50-200 EVAPORATOR FOR CHLORINE
12
EVOQUA W3T98237
WARNING: TO AVOID SEVERE PERSONAL INJURY FROM ACCIDENTAL
EXPOSURE TO HIGH VOLTAGE, THE EVAPORATOR MUST BE SUITABLY
GROUNDED TO EARTH BEFORE START-UP. USE THE GROUNDING CON-
NECTOR PROVIDED. (SEE DRAWING 50.200.130.010 FOR LOCATION OF
GROUNDING LUG INSIDE CONTROL BOX.)
CAUTION: The three-phase user power supply must be within the minimum
and maximum voltage range corresponding to the nominal voltage rating label
located just above the disconnect switch in the control box. See Table 2.1 for
this voltage range. Refer to the actual control box to verify that the nominal
voltage rating of the evaporator controls is the same as your power supply.
Table 2.1 - Power Supply Voltage Ranges
Nominal Voltage
Rating
User Voltage Supply
Minimum Maximum
208 192 218
220 194 233
240 212 254
380 336 402
440 389 466
480 424 508
550 486 582
CAUTION: If your power supply does not fall within the proper range, do
not connect power. Contact your nearest Evoqua Water Technologies re-
gional office for assistance.
NOTE: Field wiring must conform to local electrical code requirements.
2.6.1 Controls (See Dwg. 50.200.170.010)
The evaporator controls and equipment obtain 120-volt, single-phase power
from the secondary side of a transformer, located in the control box. The primary
side of this transformer is connected to two lines of the three-phase power
supply; therefore, a separate 120-volt, single-phase supply is not required from
the user to power the controls.
When the operating handle (located at the front right of the control box) for
the disconnect switch is in the off position, power is turned off to the heat
exchanger and control equipment. Line voltages for the customer-connected
alarms and the three-phase power supply are present inside the control box,
however, so observe the following warning when servicing the controls.
