Thursday was our launch day, and due to other things, we were not able to try our new A/C. Saturday morning we attached the dockside water hose to the A/C pump and started the unit, all my double clamped hose fittings were checked for leaks,finding none, we connected the AC raw water pump to the hose I installed from a three way valve,bled the air from the hose, and now we are airconditioned and heated. The unit is a little louder than I had hoped, but, it works fine.It quickly brought the temp. from 50 to 68 degrees, and maintaind that quite easily during the day. The new bulkhead along the setee, and louvered doors I installed make the area look like it was built like that from the factory. Total install time was about 27 hours. Questions?
