IX. OPERATIONAL GUIDELINES
• The defrost timer must be set to the proper time of day. If the unit is shut
down at any time, the clock must be reset.
• Rail inserts must be in place (under pans) before loading any pans.
• For best results in holding product temperatures, stainless steel pans should
be used in the rail, rather than plastic pans.
• The rail area must have a full complement of pans in place at all times. This
is true even when the unit is not in use with the lid closed, but operational,
especially overnight.
• These units have been designed to operate in an ambient room environ-
ment of 86
° F (30 ° C) or less.
• Do not allow air drafts (such as heat or A/C ceiling registers) to blow on, or
over, the rail area. This will disrupt the air blanket over the product area,
resulting in uneven to poor holding temperatures.
• Rail covers should be closed over the rail whenever slow times of oper-
ations allow.
• Product should be loaded into the rail at a minimum temperature of
35
°
to 36
°
F. The VPS unit was not designed to pull down product
temperature, but rather to maintain it.
• Do not allow blockage of blower fans located in lower base storage
area, such as by stacking boxes, etc. under fans or allowing materials such
as plastic wrap to be sucked into the fan guards.
• Do not block open base refrigerator doors open while loading or unloading.
• When cleaning the rail area, do not wipe any debris on or into the any of the
raised openings in the rail bottom. These are air discharge and air returns
for the VPS system, and must be kept clean, clear and open.
Please follow these simple guidelines for proper VPS operation:
