Safety This manual provides general instructions. Many variables can change the circumstances of the instructions, i.e., the degree of difficulty, operation and ability of the individual performing the instructions. This manual cannot begin to plot out instructions for every possibility, but provides the general instructions, as necessary, for effectively interfacing with the device, product or system.
Preparation Resources Required • One to two people, depending on task • " Allen wrench • Phillips screwdriver • Tape measure • " Wood or self-tapping sheet metal screws (OEM-supplied) Pre-installation The bed lift frame (Fig. 1) must be installed squarely at the same height side-to-side and at the same distance from front-to-back in the unit, with vertical rails parallel side-to-side.
The 1/4" wood or self-tapping sheet metal screws (OEM-supplied) must be used in all large holes of the vertical c-channel rails, including the large double mounting holes at the top (Fig. 2) and bottom (Fig. 3) of the rails, to prevent rail-twist. Fig.

Make sure that the drive (lower) trolleys (Fig. 8A) are at the same height on both sides of the bed lift. Install connecting shaft by sliding open end of shaft over the hex shaft on the side opposite the motor (Fig. 9). NOTE: If a gap forms due to the timing shaft "walking"...
Upper Trolley Tab Bracket Line up the holes in the gold-colored spacer block (Fig. 11A) and trolley tab bracket (Fig. 11B) with the holes in the upper trolley (Fig. 11C). Secure the trolley tab bracket and spacer block to the upper trolley with the included screws (Fig.
Standard Lower Trolley Tab Bracket NOTE: The standard lower trolley has four holes. The trolley tab bracket and spacer block can be installed in any two holes on the lower trolley. Line up the holes in the gold-colored spacer block (Fig. 13A) and trolley tab bracket (Fig. 13B) with two holes in the standard lower trolley (Fig.
Slotted Lower Trolley Sofa/Dinette Bracket The sofa/dinette brackets are not designed to bear the weight of the furniture. Any furniture installed on the brackets MUST have the proper support legs attached to the furniture frame. When extended, the furniture support legs should be within "...
Slotted Lower Trolley Tab Bracket Installation Slotted lower trolley tab brackets can be installed in place of the sofa/dinette brackets if a lower bunk configuration is required. NOTE: There are four slots in the lower trolley. This trolley tab can only go into the top slots and can only be installed with the trolley tab at the top.
Automatic Bunk Lock-Up System Option The Automatic Bunk Lock System utilizes a lock-up mechanism to push the upper trolleys into spring- backed brackets (Fig. 17) inside the C-channels so the upper trolleys do not drift downwards. The brackets come already bolted into the C-channels (Fig. 18). Fig.

Locking the Upper Bunk Trolleys If the lower trolleys have a have a sofa or dinette attached, rotate the seatback(s) to the horizontal position. Flip the locking mechanism tab (Fig. 20A) so the long portion of the tab is outside of the C-channel. Repeat for the other locking mechanisms.
Wiring the System Connect 12V DC and ground from the unit's power supply to the motor's location with 10 AWG (2.59 mm) stranded electrical wire. Connect a 12V DC line to the solid white wire of the supplied power pigtail and the ground wire to the black striped wire of the pigtail (Fig.
Place the BED LIFT CONTROL switch (Fig. 26) over the hole and secure it with the screws provided. Make sure the switch is positioned such that both screws will securely hold the switch in place. Fig. 26 Switch Mounting Screws Relay Control Module All outputs are marked on underside of the relay control module (Fig.
Testing the System Trolley Travel Moving parts can cut or crush. Keep clear of moving parts. This test requires two people. Each time the micro-limit switch is depressed the drive trolley should stop. If the trolley fails to stop when the switch is depressed, re-check all electrical connections and 12V DC and ground wire connections.
Check to make sure that the wires punched down into the microswitch connectors (small red ones) are tightly secured. If necessary, press wires firmly in-place with a small screwdriver blade (Fig. 27) to make sure that the pins in the connector bite through the insulation on the wire. Fig.
Limit switches - Microswitches The limit switches are no longer active in the circuit and will not stop the bed. Damage to the switches, mechanism, or unit could occur. Reversing the wire leads will reverse the motor direction. To determine if there is a limit switch problem, eliminate the switches from the circuit. Remove the small 3-pin and 2-pin red limit switch from the relay control module.
Relocating Limit Switches If desired, the limit switches can be moved from their factory locations to one of the alternate positions. To relocate the upper limit switch: Remove the two Phillips head screws (Fig. 34A). Fig. 34 Move the switch to the new location. NOTE: It may be necessary to add 6P4C (28 AWG) electrical wire to the microswitches to accommodate switch relocation.

To relocate the lower limit switch: Remove the two Phillips head screws (Fig. 35A). Fig. 35 Move the switch to the new location. NOTE: It may be necessary to add 6P4C (28 AWG) electrical wire to the microswitches to accommodate switch relocation.
Manual Operation When bed(s)s/are not being manually raised or lowered, the brake MUST be set or the bed(s) will drift down, causing possible personal injury, product or property damage. Moving parts can cut or crush. Keep clear of moving parts. Before releasing the brake in manual mode, make sure there are no obstacles below the bed(s), sofa or dinette.
Remove the caps from the cranking points (Fig. 38A), which are located at the top of the front C-channels (opposite of the C-channels where the motor and cross-connecting shaft are installed). Using a 1/2" socket wrench, manually crank the bed lift. NOTE: Cranking is easier if two people crank simultaneously, one on each side of the bed lift.
