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.
N No otte e:: 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.
N No otte e:: To prevent water pump damage, design system
piping to provide relief when using energy
saving waterside economizer valves.

cleanout/drain plugs.
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
female fitting, using at least 7/8" OD copper or 3/4" OD
iron pipe. Pitch the condensate line downward a
