100 mm or more Leave space 100 mm or more Discharge Intake Intake 100 mm or more Intake Leave space 150 mm or more 1. This catalog shows the specifications of the Thermo-con. 1. Check detailed specifications in the separate “Product Specifications”, and evaluate the compatibility of the Thermo-con with customer’s system. 2. Although the protection circuit as a single unit is installed, the customer is requested to carry out the safety design for the whole system. System Design Warning Operating Environment/Storage Environment Warning Circulating Fluid Caution 1. Use tap water or fluid which will not damage the wetted parts material as described in this catalog’s specifications. (PPE, PP glass 10%, Alumina ceramics, Carbon, EPDM, Stainless steel 303, Stainless steel 304, PE, PP, NBR) 2. Deionized water (with an electrical conductivity of approx. 1 μS/cm) can be used, but may lose its electrical conductivity. It is not necessary to leave space for ventilation. Install the product while taking working space for installation and maintenance into account. However, ventilation must be also considered so that ambient temperature does not excessively rise. Facility Water Caution Series HEC-W Specific Product Precautions 1 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. Operating Environment/Storage Environment Warning Handling Warning 1. Thoroughly read the Operation Manual. Read the Operation Manual completely before operation, and keep this manual available whenever necessary. 2. If the set temperature is repeatedly changed by 10°C or more, the Thermo-con may fail in short periods of time. 1. Keep within the specified ambient temperature and humidity range. Also, if the set temperature is too low, condensation may form on the inside of the Thermo-con or the surface of piping even within the specified ambient temperature range. Dew condensation can cause failure, and so must be avoided by considering operating conditions. 2. The Thermo-con is not designed for clean room usage. The pump and fan generate dust. 3. Low molecular siloxane can damage the contact of the relay. Use the Thermo-con in a place free from low molecular siloxane. 4. Installation conditions If the space for the intake and discharge of air is insufficient, the amount of transferred air will decrease, which can impair the performance and life of the product. Therefore, keep the conditions illustrated below for installation. Also, if ambient temperature is expected to be over 35°C, vent or exhaust air to prevent the increase of ambient temperature over 35°C. 1. If the temperature of the facility water is too low, it can cause formation of dew condensation inside the heat exchanger. Supply facility water with a temperature over the atmospheric dew point to avoid the formation of dew condensation. 2. If the facility water piping is connected to multiple machines, the facility water exchanges heat at the upstream side and its temperature will become higher as it goes downstream. Limit the number of connected Thermo-cons to two per facility water system, and if more than two Thermo-cons are to be connected, increase the number of systems. 1410
