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; 
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.
