Connection procedure of ATH 500 MT pump model
1. Provide a water-cooling circuit.
2. Connect the cooling circuit to the connectors provided while respecting the flow direction:
– WATER IN = water inlet on the solenoid valve
– WATER OUT = drainage circuit.
3. Check that there are no leaks in the water circuit or the water circuit connections.
5.5 Installation of the air cooling accessory
An air cooling accessory can be ordered separately (see chapter "Accessories"). The customer is re-
sponsible for installation.
Depending on ordering configuration (air cooled version), the pump is equipped with a fan as a factory
setting. In this case, only the electrical wiring is the customer’s responsibility.
With the air cooling, the maximum admissible gas flow is decreased!
User will have to check the maximum inlet flow and reduce the ambiant temperature to
avoid any overheating of the pump.
In continuous use, the current consumption must be less than 3.8 A: this parameter can be
monitored via the control interface.
