INSTALLATION
Location
The unit represented in this manual is intended for indoor use only. Be sure the chosen location has a floor or counter strong enough to support the total weight of the unit. 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.
The outline dimensional drawing for the unit is shown below in Figures 1.
Figure 1
48” Refrigerated Back Bar (RUF 48)
Inside Unit
Provide adequate space along the front, back and sides taking care to not block airflow to the fans.
Outside Unit
Be sure that the unit has access to ample air; avoid hot corners and locations near stoves and ovens.
Leveling
Be sure that the unit is 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.
Stabilizing
Use the leg adjustments to insure that the unit is solid to the floor surface at all four contact points. Insure that the unit does not “rock” when pressure is applied to the top corners.
Electrical Connection
The RUF 48 is available as a 120VAC, 60 Hz or as a 220VAC, 50 Hz dependent on model. All electrical connections should be performed by a certified electrician and should comply with local electrical codes for your municipality.
WARNING
REFER TO THE AMPERAGE DATA LIST IN THE SPECIFICATIONS OR THE SERIAL TAG DATA AND YOUR LOCAL CODE OR THE NATIONAL ELECTRICAL CODE TO BE SURE UNIT IS CONNECTED TO THE PROPER POWER SOURCE. A PROTECTED CIRCUIT OF THE CORRECT VOLTAGE AND AMPERAGE MUST BE RUN FOR CONNECTION OF THE SUPPLY CORD OR PERMANENT CONNECTION TO THE UNIT. THE POWER MUST BE TURNED OFF AND DISCONNECTED WHENEVER PERFORMING MAINTENANCE OR REPAIR FUNCTIONS.
