Min. Series HRZ Specific Product Precautions 2 Be sure to read this before handling. Refer to front matter 41 for Safety Instructions and pages 1246 to 1249 for Temperature Control Equipment Precautions. Mounting/Installation Caution 1. Avoid using this product outdoors. 2. Install on a rigid floor which can withstand this product’s weight. 3. Install a suitable anchor bolt for the anti-quake bracket taking into consideration the customers floor material. 4. Avoid placing heavy objects on this product. Piping Caution 1. Regarding the circulating fluid pipings, consider carefully the suitability for shutoff pressure, temperature and circulating fluid. If the operating performance specifications are regularly exceeded, the pipings may burst during operation. 2. The surface of the circulating fluid pipings should be covered with the insulating materials which can effectively confine the heat. Absorbing the heat from the surface of pipings may reduce the cooling capacity performance and the heating capacity may be shortened due to heat radiation. 3. When using fluorinated liquid as the circulating fluid, do not use pipe tape. Liquid leakage may occur around the pipe tape. For sealant, we recommend that you use the following sealant: SMC Part No., HRZ-S0003 (Silicone sealant) 4. For the circulating fluid pipings, use clean pipings which have no dust, oil or water moisture inside the pipings, and blow with air prior to undertaking any piping works. If any dust, oil or water moisture enters the circulating fluid circuit, inferior cooling performance or equipment failure due to frozen water may occur, resulting in bubbles in the circulating fluid inside the tank. 5. The reciprocating total volume of the circulating fluid pipings must be less than the volume of the sub-tank. Otherwise, when the equipment is stopped, the in-built alarm may activate or the circulating fluid may leak from the tank. Refer to the specifications table for the sub-tank volume. 6. Select the circulating fluid pipings which can exceed the required rated flow. For the rated flow, refer to the pump capacity table. 7. For the circulating fluid piping connection, install a drain pan just in case the circulating fluid may leak. 8. Do not return the circulating fluid to the unit by installing a pump in the customer system. 3. This product is installed with a breaker with the following operating characteristics. For the customer’s machine (inlet side), use a breaker whose operating time is equal to or longer than the breaker of this product. If a breaker with shorter operating time is connected, the customer’s machine could be cut off due to the inrush current of the motor of this product. Electrical Wiring Caution 1. Power supply and signal cable should be prepared by the customer. 2. Provide a stable power supply which is not affected by surge or distortion. If the voltage increase ratio (dV/dt) at the zero cross should exceed 40 V/200 μsec., it may result in a malfunction.
