Platinous User’s Manual 7
Precautions in Usage
DO NOT introduce corrosive substances into the equipment.
Humidifying water or specimens which generate substances that
corrode stainless steel or silicone rubber can drastically shorten
service-life of internal parts, including the refrigerator and packing.
Corrosive Substances:
- Corrosive substances include, but are not limited to, chlorine, chlorides and
acids. Though apparently harmless at ambient temperature, these substances
can readily corrode circuit boards and other parts when the equipment is run at
high temperature and high humidity.
- Even trace amounts of corrosives in the humidity water supply or released by
the test items will become concentrated in the humidifying tray during
extended periods of humidity operation. If corrosion is observed in the
humidifying tray during extended high humidity testing, it should be drained
and refilled daily to flush out the corrosive contaminants. This can be done by
programming the humidity control OFF for at least 30 seconds in the humidity
control program which will drain the humidifying tray and refill it when humidity
mode is resumed (see “Program Mode Setup” in the SCP-220 Controller
Instruction Manual.)
- Damage to the equipment by prohibited substances is not covered by the
Espec warranty.
