MAINTENANCE
General
1.
The maintenance of this product must be carried out in accordance with instructions
given in this Manual, and must be conducted by designated, qualified and
competent personnel.
2.
Rada products are precision-engineered and should give continued superior and
safe performance, provided:
- They are installed, commissioned, operated and maintained in accordance with
the recommendations stated in this Product Manual.
- Periodic attention is given as necessary to maintain the product and its associated
installation components in good functional order. Guidelines are given below.
3.
The use of main supply-line or zone strainers (recommended maximum mesh
aperture dimension is 0.5 mm) will reduce the need to remove debris at each
mixing valve point.
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.
1.
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 cartridges replaced and any other service work.
2.
Thermostatic mixing valves only operate correctly when all components have
been serviced and have been tested for correct performance. If any component
is faulty, including the thermostat the valve will not operate correctly and could
allow full hot water to pass through the valve.
3.
As with all other thermostatic mixing valves, the critical sensing element in the
Rada 215/222 series together with other “critical components” will exhibit wear
over a period of time and usage. All of the critical components are contained
within the Thermostatic cartridge.
