Product description
TEF 1058 thermostat is according to NORSOK requirements and is used for a various range of applications such
as hazardous areas, chemical and petrochemical industries, industrial plants (for frost protection or temperature
maintenance).
Transport and storage
•Transport and store the equipment only in the original packaging
•Store the equipment in a dry and vibration free place
•Do not drop!

Mounting and installation
DANGER
Incorrect mounting and installation may lead to explosion risks, risk of falling objects, risk for electric shock and
risk for equipment malfunction. In turn, this can lead to severe damage and/or injuries.
Mounting of wall mounted type (fig. 01)
•Mount the thermostat junction box by at least two Pcs. M6 bolts placed diagonally on a wall or proper
supported rack.
•Remove dust protection or stopping plugs and install selected gland. Use stopping plugs for unused
entries. Only certified cable glands and stopping plugs may be used. Select gland according to the cable
diameter used.
•Strap the transition unit to pipe with pipe straps.
•Assembly the flexible conduit according to the special gland. see fig. 02

Mounting of pipe mounted type (fig. 03)
•Mount the thermostat junction box either standing or hanging to pipe with pipe straps.
•Remove dust protection or stopping plugs and install selected gland. Install the drain plug at the lowest
point. Use stopping plugs for unused entries. Only certified cable glands and blinds may be used. Select
gland according to the cable diameter used.
Temperature sensor
The sensor must be strapped in good thermal contact with the pipe or equipment. In addition to general mechan-
ical protection, the sensor must be protected so that the thermal insulation cannot be tapped between the sensor
and the heated surface. The sensor is normally fixed to pipe or object by use of aluminum tape. Other methods
could be thermowells suitable for the application.
Note!
The widened area of the capillary tube, shall be clamped by the cable gland sealing ring. The sealing ring is not
dimensioned for the Ø1,5 mm capillary tube.
Termination
In order to maintain the mode of protection, connect the conductors with special care. The isolation must reach up
to the terminals and do not damage the conductor. Termination of heat cables must be according to cable
specification given by the supplier of these. Tighten all the terminals, also those vacant. Reinstall the lid and tight
bolts firmly with suitable tool by hand force. Over tightening may impair the protection category.

Setting the limit value in accordance with the scale:
Use the internal scale to set the limit value on the setpoint adjuster. (Do not exert mechanical pressure to the
setpoint value spindel).
Setting the limit value in accordance with installation specific operational
characteristic:
•Heat the temperature probe-in the unit- to the required limit temperature (temperature adjustment time at
least 5 minutes), recording and monitoring the exact temperature on the temperature probe with a
librated reference measuring device.
•Turn the setpoint adjuster from the scale limit value towards the scale start value, determine the required
switching point position (circuit opens and electrical circuit 1-4 is closed).
Maintenance and cleaning
•Maintenance according to national regulations and company practice.
•Before opening the junction box make sure that the power is disconnected.
•Servicing the junction box is done be checking the intactness of the junction box, gasket and glands. If
necessary lubricate the lid bolt threads with grease type Renolit Unitemp 2 from Fuchs.
•If repair or overhaul is necessary this may only be done with Tranberg spare parts.
•Modification of the JB or change of design are not permitted, except for installing additional glands and
terminals according to the approval of the JB.
•Clean only with a damp cloth, water and mild detergents. Avoid chemicals with high or low pH,
abrasives, high pressure washer, strong detergents, solvents, petroleum- or alcohol based cleaning
agents and similar. Avoid any corrosive media.
