Installation Questions
For the Fresair S8 Roof Air Conditioner
Professional installation is recommended but can be accomplished by a skilled owner. A hole to accommodate the airbox needs to be cut from the roof (template provided).
The unit drops onto the roof and is sealed by foam and silicone gel and mounted using 4 bolts. The water lines and power line, contained within a single harness, are run from the unit to the reservoir and battery. The harness contains two water pipes, one to feed the unit with water, the other to return water from the unit to the remote reservoir, as well as the 12V power cable.
On golf carts, the loom runs over the top of the roof and down one of the roofs supports into the cart body. We also provide a unit where the harness runs under the roof, especially clean when you have a headliner.
For golf carts, there are many different roof types out there, so the strength of the roof, curvature of the roof, and where the mounting bolts are to be located need to be analyzed. There are multiple mounting bolt patterns though so there are options to work with virtually any roof. If your roof cannot hold a 25lb weight, support brackets need to be added on the underside of the roof, but most roofs are fine.
The harness runs towards the back of the roof and generally to the left down the rear left roof support strut and into the body of the cart. Depending upon your cart a 1” hole may need to be cut to allow the harness to pass through the body.
The harness then needs to be connected to the reservoir and 12V power converter. There are two types of reservoirs, an 8L model that fits under the seat where the batteries are located (if you have space) and a 5L model that is usually mounted under the left rear wheel-well and connected through the body to a “gas-cap” style remote fill. The water pipes then need to be connected to the reservoir and the 12V power cable to the converter.
No. With electric golf carts, the power source needs to be connected to a converter. This will draw power equally from your battery pack rather than draining one battery. Most golf carts already have a 12V converter fitted to run components such as lights and sound systems.
Yes, but please remember that if the engine is not running the battery will drain. The system does draw minimum power though (< 10A/h) so it is not a large load on the battery, however, you should run the engine occasionally so the alternator is charging the battery.
Flat roofs work the best, but as long as the system is flat or facing down slightly towards the front (the return pump gathers water from the front of the unit) the system will function properly. The unit weighs about 25lbs, so your roof will need to be able to support that weight or will need support bars added. Contact an authorized Fresair dealer to have your cart inspected by a certified tech.
For golf carts, there are two options: the 8L under the seat (size of a battery) & the 5L remote fill (normally installed within a wheel well). Both reservoirs are not visible to the eye when installed and offer a very convenient waist-high filling system.
Yes, water consumption is based upon the exterior ambient temperature but you should get an absolute minimum of 4 hours of a cooling sensation.
The following video shows a few possible locations for the 5L and 8L reservoirs on a golf cart.
