3. Attach the filter brackets to the waterside
economizer using five screws. Install the air filter.

Step 3
4. Install the braided hose connecting point A (leaving
the WSE) to point B (entering the WSHP). Connect
the supply water to point D and the return water to
point C.

Step 4
5. Locate the entering water sensor that is located
behind the unit’s control box, and wire tie it to the
water SUPPLY side of the piping. The sensor must
be mounted before the two-position valve.
Attaching the sensor anywhere else will cause the
WSE to not operate correctly. Bundle up any excess
sensor wire and wire tie the bundle neatly.
6. Locate the WSE valve wires (35B (COM), 36B
(OPEN), 37B (CLOSE)) behind control box, and
connect to the valve actuator. Bundle up any excess
wire and wire tie the bundle neatly. Direction of
rotation is reversible with switch.
7. Insulate the economizing piping package and the
associated hoses via field pipe insulation Insulating
the piping will prevent condensation from forming
on the pipe and dripping on the floor.

ess::
•
Trane does not provide insulation on the
economizing piping package. This insulation
must be field provided and field installed.
•
Trane does not provide condensate
overflow protection of the waterside
economizer. This must be field provided and
installed.
8. Field pipe the drain lines of the waterside
economizer and water-source heat pump together
prior to installing a condensate trap for proper
trapping of condensation (see
). The
vertical units will be piped similar to the horizontal
units.
