Water Piping

Condenser Connections

WARNING
High Pressure Water!
Failure to follow instructions below could result in
death or serious injury, and equipment damage.
Provide relief valve on system water piping to prevent
instantaneous release of high pressure water.
NOTICE
Proper Water Treatment Required!
The use of untreated or improperly treated water
could result in scaling, erosion, corrosion, algae or
slime.
Use the services of a qualified water treatment
specialist to determine what water treatment, if any, is
required. Trane assumes no responsibility for
equipment failures which result from untreated or
improperly treated water, or saline or brackish water.
Condenser water piping knockouts are in the lower left end
panel. If necessary, remove insulation to gain access. All
field-installed piping must conform to applicable local,
state, and federal codes. To complete condenser water
connections follow the procedure below.

Note: Four (4) condenser waterline drain plugs ship in a
bag in the left end of the unit. The installer must field
install these four plugs using pipe thread sealer. An
additional plug is provided for units with a waterside
economizer.
1. Install the vent plugs in the economizer coil headers
and condenser manifolds. See These plugs ship in a
bag with the condenser drain plugs.
2. Attach the water supply line to the inlet connection, and
the return line to the outlet connection. Entering and
leaving water connections for all condensers are
factory manifolded and require only single connections
for entering and leaving water. If the unit has a
waterside economizer and/or control valves, the factory
pipes between these components.
3. If using a cooling tower, refer to for a typical piping
circuit from the unit.
4. Ensure the water pressure to the unit does not exceed
400 psig.
Note: To prevent water pump damage, design system
piping to provide relief when using energy saving
waterside economizer valves.

Condensate Drain Connections

The condensate drain is internally trapped. Condensate
drain connections are on the right side of the unit. Connect
condensate drain piping to the 1-1/4" NPT internal fitting,
using at least 7/8" OD copper or 3/4" OD iron pipe. Pitch
the condensate line downward a minimum of 1/2" for each
10' of horizontal run, away from the unit. Be sure to install
