Making The Electrical Connections
WARNING: This appliance must be earthed
1. The electrical connections are on the right hand side of
the unit.
2. The Baxi Solo 30 HE
A
is factory set to give a maximum
output of 22.0 kW. The Control PCB jumper positions are
as follows:
CN11 (Blue)
CN12 (Red)
If the installation requires a greater output to achieve the
desired room temperature, this can be increased to
30.18 kW and the boiler can be adjusted as follows (Fig. 32):
a) Remove the top right hand securing screw and
hinge down the PCB housing.
b)
Remove the Red jumper labelled CN12 from the
bottom left hand side of the PCB.
c)
Hinge back up the PCB housing and secure with
screw.
4. Route the incoming electrical cable/s through the
grommet in the support bracket. This will prevent damage
to the cable.
5. Lay the cable through the cable clamp to gauge the length
of cable required when it is connected to the 4-way
terminal block.
6. Connect the (S/L), (N) and ( ) wires to the
4-way terminal block (Fig. 33) and refit the cable clamp
(Fig. 31).
7. Check the electrical installation for;
earth continuity, short circuits, resistance to earth, correct
polarity and fuse failure.
