3. SAFETY PRECAUTIONSWARNING!

The pump has been designed for use with pail cans. Do not
use any other containers.

All of the models cannot be used to collect acids and alkalis,which may cause corrosion.

Connect the ground wire to pump’s main body and nozzle,
especially when using the device in hazardous areas and/ortransferring inflammable or explosive liquids. Do not usefire.



The device is already correctly and safely regulated. Do notderegulate it.

DANGER!

Please use a durable pail can with a sturdy brim and outlet.
Not using a proper pail can may result in container ’sdeformation.

For APPQ/APPQO models use a compressor of min. 1 HP.
For APPQO300/APPQO400/APPQO-H use a compressor ofmin. 3 HP. For APPQO500/APPQO550 use a compressor ofmin. 5 HP. Optimal pressure is 0.4 ~ 0.6 MPa. Too highpressure may damage the pail can.

Do not collect high temperature objects/liquids (60℃ max).
They may cause deformation of the hose and packing.

When changing the liquid you are going to transfer, always
carefully clean the pump out of the liquid transferred
before. Not doing so may lead to dangerous chemicalreactions.

When the device stops operating or operates in a strange
manner, immediately turn off the device and contact
technical service. Do not use broken equipment, as it may
result in accidents.

CAUTION!

After attaching device’s main body to the pail can, makesure it’s tightly fixed.

The models sucking air release it through the exhaustoutlet. Be careful when standing close to the exhaust outlet.

When the tank becomes full, there is a risk that some of theliquid will leave the system with the exhaust air.

CAUTION!

The device is capable of collecting liquids contaminated bysmall particles of size no larger than 5 mm.

Use a 3/8 air hose or larger. Small hose may be a reason ofpressure reduction.

A strainer is inserted into the air-coupling plug. Dirt may
accumulate on the inner strainer, reducing device’sperformance. Remember to occasionally clean the strainer
with soapy water. The strainer remains in the plug toprotect it against deformation and you should not pull itout. Clean it the way it is.

APPQAS model is originally equipped with an O-Ring madefrom fluoro-rubber. A spare O-Ring made from EPT(Ethylene Propylene Rubber) is included. When willing tocollect corrosive liquids, change the O-Ring to the spare one.
If corrosion still occurs, use an optional, special O-Ring
made from perfluoro-rubber. Also, please refer to permitted
liquids list.

* Please remember, that the safety measures and warnings pointed out in this manual are not exhaustive for all
possible situations. Although we have designed our product to be as safe as possible, persons operating andmaintaining the device should strictly follow all safety rules in the operation/maintenance area.

APPQ Usage Instructions
Product’s state and usage conditions (after delivery):
Pail can/rectangular metal can type: closed can with a 40 mm outlet (not included)
Air regulator’s thread: blue (opening: 1 mm)
Input air pressure: 0.4 ~ 0.6 MPa

How to use it:①

Unfasten the retaining nut and put device’s main body on can’s outlet.

②

Fasten the retaining nut and fix the pump firmly.

③

Connect the air hose while the air valve is closed.

④

Opening the air valve will begin the suction (of a liquid).

⑤Once the can becomes full (pail can: approx. 18 liters; rectangular metal can: approx. 15 liters), thedevice will automatically stop suction.

⑥

After you have finished collecting liquid, close the air valve.

⑦

Disconnect the air hose.

⑧Unfasten the retaining nut and disassemble pump’s main body from the can.

⑨

Cover the can with a dedicated lid.

* At input pressure: 0.4 MPa and below
Air regulator’s thread: change to a red one (opening: 4 mm, INCLUDED)
Pressure regulator’s valve: Please regulate by gradually closing the valve from a fully open state* At input pressure: 0.6 and overAir regulator’s thread: red (opening: 1 mm)
Pressure regulator’s valve: Please regulate by gradually closing the valve from a fully open state

CAUTION!

Pleasebecarefulwhenmanipulating the pressure regulator. Not
paying attention to pressure’s impact may
result in damaging the pail can.

APPQO Usage Instructions

black O-Ring seal.

②

After making sure that the air valve is closed, connect the air hose.

③

Opening the air valve will begin the suction (of a liquid).

④

APPQO 300&500 Usage Instructions
Product’s state and usage conditions (after delivery):
Pail can type: open can (not included)
Input air pressure: 0.4 ~ 0.6 MPa
How to use it:①

Put the device’s main body on the pail can, and make sure that pail can’s brim properly fits to the main body’s
bottom black O-Ring seal.

②

After making sure that the air valve is closed, connect the air hose.

③

Opening the air valve will begin the suction (of a liquid or small particles).
