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.

Yes, I would recommend this to a friend (1)
no problems
Bought this unit after hurricane Irene. Also installed a transfer switch. Sat in my garage until Sandy hit. Hooked up the cable and it has been generating power for us for 2 weeks with no problem. Runs well pump, oil fired furnace and hot water heater, refrigerator, microwave, toaster oven, washing machine, some lights, and sump pump (which has not come on). We run it from 5 pm until we go to bed and again in the morning before work. It has more than paid for itself already and uses very little gas.

Bought generator after Sandy hit last year through Generator Direct. Delivery was quick and as promised. Didn't get the lift service off truck but delivery guy was very helpful. He actually put the generator on a dolly and helped me push it up my driveway and into my back yard. Generator worked great (ran on/off for 40 hours). Only issue is that the engine misfires when choke is completely pushed in. I pulled it out a little until engine ran fairly smoothly. Didn't affect performance. Probably needs minor adjustment.

Just the Right Size
Based on the transfer switch system installed, the electrical contractor recommended a minimum 7500 watt unit.  With all the operating features, this is the perfect unit.

Can this generator power up a 1800 square foot house?
Anthony F on Oct 21, 2016
BEST ANSWER: It depends on what kind of applications you are looking to power within the house. 8,000W is a good amount, but it will not be able to power central heat, Fridge/Deep Freeze, lights, water heater at the same time
