display cabinet

welcome

Thank you for your purchase of a Winston
CVap® display cabinet. The benefits you will
enjoy from this cabinet include longer hold
times, better quality food, quicker service,
higher productivity, and safer food
temperatures.

This CVap holding cabinet utilizes Controlled
Vapor (CVap) technology. Using a
combination of dry and moist heat, CVap
holding cabinets keep foods hot and maintain
texture, whether moist or crisp, throughout
long serving periods. The two electronic
differential control dials are easy to
understand and reliable. The controls never
need field calibration. The FOOD TEMP

dial allows precise control of food

temperature from 90 to 180˚F (32 to 82˚C).

The FOOD TEXTURE dial maintains just
cooked texture with settings labeled very
moist, firm moist, and crisp. No guesswork
required.

CVap display cabinets are built with durable
stainless steel construction and full insulation,
and they are designed for high volume usage.

If you have any questions, or if anything held
in your CVap holding/proofing cabinet doesn't
meet your satisfaction, please call our
Customer Service Center at 1-800-234-5286
or 502-495-5400, or email us at

Please read this entire use & care manual
before operating your CVap holding cabinet.
The manual contains important safety
information and operating instructions.

As is the case with many kitchen
appliances, your CVap holding cabinet
should be used with caution. Please read
the following warnings to avoid injuries.

Electrical Hazard

Can cause serious injury or death.

Do not attempt to install or service this appliance un­less you are a licensed electrician or trained servicer.

1. Because this appliance utilizes high
voltage, it should only be installed and
serviced by a licensed electrician or
trained servicer. Attempting to install or
service the appliance yourself could result
in serious, potentially fatal injuries.

2. If an electrical shock is felt when touching
appliance, shut off power immediately
(either pull power cord or turn off circuit
breaker) and call a trained servicer for
repair. Failure to do so could result in
serious, potentially fatal injuries.

doors or reaching into the appliance, as
heated vapor can quickly cause burns.

Contamination Hazard

Can cause serious illness or damage to
appliance.

Clean appliance daily to avoid potential contamination
hazard.

5. Clean appliance daily to prevent buildup of
food residue or chlorides, which can also
damage stainless steel and contaminate
food. Failure to follow proper cleaning

procedures can void your warranty.

6. Prior to using appliance for the first time,
perform the daily cleaning procedure
listed on pages 10 and 1 1.

Burn Hazard

Can cause injury.

Allow 30 minutes for appliance to cool before
attempting to clean.

7. Always allow appliance to cool before
cleaning, to avoid potential burns.

3. Always turn power switch off any time
appliance is not in use.

Burn Hazard

Can cause serious injury.

Avoid heated vapor when opening or closing
appliance door.

4. This appliance utilizes heated water vapor,
which transfers heat much more quickly
and efficiently than dry air of the same
temperature. Use caution when opening

High Temperature and Grease Hazard

Can cause damage to appliance.

Avoid placing appliance near high heat or in grease
laden atmosphere.

8. Do not place appliance in areas where air
temperature exceeds 100˚F (38˚C). A heat
shield may be required to prevent heat
exposure and grease laden vapors from
affecting the appliance if near heat, vapor,
or grease generating devices (such as grills,
steamers, ovens, etc.). Excess heat and
grease inside the appliance cavities may
cause electrical components to fail.

Shipping Damage

Examine equipment thoroughly for shipping
damage before, during and after unloading.
All Winston products are carefully inspected
and verified to be in good condition before
leaving our factory. The carrier delivering
your cabinet has assumed responsibility for
its safe arrival. If you notice any damage
(obvious or hidden), a claim must be made to
the carrier.

notice damage that was concealed by
packaging or crating, contact the carrier in
writing to notify them of the damage. The
carrier should agree to inspect the damage
within 15 days. Please retain all packing
materials. The carrier will supply an
inspection report and the required claim
forms.

Water Supply

In order to operate properly, the evaporator in
this cabinet must be filled with clean, potable
water.

Obvious Loss or Damage

Please note any obvious loss or damage on
the freight bill or express receipt, and have
the carrier’s agent sign to acknowledge the
claim. The carrier will supply the necessary
forms. If you do not obtain and complete the
forms before the carrier's agent departs, the
carrier might refuse your damage claim.

As water evaporates, minerals in the water
will deposit on the surface of the evaporator.
These mineral deposits will inhibit the transfer
of heat. Deposits can also degrade and
damage stainless steel. To avoid mineral
deposits clean the appliance daily. It is
advisable to contact your water utility for
advice on minimizing deposit buildup.

Concealed Loss or Damage

Sometimes loss or damage is not obvious
until the product has been unpacked. If you

ventilation requirements

Ventilation clearances - To operate properly,

the appliance will need sufficient space for air
circulation. Allow at least 2” (51mm)
clearance on all sides, particularly around
ventilation holes. Care should be taken to
prevent placing the appliance close to
anything combustible. It must be installed with
its supplied legs, feet, or casters. Counter top
appliances supplied without legs or casters
may be placed directly upon a counter top of
non-combustible material. In this situation, the
appliance may have to be sealed to the
counter top with a food-grade silicone sealant
(check local health codes). Half size
appliances may be stacked upon each other
using only a Winston supplied stacking kit
and following the instructions enclosed with
the kit. Your warranty may be void if you do
not adhere to these ventilation requirements.

High Temperature and Grease Hazard

Can cause property damage.

Avoid placing appliance near high heat or in grease
laden atmosphere.

Do not place appliance in an area where
ambient temperature (air temperature around
the appliance) exceeds 100°F (38˚C). A heat
shield may be required to prevent excessive
heat exposure and grease laden vapors from
affecting the appliance if adjacent to heat,
vapor, or grease generating devices (such as
grills, steamers, ovens, etc.). Excess heat
and grease inside the appliance cavities may
cause electrical components to fail.

Vent hood - Generally this appliance does

not need to be installed under a mechanical
ventilation system (vent hood). Check local
health and fire codes for requirements
specific to your location.
