Section III - Installation

Clean air is essential for your Quincy compressor. Always select a source providing the cleanest air possible. When an outside air source is used, keep all piping as short and direct as possible.

Minimum water quality is listed in Table 3-2. The quality of the cooling water should be tested regularly, especially when using an open cooling tower.

Contact the factory if you plan to use a water/glycol coolant, salt or brackish water.
