WARNING: LINE VOLTAGE IS PRESENT INSIDE THE CONTROL BOX
EVEN WHEN THE PANEL POWER SWITCH IS IN THE OFF POSITION.
TO AVOID POSSIBLE SEVERE PERSONAL INJURY DUE TO ELECTRICAL
SHOCK, DISCONNECT EXTERNAL POWER SUPPLY BEFORE SERVICING.
2.6.2 Heat Exchanger
The heat exchanger nameplate voltage must be within the user voltage supply
range corresponding to the nominal voltage labeled inside the control box above
the disconnect switch. See Table 2.1. If this is not the case, the heater must
be exchanged for one of the proper value. If necessary, contact your nearest
Evoqua Water Technologies regional office for assistance.
NOTE: For 220 Nominal Voltage Users: If the heat exchanger nameplate volt-
age rating reads as either 220/240 VOLTS or 240 VOLTS, do not return the
heater. This is the proper heater for this evaporator arrangement.
For 440 Nominal Voltage Users: If the heat exchanger nameplate voltage
rating reads as either 440/480 VOLTS or 480 VOLTS, do not return the heat
exchanger. This is the proper heat exchanger for this arrangement.
2.6.3 Hot Water Circulating Pump
A circulating pump is provided and runs continuously while the evaporator is
working. The controls are designed to shut the pump off in the event of a low
water level condition.
The fractional hp 50/60 Hz motor that drives the pump is a totally enclosed
type, suitable for outdoor use.
2.6.4 Evaporator Gas and Liquid Line Pressure Relief Systems
Wire the pressure switch of each system directly to an alarm device or relay coil
per Dwg. 50.200.130.020. The pressure switches are preset to activate at 20psi.
Every relief system, either liquid line or gas pressure relief, is supplied with
the appropriate rupture disc, which is to be installed after all initial pressure
testing is completed. (See paragraph 3.1, Preparation For Initial Operation.)
