Transfer Unit Assembly

Tools required but not supplied: Phillips screwdrivers PH1, PH2.
For ease of assembly, Vapotherm recommends the following assembly sequence (“from-the-ground-up”):

Insert the Roll Stand POST into the Roll Stand BASE and fasten (see Roll Stand Installation Guide in Roll Stand box). Return Roll Stand to upright position.
Assemble and install the Media power TM Medical Mobile Power System (battery – Box 2, power supply – Box 3, and remote user interface – in Box 1). Please refer to fully assembled unit .

Assemble brackets onto the Battery and Power Supply. Ensure the metal plates are flush and secure.
Loosen the clamps so they can slide down the Roll Stand pole while attached to the Power Supply and Battery (starting with the Battery)
Ensure at least 1” spacing from the BASE of the stand to the bottom of the Battery. Warning: Not following these spacing requirements may cause damage to the battery.
Tighten the clamp to secure the Battery to the Roll Stand pole (For easier assembly, one assembler can hold the battery while the other tightens)
Slide the Power Supply down on the opposite side of the Battery until the bottom of the clamp reaches the top of the Battery
Tighten the clamp to secure the Power Supply to the Roll Stand pole (For easier assembly, one assembler can hold the Power Supply while the other tightens)
Attach the Front Basket clamps to the basket and loosen clamps.
Slide the basket down the Roll Stand pole until the bottom of the Basket is just above the top of the Power supply.
Tighten the clamps to secure the Basket to the Roll Stand pole.
Attach the Mounting Block Cylinder Holder to E-Cylinder Holder (included in manifold kit) with four screws.
Attach the Mounting Block to the Mounting Block Cylinder Holder with two socket head screws.
Loosen bracket enough so it slides down Roll Stand pole.
Ensure there is a 2” space between the top of the Power Supply and the bottom of the ECylinder Holder.
Tighten the clamp block to secure the ECylinder Holder to the Roll Stand pole (For easier assembly, one assembler can hold the basket while the other tightens). Tighten the screws with the Hex wrench.
Screw the components of the Gas Manifold together so that they are still loose enough to slide down the Roll Stand pole
Ensure the Air side of the Manifold is on the same side as the PF Unit when it is attached
Line up the bottom of the Gas Manifold to the top of the E-Tank Holder and tighten the Gas Manifold to secure the Manifold to the Roll Stand pole (For easier assembly, one assembler can hold the manifold while the other tightens)
Remove the back plate of the Remote User Interface (RUI). Attach the back plate to the third clamp with the supplied screws. Loosen the clamp so it slides down the Roll Stand pole.
Tighten the clamp to secure the Remote User Interface (RUI) to the Roll Stand pole approximately 6 inches from the top of the pole.

Complete the assembly of the Roll Stand, including handle and IV/Device Post (see GCX Roll Stand Installation Guide).
Move the handle assembly to a position 36” (inches) from the top of the Roll Stand. The handle will be towards the front of the Roll Stand.
Attach the 18-inch air hose to the VT Unit connector on the air manifold.
Attach second 18-inch air hose to the Tank connector on the air manifold.
Attach the 10-foot air hose to the Wall connector on the air manifold.
Attach the 18-inch oxygen hose to the VT Unit connector on the oxygen manifold.
Attach second 18-inch oxygen hose to the Tank connector on the oxygen manifold.
Attach the 10-foot oxygen hose to the Wall connector on the oxygen manifold.
Connect the communication cables from the Power Supply to the Battery and from the Power Supply to the Remote User Interface. Use ties to ensure that cables are organized and positioned to prevent disconnection.
Mount the Precision Flow with its base no more than 40” (inches) above the floor.

Warning: To reduce the risk of tipping, the Precision Flow should be mounted on the pole no higher than 40” above the floor (Precision Flow base to floor).

Using the System

Preparation

To run the Precision Flow with wall gas, attach the 10-foot oxygen and air hoses to the wall gas supply.
Before switching from wall to tank gas, make sure that the tanks contain adequate gas supplies.
Allow the power supply to charge fully (reference remote user interface prior to initial use). The power supply should be fully charged before using the VTU for mobile therapy delivery.
Before disconnecting the VTU from line power, make sure that the power supply is turned on.
Before using the system, it is important to confirm there is no leaking from the manifold. Follow the instructions below to leak test the manifold system.

Valve Functionality Test:

To check the functionality of the valves on the manifolds, actuate the brass piece found in the fittings on the air and oxygen manifolds using an Allen wrench or equivalent.
Ensure that after being pressed down, the brass piece returns to its initial position.
If the brass valve does not return to its initial position the manifold should be considered defective and a new one should be used. Call Vapotherm Technical Support

Manifold Leak Test:

After assembly, ensure all hoses are securely connected to the manifold and the Precision Flow
Turn on wall Air while leaving tanks turned off. Listen for any leaking from the manifold connection labeled “Wall” on the Air side
Turn off wall Air and turn on wall Oxygen. Listen for any leaking from the manifold connection labeled “Wall” on the Oxygen side
Turn off wall Oxygen and turn on Air tank. Listen for any leaking from the manifold connection labeled “Tank” on the Air side
Turn off Air tank supply and turn on Oxygen tank supply. Listen for any leaking from the manifold connection labeled “Tank” on the Oxygen side.
Turn on all gas sources and confirm no leaks occur with the manifold fully pressurized
Turn off all supply gasses when manifold is confirmed to have no leaks
If in any step of the testing the manifold is suspected to be leaking, confirm the hoses are securely connected to the manifold. If leaking persists, contact Vapotherm Technical Support. The manifold may be defective and a new one should be shipped to replace the faulty manifold.

Transport Setup

Connect the VT Unit 18-inch air hose to the air (AIR) trap assembly, and the VT Unit 18-inch oxygen hose to the oxygen (O2) trap assembly on the Precision Flow.
Insert the E tanks into the E-tank cylinder holder.
Note: If using oxygen, insert the oxygen E tank on the same side as the oxygen trap on the Precision Flow.
Install the air and O2 E tank regulator:
- Connect the Tank 18-inch oxygen hose to the oxygen E tank.
- Connect the Tank 18-inch air hose to the air E tank.
- Plug the Precision Flow into the Astrodyne-TDI MedipowerTM power supply. Power on the AstrodyneTDI MedipowerTM power supply. Unplug the power cord from the Astrodyne-TDI MedipowerTM power supply to stop charging and store securely on the unit.
