The rear side is opened. Intake 100 mm or more 100 mm or more Discharge The rear side is closed. Intake 200 mm or more 200 mm or more Discharge The rear side is opened. Intake 500 mm or more 500 mm or more Discharge The rear side is closed. Intake 500 mm or more 500 mm or more Discharge System Design Warning Handling Warning Operating Environment/Storage Environment Warning Radiation Air Caution Note) The space must be 500 mm or more. Be sure that the ambient temperature is within the specification range. Series HEC-A 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. 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. 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 10oC 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. It generates dust from the pump inside the unit and the cooling fan. 3. Low molecular siloxane can damage the contact of the relay. Use the Thermo-con in a place free from low molecular siloxane. 1. The inlet for radiation air must not be exposed to particles and dust as far as possible. 2. Do not let the inlet and outlet for radiation air get closed. If radiation is prevented, the set temperature may not be achieved depending on the value of the set temperature and the load. Keep a space of 100 mm for opened rear side or 200 mm for closed rear side respectively. 1394
