Recommendations about wiring of heating system of «Teplofon»

Electric heaters of «Teplofon» are issued two types: ceiling (power 300, 400, 500 W) and wall (power 300, 700 W).

The 300 W ceiling electric heaters are recommended to be used in rooms with low ceilings to 2,6 m. Can directly be placed over a workplace. Temperature of the heatgiving surface is 110 °C. The 400 W electric heaters are used for heating of rooms with ceilings up to 3 m high. Temperature of the heatgiving surface of 120 °C. 500 W electric heaters are recommended to be used over an entrance, window openings and also for rooms with height of ceilings from 3 m. Temperature of the heatgiving surface of 130 °C.

Wall electric heaters are established on «cold walls», mainly under windows. The recommended height of installation of 80-100 mm from a device bottom, the size to the shelf or a subwindow board over the device not less than 100 mm.

For creation of necessary temperature condition with heaters of «Teplofon» is recommended to use central temperature regulator that connect group of heaters. Temperature regulator is established on «a warm wall» at the height of 1,5 m from a floor. Avoid installation in zones with stagnant air, near doors, windows, heat sources. When using a temperature regulator on 16A (3,5 kW), about 4 700 W electric devices (2,8 kW) are recommended to unite in group. In need of association of bigger number of devices, on one temperature regulator, the contactor power corresponding to the power of the installed equipment is used.

On the heating system is installed separate switchboard with or without electricity. Switchboard selected according to the number of circuit breakers (feeders), with the installation of a backup machine zero and the grounding bus (no bridge between them). Connecting switchboard heating is carried out five-wire copper cable, wire diameter, picks up the load.

Automatic switches are recommended for use by Siemens. Selection is carried out on the load. On entering the set 4-pole differential circuit breaker.

Cable networks are laid copper cables in the required size. In child care used cable channels with only double lock. In the joints caps channels additionally installed clamps, mounting height of the cable channel from the floor (or ceiling) is determined on site (agreed with the customer). When wiring ceiling electric heaters, cable networks are laid on the suspended ceiling in the corrugated pipe.

Connecting Teplofon only through junction boxes with the use of permanent joints (welding, soldering), with mandatory tinned stranded (flexible) lived. If the electric heater cord length of more than 250 mm, the installation is in a corrugated tube with a diameter of 10 mm with fastening clips (clips).

Automatic switches and section of a cable for a single-phase network are given in the table:
