e.
Insulate the connection points on the interior section with insulation material to prevent condensa-
tion build-up .

ATTENTION
Always use the highest care when bending the piping. Make sure that the piping always is
bent and not buckled. In case of a buckled pipe: replace the complete piping or the buckled part,
as this is a potential refrigerant leak and may cause damage to the air conditioner.
9. CONNECTION THE CONDENSATION DRAINAGE HOSE FOR THE S42XX &
S52XX(B) & SJA2519, SC42XX, SC52XX MODELS
9.1 Connection the condensation discharge hose to the interior unit.
Connect the included condensation drainage hose to the interior unit by sliding the hose over the hose nip-
ple on the interior unit. Ensure that the condensation drainage hose always runs downwards and do not
hang the end in the water. See fig. 15.
Always run the condensation drainage hose under the coolant pipes to prevent that the condensation tray
from overflowing.
CAUTION
• Be sure that the drain hose is located at the lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the unit.
• Run the drain hose sloped downward over the whole length to drain out the condensed water
smoothly.
