The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user. Indoor The ideal environment for the storage of fans and accessories is indoors, above grade, in a low humidity atmosphere which is sealed to prevent the entry of blowing dust, rain or snow. Temperatures should be evenly maintained between 30° to 110°F (-1° to 43°C) (wide temperature swings may cause condensation and “sweating” of metal parts). All accessories must be stored indoors in a clean, dry atmosphere. Remove any accumulations of dirt, water, ice or snow and wipe dry before moving to indoor storage. To avoid “sweating” of metal parts allow cold parts to reach room temperature. To dry parts and packages use a portable electric heater to get rid of any moisture buildup. Leave coverings loose to permit air circulation and to allow for periodic inspection. The unit should be stored at least 31/2 in. (89 mm) off the floor on wooden blocks covered with moisture proof paper or polyethylene sheathing. Aisles between parts and along all walls should be provided to permit air circulation and space for inspection. Outdoor Fans designed for outdoor applications may be stored outdoors, if absolutely necessary. Roads or aisles for portable cranes and hauling equipment are needed. The fan should be placed on a level surface to prevent water from leaking into the fan. The fan should be elevated on an adequate number of wooden blocks so that it is above water and snow levels and has enough blocking to prevent it from settling into soft ground. Locate parts far enough apart to permit air circulation, sunlight and space for periodic inspection. To minimize water accumulation, place all fan parts on blocking supports so that rain water will run off. Do not cover parts with plastic film or tarps as these cause condensation of moisture from the air passing through heating and cooling cycles. Fan wheels should be blocked to prevent spinning caused by strong winds. Inspection and Maintenance During Storage While in storage, inspect fans once per month. Keep a record of inspection and maintenance performed. If moisture or dirt accumulations are found on parts, the source should be located and eliminated. At each inspection, rotate the wheel by hand ten to fifteen revolutions to distribute lubricant on motor. If paint deterioration begins, consideration should be given to touch-up or repainting. Fans with special coatings may require special techniques for touch-up or repair. Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lint- free cloths. Polish any remaining rust from surface with crocus cloth or fine emery paper and oil. Do not destroy the continuity of the surfaces. Thoroughly wipe clean with Tectyl® 506 (Ashland Inc.) or the equivalent. For hard to reach internal surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive, WD-40® or the equivalent. Removing From Storage As fans are removed from storage to be installed in their final location, they should be protected and maintained in a similar fashion until the fan equipment goes into operation. 2 Model BDF • Belt Drive Duct Fan ® Chart 1: BDF Fan Dimensions Unit Size A B C D E F G H I J K* Approximate Weight Material ThicknessFan Filter Box 80 231.4 (591) 181.2 (470) 157.8 (403) 153.16 (386) 1211.16 (322) 93.4 (248) 87.8 (225) 1 (25) 53.8 (137) 41.4 (108) 493.4 (1264) 71 (32) 32 (15) 20 gauge (.912 mm) 90 241.4 (616) 211.4 (540) 183.4 (476) 181.4 (464) 157.8 (403) 121.4 (311) 101.2 (267) 1 (25) 63.4 (171) 41.2 (114) 547.8 (1394) 92 (42) 42 (19) 100 261.4 (667) 223.4 (578) 203.4 (527) 193.4 (502) 177.8 (454) 133.4 (349) 117.8 (302) 1 (25) 73.8 (187) 41.2 (114) 517.8 (1318) 107 (49) 52 (24) 120 33 (838) 271.4 (692) 223.4 (578) 241.8 (613) 197.8 (505) 16 (406) 133.8 (340) 1 (25) 77.8 (200) 55.8 (143) 639.16 (1614) 144 (65) 70 (32) 150 343.4 (883) 325.8 (829) 273.4 (705) 285.8 (727) 237.8 (606) 191.8 (486) 163.8 (416) 11.2 (38) 97.8 (251) 63.4 (171) 621.16 (1576) 223 (101) 97 (44) 180 401.4 (1022) 413.4 (1060) 313.4 (806) 371.2 (953) 277.8 (708) 221.2 (572) 187.8 (479) 11.2 (38) 101.2 (267) 95.8 (244) 753.8 (1915) 307 (139) 134 (61) 200 501.4 (1276) 491.4 (1251) 393.4 (1010) 451.8 (1146) 36 (914) 231.8 (587) 251.4 (614) 11.2 (38) 121.2 (318) 13 (330) 851.4 (2165) 565 (256) 174 (79) All dimensions in inches (millimeters) and weight is shown in pounds (kilograms). *May be greater depending on motor. **Weight shown is largest cataloged Open Drip Proof motor.
