5 INSTALLATION

5.1 Installation Site Guidelines/Considerations

Before attempting to install the HLP6 Oil Purifier consider the following:

Allow for 36 inches of clearance on all four sides of the HLP6 skid

Choose a location with cool ambient temperature (100 o

F [38 o

C] or less is ideal)

Position the HLP6 on equal height with reservoir

The HLP6 skid should be positioned on the same level as the oil reservoir (inlet pressure range must be within the specifications of section 4.6 and/or the inlet pressure gauge placard located on the gauge cluster). Avoid installing the HLP6 skid below the reservoir, as this may cause flooding.

The inlet hose/pipe must be suction-rated with a minimum inside diameter of 1.5 inches

(3.8 cm).

The inlet hose/pipe length should not exceed 20 feet (6 m) in length. Avoid 90 degree bends/fittings. Long inlet hose/pipe runs along with 90 degree bends will cause a low pressure in the inlet plumbing and potential difficulty starting the HLP6 Oil Purifier.

5.2 Installation Tips

!

Installation Tips!

SEAL MATERIAL: Ensure the HLP6 seal material is compatible with the process fluid.

ELECTRICAL SUPPLY: Must match the HLP6 electrical requirement.

AVOID HIGH HEAD PRESSURE: Limit Head pressure to 10 psi (0.68 bar) or less

ACCESSIBILITY: Allow 36 inches of clearance on all four sides of the HLP6

CODES & REGULATIONS: Always observe Federal, State, Local and plant regulations

MAN-HLP6-R0-USA August 15, 2009 Page 15

5.3 Connecting the HLP6 to a Fluid Supply

!

!

Caution – Suction Hose Required!

When connecting the reservoir to the inlet port of the HLP6 Oil Purifier it is absolutely critical that hard piping or a hose rated for suction be used. Non-suction-rated hoses can collapse internally and restrict the flow of oil to the skid. These internal collapses are often not visible from the outside of the hose.

Use hard piping or suction-rated hose on

the inlet!

HLP6 Inlet Plumbing Tips!

PIPING: Use hard piping wherever possible. Limit the use of 90° bends.

HOSE: Inlet hose must be rated for suction.

PIPE/HOSE DIAMETER: Inlet plumbing to HLP6 must be 1-1/2” (3.8 cm) ID minimum

PIPE/HOSE LENGTH: Inlet plumbing length should not exceed 20 feet (6 m) unless instructed otherwise by Pall Corporation

ADDITONAL FITTINGS: Remove unneeded fittings minimize leaks & pressure drop

Inlet Plumbing Line Leaks

Leaks in the inlet plumbing may be difficult to detect due to the low pressure condition inside the inlet line. Drips or fluid loss may not be apparent. Ensure that a minimum number of connections are used and properly tighten all connections. Avoid NPT-type fittings if possible.

MAN-HLP6-R0-USA August 15, 2009 Page 16

Inlet Line Connection to the Reservoir

!

Caution – Avoid connecting the HLP6 to the very bottom of the reservoir!

Pall Corporation advises not to draw fluid into the HLP6 from the very bottom of the reservoir. Although every oil reservoir is different a layer of sludge and or free water may reside at the bottom of the oil reservoir. Ingesting sludge into the HLP6 may prematurely plug the inlet strainer and other filters on board the purifier. Free water will not harm the

HLP6, but operators are advised to manually drain collected free water and take advantage of the mechanical separation.

The diagram below is an example of best practice water prevention and monitoring techniques. Pall Corporation recommends plumbing the HLP6 as shown. Alternative configurations may be acceptable; check with Pall prior beginning the plumbing project.

Recommended hookup of HLP6 to reservoir

5.4 Returning Fluid Back to the Reservoir

!

HLP6 Return Line Plumbing Tips!

DIAGRAM: Refer to plumbing diagram (above) for general layout plumbing

PIPING/HOSE: MUST be rated for 150 PSI (10.3 Bar) operation.

PIPE/HOSE DIAMETER: Return plumbing must be 1” (2.54cm) ID minimum

RETURN LOCATION: Avoid oil splash: return oil below fluid level line.

RETURN LOCATION: Return fluid to opposite side or end.

RETURN LINE PRESSURE: The pressure in the line returning fluid from the

HLP6 back to the reservoir should not exceed 60 PSI (4.1 Bar) on HLP6 outlet gauge.

ADDITONAL FITTINGS: Remove unneeded fittings to minimize backpressure.

8 BASIC HLP6 OPERATING PROCEDURES

WARNING – Complete sections 5 & 7 First!

Before proceeding review these sections:

# 5 INSTALLATION

# 7 ELECTRICAL CONNECTION

8.1 Oil Flow Path through HLP6

During normal operation oil will pass through the HLP6 Oil Purifier as indicated by the gold arrows. Key system components are identified with numbers which correspond directly to the number found on the hydraulic schematic drawing.

Oil is drawn into the HLP6 via the pump/motor group (# 4 - 6). The fluid passes the inlet gate valve (#31) and inlet strainer (#1), then through the pump/motor group. Fluid travels through the check valve (#7), heater (#9), sight glass (#10), and delivered to the vacuum tower (#15). Sight glass (#16) shows the tower fluid level. Oil is removed from the vacuum tower via a second pump/motor group (#4/18). The oil is passed through a polishing filter (#20) and check valve

(#22) then returned to the oil reservoir.

MAN-HLP6-R0-USA August 15, 2009 Page 25

8.2 Air Flow Path through HLP6

When running, the HLP6 Oil Purifier will maintain a steady flow of air through the vacuum tower.

The air flow path is indicated by the green arrows. Key system components are identified with numbers corresponding directly to the number found on the hydraulic schematic drawing.

Shortly after starting the HLP6 oil purifier the vacuum pump & motor (#25 & #26) will start and air within the vacuum tower will be exhausted. Ambient air will be drawn into the vacuum tower through the inlet breather filter (#10) and vacuum adjustment valve (#12). Filtered air will travel upwards through the vacuum tower, through the demisting pad (# 15A) and into the vacuum pump

(# 26). Air leaves the vacuum pump, travels through a final coalescer (#29), and exhausts to atmosphere.

MAN-HLP6-R0-USA August 15, 2009 Page 26

8.3 Pre-startup Checks

Check vacuum pump gear oil level (photo below, see maintenance section for oil type and fill procedure)

Close all drains and vents (locations indicated below).

Completely open the inlet gate valve (#31).

Open all valves in the oil supply line to the purifier.

Open all valves in the oil return line from the purifier to the reservoir.

Verify condition of inlet air breather (see maintenance section for change-out procedure).

MAN-HLP6-R0-USA August 15, 2009 Page 27

8.4 HLP6 Energizing and Boot-up

Turning the main disconnect to the “ON” position will “boot up” the HLP6 Oil Purifier. During the boot-up process the HMI will display screens as shown below. When the boot-up process is completed the HMI will display the HOME page with the words “PURIFIER READY”.

Purifier Booting Up Purifier Booted Up Ready to Start

MAN-HLP6-R0-USA August 15, 2009 Page 28

8.5 Starting the HLP6 Purifier

Complete sections 7.1, 8.3, & 8.4 first! Ensure all valves connecting the HLP6 to the reservoir are

100% open. Only after the HLP6 has booted up and the HMI displays “PURIFER READY” can the HLP6 be started. To start the purifier press the red “START” button on the front panel. The start button will illuminate immediately after the start button is pressed.

Purifier is ready to start

Purifier Running

Special Note about lamp colors: The HLP6 uses the Power Generation standard lamp coloring scheme. Green light for safe / purifier off / purifier not running.

Red light for energized / purifier running / purifier live.

MAN-HLP6-R0-USA August 15, 2009 Page 29

8.6 Running and Adjusting the Purifier

A few seconds after pressing the start button the inlet and outlet pumps will start (which one starts first depends on the oil level within the tower). Several seconds later the vacuum pump will start and tower vacuum will begin to build. Oil will be seen flowing in the upper sight glass. The oil level within the tower will become stable in the lower sight glass. Shortly thereafter, if the heater is enabled, it may come on depending on the heaters set point in relation to the current temperature.

With the purifier running make the following adjustments and observations:

Adjust the tower vacuum to approximately 18” Hg using the needle valve (#13). Clockwise rotation of the needle valve will increase tower vacuum. Counter-clockwise rotation will decrease tower vacuum.

Caution: When adjusting the needle valve, use only ½-turn (180 degree) or ¼-turn (90 degree) increments. It may take up to 60 seconds for the tower vacuum to stabilize. Do not over adjust.

Vent air trapped within the polishing filter housing using the needle valve (32).

MAN-HLP6-R0-USA August 15, 2009 Page 30

8.7 Gauge Observations

The HLP6 gauge cluster is shown below. After approximately 60 seconds all gauges should be within the range stated on the placard located below the gauge. If the operator observes a reading outside the stated ranges the HLP6 may issue an alarm condition. The operator should turn to the troubleshooting section of this manual for further instructions.

MAN-HLP6-R0-USA August 15, 2009 Page 31

8.8 Enabling the Heater & Changing Heater Set Point

The HLP6 heater is enabled/disabled using the ON/OFF switch located on the front panel. When the heater is enabled the heater logic determines when to energize the heater.

When the heater is

energized the switch will illuminate.

Heater Enabled, not energized Enabled & energized Heater disabled

The heater set point is factory set at 120 o

F (49 o

C). The set point is adjustable using the purifier’s

HMI (human machine interface). The set point can be changed if the purifier is running or not.

When the desired set point is reached, press F1 to return to the home page.

8.9 Cold Startup Condition - Oil Viscosity Above 1000 cSt (4650 SUS)

The HLP6 Oil Purifier will not run properly with fluids having a viscosity above 1000 cSt. The user should be aware of cold fluid conditions resulting from hoses laying on cold floors. During colder months of the year, users are advised to drain fluid from purifier supply line hoses when the oil purifier is not being used. It is especially important to keep fluid supply lines to the oil purifier as short as possible to minimize the effects of cold fluid introduction to the HLP6.

8.10 Stopping the Purifier

To stop the HLP6 press the “stop” button. All pumps and motors will stop and the stop button will illuminate as shown below.

MAN-HLP6-R0-USA August 15, 2009 Page 33

8.11 Draining the Purifier

Considerations Prior to Draining: The HLP6 Oil Purifier is equipped with an automatic draining feature. To maximize the effectiveness of the drain mode, the user should disconnect the fluid supply line from the inlet of the purifier. This will prevent additional fluid from being drawn into the purifier and allow for better drainage overall. If the above-mentioned procedure is followed the purifier will have approximately 1 gallon of fluid still left on board.

If more draining is desired, the user should manually drain the heater, vacuum tower and polishing filter using the manual ball valves located at the bottom of each of these components.

Enabling Drain Mode: The operator should read and understand the section above: titled

“Considerations Prior to Draining”.

• To activate the drain mode the purifier must be stopped and the power energized.

• Press and hold the stop button for 5 seconds. After 5 seconds the HMI screen will display the screen below and the user can release the stop button.

• The user can now start the automatic drain mode by pressing the start button. At that time the inlet pump will run for 45 seconds, and the outlet pump for 90 seconds.

• The user may also start and stop either the inlet or outlet pump individually. Pressing the

F2 key will start the inlet pump; pressing the F4 will start the outlet pump

• When draining is complete, exit to the “Home Page” by pressing F3 (HOM)

THEORY OF OPERATION & COMPONENT IDENTIFICATION

9.1 General Claims

The HLP6 Oil Purifier can be used as a portable or stationary vacuum dehydration unit. It has been designed to purify hydraulic, lubricating, insulating and gear oils by removing water, particulate contamination, and gases.

Water – 100% of free water, 75% of dissolved water

Gases – 100% of free & entrained gases, 75% of dissolved gases

Dirt – including silt and other solids or particulate contaminants.

9.2

Theory of Operation

Oil contaminated with water, gas, and particulate is purified on-board the HLP6 purifier.

Dry air in the tower is obtained by expansion: Ambient air is drawn into the tower by the vacuum pump, and expanded to approximately 4 times its former volume (depending on vacuum set point). As the inlet air volume expands 4-fold, the relative humidity of that air decreases 4-fold.

The resulting air inside the tower has effectively been dried.

The contaminated oil is drawn into the purifier via the inlet fluid pump. The oil passes through the heater and enters the top of the tower. The oil cascades from the top of the tower to the bottom via gravity, passing through a column of stainless steel rings in the process.

While the contaminated oil travels down the column, water trapped in the oil converts from a liquid phase to a gaseous phase. The gasses trapped in the oil will expand as per Boyles Law. As the oil travels down the column the vacuum pump maintains airflow through the tower. Water vapor and expanded gases are removed through the top of the tower by the vacuum pump and are discharged to atmosphere downstream of the vacuum pump.

Dry, degassed oil at the bottom of the tower is drawn out via the fluid pump and passed through the absolute rated filter before returning to the reservoir.

11.1 Phase Reversal / Low / High Voltage

The HLP6 Oil Purifier will announce the “PHASE REVERAL/LOW/HIGH VOLTAGE” alarm when the supply voltage is out of the expected range. Listed below are the 4 possible causes for this alarm. The HMI does not identify which of the 4 conditions is causing the alarm, only that an alarm condition exists.

Phase Reversal – supply voltage is out of phase, switch 2 of 3 supply voltage legs.

Phase Loss – one or more of the supply voltage legs is not energized

Low Voltage – the voltage supplied to the purifier is below the lower threshold.

High Voltage – the voltage supplied to the purifier is above the upper threshold.

To determine which of the 4 possibilities is causing the alarm the operator must open the electrical panel and view the lights on the sensor.

Explanation of LED Light Sequences

Normal Operation – Green LED on & Red LED’s off

Phase Reversal – Alternating flashing of Green & Red LED’s

Low Voltage – Green LED flashing & Red Low Voltage LED on

High Voltage – Green LED flashing & Red High Voltage LED on

Phase Loss – Green LED flashing

WARNING – Do Not Adjust Supply Voltage Sensor!

The sensor is designed to protect the HLP6 Oil Purifier from damage caused by fluctuating supply voltage conditions. The sensor is factory set and should not be adjusted unless instructed to do so be Pall

Corporation. Adjusting the sensor outside of the factory set points will void the HLP6 Oil Purifiers warranty.

Re-start the purifier, if the alarm re-occurs, verify that the pressure sensor changes state at approx 10 psi. Replace the sensor if needed.

11.7 High Tower Level Shutdown

The fluid level within the vacuum tower of the HLP6 is monitored by level floats. The fluid level can be viewed in the lower sight glass (shown below). Under normal conditions the fluid level will stay virtually unchanged about half-way up in the sight glass. Conditions may arise when the fluid level is above the expected range, under those conditions the HLP6 Oil Purifier will issue a

“HIGH TOWER LEVEL SHUTDOWN” alarm.

Possible causes of this alarm are:

Closed valve in fluid discharge line (between purifier and reservoir)

High backpressure in fluid discharge line resulting from head pressure or other obstruction

Tower vacuum level too high (fluid pump can not pull fluid out of the tower)

Fluid viscosity increase resulting from temperature decrease

Broken or obscured outlet check valve (not opening fully)

Suction leak or obstruction at the inlet to the purifiers discharge pump

Coupling failure or broken pump shaft between discharge pump and motor

Damaged or failed outlet pump relief valve

Large amount of “foam” in the fluid entering the discharge pump

Conditions may arise when the fluid level is below the expected range; under those conditions the HLP6 Oil Purifier will issue a “LOW

TOWER LEVEL SHUTDOWN” alarm.

Possible causes of this alarm are:

• Fluid is too viscous 1000 cSt (warm the fluid in the supply line and tank)

• Air leak on inlet line (loose fittings, inlet line not submerged in tank)

• Large amount of “foam” in the fluid entering the purifier inlet pump

• Coupling failure or broken shaft between inlet pump and motor

• Broken or obscured inlet check valve (not opening fully)

• Failed pressure relief valve on inlet fluid pump

11.19 High Water Saturation Alarm

Conditions may develop in which the water content in the reservoir or tank will spike high. The cause of the water spike can be attributed to many factors which will not be discussed within this IOM. HLP6 Oil Purifier models equipped with a water sensor will measure the dissolved water content of the fluid entering the purifier, upstream of the heater. The HLP6 is factory programmed to issue to issue the “HIGH WATER SATURATION ALARM” if the dissolved water content at the inlet of the HLP6 exceeds 90% saturation. The alarm trigger point can be adjusted, see section 12 of this manual for details.

Anytime the dissolved water content approaches or exceeds 90% saturation the user should take immediate action to pinpoint and arrest the source of the water ingression. If the water ingression rate exceeds the water removal rate the oil reservoir or tank may overfill. The High Water Saturation Alarm should be taken seriously and immediate action must be taken to reduce the source of water ingression.

11.20 Heater Contactor Failure

MAN-HLP6-R0-USA August 15, 2009 Page 76

The heater contactor for the HLP6 Oil Purifier is monitored for proper operation at all times. This alarm is monitored by auxiliary contacts on the heater contactor.

The auxiliary contacts are wired normally open with wire #3 for 24 VDC and wire

#45 for the signal is wired to input X21 on the PLC. When the PLC engages the heater it looks for a 24 VDC acknowledgment signal on wire #45. If the signal is not detected within 1 second the “HEATER CONTACTOR FAILURE” alarm will be announced on the HMI screen. The purifier will continue to run under this alarm condition.
