Thermostatic mixing control valves (hot supply to be 55OC or greater, cold supply to be less than 20 OC to teat mixing valve fail safe).
Procedure for fail safe:
Run the hot tap and check the water temperature with a calibrated thermometer is at correct for the type outlet (according the table detailed above) (+ or - 1oC) with the control at hot.
Shut off the cold supply to the valve and ensure that the discharge shuts off within 2/3 seconds.
If a failure occurs:
strip down,
service,
repair
retest.
Reinstate the supply.
If fail safe does not work valves must be stripped & overhauled (parts replace as necessary).
The valves must then be commissioned to D08 specification.

Check operation of mixer, set temperature (according to guide table below) and simulate fail test (see description below). Record the pipe temperature pre TMV, record the mixed outlet (hot & cold) and NON MIXED outlet (hot & cold) temperatures. Report any defects below.
Fail Test:
A simulated cold water fail test shall be carried out following the overhaul or calibration of each valve by SLOWLY turning off the cold water to the valve and observing the water flow stopping.
A simulated hot water fail test shall be carried out following the overhaul or calibration of each valve by SLOWLY turning off the hot water to the valve and observing the water flow stopping.

Complete an inspection of each AHU as detailed below and complete record form C – LEG06. General check on overall condition of unit. Repair/renovate as required.
Check all thermal and acoustic linings.
Examine for any undue noise, vibration, lack of performance, etc. and report findings.
Check flexible connections, examine security of retaining bands, replace damaged sections if necessary.
Check security brackets and associated supports.
Check tension, alignment and condition of fan drive belts; re-tension / renew (as a complete set) as required.
Check condition of motor/drive casings and motor vent grilles and clean as required.
Check electrical connections.
Check safety guards are secure.
All procedures must comply with the Health and Safety at Work etc Act and COSHH regulations;
Notify all persons working in those areas served by the plant to be disinfected;
Switch off all ventilation systems containing devices to be disinfected;
Spray all internal surfaces of the humidifier section or cooler battery/cooling coil with a 5 ppm chlorine solution until all surfaces are thoroughly wetted, also flood drip trays and drainage system with the same solution and allow to stand for a minimum of two hours;
Spray all internal surfaces of the humidifier and cooler battery/cooling coil with sufficient clean water to remove all traces of the chlorine solution from the device, its drip trays and drainage system;
Restore the plant to normal operation;
If any suspicion arises as to the possible contamination of the system then the microbiologist should be requested to take swab tests from all drain trays and cooler battery/cooling coil tubes and fins;
As an alternative to steps (f) and (g) detailed above, the surfaces may be steam cleaned;
