Summary

Heartland Recreational Vehicles, LLC (Heartland) is recalling certain 2022 Lithium, Prowler, and Trail Runner travel trailers, equipped with a 50-amp shore power inlet.

50 amp Shore Power inlet Inspection / Replacement Instructions

99.01.65

 

***This applies to the 50 Amp model 93379 shore power inlets only***

1. Locate power inlet on the off door side or rear of the unit

2. Remove the four #2 square head screws holding the inlet to the coach.

3. Remove the Two #2 Phillips head screws inside the socket. And slide the cover back on the wire to access the the wire lugs.

4. For the following step you will need a torque screwdriver set to 20 Inch Lbs.

5. See photo below: There are 4 wire lugs on the inlet. You will need to verify the torque of these screws. They need to be tightened to 20 INCH LBS. If proper torque cannot be achieved due to the screw having the improper machining, the inlet must be replaced with a new one. If this is the case continue on to the next step.

6. Loosen the two screws that hold the strain relief tight

7. Open strain relief.

8. Loosen wire lug screws

9. Remove inlet from wires

10. Position the new replacement inlet on to the wires. Making sure the right color wires go where they are supposed to. The holes are color coded Red wire in red hole, black wire in black hole, white wire in white hole, and solid copper in the green hole. (Make sure you do not have any bare copper exposed outside the wire entry holes.)

11. Snug down wire lugs to 20 Inch pounds with screwdriver.

12. Tighten the strain relief

13. Verify the torque of the wire lugs @ 20 INCH LBS with torque screwdriver.

14. Slide the wire cover onto the inlet. There are holes to place retaining screws. Make sure they line up with the screws in the socket.

15. Now tighten the screws in the socket until snug (careful not to strip the screw or hole)

16. Now push the inlet back in to its hole on the coach and install the four #2 square screws and reseal around the inlet if necessary.

17. Replacement is now complete

 

***Tools Needed***

Screwdriver #2 Square head
Screwdriver #2 Phillips
Wire Cutters
Wire strippers
Torque screw driver capable of 20 inch pounds

PRODUCT CONTAINMENT REQUEST

50A Shore Power Inlets (93379)

 

March 15, 2022

 

Dear Valued Customer:

 

We are writing to inform you of a Patrick Industries product containment request. Due to a potential quality issue, we are asking you to contain your inventory of 50A Shore Power Inlets (Part No. 93379) received at your plant between February 2 and February 22, 2022.

 

What is the Problem?

Patrick Distribution was made aware that a number of 50A Shore Power Inlets (93379) manufactured and imported by ZH Brothers International and distributed by Patrick Distribution were not manufactured to specifications. Specifically, the lugs for the inlets in two shipment lots were produced using an excessively hard material that may prevent proper torquing of the lug to the required 20in/lbs.  If the lugs are not properly torqued, they may loosen and cause arching, overheating and, potentially, a fire.

 

Upon consultation with the manufacturer, we determined that the issue was isolated to two (2) recent import shipments, which can be identified by the PO numbers “100P044900” and “100P044934” stamped on the box, as shown here:

 

These parts were received into Patrick Distribution’s stock on February 1 and February 9, 2022 and supplied to you between February 2 and February 22, 2022.

 

What Should You Do?

  • Please check your parts inventory for any remaining parts and return them to Patrick Distribution.  Patrick Industries will cover return freight charges. Again, this action applies only to products with container markings of 100P044900 and 100P044934.
  • For any vehicles on which parts were installed between February 2, 2022 and the date by which your inventory was contained, we recommend that the torque be checked and confirmed as meeting the 20in/lbs. specification. If the lugs are unable to be torqued to 20-in/lbs., the inlet should be removed and replaced with a new inlet. If the lugs are confirmed as meeting the torque specification (20in/lbs.), no further action is necessary. We will reimburse you 0.25 hours for inspection and, if the inlet needs replacing, an additional 0.25 hours for replacement, in accordance with our standard warranty procedure.
  • If vehicles containing the affected inlets have left your control, we recommend that you advise dealers or owners of this issue and arrange to have the inlets inspected for proper torque and, if necessary, replaced on their units. You should also consider any regulatory reporting obligations in connection with this concern.

 

If you have questions, please contact Orrin Price at (574) 612-6271 or priceo@patrickind.com.

 

*             *             *

 

We apologize for the inconvenience this issue may cause.

 

Sincerely,

 

Patrick Distribution
