8.2 Condensate Drains
!
WARNING!
Do not terminate condensate drain line
– within 1 m of any outlet of engine or generator exhaust systems,
– in a compartment housing of an engine or generator,
– in a bilge, unless the drain is connected properly to a sealed
condensate or shower sump pump.
Failure to comply may allow bilge or engine room vapors to mix with the air
conditioners return-air and contaminate living areas which may result in injury
or death.
Mind the following notes on the installation of the condensate drains:
•
Do not route condensate drains to the bilge.
•
Run the condensate drain line downward from the unit to a suitable drain
location.
•
The condensate drain line should have a trap.
For installation of the condensate drain (fig. 4, page 4):
➤ Remove the aft facing watertight plug (3) from the base pan (2) of the air
conditioning unit using the hose barb (1).
➤ Screw the hose barb into the drain hole and tighten it (4).
➤ Secure the drain hose with a stainless steel hose clamp (5).
➤ Install the condensate drain hose downhill from the unit and to a safe and
proper collection point (6).
The hose should have a trap.
I
NOTE
•
Two drain fittings may be used and the hoses teed together provided there
is a minimum 50 mm drop from the bottom of the base pan to the tee
connection.
•
Consideration should be given to installing a trap in the condensate drain
line(s) so that normal discharge of condensate can fill the trap and prevent
the ingress of carbon monoxide (CO) or other potentially harmful vapors.
➤ Test the installation by pouring one liter of water into the base pan and check-
ing for good flow.
