1.4 Safety Regulations
Please abide by the safety guide when you operate the machine so as to
prevent damage of the machine and personal injuries.
1.4.1 Safety Signs and Labels
All electrical components should be installed by qualified electricians.
Turn off main switch and control switch during repair and maintenance.
Warning！High voltage！
This mark is attached on the cover of the control box.
Warning！Be careful！
Be more careful when this mark appears.
Attention！
No need for regular inspection because all the electrical parts in
the control unit are fixed tightly！

2. Structure Characteristics and Working Principle
2.1 Working Principle
SAL-700G series are suitable for conveying plastic granules over long distance.
Utilizing high efficiency vacuum blower to produce vacuum in material hopper,
plastic materials will then be fed into material hopper by air pressure.
2.1.1 SAL-700G Working Principle
Hopper SAL-700G
Picture 2-1: Working Principle
1. High-pressure blower 2. Control box
3. Material inlet pipe 4. Storage hopper
5. Materials 6. Detection device
7. Discharging plate

12(25)
Turn on the machine, the high pressure blower(1)starts work, it makes storage
hopper (4) generate the vacuum. Discharging plate(7) closed, materials in silo
get into the storage hopper(3) through material inlet pipe(4) by air pressure.
When the loader finishes the work, high pressure blower(1) stop working,
materials (5) will drop off due to gravity. When the reed switch (7) detects
there’s no material, high pressure blower (1) will start working again. When the
loader can’t suck the matrial or material shortage, the buzzer on control box(2)
will alarm. Table 2-1: Description of detection device

2.2 Accessory
Cyclone dust collector
For SHR,SCH-6U/12U/24U and SICH-6U/12U/24U are optional
(Temperature redution is below 30 within 30min).
SMH can be matched with SCH-12U/24U to facilitate the temporary storage
of materials.
2.3 Options
For folished hopper inside ones,add “P”at the end of the model code.
It is suggested to opt cyclone dust collector to reduce
cleaning times of filter when regrind material occupies
over 30% of total raw material.

3. Installation Layout
3.1 Installation and Positioning
1)
Machine just can be mounted in vertical position. Make sure there’s no
pipe, fixed structure or other objects above the installing location and around
the machine which may block machine’s installation, hit objects or injure
human person.
2) For easy maintenance, it’s suggestedto leave 1m space around the machine.
3) Machine should be placed on water-level surface. If it needs to be mounted
on a higher surface (e.g. the scaffold or the interlayer), should ensure its
structure and size could bear the weight and size of the machine.
3.2 Power Connection
1) Make sure the voltage and frequency of the power source comply with
those indicated on the manufacturer nameplate that attached to the
machine.
2) Power cable and earth connection should conform to your local
regulations.
3) Use independent electrical wires and power switch. Diameter of electrical
wire should not be less than those used in the control box.
4) The power cable connection terminals should be tightened securely.
5) The machine requires 1-phase 2-wire power source, connect the power
lead (L, N) to the live wires, and the earth (PE) to the ground.
6) Power supply requirements:
Main power voltage: +/- 5%
Main power frequency: +/- 2%
7) Please refer to electrical drawing of each model to get the detailed
power supply specifications

3.4 Installation steps of matching hopper
1) Place the SAL-700G machine at a proper position on the ground.
2) Install the material hopper on the top of the hopper dryer and the sensor
hopper onto the plastic injection machine. Connect the signal cord to the
machine SAL-700G.
3) Use the steel wire soft hose, connect the air inlets of the sensor hopper to the
current air inlets of SAL-700G, then connect the material inlets of storage
tank to the vacuum hopper(Usually under the dryer or storage barrel)

Picture 3-5: Optional ACF-1 Installation Layout
When conveying plastics contain dusts in high proportion, optional dust cyclone
separator is recommended to reduce the purging times of main machine filter.
Installation:
1) Locate the mounting hole as shown in Figure 3-6;
2) Remove the bolt;
3) Mount the ACF-1 on coverplate of SAL-G and lock up the screws;
4) Connect the air inlet of ACF-1 with steel wire hose to air inlet of the hopper;
5) Connect one end of steel wire hose to hopper material inlet, and connect to
the suction inlet of storage tank.
