TP-5700 7/93 3 Section 2 Load and Transport Section 2 Load a nd T ransport T o ensure personal safety while preventing damage to the product, we strongly recommend the following guidelines be observed when loading and transporting standby generator sets.
TP-5700 7/93 4 Section 2 Load and Transport D A four-point lifting method is necessary to lift the generator set. T o maintain generator balance during lifting, the lifting apparatus must utilize the four skid lifting holes mentioned in the previous paragraph.
TP-5700 7/93 5 Section 2 Load and Transport D Do not attach lifting hooks to outside reinforcing plate on skid. Attach lifting hooks to skid exactly as shown in Figure 2-4. This method utilizes the strongest portion of the mounting skid and also prevents the lifting hooks from slipping.
TP-5700 7/93 6 Section 2 Load and Transport Notes.
TP-5700 7/93 7 Section 3 Location Section 3 Location 3.1 Location Factors Location is the key to a proper installation. The following sections will deal with the factors to consider in a proper installation. Before final plans are made for locating a generator set, the following questions should be raised concerning the set and the proposed site.
TP-5700 7/93 8 Section 3 Location 3.3 Mounting T ypical mounting surface details and dimensions are shown in Figure 3-1. The recommended mounting surface is a concrete mounting pad. This must be a level surface as shown in Figure 3-2, or raised pads as shown in Figure 3-3 and Figure 3-4.
TP-5700 7/93 9 Section 3 Location The composition of the mounting pad should follow standard practice for the required loading. Common specifications call for 2500-3000 psi (176-21 1 kg/cm 2 ) concrete reinforced with eight-gauge wire mesh or number 6 reinforcing bars on 12-inch (30-cm) centers.
TP-5700 7/93 10 Section 3 Location Notes.
TP-5700 7/93 11 Section 4 Air Requirements Section 4 Air Requirements 4.1 General An ample flow of clean, cool air is required to support combustion and dissipate heat. Approximately 70% of the heat value of fuel consumed by an engine will be rejected to the cooling system and exhaust.
TP-5700 7/93 12 Section 4 Air Requirements In many installations it may be desirable to install louvers in the inlet and outlet openings. Louvers may be either stationary or movable. In areas of great temperature variation, it is often best to install movable louvers that can be thermostatically adjusted to regulate air flow and room temperature.
TP-5700 7/93 13 Section 4 Air Requirements 4.3 Forced Air With the forced-air system, cooling air is drawn in through the front of the engine, circulated around finned areas of the cylinder block and head, then ejected toward the rear or generator end of the set.
TP-5700 7/93 14 Section 4 Air Requirements 4.4 Air - V ac Cooling System The air flow direction with the Air-V ac system is the opposite of the conventional forced air cooling system. Use the Air-V ac system in confined areas since it includes a blower scroll which easily connects to the ductwork.
TP-5700 7/93 15 Section 4 Air Requirements 4.5 Air V ent The air vent system is used on some air-cooled gas and has been used on some diesel models. It includes special ductwork which directs the flow of heated air to the outlet at the top or side of t he engine.
TP-5700 7/93 16 Section 4 Air Requirements 4.6 Liquid -Cooled Models The three most common liquid cooling systems used for generator sets are unit-mounted radiator , city water , and remote radiator cooling. Since each involves somewhat different installation considerations, they will be discussed separately .
TP-5700 7/93 17 Section 4 Air Requirements The connection from the radiator duct flange to the ductwork should be heavy canvas, silicone or similar flexible material to prevent noise and vibration transmission. Sheet metal ductwork should be self-supporting.
TP-5700 7/93 18 Section 4 Air Requirements The engine water pump can be used to circulate water through the remote radiator providing that the vertical distance from the engine water pump does not exceed the engine manufacturer ’s recommendations. The allowable static head may range from 17-50 feet (5.

TP-5700 7/93 20 Section 4 Air Requirements 4.1 1 Block Heaters Block heaters are recommended on all standby applications where the generator is subject to temperatures below 60 ° F( 1 6 ° C) and are available as installed accessories on all generator sets.
TP-5700 7/93 21 Section 5 Exhaust System Section 5 Exhaust System Proper installation of the exhaust system is essential to obtain satisfactory performance from a generator set. The most important factor is that the installed system must not exceed the engine manufacturer ’s maximum exhaust back pressure limit.
TP-5700 7/93 22 Section 5 Exhaust System 5.1 Flexible Section A section of flexible exhaust line should be installed within 2 feet (51 mm) of the engine exhaust outlet. This limits the stress on the engine exhaust manifold or turbocharger resulting from engine motion on its vibration mounts and temperature-induced changes in pipe dimensions.
TP-5700 7/93 23 Section 5 Exhaust System 5.4 Double -Sleeve Thimbles If the exhaust pipe should need to pass through a wall or roof, an exhaust thimble must be used to prevent exhaust pipe heat from being transmitted to the combustible material.
TP-5700 7/93 24 Section 5 Exhaust System Notes.
TP-5700 7/93 25 Section 6 Fuel Systems Section 6 Fuel Systems When planning an installation, check state and local regulations regarding fuel storage and handling.

TP-5700 7/93 27 Section 6 Fuel Systems Flexible connections must be used wherever there may be relative motion between piping and supplied equipment. Always use flexible lines at the engine connections. These should be a minimum of six inches (15.3 cm) long.
TP-5700 7/93 28 Section 6 Fuel Systems 6.5 Auxiliary Fuel Pumps Engine-driven fuel transfer pumps usually develop a maximum of 7 psi (48 kPa) pressure and have a lift capacity of 4-6 feet (1.
TP-5700 7/93 29 Section 6 Fuel Systems 6.6 Gasoline Fuel Systems Due to code restrictions which do not allow storage of more than one gallon (3.8 L) of gasoline inside a building, gasoline fuel systems are usually limited to housed generator sets installed outdoors or portable trailer-mounted units.
TP-5700 7/93 30 Section 6 Fuel Systems 6.7 Natural or LP Gas Fuel Systems Natural and LP (liquified petroleum) gas fuel systems should be designed and installed in accordance with the requirements of NFP A 54, National Fuel Gas Code, and all applicable local codes.

TP-5700 7/93 32 Section 6 Fuel Systems 6.8 Flexible Connector An approved flexible connector should always be used between stationary gas piping and the engine-mounted fuel system components. It should be at least six inches (15.3 cm) long or as recommended by the generator supplier based upon engine specifications.
TP-5700 7/93 33 Section 6 Fuel Systems 6.1 1 LP Gas Fuel Characteristics LP gas is supplied as a liquid in pressure tanks. It is easily adaptable to stationary applications where complete independence of an outside fuel supply is required.
TP-5700 7/93 34 Section 6 Fuel Systems 6.15 Natural Gas Natural gas is in a vapor state as supplied from the utility . This fuel system, therefore, consists of the same basic components and is used in the same general sequence as LP gas systems.
TP-5700 7/93 35 Section 7 Electrical Requirements Section 7 Electrical Requirements Before installing the generator set, provide for electrical connections through conduit to the transfer switch and other accessories for the generator set. Carefully install the selected generator set accessories.
TP-5700 7/93 36 Section 7 Electrical Requirements 7.2 Electrical Connections Several electrical connections must be made between the generator set and other components of the system for proper operation. Because of the large number of accessories and possible combinations, this manual does not address specific applications.
TP-5700 7/93 37 Section 7 Electrical Requirements 7.4 T erminal Connector T orque Use the torque values shown in Figure 7-4 or Figure 7-5 for terminal connectors. Refer to UL-486A, UL-486B, and UL-486E for information on terminal connectors for aluminum and/or copper conductors.
TP-5700 7/93 38 Section 7 Electrical Requirements 7.5 Automatic T ransfer Switches A typical standby system has at least one automatic transfer switch connected to the generator set output to automatically transfer the electrical load to the generator set if the normal source fails.
TP-5700 7/93 39 Section 7 Electrical Requirements 7.9 Remote Emergency Stop Switch The emergency stop switch allows immediate shutdown of the generator from a remote location. If the emergency stop switch is activated, the emergency stop lamp on the generator controller lights and the unit shuts down immediately .
