WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS RECEIVING YOUR NEW MODEL Congratulations on your purchase of Continental Refrigerator superior foodservice equipment! When your shipment arrives, thoroughly examine the packaging for any punctures, dents or signs of rough handling.

WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS Four (4) bolts secure the cabinet to the wooden skid. The bolts are located at each end on the underside of the skid. In order to remove these bolts, tilt the cabinet backwards and place wooden blocks at each end in order to hold it in its tilted position. Using a ¾” socket or open end wrench, remove the bolts and carefully slide the cabinet off of the skid.
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS “UC” series models and units provided with the Front-Breather Option do not require any clearance around the the sides or back of the cabinet, since they take in and exhaust air under the cabinet and through the front grill, under the door. The air flow under the cabinet and through the front grill cannot be restricted. (see “Front Breather Kit” under “Optional Accessories”).
WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS INSTALLING LEGS AND LEVELING If your new unit is supplied with adjustable legs, they will be packed in the accessory carton in the cabinet. Each model has four leg mounting holes on the bottom of the cabinet (see Figure 4).

Move the door to the desired position by hand or by gently tapping on the edge with a rubber mallet.
