Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply
Regulations.
THE SHOWER MUST NOT BE USED WITH A HOT WATER SUPPLY TEMPERATURE OVER 65ºC.
The Dream range is designed for domestic use only.
Product specification
Dream products are suitable for all gravity, boosted gravity, balanced high pressure and combination boiler systems*.
Pressure range 0.1bar – 10bar max (static).
*The combination boiler MUST have a minimum rating of 24kW (80,000 Btu) and be of the type fitted with a fully
modulating gas valve.
A cold inlet flow regulator is provided for use with combination boiler applications.
If any doubt, please contact the appliance manufacturer before installation commences.
Connections
Dream products are designed for conventional supplies with HOT on the left and COLD on the right as viewed
from the front.
Dream shower valves incorporate ‘push fit’ type connections for use with 15mm British standard copper tube.
Tube should be cut using a rotary type cutter and lubricated using a silicone based lubricant or petroleum jelly
(Vaseline or similar) prior to insertion into the fitting.
If plastic pipe is used, the tube insert must not increase the tube diameter or extend the cut off length by more
than 2mm.
THESE FITTINGS ARE NOT SUITABLE FOR STAINLESS STEEL TUBE
.
Supply lines must be flushed clear of any debris before installation of the unit. Any debris accumulation in the in the
shower valve and head may result in damage and poor performance.
Pipe sizing
Long pipe runs, on both inlet and outlet, will reduce the flow rate at the shower head. If long pipe runs are
unavoidable, use copper pipe rather than plastic. If plastic pipe is used, minimise the number of elbows as pipe
inserts are very restrictive. Consideration should be given to using 22mm plastic or copper pipe especially if a
diverter valve is to be fitted.
