Chilled water system return for chilled water system supply.
B.
The factory recommends a minimum of 10 psi pressure differential
between the water supply and drain
line for proper cooling.
C.
For most applications, the drain line
should not be valved. However,
for installations with a pressurized
drain system, it may be necessary
to install a valve in the drain
line. In such cases, the installed
valve must be fully opened after
installation and the valve handle
removed to prevent operating the
unit with a closed drain valve. The
valve handle can be reattached to
the valve body when it is necessary
to close the valve (figure 2.3A).
D. CAUTION: The unit must never be operated with a closed drain line
valve. A closed drain line valve prevents adequate system cooling
and will lead to unit overheating. Overheating of the unit may lead
to unit damage and/or serious personal injury.

ELECTRICAL CONNECTION
A.
NEMA 1 MODELS
1.
Electrical power supply requirements for Nema 1 units
are identified on the equipment data tag. Verify that
available voltage supply is the same as the unit’s voltage
requirements.
WARNING: DO NOT CONNECT THE UNIT TO A
VOLTAGE SUPPLY SOURCE NOT EQUAL TO THE
UNIT’S VOLTAGE REQUIREMENTS AS SPECIFIED ON
THE UNIT’S DATA PLATE.
Use of incorrect voltage will void the unit’s warranty and
cause a significant hazard that may result in serious
personal injury and/or unit damage.
2.
For units with 10 and 16 KW heaters, a four conductor
cable, 10 foot in length, has been provided for connection to
an operator supplied fused disconnect.
3.
