Important
Failure to flush and add inhibitor to the system will invalidate the
appliance warranty.
It is important to check the inhibitor concentration after installation, system
modification and at every service in accordance with the inhibitor
manufacturer. (Test kits are available from inhibitor stockists.)
For information or advice regarding any of the above contact Baxi

5.2.7 Showers
If a shower control is supplied from the appliance it should be of the
thermostatic or pressure balanced type. Thermostatic type shower valves
provide the best comfort and guard against water at too high a
temperature. Existing controls may not be suitable - refer to the shower
valve manufacturer.
5.2.8 Expansion vessel (CH only)
The appliance expansion vessel is pre-charged to 1.0 bar. Therefore, the
minimum cold fill pressure is 1.0 bar. The vessel is suitable for correct
operation for system capacities up to 120 litres. For greater system
capacities an additional expansion vessel must be fitted.
For GB refer to BS 7074 Pt 1. For IE, the current edition of IS 813
Domestic Gas Installations.
Checking the charge pressure of the vessel - to check the charge
accurately ensure the system is cold. It is also necessary to relieve the
pressure by draining the boiler. Using a suitable gauge check the pressure
at the valve on the underside of the vessel. Adjust the pressure as
required and repressurise the system.
5.2.9 Pump available head
This is a two-speed (85% CH and 100% DHW) high static head pump fit
for installation on any type of single or double pipe CH system. The
automatic air valve incorporated in the pump allows quick venting of the
heating systems.
