♣ Mounting instruction:
♣ Temperature parameter
Medium liquid temperature: -40℃ to +120℃ (-40°F to + 248°F)
Working ambient temperature: -40℃ to +100℃ (-40°F to +212°F)
Storage temperature: -40℃ to +70℃ (-40°F to +158°F)
(up to 100 ℃, but it will shorten the service life)
♣ System pressure
-0.2 to 2.5 bar ( 100℃ (212°F).
The service life is more than 20,000 hours based on the rated voltage and 36℃(86°F) ambient temperature.
♣ Connector model and Pins
♣ Attentions
1. Working ambient temperature:-40℃--120℃, should try to avoid close to three-element catalytic, gas discharge pipe system and engine during the installation, ensure the working environment temperature.
2. The installation position of the water pump should as much as possible close to the low water level, to extend the service life of the pump.
3. In order to reduce water resistance, should as much as possible to reduce the number elbow in piping in the installation, ensure no any elbow within 20 cm from the pump.
4. Please use the pump far from the dusty environment, the dust is harmful to reduce the service life
5. Pay attention to the purity of the water, avoid to jam and impeller-blocked to reduce the service life of pump.
