00:00:03.610 I'd like to thank you for purchasing 00:00:05.40000:00:05.410 visible defects visual detection system 00:00:07.79900:00:07.809 for fighting tracked heat exchangers 00:00:09.24000:00:09.250 featuring the contractors crack finder 00:00:11.45900:00:11.469 with a low odor no smoke non-toxic dye 00:00:15.11900:00:15.129 penetrant used to find cracks and heat 00:00:17.76000:00:17.770 exchangers your visual inspection kit 00:00:21.09000:00:21.100 includes our patent-pending spray 00:00:22.92000:00:22.930 applicator to spray nozzles and 00:00:25.35000:00:25.360 inspection mirror safety glasses and a 00:00:28.59000:00:28.600 UV flashlight for detecting the dye i'd 00:00:32.97000:00:32.980 like to demonstrate how to use our 00:00:34.29000:00:34.300 product most heat exchangers have very 00:00:36.75000:00:36.760 limited access to get to the heat 00:00:38.13000:00:38.140 exchanger if the crack is where you 00:00:39.96000:00:39.970 can't view it either from the a coil 00:00:41.34000:00:41.350 access through the blower or maybe 00:00:43.38000:00:43.390 through the insertion limit hole you 00:00:44.70000:00:44.710 have no way of finding any cracks that 00:00:46.44000:00:46.450 might be visible otherwise the visible 00:00:48.99000:00:49.000 defects visual detection system is 00:00:50.76000:00:50.770 especially useful on heat exchangers 00:00:52.31900:00:52.329 where portions of the heat exchanger and 00:00:53.72900:00:53.739 not visible for inspection 00:00:55.61000:00:55.620 serpentine types heat exchangers due to 00:00:58.44000:00:58.450 their shape after you get through the 00:01:01.38000:01:01.390 first pass you cannot do any inspections 00:01:04.00900:01:04.019 whenever you use our product please be 00:01:06.30000:01:06.310 safe always wear your safety glasses 00:01:08.42000:01:08.430 turn off all electrical power to the 00:01:10.62000:01:10.630 unit you're servicing pull the blower 00:01:13.28900:01:13.299 motor and lay down towels around the 00:01:15.84000:01:15.850 perimeter of the blower compartment to 00:01:17.10000:01:17.110 make sure that none of this dye leaks on 00:01:18.87000:01:18.880 mrs. Smith's white carpet it is bright 00:01:20.49000:01:20.500 green the visible defects visual 00:01:23.13000:01:23.140 detection system is sent around our 00:01:25.92000:01:25.930 fluorescent dye penetrant and the spray 00:01:28.80000:01:28.810 bar applicator the spray bar applicator 00:01:31.46900:01:31.479 will go through any hole in a helix in a 00:01:34.85900:01:34.869 furnace cabinet and if there aren't 00:01:37.02000:01:37.030 enough holes you can make your own screw 00:01:38.39900:01:38.409 hole you do this by measuring between 00:01:40.46900:01:40.479 the cells and then transposing those on 00:01:43.14000:01:43.150 the front panel using as your insertion 00:01:46.56000:01:46.570 limit as the point of starting the way 00:01:49.92000:01:49.930 to use this is we take the 11 inch spray 00:01:51.87000:01:51.880 bar we insert it in a screw hole or 00:01:55.59000:01:55.600 through the insertion limit you notice 00:01:57.09000:01:57.100 it'll get about halfway through the heat 00:01:58.32000:01:58.330 exchanger then as we spray it sprays the 00:02:00.69000:02:00.700 holy heat exchanger top to bottom now if 00:02:05.73000:02:05.740 we're in a closet and we don't have 00:02:07.17000:02:07.180 access to the back of the heat exchanger 00:02:09.60000:02:09.610 to insert it from the rear to get the 00:02:11.25000:02:11.260 back half there's a spray nozzle then we 00:02:13.80000:02:13.810 put on the hose and then we can soak 00:02:17.17000:02:17.180 the back of the heat exchanger without 00:02:19.14900:02:19.159 getting access to the back of the 00:02:20.80000:02:20.810 furnace 00:02:21.36000:02:21.370 once you've saturated the air side of 00:02:23.67900:02:23.689 the heat exchanger you want to take your 00:02:25.00000:02:25.010 backlight flashlight and look at the 00:02:26.92000:02:26.930 combustion side of the cells through the 00:02:28.69000:02:28.700 burner openings any evidence of the 00:02:31.44900:02:31.459 green dye penetrating is evidence that 00:02:34.36000:02:34.370 you have a cracker hole that needs 00:02:36.72900:02:36.739 further investigation on some modern 00:02:39.69900:02:39.709 crimp style heat exchangers the dye will 00:02:41.67900:02:41.689 penetrate through this will be a very 00:02:43.24000:02:43.250 minut amount in the seams where the two 00:02:45.64000:02:45.650 halves of the heat exchanger meet this 00:02:47.47000:02:47.480 is normal 00:02:48.28000:02:48.290 any excessive dye or flooding of the 00:02:50.50000:02:50.510 chambers would be indication of a much 00:02:52.42000:02:52.430 serious problem hole or crack 00:02:55.79000:02:55.800 I would always recommend using a camera 00:02:59.12000:02:59.130 to document any cracks you find because 00:03:01.31000:03:01.320 your competitors may not have the same 00:03:03.11000:03:03.120 tools that you have that allowed you to 00:03:04.97000:03:04.980 find these cracks in a camera with the 00:03:07.28000:03:07.290 videotape is really the only way you can 00:03:09.08000:03:09.090 document it to your customer that they 00:03:10.88000:03:10.890 have a problem in a format that they 00:03:12.89000:03:12.900 understand everybody watches TV and if 00:03:15.35000:03:15.360 they see a crack on TV it looks more 00:03:17.51000:03:17.520 like a cracked and trying to have them 00:03:19.31000:03:19.320 bend down and look up inside a small 00:03:20.99000:03:21.000 hole at something they've never seen 00:03:22.79000:03:22.800 before so I would always recommend using 00:03:24.86000:03:24.870 a camera you can use ours or use 00:03:26.90000:03:26.910 somebody else's but always document 00:03:28.64000:03:28.650 cracks you find it's for your own 00:03:29.99000:03:30.000 protection I'd like to take this 00:03:32.27000:03:32.280 opportunity to thank you for investing 00:03:34.10000:03:34.110 in visible defects visible detection 00:03:36.20000:03:36.210 system
