are installing may not look exactly like this. The

A/C track has a channel down the middle which

Regardless, the installation procedures are alike for

all Citia and Aveya models.

If you change the unit to Left Hand, you will need

to change a plug on the unit. Information for hand

changing on the unit can be found on page 10.

B. INSTALL MOUNTING HARDWARE

Lay out the sections of track on the staircase, with

the back side facing up.

 Insert the appropriate number of T-bolts into the

slots on the bottom of the track.

Note: There will be three (3) brackets per each 8’ sec-

tion. This must be done before the splice bars

can be inserted.

 Assemble the mounting brackets on the T-bolts as

shown.

 Slide the (2) pieces of track together and secure

the splice bars with the set screws. Ensure that a

tight, hairline joint is formed all the way around the

track joint.

Note: Snug the bolts, but do not tighten at this time

as the brackets will need to be adjusted.

Load the loose 38” piece of gear rack from the top, and

slide up to meet the other gear rack. Time and tighten

gear rack.

Turn the track assembly right side up on the stairway.

A short piece of gear rack is

provided in the small parts

kit to properly space the gear

rack splices.

Do not tighten gear rack until the

proper spacing has been achieved.

There may be a gap between two pieces of gear

rack when spacing the splice. This is acceptable

as long as the distance between the teeth is

consistent.Thiscanbeveriedbymatchingthe4”

piece of gear rack to the splice.

Area able to be omitted in

Use the 4" piece of gear rack included in the small

parts kit to time the gear rack.

Tighten the pieces of gear rack down in place.

Note: There is not a top or bottom end of the gear rack.

D. INSTALL LOWER END CAP

Slide one T-bolt on the gear rack side of the track.

 STEP MAY NOT APPLY TO YOU: Slide 1 T-bolt on each

T-slot ONLY in installations where track does not touch

theoorofthebottomlanding,suchaswhentrackstops

onrststep.Ifthetrackwillberestingontheoor,skip

this step and proceed to step 4.

Slide the end cap onto the lower end of the track,

inserting the dove tail into the groove on the top of the

track.

Note: If you skipped step 3 because of the type of

installation you are performing, skip step 6 as well.

Fasten the end cap to the track with the T-bolts and

nuts provided.

E. MOUNT TRACK TO THE STAIRCASE

Snap on the track mounting bracket covers.

Lightly lubricate the entire length of gear rack.

Lubricant is provided in the small parts kit.

Position the track on the staircase with the bottom side

of the track resting across the stair nosings, the lower

track end cap resting on the lower landing, and the

back side of the track 3 ½” away from the wall or other

obstructions, such as the power supply. If installing a

Citia Silver or Aveya Premier this distance will need to

increase to 6 ¼" to accommodate the wider seat.

Note: These instructions are for mounting to a standard

wood staircase. For installation on hard surface

stairs, anchors may be needed and different screws

may be required.

Note: This distance is needed for clearance of the seat

back in the riding and swivelled position.

Attach the track to the staircase with track mounting

brackets. The brackets attach to the stair treads

with wood screws. Locate one bracket at each of

the following positions:

 1st tread at the bottom of the

stair

I. INSTALL THE CHASSIS ASSEMBLY INTO

THE TRACK

 NOTE: If you will need to change remote frequencies on

the call/send remote controls do this PRIOR to mounting

the chassis on the track. With the chassis close to the

wall,itmaybecomedifculttoremovetheshroudand

access the control board. Refer to Step C of the Service

Information for instructions on changing the frequency

of the remote control.

 Measureforthelenghtoftheexchain.Theexchain

should be the same length as your track. If it is too long,

snap the chain at the correct link and discard the excess

plastic links.

 Move the chassis to the top landing. Do not pick up

by the plastic shroud. Remove the front seat mounting

cover. You must remove the screws from the back

side of the cover rst.

From the factory the A/C unit will be Right Handed. To

change the handed-ness of the unit remove the cover

from the footrest/seatpost area.

It should look like this:

There will be two harnesses, one marked RH (right

NOTE: Make sure to retain last link with chain mounting

clip. You WILL need it later.

Once you've started the Flex Chain into the channel,

slide the unit on to the track, using the guide wheels

to help put the track in place. From the bottom of the

chassis, the unit should look like this:

Line up the splice bars of the starter track with the top

end of the track bolted to the staircase.

While holding the chassis, remove the long bolt from

the starter track and gently slide the unit down the track

until the chassis is fully on the mounted track and the

gears have engaged.

L. INSTALL JUNCTION BOX

Determine where, underneath the track, you’ll be

mounting the junction box. Route the power wire

from under the end cap, down the center of the

underside of the track to where the box will be. Give

yourself an inch or two of slack and strip back the

wires.

The junction box will come from the factory

pre-wired to the Edison Plug that goes to the wall.

You will have to wire the grey power wire from the

Flex Chain.

All needed connectors are supplied in the

junction box.

Insert the grey wire and connect these ends on the

wires:

Note that there are two black wires. Their jackets are

labeled L1 and L2. It DOES matter which one goes

where.

Now make the connections. There are six wires total

in the junction box, three coming in from the track,

and three going out to the plug in the wall. Below is

a chart to help you double check your wiring.

From Grey Cable Should be connected to:

Black wire (L1) Top Circuit Breaker

Black wire (L2) Wire nutted together with

pliers come in especially handy here.

Slide a T-bolt down each side of the track. Attach

the Junction box to the track using two T-bolts and

two nuts.

Plug into the wall.

K. INSTALL THE TOP END CAP

Route the power wire

out through the

bottom of the end

cap.

IT IS CRUCIAL

that the power

wire fit into the

recessed area of

the end cap on

its way out. If it

is anywhere else

the wire will pinch

and may possibly

short out.

Notes:

• The call/send controls (transmitters) use infrared signals.

There are two infrared sensors located on the chassis

access cover. There is a combination of 4 different fre-

quencies the transmitters can be set to (both transmitters

must be set to the same frequency).

• There is a half second delay after a control button is

pressed before the lift starts to move. After the lift stops,

the up/down controls are disabled for 3 seconds.

Safety Devices:

Warranty: Five years on drive train (motor and gear)

Two years on all component parts

Caution!

The control board is sensitive to static charge. To avoid

damage, touch a metal surface on the lift to discharge

yourself of static charge. Never touch the chips on the

control board.

Always disconnect the 115 VAC power when working

on the lift.

Remote Control (Transmitter) Frequencies

The standard wireless remote controls (transmitters) use

infrared signals. One button on the transmitter is UP and

other button is DOWN. There are two infrared sensors

(receivers) located on the chassis access cover.

A combination of 4 different transmitter frequencies allow

for more than one lift in a single home. The two transmit-

ters must be set to the same frequency (for each lift). For

example1to1,2to2,etc.

To change a frequency:

Ensure the infrared receivers (in chassis cover) are con-

nected to the control board. Use the seat control to move

the lift away from the end of the track. Take the back off of

ter) to the same code. Change the corresponding code in

the control board J1 (see chart). Press and hold the yellow

"learn" button on the control board, then press and hold

one of the up/down buttons on one of the transmitters. The

controller board should beep and the lift start to move after

you release the transmitter button when the frequency has

been successfully changed.

Note that if the lift is on an upper or lower limit switch, the

frequency may not be able to be changed.

To access the controller board the footrest support and

shroud must be removed. The footrest plug can be tempo-

rarily jumpered out while changing frequencies.

D. CONTROL BOARD DIAGNOSTICS
