, P/N 15040 System Design Page34-17 3A.4 Vehicle Paint Spray Booths (continued): Temperature Range: The operating temperature range for Vehicle Paint Spray Booth applications is -I0^Fto120"F� 29tto49°C). Piping Requirements: Piping diagrams include limitations on pipe length and fittings. System piping must bebalanced. Balanced piping is that in which the difference between the shortest actual pipe length from any Y4"tee to nozzle and the longest actual pipe length from any Y4"tee to nozzle does not exceed 1O%of the longest actual pipe length from any Y4"tee to nozzle. Piping runs from the 1"tee to each of the Y4"tees must be equal inlength. The number and type of fittings for all tee to nozzle sections must 6eequal. All piping must be Schedule 40, hot-dipped galvanized steel pipe,and all fittings must be 150 lb.class,minimum. Examples of acceptable fitting materials include hot7dippedgalvanized malleable iron, ductile iron,orsteel. Couplings and unions may be used where n ecessary,and reducing bushings or reducing tees can be used for changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive atmospheres. 3A.4.1 Work Area Coverage, VPSB There.are two distinctly different nozzle and piping arrangements for protecting the Work Area using the IS45ABC cylinder. The first arrangement b and the second is"'Module Perimeter Work Area Coverage outlined asfollows: 3A.A.1.1 Staridard The Amerex Vehicle PaintSpray Booth System is flexible enough to protect a wide variety of Vehicle Booths ofvarious dimensions. The maximum booth height isZ3'4". As noted,the |345 cylinderis used with two or four nozzles,and each of the nozzles has been tested to protect a Work Area Module. A Work Area can be thought ofasa series of 'boxes', or Modules, stacked together, each protectedwith a nozzle. The maximum parameters for each Module are given asfollows: y ' 1,U5O ftpernozde two or four TF nozzles per|545ABC Maximum Mod.ule Area: 1O5*2 per nozzle for booths upto1U ft.\nbeigWt;* .4Sft./for booths mt23ft,4in, height:* Maximum Module Height: 23 ft"4in.

Maximum Nozzle Offset—Booth Edge Ent : Entry into the module at the closest point to the intersection mf the booth wall and ceiling. The nozzle location, horizontally, is at the midpoint of the longest side of the module,+/-2 feet, The tip of the nozzle must be within 6"nf its entry point. This option is allowable only for booths 1O feet or less!nheight. ULEKSZOD April 9,Z013
