Replace Pre-Filter

A more frequent schedule change-out
may be needed (Refer to Challenge Water
Recommendations on page 6)

RO membrane fouls (normal
conditions)

Replace RO membrane

Check for: 1. feedwater pressure, 2. production
flow rate, 3. drain flow rate before replacing RO
membrane

Ensure drain line is not kinked or plugged.
Replace if needed.

RO membrane fouls (high feed
water hardness/TDS)

Install RO add-on head and cartridge

Contact Dealer

Install a HFRO 33% Recovery Kit
Install water softener upstream

RO membrane fouls (high particle
load in incoming water)

Install prefilter and RO expansion heads and
cartridges

Interrupted feedwater supply

Press Reset button on top of electrical
enclosure

Reference system startup procedure

Water temperature below 50

Install RO expansion head and cartridge

Low feedwater pressure (below
30 psi)

Contact plumber to resolve problem

Reference system startup procedure once low feed
water problem is resolved

Iron or Manganese in incoming
water

Contact your dealer/distributor to install
specific iron or manganese reduction system

TDS of product water too low

Blend too low

Re-adjust blending valve to allow more
blending
