Use precautions
ELECTRICAL SAFETY-TO PREVENT SERIOUS INJURY AND
DEATH FROM TIPPING:
● The power supply environment of this product must have a good grounding
device, must use a three-core plug, and with a well-grounded three-hole
socket to ensure good grounding of this product.
● Three-phase power supply air compressor, must use three-phase five-core
wire, with good grounding, after the cable is connected, start to check whether
the motor rotation direction is consistent with the direction of the arrow of the
main engine, if the opposite direction of the arrow, please switch the two live
wires, the wire diameter of the cable is different due to the different power and
choose different, Refer to the three phase cable diameter selection table in
Chapter 2 of this manual for specific wire diameter selection.
● Before powering this product, please make sure that the power supply you
provide can meet the input power information marked near the power input
port of this product.
● Do not share the socket with other electrical appliances, in case the voltage
is unstable sometimes, resulting in damage to the product.
● When maintaining/repairing or cleaning the product, please be sure to
unplug the power cord to ensure that the product is completely powered off
before operation.
● Regularly check whether the power cord and power plug are damaged, and
make sure that the power cord is not squeezed by other items.

Installation
STEP1: To prevent collision
and collapse of the machine, fix
the machine to the ground with
foot bolts before use.
STEP2: Install the four air
filters at the air
compressor intake ports
STEP3: Disassemble the screws
fixing the cover shell of the air
pressure switch, remove the cover
shell, connect the external cable to
the air pressure switch, and then
fasten the cover shell again.

Electrical principle chart
Description: The motor is three-phase 220V/60Hz, the motor cable
U1\V1\W1 is connected to the motor terminal on the air pressure switch, and
the external power supply U2\V2\W2 is connected to the gas .
The pressure switch is connected to the external power supply end. The
pressure switch controls the power supply and the power failure of the motor
through the set pressure induction.

MAINTENANCE/ Service
1) The electric oil-free air compressor is oil-free lubrication, and it is strictly
prohibited to fill any lubricating oil.
2) The machine should be used in the process of drainage once every one to
two days, cleaning the noise filter.
3) If the electric oil-free air compressor stops suddenly and cannot be
restarted in a short time (the voltage is normal) during the working process, it
may be because the motor of the air compressor head works for a long time is
overheated, and the motor heat protector automatically disconnects the power
to protect the motor. This is a normal phenomenon. When the temperature
decreases, the compressor will automatically start and continue to work.
4) The electric oil-free air compressor can not start normally, please check
whether the power supply is normal, whether the power plug contact is good,
if these are normal, it may be the motor itself or the control system fault, if you
can not solve it by yourself, please contact our company through the seller for
maintenance.
