IMPORTANT SAFETY MESSAGE
May 17, 2019
IMPORTANT SAFETY RECALL
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Dear Valued Customer:
As you may recall, on March 22, 2019, Carrier Transicold notified you that it had determined that a defect that relates to motor vehicle safety exists in “ComfortPro” standalone auxiliary power unit (APU) models 210STA and PC6112. That defect resulted from the use of a second power supply harness option that is not protected by a ground fault circuit interrupter (“GFCI”) connector. Carrier Transicold has now determined that a second defect related to motor vehicle safety also exists in the ComfortPro branded standalone APU models 210STA and PC6112 because the second power supply harness option is also not protected by an arc fault circuit interrupter (“AFCI”). The affected models were manufactured between June 2012 and March 2019 in the following serial number ranges (together, the “affected APUs”).
|Manufacturing Location||Kitchener, ON||Athens, GA||Athens, GA|
|Starting Serial Number||ETD22204662||SVV91533928||TVB91554548|
|Ending Serial Number||ETD22228719||TVA91551985||TVL91591079|
Our records indicate that affected APUs are registered to your company under the serial number(s) listed in the attachment to this letter.
As previously indicated, the affected APUs make use of a second power supply harness that is not protected by a GFCI. Without the use of a GFCI connector, there is a potential for an electrical short to occur which could put an individual operator/technician at risk of electric shock. For this risk to be observed the affected APUs’ second power supply harness would need to be compromised or damaged during use and then the individual would need to touch or otherwise come into contact with the damaged harness.
In addition, because the affected APUs’ second power supply harness is not protected by an AFCI, if water enters, resulting in severe corrosion where the harness’s connector plugs into the inlet that is connected to the truck’s engine, under certain conditions electrical arcing leading to a fire can occur.
Beginning in mid- to late June 2019 your authorized Carrier Transicold dealer will contact you to arrange to have all affected APUs shown in the attachment to this letter or otherwise in your possession inspected. During that inspection the dealer will, at your option, either (1.) add a combination GFCI and AFCI receptacle to the affected APUs second power supply harness, or (2.) completely remove the second power supply harness from the affected APU. The inspection and addition of the GFCI and AFCI receptacle or removal of the second power supply harness option will be provided at no charge to you.
Carrier Transicold dealers have also received notice that the defects are present and that the GFCI and AFCI receptacle should be added or the second power supply harness option removed. If your Carrier Transicold dealer has already completed this inspection and addition of the GFCI and AFCI receptacle or removed the second power supply harness option in accordance with this notice, no further action is required. If you are unsure whether this occurred, please confirm with your dealer as soon as possible. Should you need help in locating an authorized Carrier Transicold dealer in your area or have any questions, please call the Carrier Transicold Action Line at 800-448-1661.
Federal law requires any lessor who receives a notification of a determination of a safetyrelated defect or noncompliance pertaining to any leased motor vehicle shall send the notice to the lessee within 10 days.
If you believe that Carrier Transicold has failed to remedy the defect without charge, or if you believe that Carrier Transicold has failed to remedy the defect (without charge) within sixty (60) days of your first attempt to obtain the repair, you may submit a complaint to the Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Avenue SE, Washington, DC 20590, or call the toll-free Vehicle Safety Hotline at 1-888-327-4236 (TTY: 1800-424-9153), or go to http://www.safercar.gov.

Scope of Work
This instruction is intended to provide the dealer with the information necessary to perform one of three rework procedures for ComfortPro Stand-Alone APUs (listed in Table 1) equipped with the second power supply harness (also referred to as a ”block heater cable”). The appropriate procedure should be selected based on customer utilization of the block heater cable feature. The three options are as follows:
1. Inspect the APU to verify that the block heater cable assembly and circuit breaker has previously been removed as outlined in this document.
2. Remove the block heater cable assembly and circuit breaker.
3. Retrofit the APU with an AFCI/GFCI receptacle device (referred to as the “device”) in place of the original block heater cable assembly.
Refer to figure 1 for the typical routing of the block heater cable before the retrofit is performed. Figure 2 illustrates the new routing of the cable from the APU to the AFCI/GFCI device, and from the AFCI/GFCI device to the block heater receptacle.

8. Remove the two bolts securing the 15 amp breaker to the breaker bracket. Discard the breaker and attached jumper wire.
9. Reinstall the upper APU enclosure and radiator enclosure cover.
10. Remove the remaining liquid tight conduit and block heater cable from the truck. Install new wire ties if any were cut to remove the conduit/cable.
AFCI/GFCI Retrofit (Option 3)
Customer utilizes the Stand-Alone APU block heater option and wishes to retain the feature. Perform AFCI/GFCI retrofit as follows:
1. Determine the appropriate location for mounting the AFCI/GFCI device.
Note: The device must be mounted inside the cab of the truck in a location that is not subject to weather or physical damage. The location must be accessible and allow sufficient clearance for the operator in the event the device trips. Under the bunk or near the existing hotel power outlet are acceptable locations.
2. Inspect the underside of the cab of the truck to verify there are no structural members, wiring harnesses, or hoses directly under the bunk. A 1-3/4” hole will need to be drilled in the cab floor in a later step. Refer to figure 5.
98-50402-00 REV A 6/11/2019 Page 4
Figure 5. Inspect underside of cab before drilling
3. Apply PVC cement to the outside diameter of the smooth section of both of strain relief connector body. Insert the connector body into the holes in the receptacle box. The box will be mounted later.
4. Drill a 1-3/4” hole in the floor of the truck under the bunk. The hole must be centered below where the receptacle box will be mounted. If the receptacle box will be mounted outside the bunk determine an appropriate location under the bunk to drill the hole.
5. Remove the existing APU block heater cable and route to the hole that was drilled in the floor. The existing cable connector will need to be cut off for the cable to fit into the hole.
6. Determine the length of conduit needed so that at least 6” of the conduit is inside the cab. Allow additional length under the cab for movement.
7. Cut the liquid-tight conduit to length but do not cut the inner cable. See figure 6 and 7.
a) Score the plastic covering at the desired location
b) Bend the conduit back and forth several times to separate the inner sheath.
c) Cut the inner sheath with metal snips. The cut must be even and free of burrs or sharp edges.
Figure 6. Conduit sheath separated
Figure 7. Conduit trimmed to length and free of sharp edges
8. Mount the receptacle box with supplied self-tapping screws. The box must be positioned so the strain reliefs are facing down.
9. (Receptacle box mounted outside bunk only)
Drill two 7/16” holes below the receptacle box and centered under the two strain reliefs at the bottom of the receptacle box. Refer to figure 18. Insert the supplied grommets into the holes.
10. Route the inner cable to the location of the receptacle box. Pass the cable through the bottom of the receptacle box and cut to length allowing at least 5” of cable to extend out of the box. See figure 8.
