3.7. Drainage Connection
In drainage piping, it should be regarded that pipe diameter to be smaller than condensation pan outlet
diameter.
Connection between drainage pipe and condensation pan should be made with union flange so that dirt
occurred in the condensation pan and pipes could easily be cleaned.
Drainage pipe coming out from the condensation pipe should be connected according to the figures below
by using flusher provided with the device.
If drainage piping is long, a declination smaller than 1/50’ should be given to the drainage line.
More than one flush shouldn’t be connected to the same pipe. For these cases, instead of using pipes,
using of ducts open to the atmosphere and separate connections from the flush to this ducts are
recommended.

H1 refers to the total base elevation (consisting of concrete mount basement made by customer and metal
base produced by Üntes).
H1 = P + 75 ( mm)
(“P” value within the formula is the static pressure value within cell in which there is ceiling and ÜNTES
is responsible for that.)
