10.1 FREQUENCY OF REGULAR SERVICING
The need for servicing is normally identied as a result of the regular performance auditing.

The purpose of servicing regularly is to monitor any changes in performance due to changes in either
the system or the product. This may highlight the need to adjust either the supply system or the product.
These products should be audited 6 to 8 weeks and again 12 to 15 weeks after commissioning. The
results are to be compared against original commissioning settings. If there are no signicant changes
at the mixed temperature outlet then a 6 monthly servicing cycle may be adopted. Otherwise, servicing
checks should be carried out more frequently (e.g. every 4 months).
Follow the recommended auditing and maintenance procedures detailed in sections 9 & 12. During
servicing, note the following:
1. Repeat the procedure of recording and checking supply temperatures. (The same type of measuring
equipment should be used)
2. If the temperature has changed signicantly from the previously recorded valves, the following should
be checked:
a. All in-line or integral valve lters are clear of obstruction.
b. All in-line or integral check valves are clean and working properly to prevent backow.
c. Any isolating valves are fully open.
d. The thermostat is free of debris
3. When satised with the mixed outlet temperatures re-record the temperatures.
11.1 Outlet cleaning
Traditional “ow straightener” type outlets have recently been identied by extensive research as an
area most likely to harbour bacteria. This product uses an Armitage Bioguard outlet which replaces this
traditional ow straightener with a fully open copper-lined waterway. This greatly reduces the risk of
bacteria build-up whilst the copper lining has natural anti-microbial properties.
Outlet is suitable for autoclaving (remove o-ring if exceeding 80°C).
In the interests of infection control and health hygiene, the Armitage Bioguard Outlet is a supplement to,
not a substitute for, standard infection control practices. Continue to follow all current protocols, includ-
ing those practices related to cleaning and disinfection of surfaces. Refer to HTM04-01 for more details.

On a regular basis the outlet should be inspected and cleaned.
To unscrew and remove the outlet, use an adjustable spanner on the ats (20mm). To ret, hand tighten
and then use the spanner until the outlet has bottomed in the bore. Take care not to over tighten.
In areas where lime scale build-up is prevalent this should be avoided by regular cleaning. If it should
build up, it will have to be removed. An inhibited proprietary scale solvent can be used such a kettle des-
caling solvent but it is important to follow the manufacturer’s guidelines. After descaling it is important to
rinse the parts thoroughly in clean water. Clean carefully and do not use abrasive materials or scrapers
Note: Lime scale deposits should be removed prior to using any disinfection treatments.
OUTLET FILTER: The Armitage Bioguard outlet can be removed (as described below) & re-
placed with a universal lter adaptor, see section 18. The adaptor will accept most lter types
which are externally threaded M24x1.
