1. Pressure drop data is based on 15% (by volume) methanol antifreeze solution on the source side and pure water on the load side.
2. Pressure drop data accurate within ±25%.
3. Interpolation of unit pressure drop data is permissible; extrapolation is not.
4. Due to variations in installation, actual unit performance may vary from the tabulated data.

Record information on the Unit Start-up Form
Equipment should be in operation for a minimum of 10 minutes in heating mode
1. Determine flow rate in gallons per minute
a. Check entering water temperature
b. Check entering water pressure
c. Check leaving water pressure
Once this information is recorded, find corresponding entering water temperature column in Specification Manual for unit.
Find pressure differential in PSI column in Spec Manual. Then read the GPM column in Spec Manual to determine flow in GPM.
2. Check leaving water temperature of unit.
FORMULA: GPM x water temp diff. x 485 (antifreeze) or 500 (fresh water) = HE or HR in BTU/HR
A 10% variance from Spec Manual is allowed. Always use the same pressure gauge & temperature measuring device.
Water flow must be in range of Specification Manual. If system has too much water flow, performance problems should be
expected.
