MAINTENANCE OF WARM WATER SYSTEM
In-service tests should be carried out regularly to monitor and record the performance of the
Apricus Tempermate in accordance with AS 4032.3. Deterioration in performance can indicate the
need for servicing of the valves and/or water supply. If, during these tests, the mixed water
temperature has changed significantly from the previous test results, record the change before re-
adjusting the mixed water temperature. If the final mixed water temperature is greater than the
permitted values, we recommend that the details quoted in Installation and Commissioning sections
are verified and that service work is required.
A Maintenance Check Log form is provided at the back of this manual, which can be copied and used
as a template for recording purposes.
YEARLY SERVICE
We recommend that at least every 12 months, or more frequently if the need arises, that the
following aspects are checked to ensure that the optimum performance level of the valves are
maintained.
With reference to the exploded diagram:
1. On the Caleffi 252225TM series valves, the inlet filters (12) on both the hot and cold water
supplies can be removed for cleaning by unscrewing the inlet union nuts and carefully
pulling apart the connecting pipework.
2. The built-in check valves (11) on the Caleffi 252225TM series valves can be accessed in a
similar way to 1) to ensure freedom of operation and correct seating.
3. In case of service work, the internal components of the valve can be disassembled for
cleaning and descaling.
a) Remove the cap of the valve (1) and the locking nut (2)
b) Remove the upper body (3) using a suitable spanner
c) Remove parts 5-7 noting the correct orientation
d) Remove all signs of scale and dirt from the internal part using a suitable descaling
solution.
e) Lubricate the o-rings with an approved grease and re-assemble all the components.
For best performance we recommend that all o-rings are lubricated every 6 months.
Once the serviceable items have been dealt with, we recommend that the valve is re-
commissioned as described in ‘Commissioning the TMV’ ensuring that a suitably accurate
thermometer is used.
Should the valve still not function correctly, it may be necessary to replace the thermal element or
other components. Refer to spare part kits and contact our Agents for details and advice.
