NOTE: Charging procedures for MCHX units require very accurate measurement techniques. Charge should be added in small increments. Using cooling
charging charts provided, add or remove refrigerant until conditions of the chart are met. As conditions get close to the point on the chart, add or remove charge in
1/4 lb increments until complete. Ensure that all fans are on and all compressors are running when using charging charts.
