1 Foreword These operating and installation instructions are a supplement for the TR series heater combined with a ventilator for systems which require greater external pressure. TR: Standard series with standard axial fan o No possibilities for extra air accessories TR-A: Heater with more powerful axial fan o Limited possibilities for extra air accessories. Maximum pressure 60Pa Duct outlet (max 60Pa) Fan box with dampers and/or filters No combination of these 2 options possible TR-C: Heater with centrifugal fan. o External pressures up to 0Pa (higher values on request) o Different accessories possible Duct inlet / outlet connection Fan box with optional dampers and/or filter panels Rooftop version Combinations of above. This installation and user manual for the TR heater is the leading document for the installation of this appliance. These operating and installation instructions deal with the specific matters that apply to supplementary use and installation of a centrifugal design. 2 Design 2.1 TR-series (standard heaters) These are standard TR heaters. There are NO air accessories available. The fans behind these units cannot cope with higher air resistance. 2.2 TR-A series These heaters have more powerful axial fans and can cope with external pressures up to 60Pa. This gives the possibility to add air accessories. Available models are 24 to 100kW. 2.2.1 TR-A with duct connection on front. The heater pulls its air from the room and blows it into an air duct. This duct needs to be dimensioned in such a way that the static pressure inside this duct does not exceeds 60Pa. Warning: When the air resistance in the duct is too high, the amount of air over the heater will reduce too much and the heat exchanger will overheat. This can lead to permanent damage of the heater!! TR TR-A duct connection max60 Pa 2.2.2 TR-A with fan box The TR heater sucks its air from a fan box from behind. Dampers and or filters can be mounted in this box, depending on the customer demands. The heater blows the air direct into the building. Annex to Instructions TR Centrifugal Version GB 139d Page 4/41

In this configuration it is not possible that the air is distributed through a duct system. This would give too much air resistance and would lead to overheating the heat exchanger. Warning: When the air resistance in the duct is too high, the amount of air over the heater will reduce too much and the heat exchanger will overheat. This can lead to permanent damage of the heater!! TR heater Filter + dampers Filter + dampers 2.3 TR-C TR heater with centrifugal fan The TR air heater with centrifugal system ventilator(s) is available with the following pressure: 60, 120, 180, 240 and 0 Pa.

4 Installation 4.1 General: General installing instructions are provided in the TR instruction manual for appliances with axial ventilators. This supplementary booklet presents specific installing instructions for the centrifugal and rooftop version of the TR. The appliance must have a clear suck and throw. If these are blocked the heater will overheat. There should not be materials within 5m in front of the heater when there is a free outlet. Pay particular attention to flammable materials Take into account the possibility to open the door of the heater for necessary service and maintenance work. Make sure that after fitting, there is no mechanical tension on any connected gas or electrical supplies. 4.2 Suspension / positioning 4.2.1 Suspension TR C basic and TR C with Fan box The heater is provided with fixing points for suspension, consisting of 4 or 6x M10 threaded sockets on top. Check and make sure that the support is strong enough. For the TR C with Fan box there is an C frame optional available. (8.7.2 / 8.7.4) 4.2.2 Positioning TR R Rooftop The TR Rooftop must be placed on a so called platform. - Rooftop frame - C frame (optional) See example drawing of the rooftop frame Chapter 8.7. Check if the support is strong enough. 4.3 Duct connection: The discharge side of the heater has a connection flange on which a duct can be fixed with M5 bolts. Dimensions: see chapter 8. The Rooftop version is also optional available with a discharge down flow module. 4.3.1 Air resistance and accessories TR Heater Filter + Damper Filter + Damper Annex to Instructions TR Centrifugal Version GB 139d Page 8/41

Application of basic accessories can imply following resistance losses: Fan box 20 Pa Dampers 10 Pa Filter panel (Class EU2), clean 40 Pa Fresh air grill 10 Pa Discharge down flow module 20 Pa 4.3.2 Minimum distance to bends or other appendages It is essential that the heat exchanger is being blown equally over the full frontal surface. If the air, for example only covers the lower part of the exchanger, the upper region will probably get no cooling and get overheated. De TR C heater should have at least 1 meter of straight duct with a cross section that is equal to that of the flange connection, behind the exchanger. If these conditions are not being fulfilled, the heat exchanger will get thermally overloaded. This will result in heater errors and damage to the exchanger (shorter lifetime). This can mean invalidation of warranty! 4.3.3 Air Duct This paragraph gives a general representation of the requirements a simple duct system must meet. The reader is referred to specialist installers for accurate calculations of more complicated systems. The table below shows the diameter of the appropriate size round air duct (standard sizes for spirally seamed ducting) for the given air displacement [m3/h] and acceptable speed of the air [m/sec]. The ducts must be airtight, internally smooth and sufficiently heat resistant. The ducting connection to the heater must be made of metal for a length of no less than 2 meters and run smoothly into the connector sizes of the appliance without any buffeting edges. Bends in square section ducts must be provided with baffles conducting the air. Sizes and the resistance of air grilles must be requested from the manufacturer.

4.4 Examples of industrial installations An installation with warm air blowing into two or more spaces must provide for the used air to return to the heater. A heater that is installed in a separate space with ducts connected to a the adjacent room. A heater with fresh air supply and return connection. The fresh air to indoor air ratio can be linked and adjusted by hand or by means of a stepped control and servo motor. The return and/or outside air can be potentially filtered. Annex to Instructions TR Centrifugal Version GB 139d Page 10/41

5 Electrical Connection 5.1 General The installation must comply with the local and/or national regulations. Ensure that it is connected to the correct consumer group protected by a MCB / RCD or main fuse. The wiring diagram for the appliance can be found at the end this manual (chapter 7). Isolating switch or plug The appliance must be equipped with a 2-400 Volt isolating switch which interrupts the phase(s) and the neutral (but not the earth connection). This isolating switch must have a contact gap of at least 3 millimeters. If the appliance is provided with a plug for use in a wall socket, the wall socket must be within reach at all times. NEVER interrupt the power supply to the appliance with other switches. This could lead to overheating of the appliance. 5.2 2Vac Version The supply is 2Vac. (50Hz) with earth connection. 2V Version with ventilator motor and external thermal safety device. This appliance employs Electrical diagram 7.1. The thermal safety feature in the current supply to the motor will trip when this motor is under excess load and the entire appliance will cease operation including burner and ventilator. The control of the appliance will also cease to operate and the thermostat control will not show a display. When the thermal fuse has cooled down the thermostat can be switched on again and the current will start the controls. 5.3 3-Phase 400Vac Version The supply is 3 x 400Vac (50Hz) with Neutral and Earth Neutral is also required for the smooth running of the appliance controls. After connecting the appliance, the direction of rotation of the ventilator must first be checked. If this is incorrect, the 2 phases must be changed round in the supply to the appliance. The ventilator has a thermal safety device in the current supply to the motor. This appliance employs Electrical diagram 7.2. The thermal fuse in the current supply to the motor will trip when thr motor is under overload and the entire appliance will cease operation including the burner and ventilator. The control of the appliance will also stop and the thermostat will not show a display. When the thermal fuse has cooled down, the power can be switched back on again and the unit will start. The TR heaters with a centrifugal ventilator from 2,2 kw motor power capacity is standard provided with a soft starter (Electrical diagram 7.3). For versions with the centrifugal motor power capacity smaller then 2,2 kw the soft starter is optional. Annex to Instructions TR Centrifugal Version GB 139d Page 11/41

6 Adjusting the ventilator In order to prevent overload of the electric motor, the ventilator has been set to a certain speed in the factory that is correct for the static pressure to be delivered by the appliance. This pressure is printed on the type plate. A feature of these ventilators is that increased air displacement also demands more amps to the motor. If the resistance of the air in the system is in practice lower than the static pressure setting of the air heater, the displacement of air in the ventilator will increase. This could lead to overload of the ventilator motor and hence to the appliance tripping out. Check the amperage of the ventilator motor. This needs to be lower than the maximum amperage printed on the type plate of the electric motor and/or the Technical Data. Always check the direction of rotation of 3-phase motors! 6.1 Excess amperage, too much air displacement When the amperage is too high the ventilator speed must be reduced or the static pressure must be increased. The speed of the motor is not adjustable in three-phase current. In that case resistance in the ducting system should be increased by means of a choke or a reducing valve, which in turn will displace less air and reduce the amperage. Refer to the table with Technical Data. Reducing the revolutions can only be done by changing the pulley and V-belts. Also check this with an amp meter and an air reading if possible. The air speed will increase proportionally when ducts have to be used that are narrower than shown in the table. The resistance will increase by the root mean square. For example: Speed 1.2 x higher Resistance 1.2 x 1.2 = 1.44 higher Important! If an air heater is intended to be connected to a duct system with a high static pressure this must not under any circumstances be implemented with unrestricted air diffusion without taking further measures. This will inevitably lead to the electric motor cutting out. Refer to the Technical data for the maximum air displacement, the static air capacity and the maximum amperage of the ventilator motor. 6.2 Insufficient air displacement The appliance will not displace a sufficient amount of air when the resistance in the system is too high. This is not a problem for the ventilator but the heat exchanger in the appliance can become too hot and will cut out because of overheating. In that case the resistance in the system must be reduced or the ventilator must run at higher revolution speeds. This can influence the choice of motor. Always contact the manufacturer in cases like these. Annex to Instructions TR Centrifugal Version GB 139d Page 12/41
