Five and Six Valve Control General Operation
Familiarize yourself with the Control Box. We have created a simple to use 4 BUTTON user interface con-
sisting of UP, STOP, DOWN, and AUX buttons. These are the basic functions for operating the Har-
borHoist
lift. The state-of-the-art valve controls and circuitry will insure that your lift comes up level each
and every time you lift your boat from the water.
Lowering the lift:
Make sure the Power LED is illuminated and flashing
Press the
DOWN
button, this will open the valves
Allow the lift to submerge (walkways will remain above water)
Untie lift safety lines from boat
Board the boat after the boat clears the lift
Raising the lift:
Make sure the Power LED is illuminated and flashing
Float boat into established balanced lifting position on the lift
Tie off safety lines to the boat
Everyone must exit the boat before lifting
Press
UP
button
Once the lift is fully raised, air bubbles will be visible exiting from ALL main tanks
Press STOP on control
AUX lift:
The Aux feature will allow you to utilize the full lifting capacity of a lift system with auxiliary tanks. By
pushing the AUX button it will close the main tank air valves and direct all air to the auxiliary tanks allow-
ing them to be emptied completely of water, giving you the maximum lifting capacity of the system.
The
AUX
button should only be utilized when the lift has reached full lifting capaci-
ty on the main tanks
.
Verify all the main tanks have bubbled out
Press the
AUX
button on the controller
When the auxiliary tanks have bubbled out press the
STOP
button
