2.3.3 Installing the Main Body Unit
[Fix the hoisting stand firmly]
Water level
(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 secure the condensate 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 remaining nut.
(6) Remove the paper template.
2.3.4 Installing the Suspension Bolts
(1) Using the installation template, drill holes for bolts (four holes) (Figure 3-1-40).
(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 12.7mm (1/2inch) diameter holes
(Figure 3-1-41).
(3) Insert the anchor bolts into the drilled holes, and drive the pins completely into the anchor bolts
with a hammer (Figure 3-1-42).
