FIGURE 10. INSTALLATION (D2 RECESSED ESCUTCHEON)
CARE AND MAINTENANCE
The following instructions must be implemented for the maintenance and service of the Model FR-QR.
NOTES
Wet pipe sprinkler systems must be maintained at a minimum temperature of 40°F / 4°C to prevent freezing and
bursting of the pipe and/or sprinklers.
Automatic sprinklers are not to be tested with a heat source. Operation of the heat responsive element can result.
Absence of the Outer Ring from the D1 or D2 Recessed Escutcheon, which is used to cover the clearance hole, can
delay sprinkler operation in a fire situation.
In preparation for maintenance of the fire protection system, permission to close the main control valve must be
obtained from the proper authorities, and all affected parties by this action, and must be informed before the
maintenance session can commence.
Do NOT enclose any sprinklers within drapes, curtains, or valances.
Do NOT hang anything from the sprinklers.
Do NOT clean the sprinklers with soap and/or water, detergents, ammonia, cleaning fluids, or other chemicals.
Remove dust, lint, cobwebs, cocoons, insects, and larvae by gently brushing with a feather duster or gently
vacuuming with a soft bristle (i.e., dusting) brush attachment.
Exercise suitable safety precautions in the use and storage of highly flammable materials. The rapid rate of fire
development and spread of these materials can reduce the ability of the sprinkler system to aid in the control of a fire
involving such hazards.
