5.5kw to60KW Swimming Pool Heat Pump / Electric Water Heater — Digital Display Swimming Pool and SPA Thermostat, Precision 1_HL-300

Warning: if the water pump is not properly matched to the thermostat, insufficient flow can occur and the heating tube may be damaged by dry burning. For units with power below 11KW, the supporting water pump must be at least 750W and provide a flow of no less than 13 cubic meters per hour. For units with power above 11KW, the supporting water pump must be at least 1.1KW and supply a flow of no less than 18 cubic meters per hour. Startup/shutdown procedure: always start the water pump first, then switch on the thermostat; when turning off, switch off the thermostat and wait 10 seconds to 1 minute before stopping the pump. Note: approximately 1KW of thermostat heating will heat about 1 cubic meter of water; outdoor swimming pools will require additional heating power.
