When installing the product, keep the space for maintenance as shown below. 800 mm or more 800 mm or more 800 mm or more 800 mm or more 400 mm or more Required installation space Piping Caution 1. Regarding the circulating fluid and facility water pipings, consider carefully the suitability for temperature, circulating fluid and facility water. If the operating performance is not sufficient, the pipings may burst during operation. Using corrosive materials such as aluminum or iron for fluid contact parts such as piping may cause clogging or leakage in the circulating fluid and facility water circuits. Provide protection against corrosion when you use the product. 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 drain port of this product, use a pipe wrench to clamp the connection ports. 4. Supply water pressure to the automatic fluid fill port of this product should be 0.2 to 0.5 MPa. This product has a built-in ball (float) tap. If you attach it to the faucet of a sink etc. it will automatically supply water to the rated fluid level of the tank (halfway between HIGH and LOW.) If the water supply pressure is too high, the pipes may burst during use. Proceed with caution. 5. Ensure that piping is connected to the overflow port so that the circulating fluid can be exhausted to the drainage pit when the fluid level in the tank increases. 6. For the circulating fluid piping connection, install a drain pan and wastewater collection pit just in case the circulating fluid may leak. 7. This product series are constant-temperature fluid circulating machines 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. 3. Refer to the Operation Manual for this product, and secure an installation space that is necessary for the maintenance and ventilation. 1. The air-cooled type product exhausts heat using the fan that is mounted to the product. If the product is operated with insufficient ventilation, ambient temperature may exceed 45°C, and this will affect the performance and life of the product. To prevent this ensure that suitable ventilation is available (see below). 2. For installation indoors, ventilation ports and a ventilation fan should be equipped as needed. 2000 mm or more 800 mm or more 800 mm or more 800 mm or more 400 mm or more HRSH250-A Ventilation Required installation space for ventilation and maintenance 3. If it is impossible to exhaust heat from the installation area indoors, or when the installation area is conditioned, provide a duct for heat exhaustion to the air outlet port of this product for ventilation. Do not mount the inlet of the duct (flange) directly to the air vent of the product, and keep a space larger than the diameter of the duct. Additionally, consider the resistance of the duct when making the air vent port for the duct.
