Application data (cont) per ton (6.5 to 10.8 liters per kW). To achieve this volume, it is often necessary to install a tank in the loop. Tank should be baffled to insure that there is no stratification and that water (or brine) entering tank is adequately mixed with liquid in the tank. GOOD GOOD Co...

Page 6 - Hot gas bi^pass usage, while frequently specified, is not; Selection procedure

Time clock shutdown (or other controlled shutdown not associated with leaving chilled water temperature) requires use of accessory demand limit control module. Second step of the demand limit control (0-50% of capacity) is set for 0 (zero) capacity. This allows unit to go through a normal pumpout cy...
