Ensure that the FireSAFE is positioned to allow access for examination and service. A
minimum of 75cm should be left all around the FireSAFE unit.
Adequate drainage facilities and protection from water damage in the immediate vicinity of
the FireSAFE unit must be provided.
The FireSAFE unit must not be installed into roof spaces, the small level of vibration
associated with any rotating equipment will cause disturbance, and considerable
water damage could result if a leak occurs. Please provide drainage facilities for the unit in
case of leakage or loss of water during commissioning and service.
The FireSAFE unit should not be installed in an unventilated small space, ensure
adequate ventilation for the motor.
8.8 Breaktanks and Mains water connection
In some situations, and with the permission of the Water Utility company, it may be
possible to connect the FireSAFE unit directly to the town water mains. A dedicated
suction pipe will be required, the diameter of which should match the pump suction as an
absolute minimum.
In situations where the town mains supply cannot be utilised directly it will be necessary to
install a water storage tank (break tank) between the incoming mains water supply and the
FireSAFE unit, it must however have a type AB Air Gap, supplied and installed in accordance
with the Water Byelaws Regulations. Grundfos can offer a suitable break tank.
Check that the water storage tank has adequate capacity to meet/exceed the demand.
8.9 Installation General Requirements
The suction and discharge pipework must be at least the same size as the FireSAFE
suction and discharge ports, as a smaller size may result in reduced pump performance
or increased system resistance leading to a reduced flow. This may also cause damage to
the pump.
The installation suction and discharge pipework may need to be properly supported
before being connected to the FireSAFE unit so that the FireSAFE unit is not stressed.
The pipework installation to and from the FireSAFE unit should be in accordance with
local water authority regulations, best industry practice and according to the design
recommendations in BS 9251 latest revision.
The electrical installation of the FireSAFE unit should be in accordance with the latest
issue of the I.E.E. regulations and according to BS 9251 latest revision.
Pump must be filled with water and have been correctly primed/vented prior to the
pump being ran.
