Air conditioning unit 7.5 ton, self-contained,


7.5 Ton, Self-Contained, Air Conditioning Unit
The inlet connection is a union threadpiece and the oulet is a union tailpiece. The mating unions are provided (threaded loosely to the condenser head inlet and water regulating valve outlet). The connection pipe sizes are, Inlet: 1.25 inch and Outlet:1.25 inch.
This unit is designed to mount on a solid surface with (4) 3/4-inch bolts & nuts, with washers. However, the unit can be mounted on structral rails. The rails must be at least 4-1/2 inches wide and positioned at the front, back and sides of the unit.
Removable Plenum comes attached.
The thermostat can be adjusted to maintain constant room temperature between 60 and 95F.
The motor pulley is a variable speed pulley that can be adjusted to maintain the proper constant blower speed.
Installation, Operating and Maintenance manuals are included.
Please Note: This unit was designed to be used with sea water on a military vessel (reasoning for 70/30, copper/nickel). If land based operation is desired a water cooling tower may be required. These units are water cooled and the water discharge can either (a) be used in conjunction with a water cooling tower to recycle the water in a closed loop system or (b) the discharge city water can be sent down the drain becoming very costly at the end of the month with so many gallons of water being used. If you have questions, or need additional information, please feel free to contact me with your concerns.
