Simrad SP270 Equipment handling Introduction This chapter describes how to transport, pack and unpack, clean, preserve and store electronic, electro-mechanical and mechanical units supplied by Simrad AS. The units may be supplied as spare parts, or as parts of a delivery.
Introduction Lifting A heavy crate will normally be marked with its weight, and the weights of other cartons or crates will normally be entered on the packing list. • Always check the weight of a crate before attempting to lift it. • Always use lifting apparatus that is certified for the load. Heavy units may be equipped with lifting lugs for transportation by crane within the workshop or installation area. Before a crane is used, check: • The applicable weight certificate for the crane.
Simrad SP270 4 The crates must not be placed on top of each other, unless specific markings permit this. 5 The crates must not be placed directly on a dirt floor. 6 Do not open the crate for inspection unless special circumstances permit so. - “Special circumstances” may be suspected damage to the crate and its content, or inspections by civil authorities. - If any units are damaged, prepare an inspection report stating the condition of the unit and actions taken.
Introduction Batteries If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must only be reconnected before the installation starts. Units containing batteries are marked. Caution Units containing lithium or alkaline batteries must be handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.
Simrad SP270 • Place the carton on a stable work bench or on the floor with the top of the carton uppermost. • In the absence of other instructions, always open the top of the carton first. The contents will normally have been lowered into the carton from above, so this will usually be the easiest route to follow. - Care must be used when opening the carton to ensure the contents are not damaged.
Introduction Mechanical units Mechanical units may be heavy. Using a suitably certified lifting apparatus, lift the unit out of the crate and place it in a stable position on the floor/work bench. Inspect the unit for damage and remove any packing material that may be inside the unit. Transducers Transducers may be supplied mounted to a hull unit (if any), or packed separately. Crates are normally identified by the order number and the serial number.
Simrad SP270 If the unit contains normal batteries, these may have been disconnected/isolated before the unit was packed. These must then be reconnected during the installation procedure. Units containing batteries are marked. Caution Units containing lithium or alkaline batteries must be handled separately and with care. Such units are marked accordingly. Do not attempt to recharge such batteries, open them or dispose of them by incineration. Refer to the applicable product data sheets.
Introduction • Ensure that all traces of mud and marine growth are removed. Use a wooden or plastic scraper to remove persistent growth, barnacles etc. On completion, dry the unit thoroughly. Caution Do not use a high pressure hose in the vicinity of cables or transducers. Do not use sharp or metal tools on a transducer face. • If the materials or type of unit prevents the use of a high-pressure hose, wipe the unit using a cloth dampened with water containing a little detergent.
Simrad SP270 Dehumidifier Place a suitably sized bag of desiccant material (silica gel or similar) into the unit to keep the electronic components as dry as possible. Coatings Spray the unit externally with a corrosion inhibitor (e.g. a light oil) before packing. Re-packing The unit should be stored and transported in its original packing material and/or crate.
Introduction Unpacking and servicing ESD sensitive equipment If it is necessary to open and touch the electronics inside the boxes/cabinets, then the following precautions MUST be taken: • The working area must be covered by an approved conductive service mat that has a resistance of between 50kΩ and 2 MΩ, and is connected directly to a reliable earth point via its earthing cord. • The service personnel involved must wear a wrist-band in direct contact with the skin, connected to the service mat.
