　　Hoisting requirement

　　When engine set with package is hoisted, tight wire should be hitched at the protecting iron on the package. The engine set will always be kept steadily.

　　There are two holes specially made for hoisting on both ends of the base, from which steel tube or tight wire can be threaded through for hoisting. Necessary protection measure should be taken to keep the engine set from damage. The whole hoisting process should keep steady and slowly. Side hoisting, pulling and tilting hoisting are all strictly forbidden.

　　Installation requirement

　　1. Requirement for seat: The surface of seat to install engine set should be rather flat.

　　2. The marine engine set should be fastened with bolts on the base which is strong and horizontal. It is forbidden to weld the seat of engine set to the support in the engine room of ship.

　　3. The inner diameter of engine exhaust pipe is over 350mm, and the siphon of exhaust pipe is over 90℃. Siphons should not exceed 3. the exhaust pipes should have supports to protect silencer and turbocharger from stress.

　　4. The connecting between engine and seawater pipes should use tubes instead of rigid connection.
