CLEANING AND PREVENTIVE MAINTENANCE
PROTECTING STAINLESS STEEL, EPOXY COATED AND
PLASTIC SURFACES
It is important to guard against
corrosion in the care of stainless
steel surfaces. Harsh, corrosive,
or inappropriate chemicals can
completely destroy the protective
surface layer of stainless steel, epoxy
or plastic. Abrasive pads, steel wool,
or metal implements will abrade
surfaces causing damage to this protective coating and
will eventually result in areas of corrosion. Even water,
particularly hard water that contains high to moderate
concentrations of chloride, will cause oxidation and pitting
that result in rust and corrosion. In addition, many acidic
spills left to remain on metal surfaces are contributing
factors that will corrode surfaces.
Proper cleaning agents, materials, and methods are vital
to maintaining the appearance and life of this appliance.
Spilled items should be removed and the area wiped as soon
as possible but at the very least, a minimum of once
a day. Always thoroughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly as
possible after rinsing.
CLEANING AGENTS
Use non-abrasive cleaning products designed for use on
stainless steel surfaces. Cleaning agents must be chloride-
free compounds and must not contain quaternary salts.
Never use hydrochloric acid (muriatic acid) on stainless
steel surfaces. Always use the proper cleaning agent at the
manufacturer’s recommended strength. Contact your local
cleaning supplier for product recommendations.
CLEANING MATERIALS
The cleaning function can
usually be accomplished
with the proper cleaning
agent and a soft, clean
cloth. When more aggressive
methods must be employed,
use a non-abrasive scouring
pad on difficult areas and
make certain to scrub with
the visible grain of surface
metal to avoid surface
scratches. Never use wire
brushes, metal scouring pads,
or scrapers to remove residue.
1. Ensure that the correct Operation and Care Manual is
available to all users.
2. Ensure that all users have been properly trained in
unit’s operation.
3. Do not overload cabinet.
• Blanket Warmer: 1" (25mm) from top interior of unit
• Fluid Warmer: See electrical/capacity page
4. Inspect condition of plug and cord. Replace if damaged.
5. Clean dust from outer vents surrounding the unit and
around top of bonnet (if applicable).
6. Check door gasket integrity. Are there any tears? Is the
gasket worn or loose? Make sure seal is tight to unit
body. Replace gasket if integrity is compromised.
7. Check air temperature sensor mount on the interior
of chamber. Is the guard in place? Are the wires in
good condition?
8. Check insert assembly (depends on unit):
• Blanket Warmer: Check the blanket support
assembly and shelf. Is the assembly in place?
Are any pieces missing?
• Fluid Warmer: Check basket and side rail condition.
Do baskets move smoothly and freely?
9. Check condition of casters or feet. Ensure components
are secure and tightly threaded.
10. Check control panel overlay condition. Are there any
tears or excessive wear on the graphic? Does the
control work properly when buttons are pushed?
11. Check that all control and interior LEDs light up.
12. Is the set temperature comparable to the actual
temperature displayed? Check cavity air temperature
with a quality thermocouple placed 1” from the cavity
sensor not allowing it to touch any surface. Monitor for
approximately one hour in an empty cavity.
Contact service for immediate repair
if any of the above problems exist.
CAUTION
TO PROTECT SURFACES, COMPLETELY
AVOID THE USE OF ABRASIVE
CLEANING COMPOUNDS, CHLORIDE
BASED CLEANERS, OR CLEANERS
CONTAINING QUATERNARY SALTS.
NEVER USE HYDROCHLORIC ACID
(MURIATIC ACID) ON STAINLESS STEEL.
NEVER USE WIRE BRUSHES, METAL
SCOURING PADS OR SCRAPERS.
