Refer to front matter 41 for Safety Instructions and pages 1246 to 1249 for Temperature Control Equipment Precautions. 1. Mount and install horizontally. When mounting, fix the foot of the Chemical Thermo-con by tightening the screws to the specified torque below. 1. Applicable fluids For the compatibility between the material of components and fluid, refer to “Applicable Fluids” (page 1436). Please contact SMC for fluids other than those described on the check list. 2. Caution for the use of fluids with high permeation When the Chemical Thermo-con is used for a fluid with high permeation into fluorine resin, the permeation can affect its life. If the fluid also generates corrosive gas, perform N2 supply and exhaust (N2 purge) inside the heat exchanger. 3. Caution for the use of deionized water If deionized water is used, bacteria and algae may grow in a short period. If the Chemical Thermo-con is operated with bacteria and algae, the performance of the heat exchanger may deteriorate. Exchange all deionized water regularly depending on the conditions (once a month as a guide). 4. Prohibition of small flow rate Be sure to avoid operation with the circulating pump stopped or with extremely small flow rate of recirculating fluid (7 L/min or less for water). Otherwise, the Chemical Thermo-con will repeat change cooling and heating operation, which may shorten the life of the Peltier element significantly, and it will become unable to control the temperature accurately. When the circulating pump is stopped, stop the temperature control of the Chemical Thermo-con as well by using the remote ON/OFF function. 5. Operating pressure range of circulating fluid The operating pressure range is 0 to 0.35 MPa. Do not use with negative pressure which can cause the Chemical Thermo-con to fail. (Specifically, install the heat exchanger at the secondary (discharge) side of the circulating pump.) Also, avoid excessive pressure being applied to the circulating fluid circuit by a clogged filter or fully closed valve. 6. Prohibition of fluid pulsation If a pump generating pulsation is used, install a damper to absorb the pulsation directly before the Chemical Thermo-con. Fluid pulsation can break the Chemical Thermo-con. 1. The set value can be written to EEPROM, but only up to approx. 1 million times. In particular, pay attention to how many of times the writing is performed using the communication function. 1. Prevention of electric shock and fire Do not operate the switch with wet hands. Also, do not operate the Chemical Thermo-con with water or fluid left on it. 2. Action in the case of error If any error such as abnormal noise, smoke, or bad smell occurs, cut off the power at once, and stop supplying faciity water. Please contact SMC or a sales distributor to repair the Chemical Thermo-con. 3. Regular inspection Check the following items at least once a month. The inspection must be done by an operator who has sufficient knowledge and experience. a) Check of displayed contents. b) Check of temperature, vibration and abnormal sounds in the body of the Chemical Thermo-con. c) Check of the voltage and current of the power supply system. d) Check for leakage and contamination of the circulating fluid and intrusion of foreign objects to it, and subsequent replacement water. e) Check for leakage, quality change, flow rate and temperature of facility water. 4. Wearing of protective clothing Some fluids can be dangerous when handled incorrectly. Wear protective clothing for safety during maintenance. In particular, observe the MSDS of the circulating fluid, and wear protective goggles, gloves and mask for the operation of the Chemical Thermo-con accompanied with the use of fluids. 1439 HRG HRS HRZ HRZD HRW HEC HEB HED HEA IDH
