Installation and Operation of: 

Refrigerated Counter RUF48 Digital

INSTALLATION

INSTALLATION - LOCATION

Units represented in this manual are intended for indoor use only. Be sure the location chosen has a floor or count-

er strong enough to support the total weight of the units. Reinforce the floor or counter if necessary to provide for 

maximum loading. For the most efficient operation, be sure to provide good air circulation inside and out.  These units 

should be located so that they can be moved for service.  Major service to the 

refrigeration system is done from the rear of the cabinet. 

INSTALLATION – Inside Unit

Take care not to block air flow to the fans and allow space along the front, back and sides. 

INSTALLATION – Outside Unit

Be sure that the unit has access to ample air; avoid hot corners and locations near stoves and ovens.

CAUTION:

This unit exhausts air to the bottom and the back.  Do not seal the unit to the wall or set unit on a curb.  The ventilation 

slots in the kickplate must remain open.

INSTALLATION – Leveling

Be sure that the units are placed on a firm, flat surface/floor. Check for cracks in flooring or tile and avoid these areas 

if possible. If necessary place support pads, properly rated for the weight of the unit, to “bridge” uneven or cracked 

flooring. Level unit accordingly. 

INSTALLATION

 

 

Stabilizing

Make sure the unit is installed on a flat surface to insure that the unit is solid to the floor at all four contact points. 

Insure that the unit does not “rock” when pressure is applied to the top corners.
