FOR THE QUEST 506 208/230V IS THERE A BASE OR LEG KIT THAT CAN BE PURCHASED SEPARATE?

The Quest 506 doesn’t come with a base or leg kit, and there isn’t a dedicated kit listed for it. The unit can be suspended or placed on the ground. However, the 6-inch Heat Pump Risers may also work as an alternative since they have a 2,000 lb weight capacity and the Quest 506 weighs around 300 lbs. You can check them here: http://hvacdirect.com/6-inch-heat-pump-risers-4pack-hpr-6.html The hanging diagram is also available on page 4 of the Quest 506 manual.
