Countermeasures in the event of refrigerant leaks
The room should have the following characteristics in case of a
leak of refrigerant:
1
Opening without shutter to permit the circulation of fresh air
in the room.
2
Opening without door measuring 0.15%, or greater, of the
floor surface.
3
A fan with a capacity of at least 0.4 m
3
/minute per tonne of
Japanese refrigerant ( = volume displaced by the compressor
/ 5.7 m
3
/h) or greater, connected to a gas sensor in the air
conditioning system which uses the refrigerant.
D A N G E R
Special attention should be given to areas where the refrige-
rant may be deposited and stay in the room, such as base-
ments or similar, as it is heavier than air.
9.5.2 Drainage pipes
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.
D A N G E R
• Drainage must not take place in areas frequented by pe-
destrians. 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 clima
-
tes, as they could freeze and break.
If a condensation drainage kit is required for the outdoor unit, use
the optional drainage kit DBS-TP10A.
