It may be necessary to adjust static loop pressure by adding water after the unit has run for the first time Loop static pressure will also fluctuate with the seasons Pressures will be higher in the winter months than during the cooling season This fluctuation is normal and should be considered when charging the system initially Ensure the pump provides adequate flow through the unit by checking pressure drop across the heat exchanger Usually 2 25 3 0 gpm of flow per ton of cooling capacity is recommended in earth loop applications VERSATEC BASE SERIES INSTALLATION MANUAL Open Loop Ground Water Systems Typical open loop piping is shown below Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation Use a closed bladder type expansion tank to minimize mineral formation due to air exposure Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in unit capacity data tables in the specification catalog 1 5 2 gom of flow per ton of cooling capacity is recommended in open loop applications Due to only minor differences in flow rate from low to high only one solenoid valve should be used The valve should be sized for full flow Open System Groundwater Application Unit Supply Aux Heat Supply Flexible Duct Collar Rubber Bladder Expansio
