Maintenance

Model GL112 QR Sprinklers should be inspected and

the sprinkler system maintained in accordance with NFPA

25. Do not clean sprinklers with soap and water, ammo-

nia or any other cleaning fluids. Remove dust by using

a soft brush or gentle vacuuming. Remove any sprinkler

which has been painted (other than factory applied) or

damaged in any way. A stock of spare sprinklers should

be maintained to allow quick replacement 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 operation or non-operation.
