Planned Maintenance Programmes
(Preventative/Precautionary Maintenance)
The frequency and extent of attention required will vary according to prevailing site and operational conditions. In
applications (such as non-healthcare) where the risks to the user are too slight to justify the full In-service Test
Procedure and maintenance logging process, the procedure under Performance Check is suggested to cover
average duty and site conditions. In all other cases it is recommended that a routine of preventative maintenance
be employed which is based upon assessment of the risks to the user. The following practices are intended to
support such a routine:
- In-service tests
- Regular temperature checking in between In-service tests
- Maintenance of a log of In-service tests and temperature checks together with details of cartridge replacements
and any other service work.
