Servicing and Maintenance
This evaporative cooler must be installed, operated, and maintained by suitably qualified
personnel and in accordance with this manual.
CAUTION: Risk of electric shock. The electric supply of the evaporative cooler must be shut down.
Disconnect the power at the external breaker before commencing any maintenance work.
Preventative Maintenance
The SKVF requires regular periodic service to ensure efficient and trouble-free running. Generally, frequency of cleaning
can range from two months to once a year, depending on the following factors:
•
Quality of water
•
Frequency of automatic drain cycles
•
Demand placed on the evaporative cooler
All SKVF evaporative coolers are programmed for 1000 hours of operation. This is a default factory setting.
To view the number of hours the unit has run and the number of service hours, use the control panel to access the
Service
Menu (see page 33 for more details).
After 1000 hours of operation have passed, the Status Display LED on the control panel will turn red, indicating that the unit
is due for servicing. Although the SKVF will continue to operate, it is imperative that service is performed as soon as possible,
in order to ensure proper functionality.
Verification List
Perform the following activities regularly to ensure optimal performance and operation of the evaporative cooler.
•
Ensure that all electrical connections are secure.
•
Check drain operation and flow.
•
Check for water leaks.
•
Check for stagnant water or excessive water in floor pan.
•
Remove the media cassette(s) (see Removing the Evaporative Media section on page 47) and remove / clean
any residue or deposits accumulated on the media(s).
•
Check for any mineral deposit in the tank or on the media, which would indicate that the water quality is poor
and that the dilution ratio must be increased (see
DilutionRatio
setting in the
Installation
menu on page 34).
•
Check for any accumulation of dirt in the bottom of the tank and the floor pan. If there is presence of
impurities, clean the tank at the bottom of the unit.
•
Check the distribution pipe at the top of the media and ensure that the water distribution is even. Remove the
pipe and clean it if necessary.
•
Check the flow rate at the output of the pump and clean or replace it if necessary (only for SKVF-R models).
•
Ensure that the water supply and drain hoses at the bottom of the evaporative cooler are clean and in good
condition.
•
Ensure that the 5µm water pre-filter is not clogged.
•
Verify if the 5μm pre-filter and silver ion service warning has appeared (
WtrServiceDue
). If so, replace the
5μm pre-filter and silver ion dosing cartridges.
•
Observe the operation of the water flow and evaporation cycle.
