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.

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.
