* The wire length is the total distance from the
©battery to the pump and back to the battery.
It is recommended to use a relay with a light
wire from main cable to switch to shorten the
main leaders.
Note: Before installation with electrical
control systems, check that equipment
to be used is of sufficient rated capacity
to accept amperage draw of motor. Low
voltage will cause motor to overheat.
Maintenance
The system shall be periodically
sanitized using the following procedure:
1. Fill the tank with a solution of
house hold bleach and
potable water – 1 ml (.03 oz.)
bleach/1 l (32 oz.) water.
2. Open all faucets and run until water
flowing smells of bleach.
3. Close all fauces.
4. Drain solution from tank.
5. Refill tank with potable water.
6. Open all faucets and run until
bleach has been purged.
