Alcohols and glycols are commonly used as antifreezes, however your local sales manager should be consulted for the antifreeze best suited to your area.
THE SMART SOLUTION FOR ENERGY EFFICIENCY Genesis Large (GL) Series R e v. : 1 3 A p r i l , 2 0 0 9 B Ground-Water Heat Pump Applications devices are typically an orifice of plastic material that are designed to allow a specified flow rate. These are mounted on the outlet of the water control valve. On occasion, these valves can produce a velocity noise that can be reduced by applying some back pressure. This is accomplished by slightly closing the leaving isolation valve of the well water setup.

Ideal tension is the lowest tension at which the belt will not slip under peak load conditions. 2. Check tension frequently during the first 24-48 hours of operation. 3. Over tensioning shortens belt and bearing life. 4. Keep belts free from foreign material which may cause slip. 5. Make V-drive inspection on periodic basis.
