Drain hose (Figs. 6 and 7)
1. Installation of drain hose.
- The diameter of the drain hose should be
greater than, or equal to the discharge pipe
(vinyl with a 32 mm. outer diameter).
- Keep the hose at a slight 1% tilt minimum
so as to avoid internal air pockets.
- Should the hose not be inclined sufficiently,
add a slight elevation.
- To avoid detachment of the hose, locate
fasteners at at least 1-1.5 m..
- Use hose (1) and clamp (2). Insert hose
over the grey area. Screw on the clamp
until the head protrudes about 4 mm.
- Use the larger insulation to cover the drain
system.
- Insulate the drain inside the room.

2. Once installation is concluded, make sure
water flows correctly.
- Through the inspection
approximately 600 cm³ of water to the
drain system. Pour the water slowly and
check flow.
- Once wiring installation is concluded,
check drain flow in cooling mode.
