A mixture of 20% nitric acid and 1.5% hydrofluoric acid (or hyrochloric
acid). Swab solution on surface allowing it to remain until rust is loosened.
Immediately follow with a clean water rise. (This method should ONLY be
used if SEVERE rust and scale stains are present.)
•
Oxalic acid 2% to 5% in warm water. Swab solution on surface allowing it

CLEANING COPPER SURFACES: FLO-THRU MODELS, 316/317 SERIES:
Copper surfaces can be cleaned using commercially available detergent
preparations specifically indicated for copper use. Copper surfaces will not
tarnish when washed with detergent solutions that contain small amounts of the
chemical compound 1-, 2- or 3-benzotriazole. It is important, however, before
using the detergents to determine any possible effect the presence of this
compound and any other ingredients might have on the incubation work being
conducted. Contact the manufacturers of the commercially available detergents
and obtain all necessary information on the chemical and physical properties of
the compositions.
TEMPERATURE READOUT CALIBRATION: ALL MODELS:
Place a scientifically accurate thermometer in the chamber, on a center
shelf and allow the incubator to stabilize at some set temperature. If the digital
temperature readout does not agree with the thermometer, take the trimmer pot
tool, insert in calibration pot on control panel and adjust until readout matches
the measured temperature.
UNIT REPAIRS:
In the event that your unit becomes inoperative, consult with your local
dealer for assistance.
