SEOCONTENT-START

1000 Corporate Centre Drive ▪ Suite 300 Franklin, TN 37067 ▪ Phone: 615-370-3833 www.manchestertank.com June 29, 2022 Dear Valued Customer, We recently discovered that a small number of RegO service valves on recreational vehicle tanks have some short threads in the POL outlets. The short threads do not allow the POL connector to fully seat. This may result in a leak at the connection. The included safety bulletin from RegO outlines the issue, details how to check for the issue and how to remedy the issue. Manchester will assist in any way we can if a valve needs to be replaced. For further information, you may contact RegO at the address on the included document, or Frank Lane at frank.lane@mantank.com or Bob Mangas at bob.mangas@mantank.com or Jared Shutwell at jared.shutwell@mantank.com Thank you, Frank Lane V-P Product Safety Manchester Tank Field Safety Advisory RegO Model 901C Service Valves 06/27/2022 RegO has become aware of a potential issue with the female POL threads on a limited number of RegO model 901C3 and model 901C5 service valves. In some instances, the thread depth of the POL outlet is less than specification, which could result in a leak of propane. Potentially affected valves would have been installed in a limited number of Manchester Tank branded RV tanks dated 2021 and 2022. THIS COULD RESULT IN A FIRE OR EXPLOSION AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH. Which Valves May Be Affected? The affected valves have manufacturing date codes between 02X21 and 02X22. The ‘X’ represents any letter between A through E, which denotes the week of the month the valve was assembled. The date code is marked on a wrench flat. Below is a key to reading the date codes marked on the wrench flat of the valve and their locations. (See Figure 1.) Figure 1: Model Number and Date Code Examples What Should Be Done? Contact a professional to locate the service valve on the container to inspect the model number and date code to determine whether the valve is in scope. If the date Date Code and Model Number Location (Flats) Valve Outlet Connection (POL Threads) code does not fall within the specified range, no further action is required. If the date code falls within the specified range, then follow the instructions below, depending on whether anything is installed in the outlet of the valve and whether there is container pressure. WARNING: FAILURE TO FOLLOW THESE STEPS AND REMOVE FROM SERVICE ANY CONTAINER THAT CONTAINS A LEAKING SERVICE VALVE COULD RESULT IN A FIRE OR EXPLOSION AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH. WARNING: IF YOU ARE NOT A PROPERLY TRAINED LP-GAS PROFESSIONAL, DO NOT ATTEMPT ANY OF THE STEPS OUTLINED BELOW, OR TO OTHERWISE INSPECT, TEST OR ALTER THE SERVICE VALVE ASSEMBLY. ATTEMPTING TO DO SO WITHOUT THE PROPER TRAINING COULD RESULT IN A FIRE OR EXPLOSION, AND SERIOUS PERSONAL INJURY, PROPERTY DAMAGE, OR BOTH. 1. If nothing is installed in the outlet of the valve: a. Use the supplied go/no-go gauge POL nut to determine if the threads are the proper depth. (See Figure 2.) If the threads are not the proper depth, securely close the valve, remove the container from service, and replace the valve. Do not use the container without first replacing the valve. Figure 2: Go/No Go Gauge POL Nut – Groove Cut Through Roll Stamp Information Go/No Go gauge Finger Tight No Visible Groove = Good Part Go/No Go gauge Finger Tight = Needs Replacement Visible Groove = Bad Part b. Alternatively, close the service valve and attach a POL connector to the service valve outlet with an air fitting installed on the ¼” NPT threads. (See Figure 3.) i. Apply 50-100 psi air pressure back towards the outlet of the valve; ii. Use a leak detection solution to determine if this connection is leak tight; iii. If the connection is not leak-tight, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance. Do not use the container without first replacing the valve. Figure 3: POL Connector for Air Test 2. If a POL connector is installed in the outlet of the valve and there is no container pressure: a. Remove the POL connector from the outlet of the service valve and use the supplied go/no-go gauge POL nut to determine if the service valve threads are the proper depth. (See Figure 2). i. If the threads are the proper depth, no further action is required. ii. If the threads are not the proper depth, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance. b.

POL connector POL threads POL connector ¼” NPT threads 3. If a POL connector is installed in the outlet of the valve and there is propane pressure in the container: a. If the service valve is open (and the entire propane system is pressurized), use a leak detection solution at the valve outlet connection. i. If no leaks are observed, no further action required. ii. If a leak is observed at this valve outlet connection and tightening the connection does not stop the leak, close the service valve and contact your OEM, distributor, or dealer for further guidance. b. If the service valve is closed: i. Remove the POL connector from the outlet of the service valve and use the supplied go/no-go gauge POL nut to determine if the service valve threads are the proper depth. (See Figure 2 above.) 1. If the threads are the proper depth, no further action is required. 2. If the threads are not the proper depth, securely close the valve, remove the container from service, and contact your OEM, distributor, or dealer for further guidance. ii.
