3-1 Set up of the Drain Pump

● Remove the cover and the mounting plate which is fixed on the back of the Drain Pump each.

* The packaging material which is put between the cover and the main body of Drain Pump is only for cushion for

transportation. Take it out as it is unnecessary.

* Take out the accessories.

● Run the pull tight (F) attached through the square hole on the mounting plate.

● Cut the knock out hole on the cover with a nipper and etc.

● The installation place should be carefully considered if 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 pattern (G) attached.

(* The left end of the indoor unit should be marked in advance.)

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

pattern.

(2) Fix the mounting plate with the screws (B) (M4 × 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 M10 or W3/8 screws locally

and put them into two ø 12 holes of the mounting plate to fix it.

(3) When the mounting plates is installed, remove the paper pattern.

(4) Check that the mounting plate is level and positioned correctly

with the indoor unit. (Fig. 2)
