high pressure hose specification. Connect the high pressure hose from the assembled head to the outlet on
the pump.
High pressure hoses left exposed in the protected volume, particularly at height, could be compromised in
a fire. Hoses must therefore be encased in the wall whenever possible. Where possible, hoses must be run
low in the room, all other factors being equal, and in any case the locations of hoses must be chosen so
that they will not be exposed to temperatures above 100°C.
A Quick Connect with Test Point and locking pin are supplied to connect the high-pressure side of the pump
to the sprayhead. A small O-ring is included and already attached to the Quick Connect with Test Point. The
locking pin retains the quick connector in the pump outlet but can be easily removed, for example to drain
water from the high-pressure hose. The Test Point adaptor is required as part of the commissioning
procedure (see page 75).
Figure 67: Connecting the Quick Test Point
IMPORTANT!
Do not attempt to operate the pump without the quick connector O-ring. Always properly
replace the quick connector, O-ring, and locking pin after removal.
The Automist Smartscan Hydra pump unit must be housed close to a 3/4” BSP water supply with an
approved isolation valve to the check valve. A synthetic rubber washer is supplied with each device to
facilitate fitting to the flat-faced outlet.
