GW Sprinkler Loflow K15 Series Manual

GW LOFLOW K-15 TYPE C, O & S

Maritime Installation of LOFLOW K15 Sprinklers:

Loflow K15 Sprinklers must be installed in the pendant position. Systems must be designed and installed in
accordance with SOLAS Regulation II-2/12, with the exception of water densities less than 5 litres/min/m
Sprinkler systems must be hydraulically calculated with the Hazen-Williams formula, to provide the
recommended minimum water pressure on the last nozzle to operate in the system. SOLAS and NFPA 750
require the systems to have standing charge of fresh water.

Installation and Maintenance:

Loflow K15 Sprinklers have a small orifice when compared with traditional sprinklers. To minimise the risk of
blocked sprinkler nozzles during operation, the sprinkler pipes must be flushed with fresh clean water through
each branch pipe end to avoid dirt in pipes before the sprinklers are installed.
Caution:
After the pipes have been flushed and the pipe plug removed, the internal pipe threads must be cleaned for any
sealing materials, before the sprinklers are installed.
The sprinklers must always be installed in the pendant position using the special purpose spanner from GW
Sprinkler A/S.
