MAINTENANCE OF COMPONENTS
PUMPS
1. Refer to pump section in this manual for your model of equipment.
2. Change pump oil after the first 25 hours of use. Subsequent changes should be every 250
hours or 3 months, whichever comes first.
A. Disconnect power supply.
B. Remove drain plug on pump and drain oil.
C. If the oil has water in it, it is important to flush out the pump with oil before refilling
pump with the proper oil.
3. Refilling: Replace drain plug and fill slowly to the dot in the center of sight glass, or the proper
level on dip stick. Do not over fill.
4. Use high quality 30 wt. non-detergent oil.
OIL BURNERS
1. BLOWER FAN: Clean blower fan in burner housing once a year or as often as needed. Dirt and
deposits will reduce air delivery and affect combustion.
2. FUEL NOZZLE: Keep tip free of surface deposits wiping with a clean, solvent saturated, cloth rag.
The nozzle should be changed once a year for maximum heating and emission control.
3. FUEL FILTER: Clean or replace every 400 hours or 3 months, whichever comes first (or as
needed). This will help prolong fuel pump life and burner efficiency.
DESCRIPTION
Racor Water Separator
4. FUEL TANK: Drain one pint of fuel from bottom of fuel tank every 50 hours of use or every two
weeks, whichever comes first. Check for water or contaminates in fuel. If any are present, drain
and flush fuel tank then refill with clean fuel. This will prolong fuel pump life and burner efficiency.
5. ELECTRODES: Clean off carbon deposits on electrodes. To adjust electrodes refer to figure and
these instructions:
A. TO REMOVE THE GUN ASSEMBLY: Disconnect the oil
line at the burner fan housing. Remove gun holding nut
on outside of housing. Loosen transformer hold-down
screw and swing open transformer on hinges. Gun
assembly can now be removed by turning 1/4 turn and
lifting out and pulling down through this opening.
B. SPACING OF ELECTRODES: The electrodes should be
spaced 1/8 inch apart, 5/16 inch above the top of fuel
nozzle and 1/4 inch from the center of fuel nozzle tip, to the electrodes.
