INSTALLATION & MAINTENANCE INSTRUCTIONS
ULC S602
 
It is the responsibility of the installer and tank owner to ensure that the following requirements are met. These are general installation instructions. For specific details and regulations, you must refer to the appropriate codes and local regulations.
 
1. THE INSTALLER SHALL ENSURE THAT ALL APPLICABLE FEDERAL, PROVINCIAL & LOCAL CODES ARE MET PRIOR TO TANK INSTALLATION.
2. CONSULT AUTHORITIES HAVING JURISDICTION BEFORE INSTALLATION.
3. MAXIMUM LEG HEIGHT OF 254MM.
4. FOR BOTTOM OUTLET TANKS, PITCH TANK TOWARDS DRAIN AT LEAST 10MM PER 500MM TO PREVENT WATER COLLECTION IN THE TANK.
5. TANK SUPPLIED WITH THREAD PROTECTORS ONLY, NOT LIQUID TIGHT CLOSURES.
6. OPEN SECONDARY CONTAINMENT TANKS TO BE USED INSIDE ONLY.
7. DOUBLE BOTTOM TANKS SHALL NOT VENT DOUBLE BOTTOM TO ATMOSPHERE.
8. VERTICAL OBROUND DOUBLE BOTTOM TANK DESIGNS ARE EQUIPPED WITH AN INTERNAL MONITORING PIPE EXTENDING INTO THE INTERSTITIAL SPACE. THESE TANKS ARE EQUIPPED WITH A METAL DIPSTICK ATTACHED TO THE UNDERSIDE OF THE CAP OF THE CONTAINMENT INSPECTION PORT. MONTHLY CHECKING OF THE INTERSTITIAL AREA USING THE DIPSTICK IS RECOMMENDED TO ENSURE THAT NO LEAKAGE OF THE PRIMARY TANK HAS OCCURED. IF OIL RESIDUE IS OBSERVED AT THE END OF THE DIPSTICK, THE TANK MUST BE TAKEN OUT OF SERVICE AND REPLACED. AS AN ALTERNATIVE TO DIPSTICK MONITORING, A FLOAT GAUGE CAN BE PURCHASED AT BMI FOR INTERSTITIAL TANK MONITORING.
9. TANKS INSTALLED OUTDOORS MUST BE PAINTED WITH CORROSION RESISTANT PAINT UPON INSTALLATION.
10. FOR LONGEVITY, INSPECT FOR AND REMOVE WATER THAT COLLECTS IN THE TANK BOTTOM.
11. CORROSION IS PRIMARILY CAUSED BY BACTERIAL CONTAMINATION OF FUEL AND/OR CHLORIDES IN WATER ACCUMULATED IN THE TANK BOTTOM. INTERNAL CORROSION MAY BE CONTROLLED BY:
i. INSPECTING & REMOVING ANY WATER THAT COLLECTS IN THE TANK BOTTOM; AND
ii. ADDING BACTERICIDES TO THE FUEL AT DELIVERY.
iii. A BOTTOM OUTLET TANK ALLEVIATES WATER IN THE TANK BOTTOM.
12. TANKS MUST NOT BE DRAGGED OR DROPPED & ONLY MOVED WHEN EMPTY BY THE TANK HANDLES PROVIDED.
13. WHEN REPLACING AN OIL TANK, LEAVE LOWER 6 INCHES OF FUEL IN THE OLD TANK. TRANSFER OF POTENTIALLY CORROSIVE SLUDGE TO A NEW TANK WILL PROMOTE INTERNAL CORROSION IMMEDIATELY.
14. INSPECT TANK AT LEAST ANNUALLY. A QUALIFIED TECHNICIAN SHOULD DO ANY REQUIRED MAINTENANCE.
