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 55 HT 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: 2,5mm2 in this case;
3.
Choose which type of wire you wish to use: type FROR 450/750V 5G2,5 (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 12,4 mm
5.
Identify the strain relief, according to TAB 3: for 12,4 diameter wire you could choose among strain relief with different threads: M20,
PG16 and GAS 5/8”. We choose PG16;
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 16, hole diameter is 23 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
♦
This product does not require any special maintenance.
♦
If the product requires repairing, contact an authorised technical service centre.
