INSTALLATION REQUIREMENTS
Please read IMPORTANT SAFETY INFORMATION and SPECIFICATION sections before
undertaking the plumbing installation.
NOTE: If the recommended dynamic pressure and flow is not available, there could be a
noticeable reduction in performance from the shower head.
If it is intended to operate the shower at pressures above the maximum or below the
minimum stated, contact Customer Experience for advice.
1. The Tri-HUB MUST NOT be positioned where it will be subjected to freezing conditions.
Any pipework MUST BE insulated to avoid being frozen.
2. The installation must be in accordance with Water Regulations/Bylaws.
3. DO NOT use jointing compounds on any pipe fittings for the installation.
4. DO NOT solder fittings near the shower unit as heat can travel along pipework and damage
components.
5. Compression or demountable push-fit fittings can be used to connect to the shower Inlet
and Outlet connectors.
6. NOTE: DO NOT use non-demountable push-fit fittings on the Inlet and Outlet as this will
prevent servicing and may invalidate the warranty of the product.
7. Important: An additional full bore stop valve (complying with Water Regulations) must be
fitted in the mains water supply to the shower as an independent means of isolating the
water to carry out maintenance or servicing. If this isolator and/or Tri-HUB is fitted in a loft
space, the loft must have a fixed access ladder and be boarded, with appropriate lighting
from the access point to the isolator.
8. Important: Before completing the connection of the water supply to the inlet of the shower,
ush out the pipework to remove all swarf and system debris.
9. Important: The Tri-HUB must be mounted on a even vertical surface otherwise the Tri-
HUB’s inbuilt sensors will not allow for the ENVi
®
shower to operate.
10. Position of the shower: Refer to Fig.1 for correct location of the Tri-HUB. Always mount
the Tri-HUB vertically and allow enough room for the installation of elbows or straight
connectors onto the Inlet and Outlet stems at the base of the Tri HUB.
IMPORTANT Water Regulations: It is required that the shower head be ‘constrained by a
fixed or sliding attachment so that it can only discharge water at a point not less than 25mm
above the spill-over level of the relevant bath, shower tray or other fixed appliance’.
If the riser kit is supplied with a ‘soap dish hose retainer’ or bespoke ‘hose retainer’, it will in
most cases meet this requirement. If the shower head can still be placed within a bath, basin
or shower tray within the 25mm limit, then a double check valve, or similar, MUST be fitted in
the supply pipework to prevent back-flow.
