(1).
Install the hoisting stand on the hoisting screw by using nuts and gaskets at both
the upper and lower sides of the hoisting stand. To prevent the gasket from
breaking off, a gasket anchor board can be helpful.
(2).
Install the paper template on the unit, and fix the drain pipe at the outlet vent.
(3).
Adjust the unit to the best position.
(4).
Check if the unit is installed horizontally at four directions. If not, the water pump
and the float switch would function improperly and even lead to water leakage.
(5).
Remove the gasket anchor board and tighten the nut remained.
(6).
Remove the paper template.
4.1.3 Installing the Suspension Bolts
(1).
Using the installation template, drill holes for bolts (four holes). (Fig. 4.4)
(2).
Install the bolts to the ceiling at a place strong enough to hang the unit. Mark the
bolt positions from the installation template. With a concrete drill, drill for 12.7 mm
(1/2”) diameter holes. (Fig. 4.5)
(3).
Insert the anchor bolts into the drilled holes, and drive the pins completely into the
anchor bolts with a hammer. (Fig. 4.6)
