Installation Warnings
Before installation read the instructions
WARNING
All electric and mechanical components (control unit, pump
and flow sensors) must be accessible after installation.
• The maximum flow rate the pump is design to work with is
8 Itrs/min for 15mm (electric shower) and 12 ltrs/min for
22mm mixer shower installations.
• Avoid plumbing the pump outlet into the waste piping that
other appliances drain into as there is a risk of induced
syphoning. Use an anti syphon trap in these situations.
• With installations where the floor is being formed in the
screed, we recommend the following minimum falls:
30mm in 1m, 15mm in 500cm, 7.5mm in 250cm.
• Plumbing installation must comply to latest WRAS
regulations.
• The electrical wiring must conform to EU wiring regulations
BS7671:2008 Part 7 (17th Edition).
User Warnings
WARNING
• It is advisable where the property is unattended for an
extended period that the water supply to the shower
is shut off.
• If there is a reduction in pump performance after installation
please contact your installer.
