M-SQ PRO 15/18 kVA 60 Hz Marine Diesel Generator M-SQ Pro 15 and M-SQ Pro 18 2.3.1 Features This generating set includes a 4 cylinder diesel engine which is connected by close coupling to a one or tree phase synchronous alternator in a sound attenuated capsule. The set is mounted on a steel base frame and mounted securely on anti-vibration mounting pads to the capsule base. The complete set is again on rubber mountings. All cables and hoses are guided through the capsule’s sides. The set is not self-contained and is only operable after proper installation using additional accessories and installa- tion materials. Installation accessories are listed in the installation manual and are available through the supplier of the generating set. The full automatic Digital Control is based on microprocessor technology. Several automatic start/stop functions can be programmed and monitored (see Digital Diesel Control user manual). 2.3.2 Remote control The full automatic remote control panel including 15 mtr cable comes as standard with the Whisper generating M-SQ Pro 15 / 18. 2.3.3 Documentation Included in the delivery are: •... -

Page 13: Cooling Liquid
M-SQ PRO 15/18 kVA 60 Hz Marine Diesel Generator 2.5.13 Cooling liquid The engine is cooled by cooling liquid. The capacity is: 4,0 ltr. for SQ Pro 15 / 8,1 ltr. for SQ Pro 18 A lways use coolant which is compatible with alumini- um components of the cooling system. Do not mix coolants with different kinds of chemical compound, as this may cause the refrigerant to freeze. In case of doubt refresh the content of the entire cooling system. Use only long-life type G12+ cooling liquid in order to minimize maintenance. We recommend not using water but cooling liquid that is market- ed for the use in combustion engines. Cooling liquid protects the engine against frost to minus 25° C. Also it protects the engine block against corrosion. One can fill the engine via the filling cap on the exhaust manifold. Fill up till the fluid is leveled with the indicator in the manifold (see fig 7 ). When the engine is on temperature the liquid will expand and the redundant liquid will be pressed into the expansion tank. This tank has to be filled up till the mark. When cooling liquid is not available clean fresh water could be used with an additive of anti-freeze. When using water with anti- freeze the right mixture has to be calculated according to the information of the supplier of the anti-freeze. When the cooling is based on keel cooling or radiator cooling the capacity of these coolers and piping has to be taken into account calculating the right mixture. The cooling liquid in the engine is pressurized and has a boiling point above 100° C. The temperature switch in the thermostat housing switches at 110° C. When keel cooling is applied the cooling system is not pressurized. There should be a special cap... -
