OPERATING INSTRUCTIONS
OPERATOR CONTROL PANEL
AUTOMATIC (AUTO)
When AUTOMATIC is selected, the temperature comparator located within the POWER
PAK
will control
the circulation pump. This is the recommended setting for the POWER
PAK
when in normal operation.
The Power light will be ON, and the circulation pump running light will be ON when the pump is running
as determined by the temperature comparator.
OFF
When OFF is selected the circulation pump and temperature comparator will not operate. The Power
light will be OFF indicating that the control system is switched off.
MANUAL (MAN)
When MANUAL is selected the circulation pump will operate continuously. The serviceman normally
uses this selection for system testing and commissioning purposes. The Power light will be OFF and the
circulation pump running light will be ON.
CLOSED CIRCUIT FLUID LEVEL - FAULT INDICATOR
This indicator will illuminate when the closed circuit fluid level falls below 15% of the drain back tank
volume. When illuminated both circulating pumps will be prevented from operating. Illumination of the
fault light indicates a problem with the system; call a Solahart technician to examine the installation.
If the fault light comes on, the following steps must be taken:
1. the reason for the fluid loss must be determined and rectified,
2. the closed circuit refilled with the specified water and Hartgard fluid mix, and
3. the power connection reset by switching the mains OFF and then ON again.
