▪ Install the unit temporarily.
12 Attach the hanger bracket to the suspension bolt.
13 Fix the unit securely.
14 Adjust the unit to fit between the walls.
▪ Level. Make sure the unit is level at all four corners using a level
or a water-filled vinyl tube.
15 Tighten the upper nut.
NOTICE
Do NOT install the unit tilted. Possible consequence: If
the unit is tilted against the direction of the condensate flow
(the drain piping side is raised), the float switch might
malfunction and cause water to drip.
▪ Fixing the unit. Level the unit with the levelling screws
(accessory). If the floor is too uneven to level the unit, place the
unit on a flat and levelled base. If the unit is in danger of falling
over, fasten it to the wall using factory-made holes or to the floor
using floor fasteners (field supply).
