CASER

®

DISPLAY COOLER CURTAINS

A refrigeration specialist should take part in the installation.

The curtains will significantly lower the case temperature, so the

thermostat control must be adjusted accordingly.

It is advisable to use a thermostat temperature control rather than

a pressure switch control system.

Defrost cycles may also require adjustments.

The curtain is meant to attach at the top and hang down over the front of the kick rail.
The top of the curtain is attached by means of a Velcro (hook & loop) fastening system.
The loop (soft) part of the Velcro is already attached to the curtain itself.
The hook (harder) part is the loose strip that has been shipped with the curtain. This
strip has an adhesive back, which will be attached either to the canopy face; or to the
vertical metal plate just inside the ambient air screen (with cases using an ambient air
screen).

Installation with ambient air screen

If the case uses an ambient air screen,
it is imperative that the Caser be
mounted inside of that air flow, so the
warm air flows outside of the vinyl cur­tain. Or, install a switch to de-energize
the ambient air curtain while the Caser
is in use.
Thoroughly clean and dry the metal
plate surface. Then attach the hook Velcro to it (in a continuous strip) pressing it hard into
place. (Caution: do not run your fingers over the hook material as it may cause skin
burns). Allow at least one hour for the adhesive to set before installing the curtains.

NOTE:
Recommended mounting is on the
exterior canopy facing. Be sure,
however, to turn off the ambient
fans, to avoid trapping the warm air
inside the case.

Thoroughly clean and dry the canopy
facing. Remove the paper backing
from the Velcro strip (hook side) and
attach to the face in a continuous strip.
Be sure the Velcro strip is straight and
level with the floor before pressing hard
into place.

(Caution: do not run your fingers
over the hook material as it may
cause skin burns).

Allow at least one hour for the adhesive
to set before installing the curtains.

For stocking or cleaning the case, each
curtain can be folded in half by using the
Velcro pieces on the front of each cur­tain. This eliminates the need of com­pletely removing each curtain or having
to throw it over the top of the case.

• Attach the curtains by pressing the soft (loop) strip on the curtains to the hard (hook)
strip on the case.

• Cleaning can be done with warm water. A recommended cleaning solution is a 10/1
mix of water/mild detergent in a spray bottle. Spray the cleaner on two clean cloths or
paper towels and, holding one in each hand, pull down on each strip. Liquid sprays
made special for vinyl also work well.

•To prolong curtain life, it is advisable to rotate curtains every 2-4 weeks to help reduce
the wear on curtains positioned over busy sections of the case.

Installation with no ambient air screen

• Check to make sure none of the multi­deck cases are air defrost. The Caser
will not work on air defrost cases.

• Install the Caser behind the ambient air
band on the cases. Not all cases have
the ambient band. This must be
checked. Ambient fans must be discon­nected and a sheet metal block installed
in the fan housing, so the refrigerated air
and ambient air cannot mix. This is very
important. The case will not operate
properly if this is not completed.

• Coolers will run much colder after the
Caser curtains are installed. Check
cooler temperatures after 24 hours and
reset thermostat if necessary.

• Defrosting - Defrost cycles in time and
occurrence will be shorter and fewer.

• All refrigeration controls must be
checked to see if they are operating
properly. If you are unfamiliar with the
cooler settings, have a refrigeration con­tractor check all the cooler controls and
set if necessary.

• Check all anti-sweat heaters in the cool­ers to see if they are working properly.
Price tag molding heaters can be dis­connected - big energy savings when
used with the Caser. Talk to customer
about using time clocks or dew point
sensors to cycle the remaining anti­sweat heaters.
