1. ITRODUCTIO The company PROTO GROUP LLC thanks you for choosing air heaters PROTO. This manual is an integral part of the product and must always accompany it, and should be transferred to the user. To provide proper wiring and application of the unit, please, study this manual thoroughly before installation. We recommend keeping the manual safe in order to address it during operation. The user should strictly follow safety instructions while installing, using and servicing the unit. The access to the unit must be restricted for unauthorized and unqualified personnel. The appropriate training of the maintenance staff should be provided. The manufacturer disclaims any responsibility for damages caused by wrong installation and misuse of the unit. The manufacturer disclaims any responsibility for damages done by people who didn t study the manual. The manufacturer preserves the right to introduce any amendments to the manual without prior notification. The manufacturer preserves the right to alter the construction which doesn t impact its functioning and basic technical parameters. The air heater is intended only and exclusively to be installed and used for purposes which it has been designed. Any misuse or noncompliance with the manufacturer s instructions may lead to property damages, personnel injuries or death. The user has to take measures to eliminate possibilities of misuse of the unit. 3
2. SAFETY PRECAUTIOS Before any actions connected with the air heater, please, study this manual to provide safety. Installation and connection of the equipment to pipelines and networks must be performed by qualified personnel only, having appropriate access. During installation, start-up, repair and maintenance of the air heater follow the safety rules. Install the unit on a firm base or surface, which can stand its weight filled with water. Use screws appropriate for the material which the base is made of. Check correctness of connections of the system, accordance of the heat medium parameters to the parameters indicated on the rating plate as well as leak proof of joints before filling in the heat medium. Avoid substances and impurities in the heat medium causing copper corrosion. Check compliance of parameters of the electrical supply network to the ones indicated on the unit s rating plate before connecting to the power supply. Check grounding. Prohibit the use of the unit without grounding as it may cause property damages, personnel injuries and death. Current network which feeds the unit s motor and controls must be additionally protected by a fuse to prevent consequences of shunt fault. Thermal protection of fan s motor is built-in and works in a standalone mode. -t While the air heater is operating under low temperatures, the user must provide protection of the water heat exchanger or use heat medium with special additives preventing copper corrosion. To prevent defrosting of the air heater s heat exchanger when circulation of the heat medium is stopped during a heating period under outdoor temperatures lower than 0 C, you need to drain the heat medium from the heat exchanger and blow it off by compressed air. 4
3. GEERAL IFORMATIO ErP 2015 PROTO AST It is designed for effective heating of the premises with the ceilings not higher than 5 m. It enables the airflow to be distributed optimally within the space, which provides fastest possible heating. The series is equipped with multi-speed. In order to further improve energy saving, the EC-motor can be used. Application of PROTO AST 2-5 m PROTO AST is to be used in low ceiling buildings and where even air distribution, not zonal, is required. They are installed under the ceiling that provides free air circulation even at decreased flow speed. Advantages: even air distribution, fast and effective heating of a building. It is to be used in small production facilities, parking, green houses, and workshops. 5

5. COSTRUCTIO Major components of the air heater PROTO AST Casing The casing consists of a black plastic diffusor and a metal front panel (anemostat), dyed by powder paint. The anemostat is an air distributor serving for supplying and even air distribution in the room as well as lowing air stream speed. Fan The fan is fixed in a special diffuser on the back of the unit, thanks to which air flow is evenly distributed on the heat exchanger s surface. This provides its most effective application. This solution decreases noise level created by the flowing air. The fan is equipped with a special grill which protects the heater from falling in of debris, leaves etc. as well as prevents possible personnel injures or death caused by rotating fan s blades. Rated power supply of PROTO AST fans is 230 /50 Hz. Motor protection grade is IP54. Operating temperature is up to +55 C. Heat exchanger The heat exchanger consists of copper tubes and aluminum lamellas pressed on them. It is equipped with copper pipes with threading connection (external thread 3/4 ). The copper-aluminum heat exchanger is distinguished by high efficiency, is not exposed to corrosion if you don t use substances and impurities in the heat medium causing copper corrosion. Maximal parameters of heat medium supply are 105 C/1,6 MPa. 7
