replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
Load Limit
Each Merchandiser has a Load Limit. Shelf life of
perishables will shorten if Load Limit is violated.
AT NO TIME SHOULD THE MERCHANDISER
BE STOCKED BEYOND THE LOAD LIMITS

Basic Operation
The VR3HV-M/F-EP series case cools meat/fish
in two ways:
1. The Spiral Deck Coil under the display deck
cools the meat/fish product by means of con-
tact conduction.
2. The Gravity Coil cools the case and product
via natural air convection.
Spiral Deck Coil is the
primary source
of re-
frigeration while the Gravity Coil acts as a sec-
ondary source. Slow moving air circulation from
the Gravity Coil (GC) and cold contact with the
Spiral Coil (SC) on the deck combine to cool the
product and keep product dehydration low. This
balance is critical to achieve the expected dis-
play life and product temperature. If the product
is lifted off of the deck surface by an aftermarket
display shelf, reduced contact surface trays, or
other means, the benefit of conduction cooling
from the deck Spiral Coil is reduced dramatically.
