High humidity can cause electric shock or fire.
Do not install in an area with corrosive gas (ammonia, acid, ozone gas and
sulfur dioxide) toprevent a shorter lifespan.
あ
Do not install
To prevent an explosion or fire, install in an area free of flammable gases
or organic solvents.
Ambient temperature
Use at ambient temperatures of 36°F to 104° F.
Using less than 36°F will cause unit failure or freezing.
Using over 104°F will cause a shorter lifespan or unit damage.
Do not install
Do not install the unit where it will be exposed to sunshine.
Increased inside temperature can cause unit failure.
Install the unit on a level floor
An uneven floor can cause abnormal vibration, noise or failure.
Do not install

When installing the exhaust duct, take precautions to minimize pressure loss of duct, and attach the ventilation fan at the
exhaust section. Keep distance betweenthe duct inlet andexhaust of the compressor to8 - 12 inches for easy
maintenance.

Installation
▪Piping
(1) Take pressure loss into consideration and decide the piping diameter of the exhaust piping.
(2) Connect the outlet of the compressor and piping by using a rubber hose and flexible tube.
Direct connection to a steel pipe can transfer vibration of the compressor to the pipe causing issues for the
print board of the compressor. Only use a rubber hose for the oil-free compressor.
(3) When there is a riser or concave section in the piping, be sure to install a drain valve at the low end.
Install a drain valve at the low end of the main piping as well.
(4) Installing an air receiver is optional.
When purchasing an air receiver, select a receiver larger than the following capacity.
SLE-10, SLE-10H; 80 Gallon
SLE-15, SLE-15H; 80 Gallon
SLE-20, SLE-20H; 120 Gallon

Installation
▪Electrical wiring
❖Precautions about wiring
たTurn off main electric source before inspecting
or wiring. Deviation from this instruction can
cause electric shock or serious bodily injury.
いOnly a qualified electrician should perform
repairs to prevent electric shock or fire.
いUse a proper wire size.
Using a cable of less than designated size can cause a fire.
けBe sure to ground the unit when wiring to avoid
electric shock or fire.
❖How to run the wire
(1) Remove the door panel.
(2) Remove the lid of control box on the right.
(3) Be sure to securely connect the electric source（L1, L2, L3）and ground.

Test operation
▪Operation
❖Preparation
(1) Check to be sure the air receiver piping has been firmly connected.
(2) Openthe ball valve ofthe compressor air outlet.
(3) Turn onthe main electric source and be sure the display section of the operating panel lights up.

15
Test operation
❖Operation
Push the operating switch to start the compressor.
❖Check pressure increase
Be sure the pressure increases whenthe compressor starts.
CAUTI0N
If the pressure does not increase and an abnormal sound is heard duringreverse rotation, stop the
compressor. Turn off the mainelectric source and then change two out of the three phasestoget the
correct rotation.
Be sure to push the stop switch to stop the compressor and cut the leak breaker to avoid electric shock.
❖Check maximum control pressure
Operatethe unit while the ballvalve of the air receiver is closed.
Be sure the compressor stopsat the pressure shown below.
Model
Max. pressure (psi)
SLE-10, SLE-15, SLE-20
116
SLE-10H, SLE-15H, SLE-20
145
❖Check minimum control pressure
When maximum pressure is reached and compressor stops, open outlet valve and gradually reduce pressure.
Check that compressor restarts at below pressures.
Model
Min. pressure (psi)
SLE-10, SLE-15, SLE-20
101
SLE-10H, SLE-15H, SLE-20
130
＊In case the minimum pressure is changed to 101/130 psi, the volume of the air receiver must be 1.5 times larger than
the recommendation at 94/123 psi.
❖Stop
Push the stop switch and stop the compressor.
After the test operation ends, open the stop valve of the air outlet.

16
Test operation
▪Check control
This compressor uses plural air ends and employs multi-stage control. It can start and stop each air end according to pressure
and air consumption. It automatically selectsthe number of air ends, in accordance withair consumption, and achieves
optimum and uniform operation at all times, as well as energy-saving and labor-saving operations.
(1) Multi-stage control
Among air ends, which are operating under group control, it stopsthe air end which has been operating for a longer time
andrestarts the air end whose operating time has been shorter. This results in equalization of operating time of each
air end and operation with a minimum quantity of air ends,in accordance with air consumption and energy-saving
operation, by eliminating waste of electricity.
❖This figure is an example of the operation of SLE-20 and SLE-20H.
SLE-10 and SLE-10H operate 2 air ends.
SLE-15 and SLE-15H operate 3 air ends.
(2) Prevention of long-term operation
When the operating time of the an air end exceeds the set time, it changes operation from that air end to the one
which has stopped, preventing long-term operation of oneair end. Thislengthens the lifetime of air endsand equalizes
the operating time.
Multi-stage control

▪Changing the HMI Internal Clock
The HMI system clock is set to default by the manufacturer. During an alarm event the alarm log screen displays
occurrence time and date as well as alarm message. The occurrence time and date correspond to the HMI system time
and date, therefore it is recommended to change the HMI system clock to correspond to the local time zone. Follow the
steps below to set the HMI system clock:
1. With HMI ON press and hold the left top corner of the operational screen
2. Maintenance popup screen will appear
Select System mode
3. Go to Main Menu
