How to perform a 7-Point Tune-Up on your Dual Sizer

Step 1. Set your inflator to 9.0 seconds at 90 PSI. Tap the foot pedal or press the inflation button 3 times to cycle the unit. This will blow out any foreign particles that may have entered the system.

Step 2. Remove the filling outlets and gas supply line from the unit.

Step 3. Spray silicone lubricant into gas supply port (located in the back of the unit) and into the latex inflating port(s) on the top of the unit. IMPORTANT: Only use spray silicone lubricant. Do NOT lubricate the unit with an oil-based lubricant. Spray silicone lubricant is available at your local hardware or automotive store.

Step 4. Tilt the inflator to the right and hold for a few seconds. Then, tilt the inflator to the left and hold for a few seconds. This will allow the silicone lubricant to fully enter the unit.

Step 5. Attach the gas supply line and pressure the unit. Do not attach filling outlets.

Step 6. Set your unit to 0.3 seconds at 80 PSI. Cover the inflating ports on the top of the unit with a rag and tap the foot pedal or press the inflation button 10 times to fully lubricate the unit.

Step 7. Before using your inflator, it is important to blow out all excess lubricant. Place a clean paper towel over the outlets and tap the foot pedal or press the inflation button to cycle the unit. If the paper towel shows any lubricant, it is necessary to continue cycling the unit. When the towel shows no signs of lubricant, replace filling outlets. Now your inflator is ready for use!

What air compressor should I use with my Dual Sizer?

Most air compressors are factory set to automatically cycle on at 90 PSI and automatically cycle off at 120 PSI. Conwin's automatic sizers must have a steady supply of air or gas to produce equal sized balloons. For accurate sizing, it is essential to work within the limits of the cubic-foot-per-minute capacity of the air compressor.

Important Guidelines When Using an Air Compressor:
• Compressor must build up tank pressure before inflating balloons.
• The output setting on the air compressor should not exceed 80 PSI. If the compressor is set higher than 80 PSI, the automatic sizer will outperform the compressor's storage tank capacity.
• After each job, blow down the compressor to remove water collected in the tank during compression. The Dual Split-Second Sizer will require factory rework and re-calibration if moisture enters its system.
• Power surges will affect the accuracy of the Dual Split-Second Sizer - line voltage must be steady at 120 volts.

Air Compressor Hook-Up Instructions
1. Verify the air compressor has a primary dirt and moisture filter prior to attaching the hose. Attach the quick disconnect socket to the air compressor. Plug-in the air line into the socket on the compressor and into the back of the inflator.

2. The color of the filter on the end of the Air Compressor Hook-Up line will change from black to clear if moisture is present in the line. If this occurs, change the primary moisture filter on the air compressor and replace the filter on the end of the air line.

Troubleshooting recommendations for your Dual Sizer.

1. Confirm that the cylinder valve is fully open. If you're using one of our older, non-digital models make sure that you're using a 110-volt transformer. Note: If a 110 volt unit is exposed to 220 volts it will be damaged beyond repair.

2. Make sure that you are following the instruction sheet with size-setting chart. If you've lost your instructions, you can download the PDF by visiting our instruction sheet page.

3. To adjust the 2nd stage regulator, unlock the black knob by pulling up. Turn the knob clockwise to increase the pressure and increase the speed of inflation. Turn the knob counter clockwise to decrease the pressure and speed of the inflator. Press the knob down to lock in place. Recommended settings: 5-Inch balloons set at 50 PSI, 11-Inch+ balloons set at 80 PSI.

4. If you're using an air compressor, confirm that the air compressor meets the requirements listed on the instruction sheet. If the storage tank is too small, the sizer will outperform the compressor and 9-inch and larger balloons will vary in size between cycles. The compressor must have a moisture trap. If moisture enters the sizer the timers will be damaged.

5. Review the mode settings on Dual Split-Second Sizer. (For Digital Model Only) Make sure you use only timer A when sizing two balloons identically. The LED's on the control panel indicate which timers and outlets are on.

6. If using the non-digital model, confirm that you are using the same size outlets on both sides.

7. When inflating 9" and larger balloons, adjust the size setting every 1/3 of a cylinder. This assures that the size of balloons is consistent as the cylinder pressure decreases.

8. If the Dual Sizer doesn't size accurately on both sides confirm the following: You are using same size outlets on both sides.(Non-Digital Model). You are using the proper mode setting (Digital Model). You are inflating the same type of balloons, (metallic balloons, Jewel Tone balloons and Standard Color balloons all inflate differently). Mixing balloon color types will appear to create inconsistent sizing due to the varying shape of the balloons. Unit has not been exposed to moisture.

9. After reviewing the above, if you are unable to correct the problem, do a 7-Point Tune Up on your inflator.
