To reduce the possibility of a fire or explosion, be careful when working around gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep all cigarettes, sparks, and flames away from fuel and all fuel-related parts. PH2700PRI SM 11-09-2010...
2.3 Service rules 1. Use genuine POWERHOUSE® or POWERHOUSE®-recommended parts and lubricants or their equivalents. Parts that do not meet POWERHOUSE® design specifications may damage the engine. 2. Always install new gaskets, O-rings, etc. when reassembling. 3. When tightening bolts or nuts, begin with larger-diameter or inner bolts first and tighten to the specified torque diagonally, unless a particular sequence is specified.

The choke on the PH2700PRi operates automatically. When the unit is off, the choke will return to the closed position. In some cases, the choke on the PH2700PRi may close too slowly or open too fast. Both conditions can cause difficulty starting the unit. Read below to see if one or both conditions are present.

Note, The Economy Switch automatically turns off when running in parallel. Two separate PH2700PRi models can run in parallel to increase the total output to a maximum load of 5400 W (Rated output, 5200 W). You can also run a PH2700PRi and a PH2100PRi in parallel. The maximum output will be 4200 W (Rated output, 4000 W).
The required output of the electrical appliance cannot exceed the rated output of the generators. The special parallel cable for the PH2700PRI and PH2100PRi is only applicable to the parallel operation of two POWERHOUSE generators. It cannot be used for paralleling three or more generators or running two different brands of generators.

1. During normal operating conditions, the output indicator lights (Green) will remain illuminated. 2. If the generators are overloaded (in excess of 5200W when using two PH2700PRi units) the overload indicator light (red) will flash slowly on only one generator. The indicator lights on the other unit and the parallel kit will all be off.
The green indicator light on both generators and the parallel kit should come on within 15 seconds. Repeatedly pressing the reset button without correcting the short circuit may cause permanent damage to the generators and/or parallel kit. PH2700PRI SM 11-09-2010...
