III. Installing Your Air Tank
Locate a secure area close to your air compressor to mount your air tank. The leader hose of the compressor
should be able to reach an available port on the air tank with some slack.
1. Position the tank in its desired location and secure it using standard mounting hardware.
IV. Installing Your Air Tubing & Air Valve
Before cutting any air tubing make sure to double check your measurements. We recommend cutting your
lengths with at least an extra inch per line just to be safe. The Push-To-Connect compression fittings are
reusable but reuse should be kept to a minimum to avoid damage. When threading any fittings make sure to use
Teflon tape or lock-tight to prevent air leaks.
The air valve may be mounted in any direction but it is preferred that it is mounted vertically.
IMPORTANT: Do not rotate or remove the inline check valve in the compressor’s leader hose. Doing so will
damage its seals and will result in damage to your air compressor and voiding of your warranty.
IMPORTANT: Do not make any kinks in your air line. Doing so will disrupt air flow and is irreversible.
Air Compressor to Tank:
[Air Compressor] » [1/4” Leader Hose] » [1/2 to 1/4 NPT Reducer Bushing] » [1/2 NPT F Port] » [Air Tank]
1. Locate a free 1/2 NPT port on your air tank and install a 1/2 to 1/4 NPT reducer bushing using Teflon tape
across the threads.
2. Carefully connect the air compressor leader hose to reducer bushing using Teflon tape on the threading.
When installing the leader hose DO NOT move the inline check valve located just above the swivel fitting.
3. Locate a secure location to mount the leader hose using the bracket provided. Avoid locations where the
leader hose may become tangled with wires and other hoses.
a. When mounting the bracket drill a hole with a 3/16” drill bit and push the self-anchoring hose
bracket into the hole. Route the leader hose through the hose bracket and secure by pressing the
bracket clamp into the locker position.
Pressure Switch in to Tank:
[Air Tank] » [1/2 NPT to 1/8 NPT Reducer Bushing] » [Pressure Switch Unit]
1. Install the 1/2 to 1/8 NPT reducing bushing into an available port on the air tank using Teflon tape on the
threading.
2. Install the pressure switch unit into the reducer bushing again using Teflon tape on the threading.
Train Whistle to Tank:
[Air Tank] » [1/2 to 1/2 NPT Nipple] » [Air Valve] » [1/2” Push-To-Connect Fitting »
[1/2” Air Line] » [1/2” Push-To-Connect Fitting] » [Train Whistle]
1. Plan out the fittings’ placement out before you begin and make sure you understand the correct order.
2. Make sure that your tank is empty of air and that the compressor is not running during installation.
3. Start off by installing the 1/2 to 1/2 NPT nipple fitting in to the side of your air tank using Teflon tape or a
locking compound on its threads.
4. Next install the 1/2” air valve on to exposed side of the 1/2 to 1/2 NPT nipple using Teflon tape or a
locking compound again. Make sure that the arrow on the valve points from the tank outwards towards
where you will connect your whistle. The tank side of the valve should be marked Inlet, the other Outlet.
5. Now you can run air line from your train whistle to the air tank and cut the length required. Make sure
the cut end is flat and the cut is completely perpendicular to the tubing length.
6. Install the air line carefully between the whistle and the air valve making sure not to damage the Push-To-
Connect fittings.
Drain Cock in Tank:
1. Install the drain cock in the 1/4 NPT port on your air tank. If the drain cock has compound on its threads
it is unnecessary to use Teflon tape on the threads.
Extra Ports in Tank:
1. Install the supplied three 1/2 NPT plugs in the remaining 1/2 NPT ports using Teflon tape on the threads.
