Vertical Discharge Condensate Installation
Note
A trap must be fitted between the condensate drain of the unit and the rest of the waste system.
A waterless trap is recommended, as they are not susceptible to drying out during warmer periods
when no condensate is formed. An example of a suitable waterless trap is the Osma HepVo
waterless trap.
If a conventional trap is used, a trap with a minimum water seal of 60mm must be selected.
The condensate outlet is compatible with standard 22 mm plastic solvent weld fittings and 32mm threaded
waste pipe fittings. Wastepipes must have a 3 degree minimum angle to allow the water to drain away from
the unit naturally.
In areas where freezing weather conditions occur, outlet pipes must be insulated to avoid blockage by ice,
which may cause damage to the unit and surroundings.
This guide shows a Right Hand configuration for illustration.
If the unit is configured as Left Hand, then the condensate drain should be installed on the left with
the blanking cap on the right.
22mm waste pipe
Fit a waterless trap, or a conventional trap
with a water seal of at least 60mm, close
to the unit.
An adaptor can be used to adapt from
32mm to 22mm connections.
Fit the blanking cap supplied with the unit
to the appropriate side, depending on the
handing, see page 4. Ensure the sealing
gasket is fitted inside the blanking cap.
32mm waste pipe (recommended)
Fit a waterless trap, or a conventional trap
with a water seal of at least 60mm, close to
the unit.
Fit the blanking cap supplied with the unit
to the appropriate side of the unit,
depending on the handing of the unit, see
page 4. Ensure the sealing gasket is fitted
inside the blanking cap.
