CONVERSION OF LECTRA/SAN TO LECTRA/SAN EC INSTALLATION INSTRUCTIONS
Figure #11C
Parts included in package:
Control Module (32-402, 33-402 or 34-402) - Mounts
directly to treatment unit
Control Cover (31-460) - Installs over Control Module
Control Indicator Panel (31-403) - Replaces old
Control unit
Ribbon Cable (31-404) - Connects Control Module To
Control Indicator Panel - 12' long.
Tools needed - 3/8", 5/16", and 7/16" nut drivers, blade

INSTALLATION
Before beginning conversion disconnect battery leads
and be sure power to unit is OFF.
If old control unit was flush mounted you will need to
cover the opening. If the new control indicator panel will
be located in the same opening see the panel template for
cutout purposes.
A. Existing Control Unit - Remove and discard existing
Control Unit (32-2000, 33-2000 or 34-2000) and Control
Cable (31-210), reroute positive (+) wire from terminal E
on the relay to the Treatment Tank. Connection will be
made during Step 9.
B. Treatment Tank
1. Remove terminal block (31-131), save screws, nuts
and washers for mounting Control Module in Step 5.
Discard terminal block (see Fig. #11C). Disconnect
negative battery wire to electrode pack.
2. Remove mounting straps. They will need to be routed
through the slots on new Control Module (Fig. #12B).
3. Remove two screws from lid as shown in Fig. #12B
and reinstall them in place of the screws removed in
Step 1. The two holes left by removing the screws will
be used for attaching the Control Module in Step 5.
4. Connect RED (+) and BLACK (-) wires from new
Control Module to POSITIVE (+) and NEGATIVE
(-) lugs on cover (Electrode Pack). Polarity must be
the same (see Fig. #13B).
5. Mount Control Module (32-402, 33-402 or 34-402)
using the screws from Step 1.
6. Cut the BLACK NEGATIVE (-) wire terminals off
both the mixer and macerator motors. Strip 3/8" of
wire and attach to crimp connectors on the black leads
from Control Module (see Fig. #13B).
7. Cut the POSITIVE (+) wire terminal off the macerator
(larger) motor and strip 3/8" of wire. Attach to
ORANGE POSITIVE (+) lead with crimp connector
from fuse block (see Fig. #13B).
8. Connect mixer (smaller) motor POSITIVE (+) lead to
Fuse A on fuse block using the existing terminal (see
Fig. #13B).
9. Connect POSITIVE (+) and NEGATIVE (-) wires to
the front side of Control Module (see Fig. #12B).
10.Reinstall mounting straps through slots on Control
Module and resecure them (Fig. #12B).
