser. If a base cart is used, the dispenser must be
secured to the cart using 3/8”-16 UNC bolts. Failure to do so can result in serious injury should the dispenser fall off the
cart. Once installed, seal the dispenser to the cart using a bead of clear silicone caulk around the base of the frame.
5.4 Connecting to Electrical Power
The dispenser is shipped with a three-prong, 20 A, locking-type plug. The mating wall receptacle must be a NEMA L6-20R
to match the amperage rating of the dispenser. If the plug on the dispenser is replaced with an alternate, it must have the
same amperage rating and provide a grounding prong. The dispenser must be connected to a dedicated circuit with the
proper amperage fuse rating.
The dispenser requires a single phase 230 VAC ± 10%. If the line voltage is above or below the required, a buck-boost
transformer must be used. Operation above or below the required voltage may damage the dispenser and cause
inconsistent performance. Operation outside the recommended voltage range also voids all warranties.
