Installation and maintenance

For professional installation, technicians should inspect the timing belt and drive belts during replacement. It is recommended to check the mechanical seal and impeller integrity during service to prevent leaks or bearing play. Ensuring proper mounting and using high-strength components helps extend the service life of the entire cooling circuit.
