Acnodes Q5RF SERIES ¢709158D¤, COMPONENT FUNCTIONS Low Pressure Switch, High Pressure Switch

COMPONENT FUNCTIONS

Low Pressure Switch

The low pressure switch is factory installed and located in the suction line internal to the unit.The switch is designed to protect the compressor if a loss of charge occurs. Under normal conditions, the switch is closed.

If the suction pressure falls below 5 psig, then the switch will open and de-energize the unit.The switch will close again once the suction pressure increases above 20 psig. The low pressure switch interrupts the thermostat inputs to the unit. NOTE: When the switch opens and then closes, there will be a 5 minute short cycling delay before the unit can energize.

High Pressure Switch

The high pressure switch is factory installed and located in the compressor discharge line internal to the unit.The switch is designed to de- energize the system when very high pressures occur during abnormal conditions.Under normal conditions, the switch is closed.

If the discharge pressure rises above 650 psig, the switch will open and de-energize the unit. The switch will close again once the discharge pressure decreases to 460 psig. The high pressure switch interrupts the thermostat inputs to the unit. NOTE: When the switch opens and then closes, there will be a 5 minute short cycling delay before the unit can energize.
