and on the same level as LST/MC treatment tank.
Make sure tank is accessible for refilling. Secure salt
feed tank (Fig. #1).
PLUMBING
1. Drain and empty treatment tank for an existing
system. If new system, perform following steps
before installing treatment tank.
2. Drill a 3/8" hole in treatment tank lid (Fig. #2).
3. Glue tank lid adapter (#31-325) in 3/8" hole
drilled in treatment tank lid using PVC cement
per PVC cement instructions.
4. Remove lid from salt feed tank by pulling sides of
lid up.
5. Remove packaging insert and unwrap salt feed
pump.
6. Place salt feed pump in hole at the end of mounting
adapter located at the bottom of salt feed tank
(Fig. #5).
7. Install tubing from salt feed tank to check Valve
and to fitting on the Lectra/San treatment tank
lid. Be sure arrow on check valve points toward
the Lectra/San treatment tank (Fig. #3).
8. Install overflow hose to bilge.
9. Connect pressurized freshwater with a shutoff
valve to the barbed nipple at the bottom of the
tank (Fig. #3).
10. Turn on water and check for leaks.
11. Fill tank with solar salt.
WIRING
WARNING: Hazard of Electrical Shock.
Disconnect Power at source before proceeding.
1. Remove control module cover (#31-460) from
treatment tank.
2. Install heat sink (#EHST0220) on transistor (Q7)
located on the circuit board (Fig. #4), making
sure that the heat sink is not contacting any other
component. The heat sink fits in only one position.
IMPORTANT:
A. Do Not use excessive force when installing the
Heat Sink.
B. Some components of the circuit board are
sensitive to static discharge. Proceed using
care and observing antistatic precautions such
as grounding straps on wrist and touching
ground frequently to discharge body static.
3. Connect salt feed pump cable to LST/MC circuit
board (Fig. #4). Connect red wire to terminal
U14 and black wire to terminal U15.
4. Replace control module cover and reconnect
electrical power.
