EVAPORATIVE CONDENSER -
MAINTENANCE REQUIREMENTS
Pump Maintenance:
Cleaning - Remove oil, dust, water, and chemicals
from exterior of motor and pump. Keep motor air
inlet and outlet open. Blow out interior of open
motors with clean compressed air at low pressure.
Labeled Motors
- It is imperative for repair of a
motor with Underwriters’ Laboratories label that
original clearances be held; that all plugs, screws,
other hardware be fastened securely, and that parts
replacements be exact duplicates or approved
equals. Violation of any of the above invalidates
Underwriters’ Label.
Fan Motor Maintenance:
Same as pump maintenance
Access Doors:
If scale deposits or water is found around the
access doors, adjust door for tightness. Adjust as
necessary until leaking stops when door is closed.
Bearings - Lubrication:
Every 6 months or after a prolonged shut down.
Use waterproof, lithium based grease. Below 32°F
- Esso Exxon or Beacon 325. Above 32°F – Mobil
Mobilox EP2, Shell Alvania EP2 or Texaco RB2.
Required Monthly Inspection:
1.
Clean sump section interior. Dirt and other
impurities which have accumulated in the
sump must be removed from the sump area.
Shut off make-up water ball valve and open
the drain connection for flushing of the sump.
2.
Clean dirt out of sump using a water hose
(not a pressure washer).
3.
Clean sump suction strainer.
4.
Check water operating level. Adjust float
as required.
5.
Inspect fan motor(s) and water circulation
pump(s) and lubricate per the lubrication
nameplate
or
manufacture’s
recommendations.
6.
Inspect axial fans and eliminators
removing any debris which may have
accumulated during operation.
7.
Inspect the water distribution system to
insure that nozzles and spray orifices are
functioning correctly. The inspection must be
made with the circulation pump on and fans
off.
Mist Eliminators:
The mist eliminators must be correctly positioned
when they are replaced during cleaning or service.
Air Inlet:
Inspect the air inlet louvers and mist eliminators
into the condenser section on a monthly basis to
remove any paper, leaves or other debris that may
block the airflow.
Stainless Steel Base Pan:
The base pan under the tube bundles is stainless
steel and may sometimes become tarnished due to
contamination. Inspect these surfaces annually to
ensure they remain clean of any contamination
that may result in damage. Any surfaces that show
contamination must be cleaned ONLY with a
commercial stainless steel cleaner to restore the
initial appearance.
Propeller Fans and Motors:
The fans are directly mounted on the motor shafts
and the assemblies require minimal maintenance
except to assurance they are clear of dirt or debris
that would impede the airflow.
Required Annual Inspection:
In addition to the above maintenance activities, a
general inspection of the unit surface must be
completed at least once a year. Remove spray
header and flush out.
Cleaning:
Mechanical cleaning, including pressure washing,
must never be performed as surfaces and seals
could be damaged. Chemical cleaning that is safe
for stainless steel, copper, aluminum, ABS plastic
