H2 V2S Lite Lite Extruder
Product Information
The H2 V2S Lite is a product from the H2 series of products. It
should be noted that this product is not compatible with standard
NEMA14 motor. The dimensions of the product (including the fan) are
72.1 x 37.9 x 80.6mm. The thread of the nozzle/heat break is M4 and
the nozzle diameter is 0.6mm. The product has a maximum operating
temperature, which is the maximum working temperature of a single
part and not of the whole system. The heater cartridge
specifications include a head size of 6 x 20mm, voltage of 24V and
power of 70W. The fan specifications include an item size of 35 x
35 x 10mm, cable length of 150mm, voltage of 24V and speed of
Terminal Model.
Product Usage Instructions
- Mounting: There are 10pcs M3 screw holes on the extruder for
fixing. The M3X8 screws provided are suitable for mounting plates
with a thickness of 3~5mm. It is recommended to install the fan
towards the left. If installed towards the right, pay attention to
the gear and air vent. - Filament Tension and Filament Release: The drive gear tension
is adjustable to accommodate different material filament. Turn the
Tensioner Screw counterclockwise to increase pressure and clockwise
to decrease pressure. Do not force it when the screw stops turning
or you will damage the extruder.

H2 V2S Lite vs Other H2 Series Products
Light weight as low as 175g; Flowrate boosted from 15mm³/s to 45mm³/s; The idler arm is made of 7075 T6 aluminum, with special blend high-performance anti-wear MoS2 grease to improve the quick release lever haptics and enhance wear resistance; High performance thermal grease has been pre-applied to the heat break to increase thermal conductivity between the heat break and heatsink to improve cooling performance; The filament drive gear is made of tool steel plated with nano-coating to improve hardness, wear resistance, corrosion resistance and provides longer life when printing abrasive materials.
Note: Not compatible with standard NEMA14 motor.

More Guidance
It is recommended to install the fan toward the left; if toward the right, pay attention to the gear and air vent. There are 10pcs M3 screw holes on the extruder for fixing.
The M3X8 screws provided are suitable for mounting plates with a thickness of 3~5mm.
Please assemble the hotend with the following steps: 1. Insert the heater cartridge into the heater block; 2. Install the heat break; 3. Place the thermistor head into the designated spot on the side of the heater block(preferably pack the spot full of thermal grease, standard thermal grease for PC cooling purposes should suffice)and clamp down the thermistor wire with the included M2 screw and washer; 4. Wrap the heater block with the included PTFE tape at least 3 times for optimal thermal insulation(To achieve the ultimate lightweight and smallest dimension, the thermistor screw and washer can be neglected, fix the thermistor in place with only PTFE tape); 5. Install the nozzle(the nozzle should be hot tightened again after the heater block has been heated to printing temperature).

About Filament Tension and Filament Release
Drive gear tension is adjustable to accommodate different material filament, turn the Tensioner Screw counterclockwise to increase pressure, clockwise to decrease pressure(when the screw stops turning, Do not force it or you will damage the extruder.)
To release the filament, pull the lever towards the position of ç in the picture below.
