Troubleshooting - Hellenbrand Iron curtain system 2.0 Owner's Manual

Troubleshooting

Complaint
1. Iron or manganese* bleed-
through or staining
Sulphur odor bleed-through
*Manganese can be slow to oxidize when the pH is less than 8.5
6
Problem
A. Inadequate backwash of filter
B. Fails to regenerate
See specific control manual for
filter
C. Water contaminant levels are
greater than limits established by
the manufacturer
D. Inadequate aeration
E. Exceeding recommended filter
system flow rate
F. Regeneration during service flow
demand
G. Raw water bleeding through filter
See specific control manual
Cause
1. Plugged drain line flow control
2. Insufficient water supply from
well
3. Plugged aeration tank inlet dif-
fuser or pick-up tube
4. Media bed fouled
1. Interrupted electrical service
2. Faulty timer motor
3. Faulty skipper wheel (on Fleck
Control)
4. Faulty 24 hour gear
1. It is not uncommon for local
water conditions to change
1. Loss of air through inlet check
valve
2. Loss of air through air leak
3. Faulty aeration pump due to:
a. Electrical failure
b. Pneumatic failure
c. Damp environment
4. Air loss through high demand
1. Service flow rate demand is
higher than filter system design
flow rate
1. Time of day set incorrectly
Solution
1a. Clean or replace drain line flow con-
trol
2a. Check for minimum specified flow
and pressure requirements of filter
system
3a. (Generally will only plug with the
presence of iron bacteria) Clean aera-
tion assembly and shock treat the
water supply with chlorine as needed
to control iron bacteria
4a. Rebed filter and correct the cause of
fouling
1a. Assure continuous electrical supply
(check plug, breaker, fuses, etc.)
2a. Replace timer motor
3a. Replace skipper wheel
4a. Replace 24 hour gear or timer as-
sembly
1a. Consult dealer
1a. Check installation position of check
valve – Consult Installation and
Operation Manual for proper position
1b. Check for foreign material in seat
of check valve, clean or replace as
required
2a. Check aeration tank assembly for
any air leaks and repair (Note: soapy
water solution works well for locating
air leaks)
3a. Assure permanent electrical service
(check plug, breaker, fuses, terminal
block on control valve, etc.)
3b. Check for adequate pressure and
volume production from air pump.
Repair or replace air pump
3c. Clean, repair or replace aeration
pump, ventilate environment or pro-
vide external air source
4a. Increase air recharge frequency of
filter. See page 9
1a. Install a flow control at filter system
outlet equal to or less than the design
flow rate of filter system
1b. Install additional filter(s) or a larger
single filter system which meets both
the service flow demand and back-
wash flow requirements available
1a. Reset timer
1a. Assure all adapter base o-ring seals
are in place
