Up to approximately 5% or 3°.

However, this question has no hard and fast rule due to several variables such as the make and model of the caravan. For example, the distance between jacks fitted on the axle, the stroke of the caravan jack and the available stroke of the AL-KO big foot corner steadies. 

E&P advise that you can not auto-level on a gradient higher than 5%. However, this depends on variable factors such as the make and model of the caravan, the chassis weight and height and the nature of the slope. If needs be, you can use the manual function on the remote control, using the inbuilt level indicator and placing suitable wooden blocks at the relevant jacking points to aid tricky levelling situations, but be sure to site the blocks squarely under the footplates, to avoid damaging them.

Normal conditions = 11 amp + 1-2 seconds at 17 amp when over pressurising to ensure all jacks are fully retracted.

Extreme conditions (e.g. cold weather) = 17 amp.

It can take a maximum of 120 seconds, but often less than a minute.

The E&P Hydraulics levelling system requires a fully charged battery to operate. It is an auto levelling device requiring power, just like a fridge, heating system, or motor mover.

E&P Hydraulics system software is designed to protect the battery and, therefore, if the battery voltage is low then the hydraulic levelling system cannot be used and an alarm will sound on the control panel to indicate this. In the event your battery voltage is too low, you can hook up to the site electrics, or your towing vehicle to recharge it.

The E&P Hydraulics Level C system takes its power from the caravan leisure battery and it doesn't take much when compared to motor movers. Their system software is designed to protect the battery and, therefore, if the battery voltage is low then the hydraulic levelling system cannot be used and an alarm will sound on the control panel to indicate this. In the event your battery voltage is too low, you can hook up to the site electrics, or your towing vehicle to recharge it.

The warranty of the caravan manufacturer is not affected by the fitting of the Level C system. Caravan manufacturers fit corner steadies to their vans in line with guidance and approval from AL-KO, who supply the corner steadies. AL-KO have tested the E&P system and given their approval for the corner steadies in a report which determined that the Level C system actually prevents too much force being applied through the corner steadies, when compared to a standard corner steady, thereby helping to protect the floor of the caravan.

The E&P Level C system is compatible with all makes and model of caravan and is offered by various OEM’s as standard fitment, or as an optional extra, as well as being offered in the aftermarket only through their approved Partners, like TCC Services.

Whilst it is you, the user, who is responsible for ensuring the caravan is safe to tow, this scenario is nearly impossible because you would likely be unable to hook up the caravan to the tow vehicle with the jacks down. However, it is always good practice to walk around the caravan and visually check that all jacks are fully stowed before leaving site.

You can still auto-level or auto-retract the system from the touch panel housing in the event you lose or damage the touch panel. The touch panel has a long-life rechargeable battery that will automatically recharge as soon as it is placed back in the housing.

A replacement touch panel can be ordered from an E&P Hydraulics Accredited Partner if required.

No, it is a closed loop hydraulic system.

Yes, this is useful for protecting tyres during long periods of storage, but it will not completely stop tyre degradation. It can also help prevent a sticking handbrake and make the caravan more secure against theft. If you are leaving the system deployed for a long period of time, please use a silicon-based protective spray on the axle jacks to prolong their durability.

Yes, this aids the fit of wheel security devices greatly. However, you, the user, are responsible for ensuring the caravan is safe to lift and that it is adequately supported with axle stands if any work is being carried out under the caravan. Please do NOT work underneath a caravan if the only method of support is the E&P Levelsystem.
