MAINTENANCE
Cleaning: Stainless steel will resist corrosion;
however, it is not impervious to it. Proper
maintenance of the stainless steel bath chamber
will help assure many years of service.
CAUTION
AVOID SPILLING HARSH CHEMICALS
ONTO THE BATH, AS CORROSION OF
THE STAINLESS STEEL MAY RESULT.
CLEAN-UP AND DECONTAMINATION FROM
SPILLS OF HAZARDOUS MATERIALS ARE
THE RESPONSIBILITY OF THE USER.
It should be cleaned regularly with mild soapy
water and rinsed with distilled water. Should algae
or other undesirable microorganisms form on the
top of the bath media, add a little formaldehyde or
quaternary ammonium germicide, available from
Thermo (P/N 3166250).
Before using any cleaning or decontamination
method except those recommended by the
manufacturer, users should check with the
manufacturer that the proposed method will not
damage the equipment.

Removing Discoloration: Should the stainless
steel ever become discolored by iron rust, use the
following procedure to remove all traces of the rust
and restore the stainless steel.
WARNING
OBSERVE
THE
PRECAUTIONS! USE HEAVY GLOVES OR
OTHER ADEQUATE HAND PROTECTION.
WEAR GOGGLES OR OTHER ADEQUATE EYE
PROTECTION. ONLY WORK IN AREAS WITH
ADEQUATE VENTILATION.
Prepare a solution of 20% nitric and 1.5%
hydrochloric acid (if preferred, a 2% to 5% solution
of warm oxalic acid may be used). Swab solution
over surface, allowing it to remain until all rust is
loosened. This will usually take 1 to 2 minutes.
As soon as rust is loosened, immediately flush with
clean water until all acid is removed.
Periodic Safety Check
Test the operation of the Hi-Limit thermostat, as
described on page 5, every three months.
