The following instructions must be implemented for the maintenance and service of the Model RC-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 a Cover Plate Assembly may delay the response time of the sprinkler in case of a fire.
Install the cover plate assembly properly, as shown in Figure 6. Improper installation of the cover plate assembly may cause
improper operation or non-operation.
If the ceiling is to be repainted after the installation of the Sprinkler, care must be exercised to ensure that the new paint does not
seal off any of the air gap.
Factory painted Cover Plates must not be repainted. They should be replaced, if necessary, by factory painted cover plates. Non-
factory applied paint may adversely delay or prevent sprinkler operation in case of a fire.
Do not pull the Cover Plate. Separation may result.
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.
Leaking or corroded sprinklers must be replaced.
Automatic Sprinklers must be kept in a cool and dry place.
Automatic sprinklers must never be physically altered, such as painted, plated, or coated, once shipped from the factory. If the
sprinklers have been in any way modified, they must be replaced.
Great caution must be applied to prevent damage to the sprinklers at all stages - before, during, and after installation. Damaged
units because of dropping, hitting, over-tightening, or wrench slippage, must be replaced.
When remodeling, such as by adding false beams or light fixtures or changing the location of compartment walls, first verify that
the new construction will not violate the installation requirements of the applicable standards of NFPA. Alter the new construction
and/or the sprinkler system to suit the requirements of this document and the applicable NFPA regulations.
The owner is responsible for the maintenance of the sprinkler system, including inspection and testing of its compliance with
this document, as well as the standards of the National Fire Protection Association (e.g., NFPA 25), and the regulations of any
other authorities having jurisdiction. The owner should direct any questions regarding the above rules and regulations to the
installing contractors or the sprinkler manufacturer. It is recommended that automatic sprinkler systems be inspected, tested,
and maintained by a qualified Inspection Service in accordance with NFPA 25.
When placing an order, please contact a local distributor with the following information (Model Name, Temperature Rating
and Finish).
