Chapter 4 Cautions before Installation
Preparation for safety:
1. Read and fully understand the description and the cautions for safety in the installation and operation manual prior to
installing and operating the HPC system.
2. Always wear the protective goggles when operating the system at high pressure.
3. Install every protective device on the system prior to operating the system at high pressure.
4. Do not expose the body to the discharge outlet of the high-pressure coolant system.
5. Do not operate the pressure control valve to increase the pressure when the orifice for proper adjustment of pressure
(Refer to Table 1) is not installed.
6. Adjust the nozzle only when the high-pressure coolant system is standstill.
7. Never allow spraying the high-pressure coolant to the operator (fatal injury may take place).
8. Pay special attention when moving the system with a forklift truck or a crane not to damage the system. Prevent any
person from walking under the system during movement. Fatal injury or death accident may take place when the system
drops.

--------------------------------------------------------------------------------------------------------------------------------
REV.20161107 V5.0E PFMF Series Installation & Operation Manual 11
Inspection in advance
Safety valve: The HPC system is a strong pressurizing system.
The bypass pressure control valve is mounted on the system to play the role of a safety valve, adjust the maximum
pressure of the system, and prevent discharge with pressure exceeding the defined setting. Improper operation may make
the quality warranty void, and cause injury to the body. Improper operation may also cause damage to the pump or the
system.
Do not remove the pressure control valve from the system. (Fatal injury may take place.)
The manufacturer shall not be responsible for failure due to erroneous or improper operation of the user.
Flow rate at the inlet: The coolant shall be supplied with proper flow rate for operating the HPC system at the optimal
conditions. A coolant pump for supplying the coolant to the inlet of the HPC system is demanded. Make sure that the
flow rate of the coolant supply pump is appropriate before install the pump. The maximum flow rate of the high-
pressure pump installed on the HPC system is (Refer to Table 1). The minimum flow rate of the coolant supply pump
is (Refer to Table 1). Adjust the pressure for the flow rate. When fine particles accumulated on the filter, the flow rate
of the coolant supply pump decreases, and air is introduced into the high-pressure pump installed on the HPC system to
cause problem.
Filtering: You can select the filtration grade from three types; 50-, 25, and 10-micron.
Viscosity of coolant: It is recommended to use coolant or oil with viscosity lower than 125 SUS (cSt 26).
(The higher the viscosity of the coolant grows, the lower the life cycle of the filer gets.)
Considerations before Installation
a. Make sure that the coolant supply systems (the hose, the valve, the tube, and the coolant coupling) are appropriate for
the operation pressure prior to installing the HPC system.
b. Replace contaminated coolant with fresh coolant, and remove chips and iron particles from the coolant tank of the
system to maximize the effects.
c. Tubing materials of PT/NPT and coolant tubing material of 37° JIS are used on the HPC system. The JIS tubing material
is designed to prevent leakage under high pressure and in vacuum without pipe seal. The PT/NPT tubing material shall
be wrapped with the pipe sealant (e.g., Loctite 585), or Teflon tape. The Teflon tape shall carefully handled to prevent the
tape from being introduced inside the tubing.

REV.20161107 V5.0E PFMF Series Installation & Operation Manual 12
Chapter 5 Installation
Fixing the system
1. Operate the HPC system only after fixing the system on a flat floor.
2. There are bolts and devices on the bottom of the HPC system for fixing the system.
3. When the system not fixed moves or falls due to external impact during operation, the system is damaged
and causes fatal injury to the operator.
Tubing
1. It is recommended to keep the tubing on the HPC system and the system body as short as possible.
Consider the distance to the system body from the tubing or wiring supplied together with the HPC system.
2. Consider the situations of the filter replacement, adjusting the discharge pressure, and checking and
replacing the pump oil, and install the HPC system at a place with sufficient and appropriate space for the
situations.
3. It is recommended to install partition on the coolant tank of the system body to separate the pump
supplying coolant to the HPC system, and the area where coolant is recovered from the system body is
introduced. This design reduces air introduced when supplying the coolant to the HPC system.
Tubing at the inlet (coolant supply inlet)
1. Use the tubing at the inlet (e.g., hose and tubing materials) with inner diameter larger than 9.52 mm(3/8").
2. If it is inevitable to use the elbow tubes, it is recommended to use the elbow or 45° rather than 90° angle.
Do not use elbow of 90° angle as possible.
3. Use sealing materials (sealant or Teflon tape) on the PT/NPT tubing at the inlet of the HPC system. If there
is slight leakage on the tubing, air is introduced into the system to generate vacuum.
Please note that the JIS 37° tubing materials does not demand sealing materials.
4. When using a shutoff valve, use a valve with inner diameter of 9.52 mm(3/8") of full-open mode.
5. Do not directly connect solid tubing such as steel pipes to the HPC system. Use tubing materials such as
flexible hose to absorb effects from vibration.
6. Install the tubing in such a way to minimize vibration and load on the tubing.
Caution: Do not installed a shutoff valve on the bypass.
Rapid increase of pressure damages the HPC system, and causes fatal injury to the body.
Overflow tubing
1. It is recommended to use overflow hose with inner diameter of 1-1/2" or larger. If coolant flow is blocked,
the clean coolant tank may be overflowed. Keep sufficient inclination and elevation level from the coolant tank.
2. If the clean coolant tank is overflowed yet, adjust the flow rate of the coolant supply pump. (Adjust the
operation duration with a timer, or install a valve to adjust the supply flow rate.)
3. The overflow hose connected to the coolant tank of the system shall be located at a position farthest from
the inlet of the coolant supply pump. Introduction of air affects capabilities of the coolant supply pump.
4. Task appropriate action to prevent removal of the overflow hose from the coolant tank.

--------------------------------------------------------------------------------------------------------------------------------
REV.20161107 V5.0E PFMF Series Installation & Operation Manual 13
High-pressure tubing (discharge)
1. Use a flexible hose longer than 0.9 meter for connecting the high-pressure discharge outlet of the HPC
system to the connection port (or tubing material such as a pipe) fixed on the machine.
2. The flexible hose is demanded to reducing vibration of the tubing for coolant. Pulsation dampening assembly
is more effective for dampening pulsation generated from high pressure.
3. Make sure that the coolant tubing on the machine is appropriate for the minimum operation pressed of 150
bar (2100 psi) prior to installing the HPC model. If not, replace with the appropriate tubing.
4. It is recommended to use a hose with inner diameter of 9.52 mm (3/8"). Do not use a hose with inner
diameter smaller than 3.17 mm (1/8"). If it is inevitable to use the hose smaller than the size, please contact
KEMTECH for advise.
5. The tubing at the high-pressure outlet of the HPC system is 3/8" (-12) 37° JIS male hydraulic tubing.
Label indication cautions for operator
1. Affix the caution label as illustrated on the figure
on the door of the system body at height of the
eyes of operator.
2. Operate the HPC system only after fully
understanding the installation procedures.
Then, check the cautions prior to installation again.
Chapter 6 Electric Wiring
Caution: Electric wiring and circuit configuration shall be performed by qualified electric engineer.
Never fail in making sure that the power is turned off prior to operation.
Caution: Pay special attention to how to operate and shut down the high-pressure pump motor before
operating the HPC system. Frequent turning-on and turning-off generates overheating, and may cause
damage to the motor, the magnetic connector and the shaft of the high-pressure pump, and malfunction of the
motor.
If it is required of operation at high pressure for a short period (i.e., several turning-on and-off operations are
required in a few minutes), install the 3-way solenoid valve for high pressure. It is desirable to operate the

--------------------------------------------------------------------------------------------------------------------------------
REV.20161107 V5.0E PFMF Series Installation & Operation Manual 14
motor with a single control signal. Use a separate signal on the solenoid valve for high pressure to selectively
operate discharge and drain of the valve.
Power connection
The factory default of the HPC model is low voltage wiring (220V, 50/60 Hz, 3-phases). The rotation direction
may be switched dependent upon the wiring of the main power. In such a case, the motor or the pump may
seriously be damaged. Immediately shut off operation, and correct the wiring for right rotation direction.
When changing the wiring to 380V, correct the wirings of the high-pressure pump, the control box, and
the coolant supply pump also. Supplying power of 380V without correcting the wiring may cause
significant failure to the system.
The system connector cable of five meters is provided to the power supply and the controller respectively in default.
(The cable length may vary, or no cable is demanded upon request of the customer.)
Make sure of grounding.
Alarm control circuit (Refer to the electric diagram)
The following level switches are installed on the HPC system for monitoring flow rate of coolant supplied to the inlet of
the high-pressure pump:
FS1- CLEAN TANK LOW S/W(Standard) : Used for the signal of turning on/off signal of the coolant supply pump,
or control of the level alarm. (Location at height of approx. 50 liter of
flow rate)
FS2- DIRTY TANK HIGH S/W(Standard) : Used for the signal of the bag filter (Location at height of approx. 2.5
liter of flow rate)
FS3- CLEAN TANK MID S/W(Option) : Used for the turning-on signal of the coolant supply pump (Location at
height of approx. 60 liter of flow rate)
FS4- CLEAN TANK HIGH S/W(Option) : Used for the turning-off signal of the coolant supply pump (Location at
height of approx. 80 liter of flow rate)

--------------------------------------------------------------------------------------------------------------------------------
REV.20161107 V5.0E PFMF Series Installation & Operation Manual 15
Controlling the coolant supply pump
6-1. When the standard level switches (FS1 and FS2) are only mounted
1-1 Upon continuous supply coolant by the coolant supply pump
a. The flow rate of the coolant supply pump shall be greater than the discharge flow rate (max. 20
liters/minute), and smaller than the overflow rate. The overflow rate significantly varies dependent upon
the tubing conditions including the elevation difference between the tank of the HPC system and the
coolant tank of the machine, tubing inclination, and the tubing diameter. The flow rate shall be
determined upon initial operation not to overflow the tank of the HPC system. The most common
method of adjusting the flow rate is installing a valve on the inlet port of the HPC system. (Set the inlet
flow rate based on the discharge volume of the HPC system at zero.)
b. When the FS1 signal is open (normal open), operation of the high-pressure pump of the HPC system shall
be shut off. (Coolant alarm) Operating the high-press pump without coolant significantly reduces the
life cycle of the pump. The interlock circuit shall be configured on the HPC system.
1-2. When controlling the coolant supply pump with a timer
a. Adjust the operation duration of the coolant supply pump between 30 and 80 seconds when the FS1
signal is open (normal open).
Frequently turning on and off the supply pump within a short period may affect the life cycle of the supply
pump. Check the supply flow rate, and adjust the operation duration not to overflow the clean tank of the
HPC system.
If the flow rate of the supply pump is greater than 60 liters/minute, install a valve on the inlet port to
adjust the flow rate.
b. Operation of the high-pressure pump of the HPC system shall be shut off when the FS1 signal is
open (normal open), and the coolant supply pump operates, but the FS1 signal is not closed (normal
close) after 10 to 15 seconds. (Coolant alarm)
Operating the high-press pump without coolant significantly reduces the life cycle of the pump. The
interlock circuit shall be configured on the HPC system.
6-2. When all of the standard and the optional level switches (FS1, FS2, FS3 and FS4) are mounted
a. When the FS3 signal is open (normal open), use this signal as the on-signal of the supply pump.
b. When the FS4 signal is closed (normal close), use this signal as the off-signal of the supply pump.
c. When the FS1 signal is open (normal open), operation of the high-pressure pump of the HPC
system shall be shut off. (Coolant alarm)
Operating the high-press pump without coolant significantly reduces the life cycle of the pump. The
interlock circuit shall be configured on the HPC system.
Controlling the filter replacement alarm (FS2)
1. When the FS2 signal is switched from being closed (normal close) to being open (normal open), use this
signal as the filter replacement alarm signal.

default is 16 hours.)
13) Filter AL: Signals replacement of contaminated filter.
- Standard: After replacing the filter, open the drain valve of the dirty tank to remove the coolant,
and then close the vale again. Otherwise, the system does not operate, or no alarm does
not place even if the filter is contaminated again. (Stress is caused to the machine.)
- Full Option: Replace the filter, and the rotate switch 20. (in either direction; A-> B, or B-> A)
Reset Play 5 lights, the coolant in the dirty tank is automatically removed, and the
tank closes after certain period. The mode is switched to the automatic filter
switching preparation mode. Refer to description in 12) above.

Chapter 7 Trial Run
Cautions for first trial run:
1. The level of the coolant in the coolant tank of the system body shall sufficiently high for operation of
the HPC system.
2. All the shutoff valves installed on the coolant supply line shall be kept open.
The high-pressure discharge tubing shall not be blocked.
3. All the connections on the tubing shall securely be tightened.
4. Fully turn the adjusting bold of the pressure control valve in the vicinity of the high-pressure discharge
outlet in counterclockwise direction to reduce the spring pressure inside the valve to minimize the
pressure discharged from the pump during the trial run.
(Refer to Chapter 7.)
5. The filter shall be installed inside the HPC system. At least one of the valves on the inlet line (filter 1
and filter 2) shall be kept open. The valve on the high-pressure shall be kept open.
6. The level of the coolant inside the clean tank shall be kept at sufficient height. (1/3 to 2/3 of the tank)
7. Temporarily run the high-pressure pump (two to three seconds) to check the rotation direction.If the pump
rotates in wrong direction, switch two phases from U, V and W.
8. Make sure the high-pressure pump normally operates, and
high-pressure discharge is made normal.
9. Check the coolant supplied into the clean tank for any
overflow or low level to cause an alarm.
10. Check the system for any abnormal noise.
Check the coolant for unstable flow.
11. If there is air lock on the high-pressure discharge tubing,
the pump may not operate normally.
Caution: The needle of the discharge pressure gauge shall steadily move. If the needle jerks or trembles,
there is a large volume of air in the coolant. (Check the coolant supply system for normal operation.)
Chapter 8 Pressure Setting and Operation of Pressure Control Valve
The pressure control valve is a safety valve to prevent pressure exceeding the standard value on the HPC
system. The pressure setting of PFMF 000-00 shall not exceed (Refer to Table 1) in any case.
How to adjust the pressure setting on the pressure control valve:
1. Make sure that the power to the HPC system and "M" code on the machine are kept OFF.
2. Remove the hose tubing from the high-pressure discharge
tubing, and insert the orifice for measuring pressure
supplied together with the HPC system in the discharge
tubing. (Refer to the figure on the right.)
3. Loosen the locking nut.
