• Connect the control circuit power cord to 115 VAC, 60 Hz, or 230 VAC, 50 Hz, single-
phase power.
• Connect the magnetic motor starter 230/460 VAC or 220/380 VAC, three-phase
power to match the motor voltage and phase. Check the tag (located on the motor
starter) that indicates the factory wiring. A separate, fused disconnect for the motor
wiring is required, with proper protection for the Hp and amp draw of the motor.

3. PREPARATION AND START-UP

3.1. Pretreatment for Water Purification

All systems will operate most efficiently on filtered water with a pH of less than 6.5
and a Silt Density Index (SDI) of 3 or below. If the machine is operated on higher pH
water, other forms of pretreatment may be necessary. A water analysis prior to start-
up of the machine is required. To minimize the chances of calcium carbonate,
calcium sulfate, or other salt precipitation on the membrane, GE Water & Process
Technologies evaluates each application and water condition and makes specific
recommendations to ensure continuity of the membrane membrane warranty. Data
from the water analysis is processed with a computer program analysis to determine
if potential problems exist. If the machine is to be run at a different location than was
originally intended, a new water analysis is required for warranty consideration and
should be sent to GE Water & Process Technologies for review and recommendations
for operation of the machine.
Before entering the machine, the feed water must be filtered to 1 microns.
TLC membrane feed water must not contain the following chemicals or permanent
loss of rejection and/or permeate flow may result:
• Free chlorine
• Formalin (until after a membrane has been run for 24 hours; thereafter, 0.5%-
formaldehyde may be used as a biocide)
• Iodine compounds
• Quaternary germicides
• Cationic surfactants
• Detergents containing non-ionic surfactants
• Cleaners not approved by GE Water & Process Technologies
CAUTION: A water softener should not regenerate while the machine is running
unless safeguards are used to be sure the machine is operated on softened water
during regeneration.
