If signs of breakdown appear, restore the stainless
steel surface. First, thoroughly clean, rinse and
dry the surface. Then, on a daily basis, apply a
high-quality stainless steel polish according to
manufacturer’s instructions.
Heat Tint
Darkened areas, called heat tint, may appear on
stainless steel exposed to excessive heat, which
causes the protective film to thicken. It is unsightly
but is not a sign of permanent damage.
To remove heat tint, follow the routine cleaning
procedure. S
tubborn heat tint will require heavy-
duty cleaning.
To reduce heat tint, limit the exposure of equipment
to excessive heat.
CLEANING HEAT TRANSFER PLATES
The Thermodyne unit operates on the principle
of conduction, rather than convection. Therefore,
it is very important to keep the heat transfer
shelves clean, so heat transfer may take place with
maximum efficiency. It is also very important to
keep the bottom contact surfaces of pots and pans
as clean as possible to ensure even and complete
heat transfer. The surface and flat coating of the
thermal heat transfer shelf is extremely hard, but
will react with strong caustic cleaning solutions
and deteriorate.
CAUTION: Most concentrated soaps and
ammonia cleaners are too caustic to be
used on the Thermodyne unit.
If the coating is destroyed, the heat transfer shelves
will lose their non-stick properties and their surface
hardness.
The cleaners should always be used at the
recommended concentrations. In the case of dry
powders, the powders must not be placed directly
on the surface of the heat transfer plate. Care
must be taken not to scratch the shelf surfaces
when using brushes or pads. If harsh scouring is
needed, use a nylon type scouring pad. NEVER
use steel wool.
It is recommended that a weekly cleaning schedule
be followed to avoid the buildup of heavy food
product deposits. In the event heavy deposits
occur that are difficult to remove with ordinary
cleaning procedures, stronger chemical cleaning
agents may be applied if the products are intended
for food service use and are also compatible with
hard coat anodized aluminum surfaces. When
using these stronger solvents, it is very important
that heat transfer shelves are rinsed thoroughly
with clean potable water after cleaning. Be sure to
remove all traces of the cleaning agent. Between
the regular scheduled cleaning, wipe off the
anodized aluminum surfaces periodically with a
clean damp cloth.
CLEANING DOOR GASKETS
Clean the gasket-sealing surface of the Thermodyne
doors to remove food product acids for maximum
gasket life. Do not use any solvents or sharp
instruments as these will damage the gasket.
Wash with a cloth moistened in a solution of mild
detergent and warm water. Rinse with a fresh cloth
moistened with warm water to remove all traces of
detergent. Wipe dry with a clean cloth. Never apply
food product oils or petroleum lubricants directly
to the door gasket as these will reduce gasket life.
CHANGING FLUID
NOTICE: The Thermodyne Heat Transfer Fluid has
lubricating additives, anticorrosion additives, and
heat transfer properties that may decrease with
the passing of time. Thermodyne Heat Transfer
Fluid will protect the unit indefinitely if the fluid is
changed on an annual basis.
CAUTION: The following procedure is to be
performed by a qualified service technician only.
: Before removing any sheet
metal panels or servicing this equipment,
always perform the Electrical LOCKOUT/
TAGOUT Procedure. Be sure all circuits are
disconnected. Failure to comply with this
procedure can cause property damage,
injury or death.
1. Move Power ON/OFF switches to the OFF
position and perform LOCKOUT/TAGOUT
procedures.
