6.1

Routine Maintenance

All Grant laboratory products are designed to comply with IEC61010-1 and can be flash
tested. Some are fitted with radio frequency interference suppressors. Therefore it is
recommended that only a dc. test is performed.
The over temperature cut-out on the GD120 should be checked periodically by turning
the set over temperature control with a screwdriver anticlockwise until the alarm lamp
comes on. The cut-out should then reset and set-up (see 3.3.1). If the alarm lamp fails
to light with the knob fully turned anticlockwise the unit should be checked by a
competent person.
The liquid level protection should also be checked periodically by lowering the level of
liquid in the bath and noting that the unit cuts out with the top turn of the heater still
Immersed in the liquid.
When hoses are fitted to the pump they should be inspected periodically and replaced as
necessary to avoid hose failure.
No other routine maintenance is required.
6.2

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
