1.3 THE PRODUCT’S STRUCTURE AND OPERATION

1.3.1 General description

TEHs, placed inside the Product (see Figures 1 and 2), heat the air causing

natural convection within the heated spaces.

The Product is additionally equipped with:

1) capillary temperature controller (with adjustable threshold of actuation) TC-1,

which temporarily switches TEH off, once air temperature reaches the preset one;

2) temperature fuse (sensor-relay) ТF-1, which prevents the Product casing from

overheating by disconnecting TEH power circuit.

Х1 –terminal block to connect power supply network (127; 220; 380 V AC);

S1 –power breaker (switch); E1–E6 –TEHs

Figure 1 –Structural diagram of the Product, UT-S type

Note –TEHs E1–E2 are installed on UT-300S, UT-600S and UT-800S types,

E1–E4 –UT-1200S types, E1–E6 –UT-1800S type.

Х1 –terminal block to connect power supply network (127; 220; 380 V AC);

Е1–Е8 –TEHs; S1 –power breaker (switch)

Notes

1 TEHs E1–E8 are installed on UT-300C, UT-600C, UT-800C and UT-1200C

types, E1–E4 –to heaters UT-1800C type.

2 TEH power of UT-1800C type is higher than others, therefore number of

TEHs is smaller.

1.3.2 Controls and indication

The following controls and LEDs are located on the Product casing:

knob of temperature controller TC-1 (see 1, figures 3, 4) to set required air

heating temperature;

power piano type on/off switch (see 3, figures 3, 4) with an integrated LED

displaying Product operation.

Select an installation place providing free access, connection of cables and

termination of cable ends in accordance with the overall dimensions, see ANNEX А.

The Product should be mounted on a vertical bulkhead inside the ship.

Caution!

Install the Product only vertically in order to avoid cyclical transition to mode of

overheating protection and to ensure natural convection!

Install the Product vertically; the panel with control elements shall be on the

right-hand side.

When mounting, leave not less than 70 mm free space from the top and bottom

of the Product to ensure air circulation.

The Product UT-S type may be installed in spaces with increased humidity; the

Product shall be grounded.

Caution!

Do not install the Product in the strong draught, it may impede heating and

temperature control!

2.3.2 Installation of UT-C type

Install the Product on vertical surface according to drawings in Annex А. It is
