7 Maintenance and service
All Grant Laboratory products are designed to comply with IEC1010-1 and can be flash tested.
Some are fitted with radio frequency interference suppressers. Therefore it is recommended that
only a d.c. test is performed.
Inspect and replace where necessary any worn or damaged hoses.
The overtemperature cut-out should be checked periodically by turning the set overtemperature
control anticlockwise until the alarm lamp comes on. The cut-out should then reset and set-up. If
the alarm lamp fails to light with the knob fully turned anticlockwise the unit should be checked by
a competent person.
No other routine maintenance is required.
DO NOT RETURN THE TANK
7.1 Cleaning
The cases can be cleaned with a damp cloth after disconnection. Do not use solvents. The
immersed parts can be cleaned using proprietary heating element cleaners. CAUTION: these
may be toxic - follow the cleaner manufacturer's instructions.
Before using any decontamination or cleaning method except that recommended, check with our
Service Department, or in other countries with our distributor, that the proposed method will not
damage the equipment.
