Install the external heat exchanger
An external heat exchanger is an option for air-cooled pumps.
1. Use the attached mounting bars to secure the heat exchanger to the ground or on an elevated platform.
2. The heat exchanger includes 2 hydraulic hoses that are approximately 9 m (30 feet) long. Connect 1 end of each
hose to the top and bottom ports on the heat exchanger.
3. Connect the 4-conductor cable from the external heat exchanger motor to the panel in the electrical enclosure.
 The full load amperes, overload settings, and wire sizes are different, depending on the motor size.
 For more information, refer to the electrical enclosure schematic.
Push the cable through the cord grip connector in the electrical enclosure. Connect the cable to the motor
starter–contactor.
Make the connections for remote operation

Remote operation is optional.

All controls are 24-volt direct current (DC).
These tables describe the remote connections from a user panel or a computer numerical control (CNC) operator
console.
Emergency stop
The OEM or the system integrator is responsible for connecting the emergency stop.
The terminals are in series with the emergency stop circuit. The terminals are wired to dry contacts on the emergency
stop at the remote control source.
If the pump is configured to run remotely and has a motion system (robot or cutting table), the emergency circuits from
the robot or cutting table can be in series with the local emergency stop circuit.
Make sure that there is a minimum clearance of 91 cm (36 inches) in the front and rear of the heat exchanger
to permit enough air flow for efficient cooling.
