Installation and storage instruction

11

Installationl Plug immersion heaters may be used both in

vertical or horizontal position. Anyhow it is

necessary to lay them with the heated part

completely immersed.

This kind of heater is normally connected by

screwing – in case the machinery has a coupling

box with a matching thread-; however is also

possible to connect it by a separate hole and

fastened to it by a ring nut or grommet nut

In the presence of gasket please verify their

capacity to reach the max. working temperatu

re/pressure the device will reach.

If supplied with a thermostat please, connect it in

order to interrupt the feedings – and consequent

ly the heating- when the set temperature is rea

ched.

After using the heater at the working temperature

few hours please verify/check the tightening of

the threaded parts.

Temperature controllersl Temperature controllers have to

match the power consumption and

the used temperature.

Electric connection l Please, stick to the nameplate features (specially regarding

feeding voltage and power).

Please, use connection leads suitable for the environmentin

which they are used.

Operation l Security procedures for the the

handling of electrical items and

application must be followed

Do not touch the heater while in

use because it can get very hot

Please make sure that the hea

ting elements can not touch

flammable material while in use.

Storel Store at room temperature in a

dry place.

BewarelThis kind of heaters contains magnesium oxide –an insu

lating and highly hygroscopic material. That is why if laid

in a damp environment a bit long, the humidity tend to

accumulate / gather inside the heaters causing insulation

resistance decreasing with consequent intervention of

safety device.lIn case of long term storage is expedient before to use the

heaters to check the insulation resistance with an insulation

tester applying it between the phase and the earth: while

using a tension not less than 500V the revealed insulation

resistance value has to be equal or superior to 5 Megaohm.

In case the checked value is lower a drying up will be neces

sary putting the heaters in a oven at a temperature between

100° and 130°C till the insulation value will be restored (nor

mally about 10/12 hours).
