heating system
3.1.2 OIL PUMP ON/OFF SWITCH
(OPTIONAL)
•
on
– The oil pump is on . If the heating
system is active, the oil pump will circulate oil
through the heat exchanger.
•
off
– The oil pump is shut off . If the heating
system is active, coolant will be heated
normally but the oil pump will not circulate
oil through the heat exchanger and no oil
heating will occur.
3.1.3 PRIME BUTTON
Press and hold the
prime
button to energize the pump
motors in order to remove any air in the heating system
without energizing the element.
NOTICE! Do not run
the motor/pump assembly dry for more than five
seconds at a time.
NOTE: The
prime
function is intended for use during
the first run procedure ( see SECTION 3.3.1 ) or
after performing maintenance on the heating
system or plumbing ( see SECTION 4.2 ) .
3.1.4 FAULT LIGHT
The fault light will illuminate if either the motor
protection switch (MPS1) is tripped or the fluid high-limit
temperature is exceeded ( see
SECTION 4.1.1
) .
3.2 CONTROL BOX INTERNAL
COMPONENTS
3.2.1 MOTOR PROTECTION SWITCH
The motor protection switch (MPS) protects the oil pump
motor from overloads. The MPS will be set at the full load
amperage of the motor when shipped from the factory.
To reset the MPS, the heating system off/on switch must
be switched to off and the operator must press the MPS
reset button ( see Figure 7 ). See SECTION 4.1.1.
3.3 HEATING SYSTEM START-UP
WARNING
!
Hazardous voltage: Before wiring, servicing or cleaning
the heating system, turn off the power and follow your
organization’s lockout and tagout procedure. Failure to do
so could allow others to turn on the power unexpectedly,
resulting in harmful or fatal electrical shock.
NOTICE
Pump rotation (three-phase only): For three-phase
applications, check for proper oil pump rotation prior to
introducing fluid to the pump. Reverse rotation while the
pump is filled with fluid will cause pump seal failure.
Pump damage: Do not run the motor/pump assembly
dry for more than five seconds at a time. Running a
pump that is not completely filled with fluid will cause
damage to the pump seal.
3.3.1 FIRST RUN PROCEDURE
1.
For three-phase applications, ensure a motor
rotation check has been performed prior to
introducing fluid to the oil pump ( see SECTION
2.4.2 ).
NOTE: Single-phase systems are prewired to
ensure the pump motor rotates in the
correct direction. A motor rotation check is
not necessary.
