Maintenance
Model GFR VELO-ECOH Upright Extended Coverage
Sprinklers should be inspected and the sprinkler system
maintained in accordance with NFPA 25. Do not clean
sprinklers with soap and water, ammonia or any other clean-
ing fluids. Remove dust by using a soft brush or gentle vac-
uuming. Remove any sprinkler that has been painted (other
than factory applied) or damaged in any way. A stock of
spare sprinklers should be maintained to allow quick re-
placement of damaged or operated sprinklers. Prior to
installation, sprinklers should be maintained in the original
cartons and packaging until used to minimize the potential
for damage to sprinklers that would cause improper opera-
tion or non-operation.
