4. Installation of the Drain Pump
4-1 Fixing of the mounting plate
• The installation place should be carefully considered about whether
it is proper for installation. If it is not strong enough to hole the unit,
make it stronger by using board or beam before installation.
(1) Decide the installation position of the mounting plate by using the
paper gauge (G).
(* The left end of the indoor unit should be marked in advance.)
1) Fix the paper gauge (G) on the wall with the screw (C) (4 x 16)
attached with putting it to the left end of the indoor unit for
positioning of the Drain Pump as shown in the drawing.
2) Position the mounting plate with pushing it against the paper
gauge (G).
(2) Fix the mounting plate with the screws (B) (4 x 35) attached.
Fix the mounting plate using the 5 dia. holes.
(6 locations pointed by arrows in the drawing.)
In case that the mounting plate is fixed by fixing bolts (through
bolts, bolt anchors, or nut anchors), get M 10 or W3/8 screws locally
and put them into two 0 12 holes of the mounting plate to fix it.
(3) When the mounting plates is installed, remove the paper gauge (G).
(4) Check that the mounting plate is level and positioned correctly
with the indoor unit as shown in Fig.2.
