6.2.1 Application limits
NOTE
On-site conditions deviating from the test conditions may have a negative impact
on the operating reliability. Regardless of the effective volume of the tank, the
operating reliability of the system must be checked in an on-site acceptance
inspection in accordance with DIN 14462.
The effective volume of the tank is selected to DIN 1988-500 as standard. Mains
water is refilled via a float valve.
To ensure a sufficient supply of fire-fighting water and when using a tank with
reduced effective volume observe the following application limits:
