ELECTRIC HEATERS TC8 Installation Instructions

1 TRI HATRS T8 Installation Instructions T8II 1/V.2 TRI AIR HATRS PT WITH TRS Unpack the heater taking care to ensure items and paperwork are removed from the centre of the heater duct. The terminal box may also contain wiring instructions. If you are only installing the heater in the air duct, leave these instructions for the electrician! The heater can be installed the duct run, with either horizontal or vertical flow. With vertical ducts consideration must be given to items in the run above the heater which could be damaged by heat rising when the fan is switched off. All heaters should be kept away from plastic conduits or materials easily damaged by heat. Allow for casing temperature of 100 (ideal minimum air velocity = 2m/s). These heaters must not be installed outside unprotected or in areas that are washed down! o not use flexible connectors directly onto the heater. The best position for the terminal box is on the side of a horizontal duct. nsure access to the terminal box is possible! ake sure lagging etc. does not cover the terminal box. A TFS2 combined temperature and airflow sensor is supplied as standard. This will be found attached to the heater on a coiled lead. This should be mounted in the duct 1 to 2m downstream from the heater where the sensor cannot be damaged by heat. A 25mm holesaw and 2 PK fixing screws will be required. IPRTAT The TFS2 has an Airflow direction label attached and will only operate if installed in the correct attitude. WIRI All wiring must be carried out by a qualified electrician in compliance with the latest regulations. These units are internally pre-wired and require only a suitable supply feed connection to operate (see rating label). If the option to feed the fans is not used and the supply fan is not local to the heater, it is possible to use only the sensed airflow to switch on the heater. The output air temperature will be as set on the face of the panel. If you need to switch the heater off from a remote time clock, remove the link provided and wire from the clock. The controller has two 1ph fan outputs (.5A max) which, if used, run the fan on for 2 minutes after the time clock switches off the heater. ther features are available, please refer to T8 wiring instructions. ote; take care when using remote fan speed controllers not to let the air velocity drop too low. Also try to avoid using the controller to switch the system off as this can lead to nuisance tripping of the high temperature cutout in the heater. SAFTY very system should have an isolator switch which can be locked in the off position to prevent accidental reconnection during maintenance. When resetting the thermal cutout the heater may suddenly switch on and element terminals etc. will become live. nsure the heater is correctly earth bonded. Terminal covers must be secured after inspection and should be labelled IST SUPPY BFR RVI THIS VR. It is the installer s responsibility to ensure the installation meets all current Health & Safety Regulations.

3 T8 Thyristor Temperature ontroller T8/1-10/V. Specifically designed to mount onto a eatafan electric air heater, either duct mounted or built into an Air Handling Unit. The T8 unit acts as a thyristor temperature control panel to control a 220/250V single phase 2 step heater up to 2 X 19A (9.0kW) with an additional relay and has 5A fused outputs for single phase supply and extract fans up to a maximum of.5a each. Although the unit has been designed primarily for single phase heater loads up to 9.0kW, it has a SSR (Solid State Relay) output which can be used to control larger three phase (80/0V) heater loads up to 2.0kW.

5 R1 (T & T8) Remote ontrol Unit R1/07-10/V.5 The R1 is designed as a remote control unit to work in conjunction with eatafan control systems and can be flush or surface mounted using the same fixing dimensions as a standard 2 gang electrical switch box. An on-off switch is incorporated so that the user can turn off the system, allowing the timer to cool the elements. The temperature adjustment feature is designed to give an adjustment of or + of the pre-set temperature on the main temperature controller, i.e. if the main controller is set to 20, the R unit will adjust between a minimum of 16 and a maximum of 2. With the control knob adjusted to the midpoint on the dial the preset temperature will be achieved. A duct temperature sensor is provided within the TFS2 with eatafan T & T8 control systems, however this can be replaced with the room temperature sensor provided in the R1 using the R1 room sensor adaptor lead (enclosed). Wiring: Four cores of 0.75mm² cable are ideal and can be run for 20m without difficulty. o not, however use fine data type cables.
