2.13 The minimum allowable water temperature is 4 C. Pipework - General 2.14 Secure pipework: Ensure pipework to and from the Mainsboost Plus is independently supported & clipped to prevent forces being transferred to inlet and outlet branches of pump. Flexible hoses supplied must be used. -
Page 8: Location
3 LOCATION - GENERAL 3.11 Access: For emergencies and maintenance the Mainsboost Plus must be easily accessible. 3.12 Protection: The system must be located in a dry position, and protected from freezing. Avoid environments which have a high ambient temperature, high humidity or excessive condensation and salt damage, etc. -
Page 9: Terminology
4.13 Downstream The term ‘Downstream’ refers to the system configuration from the outlet tapping on the Mainsboost Plus Pump, along the distribution header (if configured in this way) and into the distribution pipework and outlets. This includes hot and cold services where both are present (see Fig. 8). -
Page 10: Configuration
5 CONFIGURATION 5.11 Mainsboost Plus is a very flexible solution, offering a patent protected packaged system to suit any type or size of building no matter how large or small the demand is. The following illustrations depict just some of the most typical installations. - Page 11 Note: If a water softener is to be fitted it must be located between the upstream line-in kit and pump/vessel. If high pressure is also required to the drinking tap fit a Stuart Water Conditioner, available from Stuart Turner, rather than a water softener.

6 INSTALLATION Step 1: Remove the Mainsboost vessel from its packaging and check to ensure it is not damaged. Carefully turn the vessel on its side using the discarded packaging to protect it. WARNING: depending on cylinder size this may require two people to complete safely. - Page 13 Note: Do not forget if a water softener is to be installed this has to be included in this pipe run, and additional space must be allocated for this. Do not fit smaller pipework than the upstream line-in kit accepts as this will impair performance.
- Page 14 Step 2: The vessel assembly should then be positioned and checked to ensure there is sufficient space to install the upstream line-in kit between the stopcock and pressure vessel inlet. Refer to the chart below as a guide. Pipe Minimum pipe length required to install the Size upstream line-in kit (mm) (A) 22 mm...

Page 19: Commissioning
8 COMMISSIONING 8.11 System check: Ensure that the electrical supply to the pump is switched off before opening the mains water supply stopcock and checking for leaks. 8.12 Check vessel pre-charge pressure: It is important to have the correct pre-charge pressure in the vessel for your site conditions to optimise performance. - Page 20 8.15 Control module: The control module has been factory pre-set to the following conditions. Settings as per factory preset: Set point SP: 3 bar Diff pressure DIFF: 0.5 bar Low pressure LPR: 0.2 bar High pressure HPR: 4.5 bar Pump run timer PRT: 180 Pump number NPM: 2 (do not tamper)
- Page 21 8.16 On completion of the installation, follow the commissioning process below. Leave pump power switched off. Leave all outlet valves closed. Turn on stopcock and open inlet ballvalve, both pressure gauges on inlet and PRV will start to show movement as the mains pressure fills the system. Check for leaks on all joints made.
