9.0 Maintenance and service
9.1
Routine maintenance
The float liquid level protection should 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.
No other routine maintenance is required.
9.2
Cleaning
Clean the outside of the equipment with a damp cloth, using water only. Do not use
chemical cleaning agents. Before using any other cleaning or decontamination method,
check with Grant Instruments or your local representative to make sure that the proposed
method will not damage the equipment. Scale on immersed parts can be removed using
chemical de-scaling products designed for use on equipment that has metal parts.
De-scaling products may be toxic and manufacturer ’s instructions should
always be followed
9.3
Fuses
The T100IN fuses are internal and should not need to be replaced. Please contact the
Grant Instruments service department if the unit has a fuse fault.
9.4
Replacing the mains cord
Any replacement mains cord used with the T100IN must meet the same specification as
the one originally supplied with the unit to maintain the safety of the unit.
The cable must have the following markings; <HAR>, HO5VV-F 3Gx1mm2 90°C and be
rated to carry 10A. The mains plug and IEC connector must carry approvals from a
European certification body (e.g. BSI, VDE or equivalent).
9.5
Routine safety tests
If routine tests are to be made, we recommend a test of the integrity of the protective
earth conductor and an insulation test at 500V DC. Routine flash tests are not
recommended for any electrical equipment, because repeated high voltage tests degrade
insulation materials.
