SAFETY INFORMATION 2. FIRE HAZARD Natural gas, and L.P. present a hazard of possible explosion and/or fire. This engine generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential deadly hazards; from electrical shock, exhaust gas asphyxiation, or fire. Please read all safety instructions carefully before installation or use. Keep these instructions handy for future reference.
These packaged standby systems consist of two major components: e. Always avoid hot mufflers, exhaust manifolds, and engine parts. They can cause severe burns instantly. f. Installing a generator set is not a “Do-it-yourself” project. Consult a qualified, licensed electrician or contractor. The installation must comply with all national, state, and local codes. 1. AUTOMATIC TRANSFER SWITCH A wall mounted ASCO 165 Automatic Transfer Switch (ATS) designed for inside or outside installation.
SPECIFICATIONS “Concealed Damage” is understood to mean damage to the contents of a package which is not evident at the time of delivery by the carrier, but which is discovered later. The carrier or carriers are responsible for merchandise lost or damaged in transit. The title to goods rests with the consignee when generators are shipped F.O.B. factory, and only the consignee can legally file a claim. Please note, most carriers have a time limit for filing concealed damage claims.
ENGINE GENERATOR SET MOUNTING These fuel pressures are critical; failure to provide the proper pressure can cause many problems ranging from a unit that will not start to causing damage to the fuel system. WARNING - Personal Injury The enclosures on these units can become very hot adjacent to the exhaust areas. Special care must be taken when installing these units to insure that the risk of contact by people is minimized.
FEET SIZE OF PIPE up to 25 FT* 3/4 “ Pipe 25 - 100 FT* 1” Pipe over 100 FT* Use a two regulator system. FUEL PRESSURE LP & NG VAPOR FUEL Correct fuel pressure cannot be stressed enough. The most common cause for inoperative systems is an inadequate or incorrect fuel pressure. Performance of the engine is in direct relation to the correctness of the fuel system. Shown below is a diagram of a typical LP vapor fuel installation.
LP TANK SIZING Shown below is a diagram of a natural gas (NG) installation. Required LP tank size for LP Vapor withdrawal operating at various outside temperatures given in degrees Fahrenheit (Celsius). Reference numbers 2 through 4 in the diagram above are system parts supplied by the customer. Reference number 4 is on the generator.
INSTALLING THE BATTERY WARNING - The electrolyte is a diluted sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following precautions must always be taken. **** CAUTION **** In the following battery installation procedure, check to be sure the selector switch remains in the “off” position. This should be your last step before initial start-up. * Always wear full eye protection and protective clothing.

All AC and DC connections to the ATS, 120 Volt power connection for battery charger, and battery installation are made behind this panel.
DC ELECTRICAL INTERCONNECTION The following is an optional way to interconnect the Generator and the Transfer Switch. the wires terminate on TB7 terminal as follows: **** CAUTION **** Never run the AC and DC wiring in the same conduit. ASCO 165 UL SWITCH COLOR TB7 TERMINAL #1 White #2 # 24 Red #4 # 22 Orange #7 The following leads are wire-nutted together: Your DC connection points in the ASCO 165 UL ATS are on the terminal block in the upper right hand corner of the ATS panel.
INITIAL START UP ****************** ***** WARNING ***** ****************** DO NOT jump start these generator sets. Starting these units on a low battery by jump starting them will cause damage to the engine control module. Use the following checklist to verify correct installation before starting the engine: � Engine oil. Check level & fill as required with proper grade/quantity. Refer to engine owners manual for proper levels and types. � Unit mounting base properly bolted down.
