Start-Up
A. Before starting the spray pump, ensure that it is completely full of water.
B. Start the pump motor and make a visual inspection of the pump and piping for leaks.
C. Check the pressure gauge in the discharge line pump.
D. Check the voltage and amperage per the motor data plate.
E. If the pump surges: shut off the pump, verify the operating level in basin is within range, after the system
has equalized.
F. Close the water make-up valve, and adjust the oat valve to a higher setting. Repeat steps A and B.
G. If there are more than one pump, start remaining pumps one at a time by repeating steps “B.2.
CONTROLLING WATER LEVEL”.
H. If the basin overows, close the water make-up valve, lower the oat valve setting, and repeat (“B.2.
CONTROLLING WATER LEVEL”). In case of experiencing problems with the pump(s), refer to pump’s IOM
manual.
I. Shut off pump(s) if required.
B.4. GEAR REDUCER
A. Check all ttings on the gear reducer to ensure that there are no visible leaks.
B. Make sure that the gear reducer is lled with the proper amount and type of lubricant.
C. The initial oil level should be to the middle of the oil level sight gauge and should be maintained so that
the oil level is always visible in the sight gauge window when the unit is stationary, level, and the oil is at
ambient temperature.
D. If shimming is required, take precautions to prevent distortion of the housing. Align driver and gear
reducer to obtain parallel and angular alignment. Recheck alignment after two weeks of operation.
E. For VFD see section “C.1 FAN CONTROL - VFD“.
F. For gear reducer maintenance refer to section “D.5 GEAR REDUCER”.
When using a variable frequency drive (VFD), do not operate gear drive below 450 RPM fan
motor speed.
CAUTION
▪ The original oil should be replaced after 500 hours of operation or four weeks,
whichever comes rst.
▪ After the initial oils change, oils should be changed every 2500 hours or every six months,
whichever comes rst.
CAUTION
B.3. SPRAY PUMP
▪ Refer to pump’s IOM manual to ensure pump proper installation, operation and start-up.
▪ Do not run the pump(s) dry or when the suction is not full of water; damage may occur.
▪ Do not start pump(s) with the valve fully-open; there is risk of overowing the Closed Circuit
Fluid Cooler.
CAUTION
