SAFETY CONTROLS

Each Chiller is provided with three standard safety controls. These controls are arranged in series in the control circuit to automatically shut down the unit in the event that a condition exists which could be harmful to the re- frigeration system components. This section includes a brief description of each control, its location and some troubleshooting hints that may be helpful.

HIGH PRESSURE CONTROL (HPC)

This control prevents system operation in the event that the high side pressure exceeds 350 PSIG. If this oc- curs, check the following:

1.That the condenser is clean and that the air inlets and outlets are unobstructed.

2.That the ambient temperature at the chiller location is below 110_F.

3.That the fan blade is rotating.

Press the reset button located on the front of the control to restart the chiller. This control is located in the upper left hand corner of the electric box. If the control opens again, check the control setting with refrigeration gauges. If the setting is correct, contact technical service department.

LOW TEMPERATURE CONTROL (LTC)

This control prevents system operation in the event that the fluid inside the evaporator falls below 35_F. If this occurs, check the following:

1.That the thermostat set point is set at 40_F or greater.

2.That the flow through the system is greater than 2 gallons per minute.

This control is mounted in the lower left hand corner of the electric box. It automatically resets itself once the water temperature is restored to 38_F. The low temperature control may be adjusted for lower temperatures if a glycol solution is used. Contact Technical Service Department for temperatures below those stated here (See Fluid Recommendations page).

LOW PRESSURE CONTROL (LPC)

This control prevents system operation in the event that the low side pressure falls below 44 psi. If this occurs, check the following:

1.That the thermostat set point is set at 40_F or greater.

2.That the flow through the system is greater than 2 gallons per minute.

3.That no bubbles are present in the sight glass.

4.That water bypass valve allows flow through the Chiller in a “dead head” situation.

This control is located to the right of the high pressure control in the electric box. It automatically resets itself once the low side pressure rises to approximately 64 psi. If the control opens again, check the control setting with refrigeration gauges. If setting is correct, contact Technical Service Department.
