Preface
With the purchase of the E&P Hydraulics levelsystem your caravan will be automatically levelled and/or
put stable placed with one push of a button.
Never a caravan:
• that moves when you walk through it, or if it is windy.
• which you suffer from unwanted opening or closing doors.
• where the shower water runs through to the wrong side caused by height differences.
• wherein you have the problem of sleeping in a lean angle.
All issues that are fixed with the E&P Hydraulics levelsystem.
The ergonomic design ensures effortless handling and the sympathetic good looks will automatically
enhance your working environment. It is based on proven E&P Hydraulics technology which forms the
basis of all our E&P Hydraulics products. After installation one button operates the entire system.

1. The E&P Hydraulics levelsystem
1.1 Operating of the levelsystem
The E&P Hydraulics levelling system is an electrically/hydraulically driven system.
A hydraulic pump is powered by a 12V direct current motor, which will pump hydraulic oil through a
system of hydraulic hoses two hydraulic axle-supports and four hydraulic corner-supports, with the aim
of stabilizing and levelling the caravan. Mounted to this pump are the oil reservoir, the valve block and
solenoid (magnetic) valves.
The E&P Hydraulics levelsystem is electronically controlled by an operating system or so called mainunit, which is mounted at a central location in the caravan.
The levelsystem can be operated either fully automatically or manually by means of a built-in control
panel and/or (optional) remote control. Most frequently the control panel is mounted in the sidewall at
the entrance of the caravan.
The jacks have the weight bearing and levelling capacity your caravan requires. Each axle-support has
a 180 mm. foot plate on a flexible pivot, guaranteeing the greatest firmness possible on any surface.

1.2 Using the hydraulic levelsystem
The levelling system is designed to be used for creating a stable and horizontal position for the
caravan. (the maximum slope on which it is possible to level the caravan is 8%).
With the electronic spirit-level, the caravan is adjusted horizontally over its complete width with the aid
of the two axle supports.
Then the caravan is adjusted horizontally in the longitudinal direction with the aid of the four corner
supports. The whole caravan will be stabilized via the control panel or the (optional) remote control.
1.3 Specific characteristics of the hydraulic levelsystem
• Automatically extending the jacks from a retracted position.
• Automatically retracting the jacks from a extended position.
• Automatically or manually levelling the jacks.

2. Safety warnings
Fail we to observe the following warnings may lead to damage to the caravan and/or serious physical
injuries.
• Using the E&P Hydraulics levelling system for other purposes than supporting the caravan is officially
forbidden according to E&P Hydraulics limited warranty.
• This product is exclusively developed as a levelling system and is not designed to be used for other
work underneath the caravan. If the system is utilised to help with changing a wheel, it is the
responsibility of the user to ensure the caravan is secured safely in position. Never lie underneath a
jacked-up vehicle, as this is dangerous and could result in serious injury! Please always refer to your
caravan manufacturer’s recommended jacking procedures.
• When the system is operating, all persons and animals should keep their distance.
• Body parts (e.g. hands and eyes) should never come into contact with released fluids. Oil leaving the
hydraulic levelling system may be under high pressure and could cause serious injuries to the skin.
Consult a doctor immediately in case of accident.
• The caravan should be parked on a solid, non-slippery surface. The parking location must
be free of holes and free of waste and surrounding objects.
• If the caravan is parked on very soft soil, you must place a support plate under each jack in order to
distribute the weight.
• Check that the installation of the hydraulic levelsystem is performed by a skilled mechanic with
sufficient practical experience and technical E&P Hydraulics training.
• In case of repairs/malfunctions to the hydraulic levelsystem: know what you are doing. Never try to
repair it yourself, but consult your installer or dealer.
• Fully read this user manual before using the hydraulic levelsystem.
• After deploying the hydraulic levelsystem ALWAYS make an inspection tour around the caravan, just
to be sure the caravan stands stable (all hydraulic jacks are on the ground).

(no. 7)
Step 1 Press 1x on the button “ON / OFF” (no.5) to switch the levelsystem ON.
The “E&P-logo” LED lights up, indicating that the levelsystem is switched on.
When there is insufficient or no battery voltage, the indicator LED
‘’LOW VOLTAGE’’ (no.2) lights up.
In automatic levelling, the caravan must be tilted a few degrees forwards. The
system will indicate whether you have positioned the caravan level enough. If you
have not, the indicator LED “FRONT WHEEL” (no.3) lights up, and the system
cannot be started automatically. The front wheel must be wound down.
When the caravan leans too steeply, the indicator LED ‘’SLOPE TOO STEEP’’
(no.1) lights up.
REMARK: When the caravan leans too steeply, the caravan cannot be auto matically levelled. You now have two options: Stop the levelling procedure and
place the caravan on a flatter surface and start again with automatic levelling
procedure. Or go further with manual levelling procedure.
Step 2 Press 1x on the button “AUTOMATIC MODE” (no.7) to start the automatic
levelling procedure.
When the levelling procedure is complete, the indicator LED “LEVEL” (no.14)
lights up GREEN.

User manual
E&P HYDRAULICS
4.2 Manual levelling
The procedure for manual deployment/extension of the axle and corner supports is as follows:
The manual levelling function is mainly used when automatic levelling is not possible due to a large tilt
of the caravan. With the help of this feature it is also possible to change the position of the caravan;
think of your sleeping comfort. Most people prefer to sleep with their head up slightly. Depending on
the orientation of the caravan with this feature you can manually adjust the angle where necessary.
REMARK: On the side where the caravan is low, fill the space under the axle support (footplate) with
some boards to compensate the difference in height. This will avoid the risk it is not possible to level
the caravan due to a too large difference in height. In case of too large height difference the hydraulic
jacks may come to the end of their stroke.

5. Extra functions
5.1 Calibration (setting the zero point)
The calibration procedure described below has already been carried out at your dealer/installer.
You don’t have to perform this procedure by yourself. E&P Hydraulics has decided to include this
chapter as an extra in this manual in case of failure and/or service & repair matters.
Consider setting the zero point** as a condition to make it possible to level the caravan automaticallyand/or manually. When this operation, for some reason, has not been done or has been carried out
incorrectly, it is not possible to level the caravan.
** The zero point is the point (level) to which the hydraulic leveling system (in an automatic cycle)
returns.
Start: Manual levelling
Before automatic levelling can be activated, you must set the zero point. For setting the zero point, you
must first perform the manual levelling procedure.
REMARK:
Do this by placing a spirit level in the center of the caravan.
ATTENTION !
Never put the rear brackets first to the ground. This in case creating too much
load on the caravan.

5.2 Remote control programming
5.2.1 Introduction
The procedure described below has already been carried out at your dealer/installer. You don’t have to
perform this procedure by yourself. E&P Hydraulics has decided to include this chapter as an extra in
this manual, in case of failure and/or service & repair matters.
When this operation, for some reason, has not been done or has been carried out incorrectly, it is not
possible to level the caravan with the remote control.
5.2.2. Antenna
Check if there is an antenna connection on the operating system (see picture below). If this is not the
case, the remote control CANNOT communicate with the hydraulic levelling system. In principle, the
antenna connector and the antenna are always present when you purchase the levelsystem including
a remote control unit.
If you purchased the remote control at a later stage (i.e. not with the levelsystem), then you should
remember that this antenna connection on the operating system (main-unit) could be missing.
The presence of the antenna is dependent on the age of the levelsystem. After January 2013, all
operating systems have this antenna connector. In this case, the dealer/installer can directly connect
the antenna to the operating system (the antenna is supplied with the remote control)
Below is the picture of the operating system including the antenna connection.

5.2.4 Programming the remote control (calibrate/pair)
Step 1
In order to pair the remote control to the system, remove the fuse (30Amp.) in the
cable assembly of the hydraulic levelsystem.
Step 2
Press the buttons “AUTOMATIC MODE” (no.7) and “RETRACT ALL JACKS” (no.8)
simultaneously.
When done, the Indicator LED (no.14) with the surrounding 4 arrows starts blinking
GREEN/ORANGE rapidly. This means the remote control is looking for its receiver,
mounted within the operating system.
Step 3
Reconnect the fuse to the system.
- The pairing process should be made within a certain time (apr. 20 sec.)
- The remote control turns off automatically.
- When the Indicator LED (no.14) goes off, the pairing process is complete.

Remote control (continued)
5.2.5 Putting the remote control into use
After programming the remote control you now have the possibility to operate the levelsystem with it.
Step 1
Switch the remote control ON by pressing button “ON / OFF” (no.5) for at least
1 second.
Now the GREEN LED will light up by flashing. As long as you see this LED flashing, the
remote control is searching for contact with the operating system. When contact is made
the flashing stops.
The illumination of one, or two, ORANGE arrows on the indicator LED (no.14) central on
the control panel shows the position of the caravan.
In the unlikely event that the caravan is already level, then the indicator LED (no.14)
lights up GREEN.
Further operation goes as described in the chapters 4.1 up to 4.3
5.2.6 Which device takes command
The device which is switched on first (remote control or control panel) takes the command to control
the system, until that device is switched off. If you would like to switch from one control device to
another, you need to switch off the power from the device that was in operation first.
REMARK 1: In the event of switching over from the remote control to the control panel: you have to
wait a little time, to give the system enough time to switch off contact between the remote control and
the operating system.
REMARK 2: It may be that the operating system is built in such a way that receiving a signal between
the remote control and the operating system works poorly or even not at all (caused by caravan
construction materials e.g. steel, wood, plastics, etc.).
In this case there is a possibility to move the antenna away from the operating system by means of an
optional extension cable (length max. 2 meters, available from E&P Hydraulics).
5.2.7 Battery Indicator
When the battery level indicator LED (no.15) lights RED, the device does not stop working
immediately. After this signal it is possible to use the remote control apr. another 4 times.
Make sure there is a spare battery in the caravan.

5.3 Emergency pump (optional)
5.3.1 Introduction
The optional Emergency hand pump allows the levelsystem to be operated manually, in the
(emergency) event the system is defective, or (more likely) because there is not enough battery
voltage present.
This possibility is offered by E&P Hydraulic for situations where, for whatever reason, the levelsystem
does not withdraw its support jacks and is therefore preventing you from driving, or moving, the
caravan.
We call it an "emergency situation" because in practice the time for withdrawing the hydraulic jacks is,
most often, also the time of a (planned) departure. By not automatically withdrawing the support jacks
you can no longer move, with adverse consequences.
Therefore, E&P Hydraulics offers you the possibility to integrate an emergency hand pump, for the
levelsystem. As the name implies, it is a pump operated by hand that controls (the withdrawal of) all
jacks. This means that the time of your departure, transport or movement can be guaranteed.
The emergency hand pump is mounted under the caravan in such a way that it is accessible from the
side.

Step 1
Using the Allen key, turn the gold hexagon bolt on the emergency hand pump
clockwise to the right (open position).
Step 2
Place the metal tube (handle) into the black holder on the emergency hand pump
assembly.
Pump (back and forth) with the metal tube until all hydraulic jacks are withdrawn.
(all jacks will be withdrawn at the same time)
The moment you feel pressure (resistance) building up during this movement is the sign
the jacks are fully withdrawn.
Step 3
Remove the metal tube from the holder.
Step 4
Using the Allen key, turn the gold hexagon bolt on the emergency hand pump
assembly carefully, anticlockwise, to the left until it locks (closed position).

7. Remarks and recommendations
Below is an overview concerning remarks and recommendations (tips) for the hydraulic levelsystem:
• After 4 minutes of no operation, the system will switch off automatically.
• The automatic levelling cycle can only be started after all jacks have been retracted. If the jacks are
not retracted when the automatic cycle starts, the system will do this automatically. So it is not
possible to make short adjustments to the jacks; the system will always first completely retract its
jacks.
• At a low battery voltage, the system will automatically switch off.
• All normal functions of the system are switched off, in error mode.
• During winter conditions (e.g. in snow and ice) put something (e.g. a piece of carpet) under the
jacks to avoid sliding.
• Manual operation is mainly recommended for uneven surfaces.
• The system cannot handle all angles, the limit values differ per caravan.
• If the system makes a slope angle that is too big and no longer responds to requests for automatic
levelling, we recommend bringing the vehicle as close as possible to the zero point in manual mode.

8. Troubleshooting
In case of an error message, check or the caravan stands not too high at the front (front wheel must be
withdrawn), whether the battery has sufficient voltage, whether the oil level is correct, whether there is
any damage to the jacks, and check all the cables.
If this does not lead to a solution for the fault, the fault could be located in the drive units. As the drive
unit does not have any repairable parts, you should contact your E&P Hydraulics dealer/installer.
Under normal circumstances, all LED’s are off and the unit will only respond by pressing the button
“ON / OFF” (no.5) switching the levelsystem on.

9. Maintenance
The E&P Hydraulics levelsystem does not have parts that need to be maintained periodically. When
parts have been taken apart, the warranty will become invalid. If necessary parts could be substituded,
repaired and/or exchanged (warranty). Please contact your E&P Hydraulics dealer/installer if
necessary.
WARNING: In control/service-works secure the caravan by placing suitable stands under the caravan.
By not doing this you create a real danger of personal injury or serious accident.
Preventative controls
• Periodically checking the hydraulic oil level. (ONLY by dealer/installer)
• The hydraulic oil (type: Pentosin CHF 11S ) preventative replace after apr. 36 months.
• Periodically check the electronic cables and connections.
• Periodically check the hydraulic jacks.
• Remove dirt, sand, mud and other contamination that settles during use, it may obstruct the
operation of the hydraulic leveling system.
• If the jacks remain extended for a longer period of time, the exposed legs should be protected
by spraying them with a silicon lubricant, to help prevent corrosion. If the caravan is located in
a salty environment, this should be done regularly.
• In winter (slippery) conditions we advise you to take additional safety and precautionary measures.
Especially because your safety during operation of the system. For optimal performance under
extreme conditions (- 30 degrees) we recommend the use of a special hydraulic oil for low
temperatures (consult an authorized dealer).
Furthermore, during the winter period we have to deal with situations in which de-icing salt will tack to
the outside of the system. Preventative maintenance should be:
• Good cleaning of the jacks.
• Clean the stainless steel cylinder (piston rod) and spray with a silicone lubricant.
• Remove dirt from the stainless steel foot plate (especially at the bottom, this is the area your
caravan stands on)
• Try to put the caravan in a location as clean and flat as possible.
• Place a piece of rubber (e.g. piece of carpet) between the frozen (slippery) surface and the
the footplate.
• Before leaving make an additional check round the caravan, if necessary remove snow and
ice from the jacks, then you are free to withdraw the jacks.
