This manual is a guide for the installation of the Schwintek Bunk Lift System. Exact installation procedure depends on RV manufacturer's design of bunk bed attachment brackets and surrounding structures. At RV manufacturer's discretion, the motor mounting blocks can be attached to either the seat back structure (Fig. 1A) or the wall structure (Fig. 1B). Mounting to the seat back structure will not conceal the gear teeth, however mounting to the wall structure will conceal the gear teeth.
1. Mount motor bearing blocks to load-bearing structure using (4) 1/4 -20 bolts per block. The mounting bolt pattern is shown in Fig. 2. Use the measurements provided to create a template for the bolt holes. TOP 2.175” Motor Bearing Block 4.500” Fig. 2 0.266” Ø x4 2.918” BOTTOM NOTE: Motor bearing blocks must be mounted in such a way to ensure the gear racks raise and lower perpendicular to the coach floor and parallel to walls.
3. Insert gear racks into motor bearing blocks by aligning V-grooves in the rack to the V-rollers in the motor bearing blocks. Insert until the gear in the motor bearing blocks comes into contact with the serpentine groove in the gear rack as shown below (Fig. 3). Fig. 3 4. Connect motors to controller and controller to 12v power source. NOTE: Type and location of Raise/Lower switch to prevent unsupervised and unintended operation is responsibility of RV manufacturer. 5.
7. Attach bunk bed mounting brackets and bunk bed to gear racks. NOTE: Bunk bed and method of attachment to the Bunk Lift System is responsibility of the RV manufacturer. Bunk bed must be centered on the Bunk Lift System’s gear rack lifting posts. Connect motors to controller and controller to 12v power source. NOTE: Location of Raise/Lower switch to prevent unsupervised operation is responsibility of RV manufacturer. PROGRAMMING 1. 2. 3. Homing the Bunk Lift for the first time: A.
