HOW TO USE A HIGH PERFORMANCE BLOWER MOTOR

Written by HydroHoist Marketing

The high-performance two-valve, two-motor control unit is typically installed on hoists up to 14,000 pounds, with two tanks, that are set up for boats that are backed into the slip. It can also be used for a two-tank hoist that is modified to accommodate a sailboat. The high-performance blower motors can push the air to a deeper water depth than the standard blower motors.

To raise the boat, position the boat directly over the hoist using the guide ropes, switch on the blower motors by flipping the black switch to the power-on position, and simultaneously turn the two levers to the Lift/Launch position. Once the boat is fully raised and bubbles are exhausted from the tanks, turn the levers to the Dry Dock position and switch off the blower motors.

To launch the boat, simply turn the levers to the Lift/Launch position. Remember, do NOT switch on the blower motors when launching the boat.

*Normally, you will open and close both levers at the same time. However, with this control, you can manipulate the valve position to control the airflow to the port and starboard air tanks. In a back-in application the ability to control airflow, port and starboard is important. Because of the longer stabilizer arms and the increased travel, any imbalance in the boat is greatly exaggerated during the lift/launch process. By manipulating the airflow, you can counteract the imbalance if necessary. You can pause the lift/launch process at any time by turning the levers to the dry dock position and switching off the blower motors.
