    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.
  • Page 5: Motor And Connecting Shaft

    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.
  • Page 6 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"...

  • Page 10: Slotted Lower Trolley Tab Bracket Installation

    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.
  • Page 11: Automatic Bunk Lock-Up System Option

    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.
  • Page 12 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.
  • Page 13: Wiring The System

    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.
  • Page 14: Relay Control Module

    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.
  • Page 15: Testing The System

    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.
  • Page 17: Limit Switches - Microswitches

    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.
  • Page 18: Relocating Limit Switches

    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.
  • Page 19 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.
  • Page 20: Manual Operation

    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.
  • Page 21: Manually Lowering The Bed(S)

    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.
