Low#Limit Open50 Close95 Open50 Close95_Automatic Reset High pressure limit and automatic reset in case of high pressure loss at the discharge cylinder (pressure lower than 6 bar) The RHEEM 47-101529-09 low pressure limit - auto reset This thermostat is a float-operated, spring-wound, temperature sensitive device that protects the RHEEM 47-101529-09 heater from either freezing or overheating The low pressure limit - auto reset's temperature rating is 100°F Low RHEEM's Low Pressure Limit - Auto Reset monitors your system and automatically resets to zero when low water pressure is restored It features a six foot cord that attaches to any standard 3/4" copper supply line, along with an adjustment collar for setting the water pressure __ The Rheem Low Pressure Limit - Auto Reset keeps your system from getting clogged up if the refrigerant pressure drops too low by shutting off the fan It then turns itself back on when the pressure climbs back above 95 psi The Rheem Low Pressure Limit Regulator provides constant pressure and flow control The Low Pressure Safety device will only allow a 50 psi gas supply to be connected to the regulator until it senses an increase in system pressure to 95 psi At this point it resets itself and will allow pressures to go to 200 psi without any further need for human intervention
