4.
Open the connection box (fig. 3/a),drill it through the marked point (fig. 3/b) and fix the strain relief or the joint connector (fig
3/c-d). The diameter of the hole to drill on the connection box changes according to the dimension of either the strain relief
or the joint connector, and the hole must be drilled on the top side of the box exactly where the the point is marked.
5.
Make the necessary electric connections (fig 3/e-f) caring not to peel the conductor more than 8mm to avoid the risk of
contact between conductors. Do not screw the connection block on wires isolation sheath;
6.
Firmly tighten the strain relief or the joint connector (fig. 3/g)
7.
Lock the connection box with proper screws (fig 3/h)
♦
In case you have chose to use a power cable you must:
-
Choose a cable type H05RN-F or FROR 450/750V;
-
Identify the correct strain relief according to the diameter of the cable shown in TAB 3;
-
Always be aware that once the cable is connected, it won’t ever touch the steel parts of the product
Example:
You have purchased the Thermo version 55BT and you wish to use a power cable for a three-phase connection. Hence, you’ll have to:
1.
Identify the necessary number of conductors: you choose connection type “E” (three-phase), so you’ll get 5 conductors for
earth, neutral, L1, L2 and L3.
2.
Verify the minimum section diameter of the conductors as indicated in TAB 2: 1,0mm2 in this case;
3.
Choose which type of wire you wish to use: type FROR 450/750V 5G1 (yellow/green connector for earth) is necessary for
the required needs;
4.
Verify the exterior diameter of the wire by measuring or contacting the supplier: section of the wire in this case is 9,4 mm
5.
Identify the strain relief, according to TAB 3: for 9,4 diameter wire you could choose among strain relief with different threads:
M20, PG13,5 and GAS ½”. We choose PG13,5;
6.
Verify the hole diameter you will have to drill on the connection box according to the strain relief you wish to use, according
to TAB 3: for PG 13,5, hole diameter is 21 mm.
7.
Drill the connection box on the marked spot with a hole diameter according to the previous point (fig. 3/a-b);
8.
Fix the strain relief to the connection box with the right nut (fig. 3/c-d);
9.
Insert the cable through the strain relief and connect the power wires (fig. 3/e-f)
10. Tighten the strain relief (fig. 3/g)
11. Lock the connection box with 4 proper screws (fig. 3/h).
5. Using the product
♦
No on-off switch or temperature control devices are provided with the product, and switch on/off has to be regulated by special
devices to be included before the installation (es. leakage breaker or thermal magnetic switch).
♦
In versions with 2 or 3 heating resistances there is the possibility to realise independent power circuit to activate each single
heating element to respond to the demand of reduced heating power when requested. Especially in the 3 heating elements
version, we suggest to realise one power circuit just for the heating element in the middle (phase L2) and a different one for the
heating elements on the side (phase L1 and L3) to maximise, according to the real heating needs, 1/3, 2/3 or the whole product
power.
♦
Please mind: in the first hours after installation, the product could stink out the room where it has been installed. This is due to the
presence of small residua during the assembly process and does not represent a defect or a malfunction of the product or any
risk for the safety of end users.
6. Maintenance
