Month Date Year Customer Name Address City, State, Zip Bowlus VIN xxxxxx Subject: NHTSA RECALL 22V601 for Manchester Tank & Equipment Co. Propane Tanks NHTSA Recall No. 22V601 This notice applies to your vehicle, [VIN]. This notice is sent to you in accordance with the requirements for the National Highway Traffic and Motor Vehicle Safety Act. Manchester Tank has identified a defect, which relates to motor vehicle safety, in certain Bowlus travel trailers equipped with a Manchester Tank & Equipment Co. Propane Tank. Our records indicate that the propane tank installed in your Bowlus is affected by the recall. We sincerely apologize for the inconvenience, and Manchester Tank & Equipment Co. will provide a remedy for this recall. The Problem The POL valve may have female threads that are less than specification and may leak gas. This output connection could leak propane resulting in a risk of fire or explosion. What Manchester Tank & Equipment Co. will do: The POL valves on all tanks are to be checked with a GO/NO GO gauge to determine if the female thread depth is correct. Then if the tank is in service and already pressurized with propane, a leak test is to be performed by opening the service valve and checking the connection for a leak with a leak detection solution. If the tank is not pressurized, then the output of the POL valve is to be checked by applying an air back pressure of 50 – 100 psi to the output side of the valve and checked with a leak detection solution. This should take approximately 15 minutes. The inspection will be performed at no cost to the owner. Service centers who perform the inspection will be reimbursed by the tank manufacturer for their expense to perform this inspection. If any defective valves are discovered, the valves will be replaced at no cost to the owner. The replacement valve will be supplied at no charge to the service center and the service center’s installation costs will be reimbursed by the tank manufacturer. If replacing the valve does not resolve the leak, or if the valve cannot be replaced, a new tank will be supplied to the service center and the service center’s installation costs will be reimbursed by the tank manufacturer. What You Need to Do: Your options for having the propane tank evaluated and valve or tank replaced (if applicable) are as follows: 1) You may schedule a service appointment with us at our facility in Oxnard, CA, and we will inspect the valve of the tank. The inspection will take approximately 15 minutes. If the valve needs to be replaced, this process will take longer. If this is your preferred path, please let us know which days work best for you for an appointment. We would need your Bowlus to stay with us for up to two business days, and our Service Department is open Monday – Friday from 8:30am – 4:00pm. 2) We can assist in finding a Manchester Tank & Equipment Co.-approved RV Service Center in your area who is able to complete the inspection and valve or tank replacement (if applicable) – also at no charge to you.
