8.5 Frost protection
The FireSAFE unit must be protected from freezing conditions. The unit may require
trace heating or lagging. If the FireSAFE unit is being stored during periods of frost the whole
unit should be drained to avoid damage. Remove all drain and vent plugs and allow the pump
to drain. Do not replace the plugs until the
FireSAFE unit is to be used again.
The pump must be vented/primed before it is started again.
See section 5 for priming screw location.
Loosen but do not remove the priming screw until water flows from the hole.
8.6 Operating enviroment
The FireSAFE unit must not be used in an environment which has been classified as
hazardous where it could provide a source of ignition and therefore cause an explosion by
flame path.
Grundfos do not accept any responsibility for the use of FireSAFE unit to pump liquids which
could be construed as being hazardous to health either by touch, ingestion or inhalation of
fumes or gases given off by the liquid.
8.7 Installation location
Careful consideration must be given to the location of the FireSAFE unit.
The following are minimum requirements:
The FireSAFE unit should ideally be placed in a location where the Control panel LEDs can
readily be seen and the internal buzzer heard without obstruction.
These are primary warning and alarm events and should be available to be observed and
heard. Additional system provision for alerting the inhabitants to the FireSAFE warnings/alarm
must also be made.
The FireSAFE also needs to be protected against the extremes of temperature during a
Fire and during the winter. Provision to maintain the FireSAFE’s operating conditions needs to
be made within the overall system design.
The FireSAFE unit should be sited in a dry, well ventilated, and frost-free position, where
it will not be subjected to extremes of temperature.
The FireSAFE may be located outdoors in a weather, frost and rodent proof enclosure
with adequate ventilation especially during hot weather. All pipe work subject to freezing
conditions must be adequately protected. Alternative system provision must be made for
alerting the inhabitants to the
FireSAFE warnings and alarms.
To enable maintenance and service of the FireSAFE unit to be carried out satisfactorily,
the area should have adequate lighting for this work to be carried out safely.
