If the customer has only the coil size or opening size of the unit then:
add 5" to the height measurement for Standard P and/or S Model
add an additional 4" to the height measurement for CE-100 Model with reservoir (total of 9")
add 6" to the width measurement for either P and/or S or CE-100 Model

NOTE: You will need 1.5 square feet of pre-cooler per ton. (Maximum to 550 feet per minute per square foot to prevent water carry over.)

Is the unit a multi-coiled group?
This would mean that one pre-cooler would be needed for each coil section of the unit.
For example: If a unit has coils on 2 sides, the main pre-cooler would be an "A" series pre-cooler with all the necessary controls and the other unit(s) would be "B" series units with only a needle valve for controlling the water flow over its own media section.
