WARNING
Turn off power before service
Risk of electrical shock. Be sure to turn off power to stop the pump
and related devices before service is performed.
Stop operation
If you notice any abnormal or dangerous conditions, suspend op-
eration immediately and inspect/solve problems.
Do not use the pump in any condition other than its intended
purpose
The use of the pump in any conditions other than those clearly
specied may result in failure or injury. Use this product in a speci-
ed conditions only.
Do not modify the pump
Alterations to the pump carries a high degree of risk. It is not the
manufacturer's responsibility for any failure or injury resulting from
alternations to the pump.

Prohibited
Do not remodel
Use specied power only
Do not apply power other than that specied on the nameplate.
Otherwise, failure or re may result. Ensure the pump is properly
grounded.
Wear protective clothing
Always wear protective clothing such as an eye protection, chemi-
cal resistant gloves, a mask and a face shield during disassembly,
assembly or maintenance work. The specic solution will dictate the
degree of protection. Refer to MSDS precautions from the solution
supplier.
Do not damage a power cable
Do not pull, knot or crush the power cable. Damage to the power
cable could lead to a re or electrical shock if cut or broken.

Precautions for use
• Electrical work should be performed by a qualied
electrician. Otherwise, personal injury or property
damage may result.
• Do not install the pump in a place where the pump
can get wet. Avoid using wet gas, or internal con-
densation will build up and consequently result in
the short lives of the valve and diaphragm.
• Do not use the pump in a dusty place. Be sure
to provide the inlet with a filter to prevent foreign
matters from getting into the pump. Otherwise, the
pump performance may reduce or the lives of the
valve and diaphragm remarkably shorten.
Safety instructions
Caution
• Do not install the pump in a corrosive or flamma-
ble gas atmosphere. Keep good ventilation in a
working area. Ambient temperature should not fall
below 5°C or exceed 40°C. Observe the allowable
gas temperature range of 0 and 40°C.
• If the compressed air (higher pressure than atmos-
pheric pressure) is transferred to the pump, sharp
deterioration to the lives of the valve, diaphragm
and bearing may result. Always keep atmospheric
or lower pressure in the suction line.
Do not increase suc-
tion line pressure
Precautions for use
9
Page 10
• Do not tube two or more pumps in series. It may
prevent the motor from starting and lead to a burn
out.
• Injection point must be below the pump position.
Or siphon action or back flow may result.
• Use care handling the pump. Do not drop. An
impact may affect pump performance. Do not use
a pump that has been damaged to avoid the risk of
electrical damage or shock.
• Do not apply power other than that specified on
the nameplate. Otherwise, failure or fire may
result.
• The pump can not start with full discharge/suc-
tion pressure. Remove pressure before operation.
After a long period of stoppage, pump performance at the beginning of operation becomes occa-
sionally unstable. In this case, warm the pump up
for 10 minutes with no discharge line pressure.

Precautions for use
Caution
Page 11
• Risk of burning. A pump and a pipe surface tem-
perature rises high along with liquid temperature.
Do not touch the pump or pipe surface directly
during operation or right after operation.
Safety instructions
• Always use a suction valve to adjust an air flow.
• The APN-S110 is designed for vacuum application
only. Do not pressurize the discharge line of the
pump.
• Do not clean the pump or nameplate with a solvent
such as benzine, thinner or kerosene. This may
discolour the pump or erase printing. Use a dry or
damp cloth or a neutral detergent.

• When an earth leakage breaker is used and it has

tion.

Overview
Pump characteristics, features and part names are described
in this section.
Introduction
Pump structure & Operating principle
The APN-110 is a diaphragm type air pump with a AC motor.
The rotary motion of the motor is converted through a connecting rod to the
reciprocation of the diaphragm in the pump chamber, where gas is transferred
from the inlet to outlet.

Installation
This section describes the installation of the pump, tubing and
wiring. Read through this section before work.
Observe the following points
• Risk of electrical shock. Be sure to turn off power to stop the pump and
related devices before service is performed.
• If you notice any abnormal or dangerous conditions, suspend operation
immediately and inspect/solve problems.
• Do not operate the pump in a ammable atmosphere.
Pump mounting
Select a suitable place.

See the Precautions for use section before installation.
Anchor the pump.
2
Use suitable bolts or screws.

NOTE
Do not install the pump on an unstable place.

Pipework
Connect tubes to the pump.
Before operation
• Cut the tube ends at.
Tube end (Side view)
Tube connection
a. The short tubing with the minimum bends is optimal to reduce resist-
ance.
b. Use vinyl tubes resistant to the pumping pressure.
Tube I.D. should be equal to the O.D. of the pump
inlet/outlet for the prevention of gas ingress/leak or
other failure.
* Do not have tubing bent or pressed. Otherwise, the tube
end may break.
Connect tubes into the inlet and outlet.
1
Push the tubes into the inlet and outlet as far
as they will go.
* If suction line connection is imperfect, the pump
entrains air and it prevents the pump from bringing
out full performance.

Wiring
Wiring for power source and earthing.
Observe the following points
• Electrical work should be performed by a qualied electrician. Conform
to local electric codes.
• Do not apply power other than that specified on the nameplate. Other-
wise, failure or fire may result.
• Do not perform wiring work while power is on. Otherwise, an electrical
shock or short circuit may result, and consequently the pump may fail. Be
sure to turn off power before service is performed.
• Be careful for electric power not to be turned on during work.

Operation
The pump becomes ready after pipework and wiring is completed.
Pump operation
Before operation
a. Check that the pump is firmly fixed on a mounting position.
b. Check that a suction tube is connected to the inlet and a discharge tube
is connected to the outlet.
* If a suction line and a discharge line are connected the other way around,
pumping process is inverted.
c. Check that every tube connection is secured.
d. Check that electrical wiring is properly done without the possibility of
short-circuit and protected by an fuse.
e. Check that power voltage that is specified on the nameplate is applied
to the pump.
Operation
Open the suction and discharge lines.
1
Turn on power.
2
Operation may occasionally be upset when starting temperature is low.
Warm up the pump under no load operation (a few minutes).
18
Pump operation

After the pump has reached a specied stroke rate, initiate full
scale operation.
• Always adjust an air ow by a suction valve.
• In case electric power has failed while the pump is running, switch
off main power. Otherwise, the motor may not restart or may burn out
depending on a line pressure at the time of power recovery.
After starting, check a pressure gauge to see if suction and dis-
4
charge line pressure are correct and an air ow meter to see if the
specied air ow is obtained.
Before a long period of stoppage (1 week or more)
Release pressure from the pump/tubing and turn off the main power. Keep the
inside of the pump head free from residual gas.
Do not store the pump:
• In a flammable/corrosive atmosphere.
• In a dusty/humid environment.
• In direct sunlight or wind & rain.
• Under vibration.
• Where ambient temperature can exceed 0-40°C.
