2. SAFETY PRECAUTIONS

55

Обращение

Current network which feeds the unit’s motor and controls must be additionally protected by a fuse to prevent consequences of shunt fault.

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.

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.

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.

Use screws appropriate for the material which the base is made of.

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.

-t

Avoid substances and impurities in the heat medium causing copper corrosion.

Install the unit on a firm base or surface, which can stand its weight filled with water.

Проверьте наличие заземления. Не допускается использование щита управления без заземления, это может привести к повреждению имущества, травмам и гибели персонала.

Во время монтажа, запуска, ремонта и обслуживания щита управления соблюдайте все правила и нормы безопасности.

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 o� by compressed air.

NEW

Provide protection of a fan against overheat by connecting protection devices to contacts of fan temperature sensor.

The air heater PROTON is an element of a heating system. It is designed for heating air and its even distribution in buildings. Its work is based on axial fan functioning, which charges the air and pass it through a copper-aluminum heat exchanger in which the heat medium (hot water) flows at certain temperature. Heated air is supplied into a room and is directed to the working area by directing louvers.

Major components of the air heater PROTON EX

Casing

Fan

Heat exchanger

Directing louvers

A 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”). Copper-aluminum heat exchanger is distinguished by high e�ciency, 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 130 °C/1,6 MPa.

Protection-proof axial fan of the air heater PROTON EX provides even air distribution on heat exchanger’s surface. The construction and material of the fan prevents sparks and local temperature increase in motor windings. Overheat protection is provided by a thermistor sensor, not a temperature sensor as for standard motors. The motor meets European requirements on explosion safety. Rated power supply of PROTON EX fans is 3~400 V/50 Hz. Motor protection rating is IP44 (EN60529), isolation class THCL155, protection class II2Gc ExeIIB T3. Operating temperature range is-20 °C to +40 °C.

Взрывозащищенный вентилятор PROTON EX обеспечивает равномерное распределение потока воздуха по всей поверхности теплообменника. Конструкция и материал вентилятора не допускают искрообразования и локального повышения температуры на обмотках двигателя. Защита от перегрева осуществляется за счет специального термисторного датчика, а не термоконтакта, как в стандартных двигателях. Вентилятор соответствует европейским нормам по взрывобезопасности. Номинальное питание вентиляторов в серии EX осуществляется от источника 3~400 В/50 Гц. Степень защиты двигателя IP44, класс изоляции – THCL155, класс защиты II2Gc ExeIIB T3. Диапазон температур во время работы составляет от -20 до +40 °C.

Metal casing is made of elements dyed by protection cover that provides long-time protection against corrosion and conforms with European quality and design standards.

Монтаж аппарата PROTON E 15Installation of a few units Recommendations of placing units

Noncompliance with the minimal distance (0,25 m) from a wall or ceiling will lead to wrong operation of the air heater which, in turn, will influence the useful life of the equipment.

When connecting the heat medium pay your attention that manifolds of the air heater must be fixed. For this use two keys: one – for fixing heat exchanger manifolds, the second – for connecting it to the system.

Examples of placing the equipment which provide even distribution of heat in a building are presented on the illustrations.

When mounting a few air heaters PROTON it is recommended to stick to the following distances between units: installation in one line – 5-9 m, installation opposite to each other – 27-35 m, installation one by one – 12-15 m.These distances are just recommendations. The installer should also take into account dimensions and shape of a building, its encumbering, and recommendations of specialists on a project.
