4. The XPV should be almost fully charged upon deliv-
ery from Protovapor. It can be used immediately.
General operation
1. Attach atomizer device containing e-liquid to the con-
nector at the top of the unit. DO NOT OVERTIGHTEN!
2. To wake the device from power off state, tap the
Fire button.
3.. Adjust temperature and wattage as described below.
4. Depress firing button and hold while drawing on the
atomizer device.
DNA 40D INFORMATION
Your XPV is powered by the DNA 40D board by Evolv
Vapor.
Temperature Protection
The DNA 40D is the first power supply for electronic
cigarettes to directly measure and limit the temperature
of the heating coil during operation. By preventing the
coil from becoming too hot regardless of fluid, wicking or
airflow, a variety of undesirable situations can be pre-
vented. For example, appropriate temperature settings
will prevent the wicking material from charring, which
compromises taste and introduces unintended chemi-
cals into the vapor. Appropriate temperature settings
will also reduce the breakdown of flavoring and base
liquid components, which could impact taste or safety.
Evolv’s Temperature Protection Technology requires
a heating coil made from Nickel 200 alloy, rather than
Nickel Chromium or Kanthal alloys. Nickel 200 is com-
mercially pure nickel. It is often sold in vapor shops
and online as “non-resistance wire.” If the temperature
reaches the maximum value, the wattage applied to the
atomizer coil is reduced to prevent overheating. Please
note that the temperature reading is the average tem-
perature of the atomizer coil, and care should be taken
to construct the heating coil so that the temperature is
uniform, without hot or cold spots. Ensure that the coil
does not short to itself.
Because wattage, not temperature, controls vapor
volume, large vapor volumes can be produced without
unnecessarily high temperatures. Temperature Protec-
tion is most helpful if the atomizer begins to dry out,
the user pauses during a puff, the beginning or end of
the puff, or if the wattage setting is inappropriate for
the attached atomizer.
In normal operation, when the device is not firing the
maximum temperature setting is displayed on the
screen. When the device is firing, the actual average
temperature of the coil is displayed on the screen.
By default, the Temperature Protection setting is 450°
Fahrenheit. To change the limit:
1) Lock the device by pressing the Fire button five
times.
2) Push the UP/DOWN switch in for two seconds.
3) After two seconds, the maximum temperature will
be displayed, and the UP/DOWN switch should be
released.
4) Use the UP/DOWN switch to adjust the maximum
temperature
5) When the display shows the desired maximum
temperature, press the Fire button to exit temperature
adjust mode.
The maximum temperature is adjustable between 200°
Fahrenheit and 600° Fahrenheit. To disable the tem-
perature protection entirely, adjust the limit up to 600
degrees, then press UP one additional time. The tem-
perature limit will read OFF. This will also disable the
prompt when a new atomizer is attached.
Preheat
When the DNA 40D is used with a temperature sens-
ing atomizer, an additional feature called Preheat is
activated. No vapor is produced when the temperature
is below the boiling point of the liquid. Preheat applies
extra power until the heating coil is up to operating
temperature to shorten the delay between pressing the
fire button and generating vapor. Because the preheat
is temperature based, it will not overheat or burn the
vapor.
Attaching a New Atomizer
The DNA 40D uses the resistance of the atomizer to
calculate the temperature of the heating coil. It continu-
ally looks to see whether a new or changed atomizer
has been connected. If you are using temperature
protection,
be careful to only attach new atomizers
that have cooled to room temperature to the device.
If a new atomizer is attached to the DNA 40D before
it has cooled down, the temperature may read and pro-
tect incorrectly until the new atomizer cools.
When you connect a new atomizer or disconnect and
reconnect your existing atomizer, the DNA 40D will
prompt you to confirm this change. When you fire the
first time, before activating the DNA 40D will prompt
