Intended Use
The Vapotherm Transfer Unit (VTU) allows the mobile delivery of high-flow humidified respiratory therapy within a
hospital environment. With a fully charged battery module and full gas cylinders, the length of available mobile
therapy depends on 2 factors:
Cylinder gas supply: From 14 minutes to 18.7 hours, based on the O2/air gas ratio and flow rate settings
on the Precision Flow.
Battery life: Up to 1.5 hours from a full charge.
o Tripp Lite recommends that the Power Supply be plugged into a wall outlet, charging the battery as
often as possible. Charging the batteries for brief intervals DOES NOT adversely affect battery
performance. However, leaving the batteries fully discharged for long periods of time DOES
adversely affect battery performance.
o For long term storage, the battery should be fully charged at a minimum of once per month.
The VTU consists of the

For ease of assembly and to avoid injury when handling the heavy power components, the VTU should be assembled
by a minimum of 2 trained professionals.
Only the Tripp-Lite Medical-Grade Mobile Power Retrofit Kit, model HCRK-36, has been validated for use with the
Vapotherm Precision Flow. Using a power supply not validated by Vapotherm for use with the Precision Flow may
result in inadequate device performance. Battery should be fully charged once a month at a minimum.
Before assembly and use of the system, please refer to the following indications, warnings and cautions:
Vapotherm Precision Flow: Indications, Warnings and Cautions, as published in the Precision Flow Operating
Instruction Manual.
Tripp Lite Medical-Grade Mobile Power Retrofit Kit: Important Safety Instructions, as published in the
Owner’s Manual.
To understand the alarm behavior of the system, please refer to the description of alarms in the following
documentation:
Vapotherm Precision Flow Operating Instruction Manual

Using the System
Preparation
To run the Precision Flow with wall gas across its full operational range, attach the 10-foot oxygen and air
hoses to a minimum of 40-psi gas supply.
Before switching from wall to tank gas, make sure that the E-cylinders contain adequate gas supplies (2000
psi).
Allow the power supply to charge for 24 hours 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. This is
indicated by 5 LEDs on the power supply Remote User Interface.
Transfer Setup
1. Connect the yellow VT UNIT 3-foot air hose to the air trap (AIR), and the green VT UNIT 3-foot oxygen hose
to the oxygen (O2) trap on the Precision Flow.
2. Plug the Precision Flow into the medical grade mobile power supply.
3. Insert the oxygen E cylinder into the dual cylinder holder.
Repeat for the compressed air E Cylinder.
Note: Insert the oxygen E Cylinder on the same side as the oxygen trap on the Precision Flow.
4. Install the air and oxygen E Cylinders:
Connect the oxygen TANK 3-foot oxygen hose to the oxygen E cylinder.
Connect the air TANK 3-foot air hose to the air E cylinder.
5. Power on the medical grade mobile power supply.
Switching Gas and Power Sources
1. Confirm the Precision Flow therapy settings.
2. Open the oxygen and air E cylinders and confirm that the cylinders contain adequate gas supply.
Warning: Do not attempt to transfer a patient with ≤ 400 psi in either tank.
3. Disconnect the oxygen and air hoses from the wall gas supply.
4. Unplug the power cord from the medical grade mobile power supply and store securely on the unit.
Warning: Make sure the power cord does not drag on the floor and present a tripping hazard. Place the
power cord into the VTU roll stand basket.
5. Transfer patient to desired location within the hospital.
3100563 Rev. B 19
Page 20
6. At destination
Connect the oxygen and air hoses to the wall gas supply,
Plug the medical grade mobile power supply into a hospital-grade outlet.
Close the E cylinders once connected to a wall gas supply.
Note: When the VTU is stationary, lock the wheels of the PF Roll Stand.
Warning: If the Precision Flow continuously sounds a gas alarm, confirm that all connections to the gas supply (wall
or tank) are correct or that there is adequate gas supply in the tanks. Refer to the Precision Flow Operating
Instruction Manual for detailed information about the Precision Flow’s alarm behavior.

Warning: These mobile run time estimates are based on use of a 2000-psi E cylinder. Actual performance may vary
depending on the amount of gas in the cylinders.
The Vapotherm Transfer Unit (VTU) allows the mobile delivery of high-flow humidified respiratory therapy within a
hospital environment. With a fully charged battery module and full gas cylinders, the length of available mobile
therapy depends on 2 factors:
Cylinder gas supply: From 14 minutes to 18.7 hours, based on the O2/air gas ratio and flow rate settings
on the Precision Flow.
Battery life: Up to 1.5 hours from a full charge.
