UNCRATING AND INSPECTION

AT BOTTOM OF UNIT.

Unpack unit and components from container.
Remove all visible packing material and inspect unit
for damage. If damage is discovered, initiate a claim
immediately with the carrier that handled the
shipment.

ASSEMBLY AND INST ALLATION
A. Counter Mounting (524SB, 536SB):If the unit is to

be installed on a counter, attach legs as shown
below.

Using a flat tipped screwdriver, the Button Plugs
can be removed from the holes at the top rear of
the unit. Unit may now be hung from wall by
inserting the bolt heads into the mounting holes in
the unit.

C. Heater Tubes:

All models use quartz sheathed Heater Tubes
which are held in position by spring loaded
Sockets which push on the end of the Heater
Tubes. To install or remove a Heater Tube, grasp
the end of the Heater Tube (NEVER THE
MIDDLE), push one end of the Heater Tube into
one of the spring loaded Sockets and insert or
remove the other end of the Heater Tube into or
out of the remaining Socket as shown below.

LEGS SCREW INTO LEG HOLES

Anti-skid pads are available at no charge and may
be adhered to the foot section of each leg to
prevent sliding. Call 1-800-225-3958 for details.

CAUTION

Use of these pads is not approved by the
National Sanitation Foundation.

B. Wall Mounting (524SBW, 536SBW): Mounting

bolts (2 1/2" lag bolts) have been supplied with
your Cheese Melter. At the back of the Cheese
Melter there are either two (524SB) or three
(536SB) 5/8" holes which are plugged with
nickel platted Button Plugs. These holes are on
16" centers and large enough so that the head of
the Lag Bolt will slip inside the hole.

Screw the Lag Bolt into wall studs on 16" centers
and level. Screw heads should be 1/8" away from
the wall as shown below.

The heater tubes are clear quartz (like glass) and
quite fragile. When removing them from the
cardboard tubes it is very important that no
bending pressures are applied or they will
immediately snap in the middle.

EXTREME CAUTION
SHOULD BE EXERCISED.
TUBES ARE VERY FRAGILE
