Regarding the circulating fluid pipings, consider carefully the suitability for shutoff pressure, temperature and circulating fluid. If the operating performance is not sufficient, the pipings may burst during operation. 2. Select the piping port size which can exceed the rated flow. For the rated flow, refer to the pump capacity table. 3. When tightening at the circulating fluid inlets and outlets, drain port or overflow outlet of this product, use a pipe wrench to clamp the connection ports. Piping 4. For the circulating fluid piping connection, install a drain pan and wastewater collection pit just in case the circulating fluid may leak. 5. This product series consists of circulating fluid temperature controllers with built-in tanks. Do not install equipment on your system side such as pumps that forcibly return the circulating fluid to the unit. Also, if you attach an external tank that is open to the air, it may become impossible to circulate the circulating fluid. Proceed with caution. Electrical Wiring 1. Grounding should never be connected to a water line, gas line or lightning rod. 1. Communication cables should be prepared by the customer. 2. Ensure a stable power supply with no voltage surges and distortion. In particular, operating failure can result when the voltage ramp rate (dV/dt) exceeds 40 V/200 μ sec at the zero cross-over point. dV dV dt dt = Voltage ramp rate Time Voltage HRS050-W Series HRS 1296
