Condensate and Water Connection
CAUTION!
CAUTION!
Ensure condensate line is pitched toward drain
1/8 inch per ft [11mm per m] of run.
Condensate Piping
Pitch the unit toward the drain as shown in Figure 5 to
improve the condensate drainage. On small units (less
than 2.5 tons/8.8 kW), insure that unit pitch does not cause
condensate leaks inside the cabinet.
Install condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection as
shown in Figure 9. Design the depth of the trap (water-
seal) based upon the amount of External Static Pressure
(ESP) capability of the blower (where 2 inches [51mm] of
ESP capability requires 2 inches [51mm] of trap depth). As a
general rule, 1-1/2 inch [38mm] trap depth is the minimum.
Each unit must be installed with its own individual trap and
connection to the condensate line (main) or riser. Provide
a means to
fl
ush or blow out the condensate line. DO NOT
install units with a common trap and/or vent.
Always vent the condensate line when dirt or air can collect
in the line or a long horizontal drain line is required. Also vent
when large units are working against higher external static
pressure than other units connected to the same condensate
main since this may cause poor drainage for all units on
the line. WHEN A VENT IS INSTALLED IN THE DRAIN
LINE, IT MUST BE LOCATED AFTER THE TRAP IN THE
DIRECTION OF THE CONDENSATE FLOW.

Figure 10: Water Connections
Water Connections-Residential (Distributor) Models
Residential models utilize swivel piping
fi
ttings for water
connections that are rated for 450 psi (3101 kPa) operating
pressure. The connections have a rubber gasket seal similar
to a garden hose gasket, which when mated to the
fl
ush
end of most 1” threaded male pipe
fi
ttings provides a leak-
free seal without the need for thread sealing tape or joint
compound. Check for burrs and ensure that the rubber seal
is in the swivel connector prior to attempting any connection
(rubber seals are shipped attached to the swivel connector).
DO NOT OVER TIGHTEN or leaks may occur.
The female locking ring is threaded onto the pipe threads
which holds the male pipe end against the rubber gasket,
and seals the joint. HAND TIGHTEN ONLY! DO NOT
OVERTIGHTEN!

* Some units include a painted drain connection.
Using a threaded pipe or similar device to clear
any excess paint accumulated inside this fitting
may ease final drain line installation.
