Trouble-shooting
PROBLEM / SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
The water is not falling
uniformly from the ll.
Clogged nozzle(s) Clean nozzles and replace as required.
Low pressure at the water inlet Check pressure at the inlet and adjust as necessary
(while pumps are running).
Obstructed ll media Inspect and perform cleaning and maintenance if
required (see section “D.2 BASIN” of this manual).
Water leaking around the
access door
Improperly installed or
damaged gasket
Ensure that the bolts attaching the access door are
all in place and are properly tightened. If leakage
does not stop it will be necessary to take the Tower
out of service to inspect or replace the gasket.
Water leaking from a
crack in the berglass
The Tower was not handled
properly during installation
or some other impact has
occurred
Call your local REYMSA Representative for advice.
Water leaking through the
air inlet louvers
High water operating level Adjust the water make-up valve to a lower operating
level.
System water is overowing
the Tower when pumps are
stopped
Check piping height, grade and check valve in pump
discharge.
Excessive water ow through
the Tower
The Tower should have been installed with a
water pressure gauge and throttling valve at the
water inlet. Check the pressure reading at the
Tower inlet and ensure that is does not exceed the
recommended pressure for each Tower. Use the
throttling valve to adjust the pressure. Closed Circuit
Fluid Coolers are designed to operate between
2 psi and 10 psi at the Tower inlet, REYMSA
recommends to work between 4-8 psi.
Damaged or reversed louvers Replace the louvers if damaged. Conrm that
louvers are installed properly, parts facing inward
and downward.
Excessive Drift
Excessive water ow through
the Tower
The Tower should have been installed with a water
pressure gauge and a throttling valve at the Tower
inlet. Check the pressure reading at the inlet and
ensure that it does not exceed recommendations. Use
the throttling valve to adjust the pressure.
Drift Eliminators are damaged,
are not lying at or improperly
aligned
Inspect the drift eliminators to ensure that there is no
damage, that they are lying at and that there are
no gaps between them.
Excessive accumulation of
debris or dirt in the bottom
of the basin
Unsatisfactory water treatment Remove the debris and dirt while the Tower is out of
service.
Excessive airborne
contamination
Consider ltration.
Unusual noise or vibration
in the Gear Reducer (HFC-F
Models)
Misalignment Stop operation of the tower. Make sure that gear
drive, drive shaft and motor are bolted and tighten
Torsional Vibrations
Unstable support Make sure the motor support is secured.
Coil incrustation
Unsatisfactory water
treatment.
Clean the inside coil as manufacturer recommends.
Coil leaks
Damaged coil. Find the leak and close the damaged line.
