Evaporative Cooling - Greenheck IGX Installation, Operation And Maintenance Manual

Maintenance Instructions:
Optional Evaporative Cooling
Regularly scheduled maintenance is the key to peak
performance, minimized cost, and extended life of the
evaporative cooler. The following is a checklist of
items that need to be looked at on a regular basis.
1. The media should be checked for mineral and
foreign material deposits that have built up. If these
items are left on the media, the life and performance
of the unit will be greatly reduced. Also, there are
risks of water carry over when this type of condition
exists. When signs of mineral build-up are noticed,
you should increase the bleed off rate. If this does
not solve the problem, chemicals may need to be
added to the water. The evaporative pads tend to
be self cleaning. Depending on water quality and
system maintenance, the useful life of the pads
should be 3 to 5 years minimum.
2. The media should be periodically brushed lightly
with a soft bristle brush in an up and down motion
while flushing with water (never brush side-to-side).
This will aid in reducing the amount of foreign
material build-up.
3. The water should be shut off and all the lines
drained when the temperature drops below 50°F.
4. When the evaporative cooler is going to be used for
the first time each season, it is recommended that
the media be flushed with clean water for a period
of 20 minutes.
5. At the beginning of each cooling season, the upright
recirculating pump should have the shaft oiled and
spun to eliminate the potential of seizing and pump
burn out.
6. If the cooling media was removed from the unit,
check to make sure that is is not installed
backwards. If the media is installed backwards,
there will be large amounts of water carry over
downstream of the evaporative cooler. Continuous
operation in this manner may cause serious damage
and void the warranty.
7. At the end of each cooling season the evaporative
cooler should be thoroughly cleaned. Use the
following guide for annual cleaning:
• Disconnect power to unit.
• Shut off all water to the unit
• Open evaporative cooling section door
• Clean all interior parts of any mineral deposits of
foreign materials that may have built up during
the cooling season
• Replace all worn or non-functioning parts
• Reassemble the cooling unit.
• Replace cooling section door.
