Freight Orders

Freight deliveries require a delivery time be scheduled and someone must be present at the time of delivery to inspect and sign for the merchandise. A representative from the freight carrier will call the phone number entered at checkout to schedule the delivery.

Liftgate Service

For freight deliveries, you have the option of adding a liftgate to your delivery. A liftgate is the device that lowers a product from the truck to ground level.

CPO recommends adding liftgate service for freight deliveries exceeding 100 lbs if you do not have a loading dock or fork lift at the delivery address. Additional charges may apply. The liftgate option will be presented during the checkout process.

Please note that liftgate service only ensures the product is removed from the truck. We recommend you have the additional help of two to four people to move the product to its desired location because drivers are not required to assist.

Requesting liftgate service after ordering may result in additional charges and delays.

  • Q:

    Can the RTS14EZA1 transfer switch be used with this generator and replace the transfer switch that comes with this unit

      The RTS14EZA1 is too large. This 7KW generator is only designed for use with it's included switch.

  • Q:

    I see the unit comes with a trans switch
    and I have been told I can use it either natural gas or LP.
    My question is if I use it with natural gas do I need a regulator to control the gas flow
    and also what size gas pipe do i need coming from the house.
    Asked on 10/31/2012 by Bobby from Ct

      Gas flow is regulated by the generator, but to determine the correct pipe size you must first determine the pressure you have. this can be done by a qualified plumber.

      It should be serviced after every 200 hours of use, basically like getting an oil change in your car...

  • Q:

    Can someone explain (briefly) installation? I assume that I would need at least an electrician. (I'm not a DIYer when it comes to electricity!)

    Any info that can be provided is appreciated!

      First you will need to prep the location for the installation and place the composite pad on a firm and level surface. You will next place the generator on the pad. Then you will install the transfer switch (this is where a licensed electrician is very helpful), and wire it to the existing distribution panel in your home and and to the generator. You will next connect the fuel line (natural gas or propane, also helpful to have a licensed plumber for this step) to the generator. That is the simplified basics of installation. You can also download the installation manual from our site for detailed explanations of each step.
