Operation of the heat responsive element can result. <br /> Absence of a Cover Plate Assembly may delay the response time of the sprinkler in case of a fire. <br /> Install the cover plate assembly properly, as shown in Figure 6. Improper installation of the cover plate assembly may cause <br /> improper operation or non-operation. <br /> 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 <br /> seal off any of the air gap. <br /> Factory painted Cover Plates must not be repainted.They should be replaced,if necessary,by factory painted cover plates.Non- <br /> factory applied paint may adversely delay or prevent sprinkler operation in case of a fire. <br /> Do not pull the Cover Plate. Separation may result. <br /> In preparation for maintenance of the fire protection system,permission to close the main control valve must be obtained from the <br /> proper authorities,and all affected parties by this action,and must be informed before the maintenance session can commence. <br /> Do NOT enclose any sprinklers within drapes,curtains,or valances. <br /> Do NOT hang anything from the sprinklers. <br /> Do NOT clean the sprinklers with soap and/or water, detergents, ammonia, cleaning fluids, or other chemicals. Remove dust, <br /> lint, cobwebs, cocoons, insects, and larvae by gently brushing with a feather duster or gently vacuuming with a soft bristle(i.e., <br /> dusting)brush attachment. <br /> Exercise suitable safety precautions in the use and storage of highly flammable materials.The rapid rate of fire development and <br /> spread of these materials can reduce the ability of the sprinkler system to aid in the control of a fire involving such hazards. <br /> www.senjusprinkler.com Page 7 of 8 Document No.U085168• 02-08-2021 <br />
