Warning
To Prevent Stack Damage
WARRANTY MAY BE VOIDED IF THE FOLLOWING PRECAUTIONS ARE NOT FOLLOWED!
Blockage or interruption of flow will damage stacks. If stacks are powered electrically
without the flow of water through any channels, they will be irreversibly damaged in 1-3 minutes.
Systems with an open system between the RO and E-Cell (ex. tank, decarbonator) must be fitted
with filters immediately preceding the E-Cell, to protect the E-Cell against contamination with
particulate matter! Generally, a 5um absolute or 1um nominal filter will be acceptable. For your
specific system requirements, consult your E-Cell System Integrator.
Common causes of blockage:
• PVC shavings, cement, or other debris from pipe work flushed into stack inlets.
• Slime or debris from a tank not filtered before going into E-Cell.
• Improper set points on flow switches or transmitters, or malfunctioning / disabled flow meters.
• Accidental closing of manual valves.
BEFORE APPLYING ELECTRICITY OR WATER TO THE E-CELL:
•
Flush piping thoroughly with filtered water to drain before connecting feed water piping
to the E-Cell Stacks™. Failure to flush the pipes to remove debris may cause irreversible damage to the
stacks.
• Pressurize stacks slowly over 1-2 minutes to avoid severe damage from water hammer. Do
not over pressurize stacks.
•
Ensure 4 flows have been established and all safety interlocks have been proven: Electrode
Outlet flow, Dilute Product Outlet flow, Concentrate Inlet flow, and Concentrate Bleed flow.
•
Verify that no chlorine or oxidizing agent enters the E-Cell Stacks™. Water must
meet feed specifications.
•
Operation at >0.5ppm hardness (as CaCO
3
) or >0.5ppm silica or failure to meet any
feed specifications can damage the E-Cell Stacks™ unless special precautions are being taken. Regular acid
cleaning, and RO permeate softening may be required.
•
For systems with a brine pump, the quality of the salt must be carefully
checked.
The salt must be of the special type listed in the E-Cell Owner’s Manual, otherwise the stacks can
be irreversibly damaged if run for extended period.
•
Plastic fittings and nozzles are not repairable. Handle with care.
