Pump Connections - Stuart Turner Showermate Series Installation Instructions Manual

Pipework Connections (Cold)
The pump must be supplied with a dedicated feed direct from the cold water
storage tank.
The supply must be air free and connection of the feed pipe to the tank should be via a
tank connector, positioned at a slightly lower level (25 mm minimum) than the feed pipe to
the hot water cylinder.
Pipework Connections (Hot)
When a hot water cylinder or storage tank is used, ensure the pipework size from the
cold water storage to the hot water storage is of adequate size and a minimum of 22 mm.
The pump must be supplied with a dedicated feed direct from the hot water
cylinder or storage tank.
The supply must be air free and connection to the cylinder can be made by one of the
methods shown in Fig. 9.
When the method of connection is to be made via the expansion pipe, the cold water
storage cistern should be at least 1 metre above the top of the hot water cylinder.

Pipework Connections (Connection between pump and system outlet)
This should run as far as possible in 22 mm copper tube. Pipework should only be
reduced to 15 mm copper at pump and if necessary when entering the terminal fittings.
By this method the maximum performance of the pump will be maintained.

WARNINGS:
Do not use stainless steel, chrome or nickel plated pipe with Stuart
