Summerlift Marine Cable lift for installation of a height adjustable Plasma TV lift

The Panasonic Plasma TV is to be located below counter top; within a Yard built cabinet built by cabinetmakers, contractors, and individuals  with reasonable mechanical skills. 

12 volt Summerlifts operate for a guaranteed 10,000 cycles with load capablities ranging from 160 to 600 pounds. * loads in excess of 225 pounds or more than 30" in width employ dual Summerlift cable lifts; loads in excess of 350 pounds use quad-Summerlift cable lifts.

The Summerlift Marine TV enclosure consists of: (i) a platform on which the TV rests; (ii) a sheet metal channel frame and mount that secures the TV during raising/lowering (The plasma TV secures to the Summerland mounting bracket enclosed within the metal channel frame); (iii) a slide mechanism at each end of the platform that provides for smooth up and down travel; (iv) a securing lock that provides for hold-down of the TV when underway; (v) two (2) Summerlift Cable drive units and control boxes.

  The TV unit raises and lowers with (12 v dc) raising/lowering controlled by  Summerlift Marine remote control and a manual switch (both are included). At the same time the TV is raised/lowered, a section of the countertop is also raised/lowered.

TV height positioning is precisely accomplished by the user to meet individual ergonomic viewing requirements. 

1) The Panasonic Plasma TV mounts on a platform (prox 6” x 42” x ¾”) extending between Summerlift brackets located at each end of the platform. Mounting holes are provided for securing of the platform with wood screws.
2) Summerlift brackets are mounted to two slides at each end (4 slides total). The slide assemblies are yard-mounted to the cabinetry utilizing conventional s.s. wood screws.

Summerlift™ Marine Plasma TV lift General Use Notes 

Getting Started: - - Outlines general utility of the Summerlift™ Marine Plasma TV lift for raising/lowering applications. It assumes user’s mechanical and cabinetry skills and familiarity with basic low voltage (dc) wiring. The Summerlift™ Marine Plasma TV lift is shipped on a shipping board. The Summerlift is connected and ready to operate. It is shipped I this fashion so that the user may become familiar with its operation.

NOTE: Plug in chargers to 110v source!
The Summerlift™ Marine Plasma TV lift uses two control boxes. The control boxes house a battery for each lift unit; relays, the remote circuit board, interconnecting wiring. The two drive units are interconnected via a coiled cord.

Both lifts have 12 feet of lifting cable installed. The cable exits from either one or both ends of each lift. The two lifts operate in the same direction.  To operate the lift in their board mounted condition, maintain a slight pull on the cables as the cable is wound or unwound.

Mounting of the lifts may be done with the lifts laying down or vertically. Note the dual locations for mounting. The drive units have mounted magic sliders as vibration isolators. These may be removed if space constraints dictate.

The Summerlift™ Marine Plasma TV lift incorporates an RF remote with a “clicker”. Extending from the control box is an antenna consisting of an approximate one-meter length of insulated wire. This wire may be fastened to the cabinetry interior in any convenient location (fasten vertically). The 9 volt-powered remote will operate from a considerable distance . In the event that more than one Summerlift is used within the operating range of the “clicker”, individual lift frequencies may be set by varying “dip” switch settings within both the “clicker” and the circuit board located inside the control unit box. Note that both clicker and printed circuit board “dip” switches MUST be identical for operation. The remote control is “alive”. It contains a conventional 9v battery. Push to operate.  

Lifting is accomplished by stainless steel cable  utilizing a series of pulleys placed to direct the lifting/lowering. The cable is attached  to and raises and lowers a platform holding television or other devices. The platform is contained within cabinetry. Two cabinetry components are:
An exterior shell and, An interior unit with the television-bearing platform at its base; two sides and back to which the outer top is fastened.

The adjusting turnbuckles (furnished) are to make final adjustments and leveling easy.

Electrical: Lift travel is constrained by magnetic limit switches (one upper and one lower). Each limit switch consists of a switch with two wires extending (mounts in a ¾” hole), and a magnet placed in line with the switches. Depending on cabinetry design, the switch portion may be affixed to either the exterior of the moving inner- unit or to the inside of the exterior shell (non-moving) shell. The magnets are positioned after the cabinetry has been assembled and the platform leveled. The magnets need to be within ½” away from, and in line with the center of the face of the switches. When the switch and the magnet are aligned, the lift stops .  NOTE: Unless both limit switches are installed and operating, the lift will continue to run in one direction until it reached the fully unwound condition at which point it will wind the cables in the OPPOSITE direction making the “up” switch the “down” switch.

Summerlift Cable Lifts operate on 12 volts, direct current. They are powered by a five-year life 12 volt battery located within the control box.  The charger is to be plugged into a 110 volt outlet. It is a “float” charger that will maintain the battery in a charged condition. The control wiring (manual/remote) carries low amperage - - so very small wire gages may be employed. The lengths of all control wires may be varied to suit installation needs. Conventional spade connectors are typically used. The manual switch should be located in a reasonably accessible position for use in the event the “clicker” is misplaced.  

SAFETY IS PARAMOUNT: Cabinetry designer/builder must consider potential hazards in raising and lowering. There should be no access to moving parts and, in the front where the top meets the exterior front, a ½” clearance ought be incorporated such that there is no possibility of fingers being caught during closing. Examine your design to be certain that there is no possibility of adults or children being able to place a finger into an area where crushing could occur.

The power lift unit 
The Summerlift Cable Lift RF remote control mounts within the cabinetry in any convenient location. The atenna consists of a one meter length of 18 gage wire that is secured to the inside of the cabinetry.

Control wiring carries less than 1/2 amp thus n
