Titan Central Chillers
3. After electrical installation the rotation must be checked by observing the pump
motor shaft on the end of the pump and comparing its rotation to the directional
arrow on the motor.
4.
If the rotation needs to be changed it should be done at the main power entry by
switching any two power conductors at the terminal block or customer supplied
main power disconnect. Recheck rotation before operating the units.
5.
Caution must be taken when checking rotation to avoid electrical shock.
6. A scroll compressor may make a loud rattling noise when rotating in the wrong
direction.
7.
Operating the scroll compressor in the wrong direction will cause the unit to
trip on it's internal temperature limit and may cause unit damage. When the
temperature limit trips, the compressor must be allowed to cool before it will
restart. This many take substantial time.
8.
Procedure to set proper rotation:
a.
b.
c.
d.
e.
Supply electrical power to the unit. Once the correct voltage is supplied
to the unit, the POWER switch on the unit's control panel will illuminate.
Adjust the setpoint to 70°F or higher to prevent the compressor from
activating during this procedure.
Remove all necessary cover panels to access the pump motor.
Locate the pump's electric motor. The operator must identify the motor
shaft inside the electric motor housing. The motor shaft can be seen
through the vent slots in the motor housing or by removing the shaft
cover.
Pump Control Switch
Toggle the Pump ON/OFF switch. This
will quickly cycle the pump motor "on" and
then "off".
Observe the motor shaft. When the ON/
OFF SWITCH is on, the motor shaft
will rotate. When switched off, the shaft
will slowly "coast" to a stop. As the
shaft slows, the operator can identify
the rotation of the motor shaft. Correct
rotation (correct phase) is "clockwise",
when viewed from the rear of the motor.
