INSTALLATION

Location

The unit represented in this manual is intended
for indoor use only. Be sure the chosen location
has a floor strong enough to support the total
weight of the unit. Reinforce the floor 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 Figure 1.

Figure 1

Tri-Channel Cold Pan

Inside Unit

Provide adequate space along the front and
back taking care to not block airflow to the fan.

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 Tri-Channel Cold Pan 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.
