Troubleshooting Guide
* IMPORTANT: In regards to the CC-5, CC-12, CC-25 and CC-40 the 5, 12, 25 and 40 represent the total tempered
water capacity (in GPM) of the unit. The following formula should be used to determine how much hot water or
condensate can be cooled:
B-C X Model = gallons of hot liquid or condensate Example: 135 - 50 X 5 (CC-5) = 3.25*
H-C 180 - 50
*3.25 gal x 8.33 lbs per gallon x 60 = 1624 lbs per hour
Where:
B = Set point of tempering valve (preset to 135°F)
C = Cold water temperature
H = Hot water temperature or condensate temperature
* In the example, Model CC-5 (5 gpm) can handle 3.25 gpm of 180°F of hot liquid. If cold water temperature or
discharge temperature changes - the capacity will change.
