I. INTRODUCTION
he RICON Titanium™S-Series®and K-Series® Public Use wheelchair lift provides wheelchair access to vans and
buses. The patented movement provides smooth, safe entry and exit and lifts up to 1,000 pounds (454kg). It is
to be operated by a trained attendant. The lift contains a powerful electro-hydraulic pump that includes a built-in
manual backup pump. If the lift loses electrical power, it can be raised or lowered manually.
By using the lift control switches, the lift is unfolded out from the vehicle (deployed). The user boards the large non-skid
platform and the operator uses the control switches to gently lower the platform to the ground. After the user departs,
the platform is raised and folded into the vehicle (stowed). The lift is also available with a platform that splits and folds
when stowed, providing easy vehicle access through the lift.
This manual contains installation instructions; maintenance and repair instructions; troubleshooting guide; parts and di-
agram lists. It is important to user safety that the lift operator be completely familiar with the operating instructions.
Once the lift is installed, it is very important that the lift be properly maintained by following the Ricon recommended
cleaning, lubrication, and inspection instructions.

II. INSTALLATION
his chapter contains instructions for installing the Ricon Titanium™S-Series®and K-Series®Public Use wheel-
chair lift into most vans and busses, although custom installations are also possible in other types of vehicles.
Due to the wide range of lift applications, specific information for every possible application is not available. The
following general procedures will apply to most installations. Contact Ricon Product Support for instruction concerning installations
not covered. To install lift, refer to following sections and perform procedures carefully and in the order that they are presented. Be
certain that installation instructions are followed exactly and do not eliminate any steps or modi-fy product.
NOTE: Please review carefully the installation instructions (32ii463e) that are supplied with this lift before beginning the
following procedures. Where theseprocedures conflict, the installation instructions take precedence.
Public use vehicle manufacturers are responsible for complying with the lift lighting requirements in Federal
Motor Vehicle Safety Standard No. 404, Platform Lift Installations in Motor Vehicles (49 CFR 571.404)
A. GENERAL MECHANICAL INSTALLATION
1. LIFT LOCATION
The installation surface must be flat and level. It is recommended that lift be installed on a ½", minimum, high-grade plywood
sub-floor. However, this additional installation height may not be acceptable in cases where over-head clearance is limited.
Refer to Figure 2-1.
NOTE: Check for proper travel clearance through doorway.
a. With doors fully open, place/position lift in vehicle doorway as close as possible to door, with lift's baseplate assembly
parallel to side of vehicle.
b. Allow a distance of 3/4", if possible, between door and the part of lift closest to it. Adjust lift left and right-side locations
to accommodate subframe members.
c. Verify proper clearance of door frame, passenger seats, and outer edge of vehicle floor and possible inter-ference with
wires, fluid lines, subframe members, etc.
2. VEHICLE DIMENSIONAL REQUIREMENTS
The following figures and text provide installation guidelines for the RICON Titanium S-Series and K-Series Public Use
wheelchair lift into most vans and busses. Adherence to these requirements will verify that the lift installation conforms to the
requirements of FMVSS 403 and 404.

b. VEHICLE FLOOR STRENGTH REQUIREMENTS
NOTE: The Ricon Titanium™model lift structure has been bench tested to four (4) times its rated load. Con-
sistent with the requirements of FMVSS 404, Ricon recommends that the vehicle structure be tested to
three (3) times the rated load of the lift (3,000 lbs.) to ensure sufficient capacity exists in the
NOTE: The Ricon Titanium™lift is shipped with a 1,000 lbs. capacity rating. Ricon understands that the 1,000
lbs. rating is not required to meet the minimum requirements of FMVSS 404. In the event the aforemen-
tioned recommended test load for the Titanium™lift cannot be met, the vehicle manufacturer may de-rate
the installation to 800 lbs. using new decals available from Ricon (Ricon P/N 26201).
NOTE: The table below illustrates the reaction forces present when the lift platform is loaded to three (3) times
the rated capacity or three thousand pounds (3,000 lbs.)

FIGURE 2-2: FLOOR STRENGTH REQUIREMENTS
3. LIFT INSTALLATION GUIDELINES
The lift mounting is a very important step. Improper mounting or fastening of baseplate can adversely affect lift per-
formance. Although fastening details may vary from one vehicle to the next, these general principles apply:
Be certain that all mounting bolts are properly installed and tightened. Bolts used to fasten baseplate assembly
to vehicle floor must have a minimum strength rating of SAE Grade 5 and be torqued to 28 ft lbs, dry. Recog-
nize that the most important bolts are those along the rear of lift, since these bolts retain the majority of the
load.
Refer to Figures 2-3 and 2-7. Improper torqueing sequence of baseplate bolts may result in a warped or
bowed baseplate, which can cause platform to move erratically.

CAUTION
Before drilling holes, verify that underlying wires and tubing will not be damaged.
c. Fasten Lift:
1) Insert ten 4" x 3/8" carriage bolts through baseplate and vehicle floor.
2) Refer
to Figure 2-9. Install five clamping bars on bolts underneath vehicle floor (across baseplate), i.e.,
from 1 to 6, 2 to 7, etc, and secure lift to vehicle floor with 3/8" washers, lock washers and hex-nuts.
3) Use care when tightening carriage screws to prevent baseplate warpage. If baseplate assembly warps,
vertical arms will not be parallel. Make corrections by shimming at appropriate locations. To help pre-
vent warping, tighten the eight carriage bolts to 28 ft. lbs. in the following sequence:
3, 8, 2, 4, 7, 9, 1, 5, 6, 10
NOTE: Vertical arms must be parallel for proper operation. Adjust bolts as required. Best results are obtained
when lift is mounted on plywood. Shims, although best avoided, may be used if required.

1. INSTALL MAIN CIRCUIT BREAKER
a. Disconnect battery.
b. Mount main circuit breaker inside engine compartment within 12 inches of battery (to minimize length of un-
protected cable). Avoid installing near a heat source.
2. ROUTE AND CONNECT MAIN POWER CABLE
CAUTION
Check under-side of vehicle before drilling to avoid damage to fuel lines, vent lines, brake lines, or wiring.
NOTE: For applications where power cable is to pass through sheet metal, drill a 3/4" hole and use wire clamp pro-
vided. For applications where cable is to pass through plywood, drill a 1" hole and use black plastic grom-
met provided.
a. Refer
to Figure 2-11 and 2-12. Drill a hole through vehicle floor near positive connection block so power
cable can reach stud of positive connection block. Drill hole where the installed pump cover will cover it.

b. Refer to Figure 2-11. Install supplied heavy ring terminals to each end of the short (12" long) 4 AWG pow-
er cable. Install one ring terminal, only, to one end of long power cable. Use an appropriate crimp tool
(such as Ricon hammer tool, part of kit P/N 01243).
c. Connect ring terminal end of long 4 AWG power cable to 90A main circuit breaker, then route power cable
underneath vehicle floor and up through hole in floor.
d. Refer
to Figure 2-11. Detach Kit P/N 37152 (Shipped with pump handle) then install onto ring terminal
connector before installing ring terminal onto positive connection block.
e. Tie power cable to vehicle chassis, and to pump assembly harness using cable ties. Avoid pinch points,
exhaust system, moving parts, and brake lines. Verify that power cable is secure.
CAUTION
Be sure that there is no interference with any parts that
could damage power cable or other wires in any way.

g. Refer to Figure 2-11. Connect 12" cable, with ring terminals, from positive battery terminal to main circuit
breaker terminal.
3. GROUND CONNECTIONS
a. Refer
to Figure 2-13. Locate 4GA vehicle chassis ground cable that is pre-installed then install ground ca-
ble to vehicle chassis. Avoid pinch points, exhaust system, moving parts, and brake lines. Verify that
ground cable is secure.
b. Ensure other wires that are fasted with the ground cable are secure and remain connected after installation.
c. 12 VDC Systems
12 VDC powered lifts are chassis grounded and do not require a separate ground cable connection to bat-
tery. However, if the common side of the lift electrical system is connected to chassis with a cable, the ca-
ble must be attached in a manner that provides a reliable electrical connection. If ground cable is attached
to an existing ground circuit, the circuit must be capable of conducting an additional 90 amps.
4. CONTROL PENDANT
The water resistant control pendant can be connected on either the left hand or right hand side of the
wheelchair lift. Connections for the control pendant are located on the pump chassis, close to the connec-
tion block. An alternate control pendant connection is located opposite the pump chassis, near the stow
lock cover. CAUTION
Only one control pendant can safely operate the
wheelchair lift at any time. Use of more than one control
pendant at the same time is not permitted.
a. Press Power switch to OFF position on control pendant. Illuminated lights will turn off.
b. Refer to Figure 2-14. Locate control pendant connector installed on pump chassis side of wheelchair lift.
c. Twist and unlock connector then remove from pump chassis.
