passed through the wall opening. (Page 7)
Route the wires to their connecting points before securing the Control Unit in place. The control cable will be connected to the Treatment Unit, The main (+) power wire is connected and secured to the (+) terminal of a 60 amp circuit breaker or 50-60 amp fuse in the boat's power supply box. Be sure to route the wires away from all moving engine parts.
e) Check the alignment of all wires in the Control box. Make sure all wires are attached to the proper terminals and lugs and all screws and nuts are tightened.
f) Complete the installation of the Control Unit.
Wall Mounted
Reassemble the component-containing (front) half of the Control box to the wall-mounted (back) of the box. Secure the two parts of the box with the four supplied screws. Reduce any slack by pushing the wires through the holes in the wall.
Flush Mounted
Reassemble the two sections of the Control box. Place the mounting brackets on the Control box and secure the two sections of the box together and the brackets to the box with the supplied screws. Replace the Control Unit in the wall opening. Secure the Unit in place by screwing the mounting brackets to the wall. Put the faceplate onto the front of the Control Unit and secure it in place with the supplied screws.
2. Treatment Unit
a) Connect the control cable to the terminal block on the Treatment Unit. See Figure 6 Attach and secure the white wire to terminal A on the Treatment Unit terminal block. Attach and secure the red wire to terminal B, the blue wire to terminal C, and the black wire to terminal D. Remove the cable clamp located on the Treatment Unit cover. Slip the cable clamp over the 4-conductor control cable and re-secure the cable clamp in place on the Treatment Unit cover.
b) Connect the main ground (-) wire between the Treatment Unit and the main ground connection according to the following instructions.
Cut a length of wire long enough to connect between the Treatment Unit and the main ground connection for (-) power. Use #6-1 wire if length of wire needed is ten (10) feet or less, (#4-l if length is 10-25 feet long, or #2-1 if longer than 25 feet). One gauge lighter for 24V & 32V systems. Bare the ends of the #6 (or #4 or #2) wire and crimp a solder-less ring connector for a 1/4" stud onto one end. Attach the prepared end of the wire with a ring connector to the (-) electrode stud on top of the Treatment Unit, Tighten the nut onto the stud. There will now be four (4) wires connected to the stud.
Prepare the free end of the #6 (or #4 or #2) wire for connection to boat's main ground (-) connection. After the wire has been prepared, attach and secure it to the main ground (-) connection of the boat
c) Be certain to check polarity Lug E on the relay in the Control Unit is positive (+); lug D is negative (-). Units damaged by reversed polarity are not covered by warranty.
d) Check routing of all wires and secure wiring to boat structure as required by good marine practice.
3. Battery Power
During the treatment cycle (both motors and electrode pack in operation) the 12 and 24 V D.C. LECTRA/SAN units will draw 46 to 50 amperes of current for the two minute duration of the cycle. This amounts to about 1% ampere hours drain on the battery. (An ampere hour is a drain of one ampere for one hour) The 32 VDC LECTRA/SAN requires one ampere hour. The motors and the electrode pack are independently fused. Any excessive current draw can be checked at the terminals in the control unit A. B. & C Circuit breaker or fuse total load ratings are stated above. The lowest permissible Voltage as measured at the electrode terminals while the treatment unit is in the treatment cycle is as follows: nominal 12 V systems 11.5 VDC, 24 V systems 23 VDC; and 32 V systems 31 VDC.
NOTE: If a single engine boat has a 50 ampere alternator,
each two minutes that the engine runs offsets the
current consumed by one flush of the LECTRA/SAN. (Continued on page 222)
