Note: Modication of any factory supplied item may result in the denial of all warranty claims.
Call Equalizer Systems Technical Support prior to any modications.
With any hydraulic application, holding position on a cylinder must be done with safety in mind. Failure in
the system may cause the jacks to retract or extend suddenly. When working under or near the coach, always
use jack stands of appropriate rating to support the weight of the coach.

Jacks
Reference Chart for Installing Jacks
• The jacks will have to be bolted to the brackets using 1/2” diameter fasteners, min. grade 5.
• The jacks must be mounted to the chassis frame as close as allowable to the front and rear axles.
• The jacks must have a minimum of 6 inches from the ground with the foot pads no lower than
anything on the coach. Retract the jack fully, and determine the ground clearance by measuring to
the bottom of the jack foot.
• Make sure that the foot pads on the rear jacks are inside the angle of departure.
• The foot/pad must be mounted within range suggested (see chart below) for proper operation of
the system.
• For some they can be directly bolted to the existing mounting brackets or structure.
• For some the brackets may need to be welded to the frame, to which the jacks can be bolted.
• For some square tube jacks they may need to be welded directly to the frame or structure.
Due to variables with the different vehicles and jacks involved, the placement and process
(Bracket welding, Square Tube Welding) of the jack brackets likely will be on a case by case basis.
If there are any questions, please call Equalizer Systems (800) 846-9659.

SL 18, SL 16 and SL 15 Leg Assemblies
This assembly utilizes the 3/4” Flat Head Allen Bolt, 3/4” X 1 1/4” FHSCS - Equalizer part # 1383.
Required for installation:
• Brush and solvent to clean threads
• Blue Loctite
• 1/2” drive impact gun
• 1/2” drive X 1/2” Allen Hex socket
• Compressed air source and air blow gun
See drawing on next page.
1. Using solvent and brush, clean out the threaded hole in cylinder rod end (there may be grease
in this threaded hole for corrosion protection during storage/shipping. This grease or corrosion
protection must be cleaned out prior to installing the foot). Use compressed air to dry.
2. Apply liberally, blue Loctite to threads of cylinder rod or bolt (part # 1383).
3. Hold foot pad in place at end of cylinder rod with the cupped end to the cylinder rod.
4. Insert the bolt (part # 1383) through the hole in the center of the foot pad into the threaded end of
the rod. Turn clockwise by hand to start (you may use the 1/2” Allen bit to help). Be sure that the bolt
starts in straight and is not cross threaded.
5. Using the 1/2” Allen drive bit and 1/2” impact wrench/gun, tighten the bolt into the rod. Allow the
impact wrench to impact/drive the bolt totally to full depth. Note that the cylinder rod will/may rotate as
you do this.
Process
• When completed the foot is not intended to be tight. It is designed to pivot slightly and will be free
to rotate when the cylinder is slightly extended.
• There is a “foam” cushion or damping ring that is attached to the bottom of the cylinder body
with adhesive. Its only purpose is to keep the foot from rattling when fully retracted. If it comes
loose/falls it may be glued back up to the bottom of the cylinder or it may even be removed.
Replacement part number for this ring on SL 15 and SL 16 is part # 1800. Replacement part
number for the ring on SL 18 is part # 1799.
• Some cylinder rods may have a rubber ring around them that may stick to the rod as it is
extended. This is a protection ring that is used in production to keep paint from the rod and lower
seal area. It may be ignored or removed; it has no other use. Its presence, or lack of, is not a
defective component.
Notes
Foot Installation for SL style jack Leg assemblies

6
SL 13 Leg Assembly
This assembly uses the 3/4”-16 nylock jam nut.
Required for installation:
• 1/2” drive Impact wrench/gun
• 1/2” drive X 1 1/16” socket (6 point preferred)
Process
1. Check/verify that the threads on the end of the cylinder rod are clean and not damaged. Use the
nylock nut to check that it will thread (start) on the end of the rod. Do not fully install or tighten at this
time. Remove the nut.
2. Position the hole in the middle of the foot pad over the threaded end of the rod. Start the nylock nut
onto the threads by hand.
3. Using the impact wrench/gun and the 1 1/16” socket, tighten the nut onto the rod. Note that the rod
may rotate as you are doing this. Tighten the nut until between 1 and 3 threads are visible past the
end of the nylock nut.
Notes
• When properly installed, if the cylinder is extended slightly, the foot should pivot slightly and will be
free to rotate.

Pump
Fittings
Hose
Use the 3/8-16 threaded holes in the base of the pump assembly for mounting.
When installing the pump on the coach the location should provide access to:
• Route the hydraulic hoses to the manifold.
• Fill the reservoir and monitor the ll level.
• The cartridge valves and the end of the motor in case manual override of the system is required.
Install the hydraulic adaptor ttings in the top and bottom of each jack and install the ttings into
the manifold.
• The straight thread O-ring side always goes to the cylinder or manifold.
• The tapered side will get the hose attached to it.
• When installing straight ttings into the leg or manifold, tighten to 15 lbs-ft. When using 90-degree
ttings, turn until nger tight, position correctly, then tighten the jam nut to 15 lbs-ft.
Install the hydraulic hoses
according to the chart.
• Route the hoses clear of all hot
exhaust components and pinch
points in the suspension/chassis
system.(moving objects, sharp
edges and high heat sources)
• Attach the hoses to the manifold
and jack ttings.
• Tighten to 15 lbs-ft. Secure the
hydraulic hoses with wire ties or
loom clamps to the chassis.
• Care should be taken to not kink
or twist hoses.
• The min. bend radius is 6 inches.

Wire harness
Route the wire harness from the pump assembly to the area where the control panel is to be mounted.
• The harness needs to be routed away from moving objects, sharp edges, and high heat sources.
• Use wire ties and/or loom clamps to secure in place.
• The end with the 9-pin and 2-pin connector goes to the pump assembly. (See the drawing for the layout.)
• Connect the harness connectors to the matching connectors at the pump assembly.
EQ Smart-Level Control Panel
Fasten control panel (vertically or horizontally) in desired location.
• It may not function well right at 45 degrees.The most accurate will be right at horizonal (0 degrees)
or vertical (90 degrees).
• It may be mounted on any surface regardless of its orientation to the front of the vehicle
Examples: on the center console, vertical wall, cabinet wall or other rm structure.
• The control panel is not waterproof therefore it must be in an interior location or compartment
protected from the elements and spill areas.
• Attach the supplied wire harness between the Control Panel and the location of the pump assembly.
• There are two connectors, one is a 12-pin double row and the other is a 3-pin, which is the power
and ground feed for the control panel.
• There may be additional optional connectors that are not used for most installations. There may be
additional wires breaking out of this harness, they are discussed on page 10 in chassis interface.
• The control panel must be rmly mounted to a surface that ‘reacts’ with the coach during leveling.
The Auto Level function requires this as the leveling sensors are located inside of the control panel.
A set up process known as Orientation Program followed by setting the Null
(described later) must be performed. If these steps are not completed the Auto Level function will not
operate properly. See orientation and null settings for these processes.

ChaSsis Interface Connections
The below items are designed primarily for motorized vehicles. When installing on a trailer the Ignition
disable is not required and the wiring may not be present in the supplied harness.
• If the pink wire is present, just tape it back.
• If the black/yellow wire breakout is present it will need to be connected to a ground source (this is
pre-connected to ground inside of many harnesses designed for trailers).
It is possible to use these disables on a trailer as an interlock that will prevent extension operation, but this
is not required for most installations. The use of these “interlocks” is at the discretion of the trailer/vehicle
manufacturer. Call Equalizer Systems for further information.
Step 1 - Keypad Ignition Disable Circuit
Step 2 - The Black/Yellow Wire Must Receive a Ground Input
Step 3 - Optional Park Brake Connection for Black/Yellow Wire
• Note the “break-outs” near the end of the keypad harness. The Pink wire must receive a +12 VDC
input when the ignition key is in the “on” position.
• Connect this wire to the ignition positive. This will make the wire “hot” and will prevent jack
extension when the vehicle ignition key is in the on (engine run) position. This also provides for
a “jacks down” warning in the event of a jack drifting from the stowed position during travel. This
connection is required on motorized vehicles.
• Failure to make this connection may create an unsafe condition and may void the warranty
(on motorized units).
Contact your chassis manufacturer to verify park brake chassis connection and location.
This connection must be done by a technician qualied for chassis electrical systems.
• Most chassis manufacturers are now doing this through the Dash Module. Attempts to connect
this improperly could lead to dash feedback or other issues.
• This connection to a park brake signal is optional. If this input is not connected to the park brake
signal or to ground, Auto Level will be continuously denied.
• Also, the engage park brake light will be on if the panel is powered up or the key is in the on
(engine run position).
• This black/yellow wire must be connected to a chassis ground.
• If this wire is not connected to ground, the Engage Park Brake light will be on and Auto Level will
be Denied.
Please note that Step 1 and 2 are required on motorized units.
Step 3 is optional and generally is only used on motorized units
