6.4 Note! Never let the FIREMIKS run dry without concentrate or
flushing water, this will damage the concentrate pump.
6.4.1
The concentrate pumps can withstand some dry running without damage for
a limited time. Dry running must however never be purposely chosen or relied
upon.
6.4.2 When all concentrate liquid is finished, quickly switch to Flushing with
the Selector valve Dosing / Flushing on the concentrate pump inlet (No.
4 on Flow Chart). Or stop the FIREMIKS altogether by shutting down the
main water flow.
6.5 After operation in a fire:
6.5.1 After use of the unit in a fire, or in a test with large water flows; check the
function according to paragraph 7.5.2
6.5.2 Preventive maintenance measure: when the unit has served in a major fire
and the operator wants to ensure optimum future functioning, it may be
appropriate to change the Vanes in the unit. Contact your distributor or
Firemiks AB for spare parts and instructions.
6.6 Optional Dosing Return Valve.
6.6.1 Some units are equipped with an optional dosing return valve. This valve is
not to be used during regular operation and it should remain with the valve
positioned for dosing into the main water line only. The valve should only be
operated by qualified maintenance personnel for maintenance/testing
purposes. See 4.8 for more information.
6.7 Salt sea water use
The Firemiks may be operated with salt water.
FIREMIKS with the aluminum water motor
must always be flushed with fresh
water after use.
This is to avoid excessive corrosion of the aluminum housing.
The surface treatment has good resistance to corrosion, however with use
scratches into the coating may corrode after prolonged exposure to salt water
and impair correct functioning of the unit.
Also if not flushed with fresh water, crystallizing salt will impair the correct
function of the water motor and the concentrate pump.
FIREMIKS with the
nickel-aluminum bronze and stainless-steel
water motor
must always be flushed with fresh water if the unit is drained after use.
Otherwise, crystallizing salt deposits can possibly impair the correct function of
the water motor and the concentrate pump.
