Stop: If running at a fluid temperature below 48°F or if the chiller will be installed in a climate
where the ambient temperature may get below 40°F you must use a water and glycol mixture
at a ratio that protects the fluid from freezing to approximately 25°F below the lowest expected
set point temperature or the lowest expected ambient temperature whichever is lower. See
Section 8.1 and 8.2 of this manual before operating your chiller. Regular testing of your glycol
protection is critical.

  • Page 16: Air-Cooled Condenser

    Condenser Air Filtering. Use a filter that produces very low air flow restrictions. Generally a disposable fiberglass filter with a MERV rating of 2 - 3 provides adequate air filtration. The purpose of the filter is to prevent large particles such as dust, lint and debris from fouling the condenser. You should be able to see through the filter media. Using restrictive filter media can cause loss of chiller capacity, difficulty running in warm weather and fan motor overheating. Typical Filter materials. ADVANTAGE ENGINEERING, INC.
