1. First-time installation
The following steps must be followed for new installations:
1.1.
Ensure that the equipment is totally disconnected from the mains power supply
1.2.
Empty the tank if it is full.
1.3.
Mount the electric element on the side mouth of the tank, following the steps indicated below:
1.3.1.
Dismount the side mouth panel, remove screws and nuts, counter-flange, stainless steel disc (in the case of
GEISER tanks) and seal, supplied with the tank.
1.3.2.
Place the new seal (3), element (2) and flange (1) in position.
1.3.3.
With GEISER tanks (side mouth with loose flange with 8 M8 screwed holes, mount screws (5), studs (6), washers
(4) and nuts (7) in the position indicated in fig. 1. Minimum torque 15 N·m.
1.3.4.
With CORAL VITRO tanks (side mouth with welded flange with 6 elongated holes), mount the nylon bushings (8)
in the counter-flange bore holes as well as the nylon washers (9) and metallic (10), according to the figure 2 to prevent
problems of galvanic corrosion. Minimum torque 15 N·m.
1.3.5.
Element wiring:
1.3.5.1. RB-25 (~230v) Element :
Carry out wiring layout according to fig. 3 and 7 (230v connection):
1.3.5.1.a.
CORAL VITRO tanks: Dismount the control panel and remove the earth wire that joins the panel to the
top flange on the tank. Mount the double wire supplied (15), with the following terminals:
- CSA insulated point terminal: connect to the control panel in the place where previously the earth wire was
connected.
- M 10 closed spade terminal: connect it to the top flange on the tank, in the place where previously the earth
wire was connected
- M6 closed spade terminal: pass the wire through the inside of the tube that connects the top part (control panel)
with the bottom part (side mouth) of the tank. Connect it to the elements M6 screwed stud and fix it in place using
one of the M6 nuts supplied (12).
1.3.5.1.b.
GEISER INOX tanks: Dismount the control panel.
For all tanks type connect the element wires (16), to terminals 6 and 7 of the control panel, as shows in to figure 7.
1.3.5.2.
RB-25 (3~400v) Element:
Carry out wiring layout according to fig. 4 and 8 (3~400v). Proceed in the same
way that elements RB-50, RB-75 and RB-100.
1.3.5.3.
Elements RB-50, RB-75 and RB-100:
Carry out wiring layout according to fig. 5 (one-stage connection) or
according to fig. 6 (two-stage connection, wires for this connection not supplied in the kit). If the element has been
factory mounting will be carried out according to fig. 5 (one-stage connection).
Mounting of these elements should be carried out using an external contactor (Not supplied ), as indicated in fig. 8.
To connect the double electrical connection, from one part to the terminals L, N and earth, the other part to the terminals
6 and 7 of the panel of control and, finally, to the terminals 4, 5 and earth (for connection of an auxiliary element), as
shows to figure 8.
ATTENTION:
It is important to tighten terminals by holding the bottom part of the terminal with a spanner
to stop it from turning round and round since this may damage the seal on the element.
Incorrectly tightened connections can cause overheating and the risk of fire.
Check that the connections are properly tightened before switching on the storage tank!
1.3.6.
Position the metal protective casing (11) and conect it with the wire (18) over the element that has already been
mounted and fix it in place using the M6 screwed stud and M6 supplied (12). Fix the metal casing with the M6 screwed
stud and M6 (12).
1.3.7.
Mount the side mouth panel (13) on the assembly and fix it in place using the 4 M4 screws (14). In case of
connections 3~400v, take out the double electrical connection between the resistance and the external contactor from
the hole of panel side port supplied, previous installation of the cable socket / Cable inlet.
1.4.
Adjustment and control
1.4.1.
Control on tank itself, Fig, 6: LAPESA storage tanks are supplied with a control panel which cannot be used for
the control of the electric element and consequently it must be replaced with another panel that has all of the safety and
control devices required for the operation of the electric element. These panels may be:
- K type control panel for GEISER tanks.
- TD type control panel for CORAL VITRO tanks.
In the summer position, the panel controls the electric element
In the winter position
,
the panel controls another device (e.g.: pump, 3-way valve, etc.)
ATTENTION:
All of these panels are dimensioned to work with 230v and therefore the electric connections
3~400v should be directly connected to an external contactor, dimensioned in relation to the power of the
electric element whose coil is to be controlled by the K or TD control panel, as appropiate. The contactor
must comply with the UNE-EN 60947 standard.
