Connections
Dream DCV products are designed for conventional supplies with HOT on the
left and COLD on the right as viewed from the front.
Dream DCV shower valves are supplied with ¾ inch BSP threads.
Supply lines must be flushed clear of any debris before installation of the
unit. Any debris accumulation 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.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will
attack the working parts of the unit. All soldering must be completed and the
pipe work thoroughly flushed out in accordance with current Water Supply
Regulations prior to connection of the product.
Filters
To ensure ongoing optimum performance, Dream DCV products are
protected by inlet filter assemblies in the internal waterways. Debris
accumulation may result in reduced flow from the shower head and noisy
operation.
As this condition is not covered by our standard warranty terms, it is
suggested that the filters be removed and checked by a competent person.
In the event of any difficulties please contact the Aqualisa customer helpline
for assistance.
Isolating valves
Suitable full way isolation valves must be fitted to both supplies in
accordance with current Water Supply Regulations and our terms of warranty.
Due to their restrictive characteristics, stopcocks and ball type valves that
reduce the pipe bore size must not be used on gravity and boosted gravity
installations.
