WSHP-SVX13C-EN
Before installing any wire, refer to the electrical access
locations in
“Unit Dimensions,” p. 9
of this manual.
Ensure that the AC control wiring between the controls
and the unit’s termination point does not exceed three (3)
ohms/conductor for the length of the run.
Note:
Resistance in excess of 3
Ω
per conductor may
cause component failure due to insufficient AC
voltage supply.
Check all loads and conductors for grounds, shorts, and
mis-wiring.
Use copper conductors unless otherwise specified.
Do not run the AC low voltage wiring in the same conduit
with the high voltage power wiring.
The field supplied line voltage disconnect (1) should be
installed for branch circuit protection.
Check local codes for requirements.
•
The units (2) ¾-inch high voltage and (3) ½-inch low
voltage connections are located on the left corner of
the unit.They are designed to accept conduit.
•
Trane recommends that the condensate system (4) be
set-up per negative pressure trapping in consideration
of the unit's draw-through design. With this properly
trapped system, when condensate forms during
normal operation, the water level in the trap rises until
there is a constant outflow.
•
For acoustically sensitive areas, a ½-inch thick field
provided vibration pad (5) should be installed below
the vertical unit.This field provided piece should be
equal to the overall footprint size of the unit to provide
sound damping of the unit while in operation.
•
Hose kits (6) are used to connect the water supply and
return lines to the water inlet and outlets. Trane
includes various hose kit combinations to better
facilitate system flow balancing.These flexible hoses,
reduce vibration between the unit and the rigid piping
system.
