1. Before connecting the Flowpress Mini to the system ensure that system flushing has been
performed correctly and all foreign matter, including pipe scale, has been removed.
Note: Foreign material from the system coming into contact with the expansion vessel
bladder could cause premature failure of the expansion vessel.
2. Isolating valves MUST be installed on the unit inlet and outlet, beforeconnection to the
flexible hoses to allow the unit to be isolated if required.
The isolation valve on the outlet should be of a lockshield type. See Fig. 10.
3. A drain valve must be fitted on the outlet of the Flowpress Mini before the isolation valve.
See Fig. 10.

and a 15 mm compression fitting. The hose is made water tight with a sealing washer on
assembly, nip tight to 4 to 5 Nm for water tight seal. (Do not overtighten).
