Hydraulic Installation
All red light diagnostic functions will shut down the sys-
tem and require the operator to remedy the problem
before it can be restarted.
Pump Overload Indicator
The Pump Overload Indicator will illuminate when the
pump draws too much current. Low line voltage, single
phase power input, and a seized pump motor are all
possible causes for pump overload.
ELECTRIC SHOCK HAZARD. If the Pump Over-
load Indicator is illuminated, disconnect all
power and piping to the system. Failure to do
so could result in personal injury or equipment
damage.
After the system power is disconnected, solve the
electrical current problem. To put the pump back on-
line, open the front electrical enclosure and press the
pump reset switch. See Figure 5.2.
Figure 5.2 Pump Reset Switch
ELECTRIC SHOCK HAZARD. Close the front
electrical enclosure door and retighten the
locking screw. This must be done to limit ac-
cess to high voltage components. Failure to
comply could result in personal injury or equip-
ment damage.
Over-Temperature Controller
If the system temperature exceeds 600°F (315°C), the
Over Temperature Indicator will illuminate. When the
system temperature drops below 550°F, press reset on
the over temperature controller inside the panel. Close
door and retighten the screw. The controller will not
reset until the temperature is below 600°F. Or remove
electricity to the product and the over temperature
controller will reset after temperature is below 600°F.
