2. Operating principle
The APN-085-W is a gas-liquid transfer pump with a small
size diaphragm and special valves, and is designed for
built-in application.
The rotary motion of the motor is converted via a con-
necting rod to the reciprocation of the diaphragm in the
pump chamber, where the mixture of gas and liquid is
transferred from the inlet to outlet.

Installation

- 9 -
Installation
● Observe the rated voltage
specified on the name plate.
Applying any voltage than
the rated one may result in
failure.
● Surface temperature may
rise high in operation but it
dose not mean failure.
Do not touch the pump body
directly or place the objects
which may be deformed by
heat close to the pump.
● Do not use the pump in
a dusty place. Be sure to
provide the inlet with a filter
to prevent foreign mat-
ters from getting into the
pump. Otherwise, the pump
performance may reduce
or the lives of valves and
diaphragm may remarkably
shorten.
● Do not tube two or more
pumps in series. It may pre-
vent the motor from starting
and lead to a burn out.
● The APN-P085-W is
designed to be tubed in par-
allel only. Do not tube it in
series.

2. Installation/ Tubing/ Electrical wiring
2.1 Installation
1. Do not expose the pump to
direct sunlight, vibration and
wind & rain.
2. Keep good ventilation. The
pump should always be free
from the possibility of getting
wet.
3. Ambient temperature should
not fall below 0°C or exceed
40°C. Observe the allowable
maximum ambient humidity
of 90%RH.
4. Install the pump in a clear
and level place.
Select a convenient place
for maintenance and inspec-
tion.
5. Pump fixation
Set the pump baseplate on a con-
crete foundation and fasten cor-
rosion-resistant M5 screws tightly
to prevent the pump from vibrating
during operation.
CAUTION
Do not install the pump on a wobbly pedestal.
2.2 Tubing
1. The short tubing with the minimum bends is optimal to
reduce resistance.
2. Avoid sharp turns or bends.
CAUTION
Do not have tubing bent or pressed. Otherwise, the tube
end may break.
3. Tubes and fittings
Provide tube fittings to the threaded
inlet and outlet (Rc1/8) of the pump. Use
chemically-resistant tubes or tempera-
ture-/pressure-resistant braided tubes as
necessary. Cut the tube ends and have
them flat before insertion.
Stop working upon sensing danger or abnormality.
WARNING

- 11 -
Installation
4. Tube size
For liquid transfer, a suction line bore should be ø4mm or
less. Otherwise, the motor is locked by overfeeding.
A discharge line bore should be ø8mm or more.
CAUTION
Use of a large tube bears the risk of coming off, causing
an air and a liquid leak.
5. Valve mounting
Install a ball valve in a suction line for adjusting an air/liquid
flow or the degree of vacuum and in a discharge line for
shutoff or the convenience of maintenance.
6. Tube and fitting connection
Wrap a sealing tape to the thread of tube fittings and screw
them into the inlet and outlet of the pump. And then fit and
slide tubes down onto the fittings as far as they will go.
NOTE: If suction line connection is imperfect, the pump sucks
air and it prevents the pump from bringing out full per-
formance.
2.3 Electrical wiring
Electrical wiring must be done by a qualified person who has
a full knowledge of safety. We are not responsible for personal
injury or property damage due to nonobservance of this warn-
ing. Contact us or your nearest distributor for wiring as neces-
sary.
■Before wiring
1. Confirm that power is disconnected before work.
2. Wiring work should be done in accordance with relevant
electric work requirements. Use the recommended wiring
accessories.
3. Observe the rated voltage specified on the name plate.
4. Earth the pump through the earth terminal.
5. Install the leakage breaker as necessary. When it has func-
tioned, turn off power and check/solve problems to restore a
normal state.

● Dropping or subjecting the
pump to strong impact, fail-
ure may result.
Handle the pump with care.
● The pump can not start with
full discharge/suction pres-
sure or full liquid. Remove
pressure or liquid before
operation.
● After a long period of stop-
page, pump performance at
the beginning of operation
becomes occasionally unsta-
ble. In this case, warm the
pump up for 10 minutes with
no discharge line pressure.
● Always use a suction valve
to adjust an air/liquid flow.
● If the compressed air or
liquid (higher pressure
than atmospheric pres-
sure) is transferred to the
pump, sharp deterioration
to the lives of the valves,
diaphragm and bearing
may result. The suction line
pressure should be equal
to atmospheric pressure or
vacuum pressure.
● Do not use solvents such as
benzine, alcohol, thinner for
maintenance or cleaning,
otherwise a coat discolours
or comes off.
