DRAIN PIPING

9 DRAIN PIPING
9.1 CONDENSATION DRAINAGE SYSTEM
When the outdoor unit operates in refrigeration or heating mode,
there is a build-up of condensation of the ambient humidity
which, together with rain water, requires draining.
Select a location for the unit which permits adequate drainage.
If necessary, mount an installation suitable for the drainage of
condensation.

• Drainage must not take place in areas frequented by pedestrians.
In low temperatures, the drainage water could freeze and lead
to falls. If it is necessary to install the outdoor unit in an area
frequented by pedestrians, an additional drainage tray should
be fitted.
• Do not fit drainage pipes or collection trays in cold climates, as
they could freeze and break.
If a condensation drainage kit is required for the outdoor unit,
use the optional drainage kit DBS-TP10A.

C A U T I O N
• Before any work to the electrical wiring or regular inspections, switch
off the mains power supply of the indoor and outdoor units. Wait three
minutes before starting installation or maintenance work.
• Make sure that the interior and exterior fans have come to a complete
standstill before starting work on the electrical wiring or regular
inspections.
• Protect cables, the drainage pipe, electrical components, etc. from
rodents and insects; otherwise these might damage unprotected
components and this could result in fire.
• Do not allow cables to come into contact with the refrigerant pipes,
metal edges, printed circuit boards (PCB) or the electric components
inside the unit; the cables may be damaged and this could result in
fire.
• Firmly secure the cables inside the indoor unit with plastic flanges.

activation speed of 0.1 or less. If this is not fitted, there is a risk
of electric shock and/or fire.
• Install an earth leakage breaker, fuse and circuit breaker for
each outdoor unit power line. Not fitting it may cause an electric
shock or fire.
