Top Discharge
(for Open Well)
6. The Cold Isla case was designed and tested using
stainless steel hotel pans. The use of any other
material (such as crocks) may insulate the product
and thus, not be kept cold. Containers made of
materials other than stainless steel is discouraged and
may void warranty.
7. Avoid the use of supplemental flood or spot lighting.
Display light intensity has been designed for
maximum visibility and product life at the factory. The
use of higher output fluorescent lamps (H.O. and
V.H.O.), will shorten the shelf life of the product.
Important Steps
1. Do not set temperature too cold, as this causes
product dehydration. Refer to case specs section for
proper settings.
2. Temperature control should be by means of a
T-STAT and Suction Stop Solenoid at each case.
Do not use EPR valves, Liquid Line Solenoids or
electronic control devices of any kind, as these
allow temperature swings causing dehydration and
excessive energy consumption.
COLD CASE CLEANING
Long life and satisfactory performance of any equipment
are dependent upon the care given to it. To insure long life,
proper sanitation and to minimize maintenance costs, the
unit should be cleaned thoroughly and frequently.
It is essential to establish and regulate cleaning procedures.
This will minimize bacteria causing dis-coloration which leads
to degraded product appearance and significantly shortening
product shelf life.
Cleaning COLD Cases
Cases with cold wells were designed and tested using
stainless steel hotel pans. Containers made of materials
other than stainless steel are discouraged and may void
warranty.
SHUT OFF FAN DURING CLEANING PROCESS. It can
be unplugged within the case, or shut off case at the
source.
