A damper actuator, installed in an unconditiot_ed space_ can experience co_densadon if its surface temperature f_!l_ below the dewpoint of the surrounding air. Repeated condensation can cause meting of metal parts and e'ver_tualseizir_g of the actuator. The Damper Actuator Protective Cover is placed over the actuator and over the duct insulation. It is taped onto the duct insulation, forming a sealed vapor barrier around the actuator that will help prevent, condertsation on the actuator surface and internal parts. This cover is a one size fits all design. It ca_ be wrapped around a round style damper as small as 6" in diameter or can be used on the flat surface of a rectangular style damper. It is made of Lexan, an extremely tough material. Under nortual circumstances, you can bend, wrinkle, or fold it and it will not csack or bre_. It will withstand temperatures from -40 ° F t_300 ° F. HOW IT WORKS This cover is a vapor barrier and at the same tit_xe,it is a poor therma! insulator, This allows the actuator to be slightly warmed by the surrounding exter_aI air, tuaking it warmer than the duct surface under the insulation. Any water vapor trapped under the cover or underthe duct insulation is conder_sed on the coldest surface, wNch is the duct itself. The actuator, just slightly w_trmer, experiences no condensation. The outside surface of the cover may condense, but the inside wiI1 stay dry. .The posidve pressure inside the duct tends to expel air, through duct leakage, into the space under the insulation and the cowr. This means air will flow OUT ar_y leaks rather than in, blocking inward, moisture flow from the atubient at,ca. INSTALLATION NOTE: Ensure proper damper wiring alad operation before installing cover, Once actuator is covered, it may r_ot be easily serviced or accessed. Lay the cover over the actuator so that it overlaps the duct ir_sulation on all sides. Route the actuator wire down the wiring channel provided, and tape all four sides down to the duct i_sulation, using common duct tape. See Fig, 1, It is best if the duct insulation is not sealed around the actuator, allowing the air space under the insulation to be con,tooted to the air space m_der the cover. An additional layer of insulation may be applied over the entire actuator and cover, if desired. Be sure to use. flexible it_sulaLion,contaloiog a vapor barrier. This layer will reduce coning losses and lessen tl_e ch_.ce of coJ_densation on the outside of Ne cover. Form; IM-DAMP-09 Cancels: NEW Printed in U,S,A, 1+00 Catalog No. 68DA-MP5 ........
