The operation of any confectionery bar where carbonated drinks are served necessitates the installation of a carbonator and a tank of carbon dioxide gas. Once installed, little trouble is usually encountered with the carbonator. Owing to the necessity of continual tank replacements, it is recommended that an extra tank (but only one) should be kept in reserve at all times.

As replacements are made, it is essential certain procedures are carried out to eliminate any gas leakage after a change has been made. The proper procedure is as follows:

1. Close the cylinder valve by turns ing clockwise.

2. Close the regulator outlet valve by turning clockwise.

3. Turn the regulator adjusting key in a counter-clockwise direction until it is loose.

4. Unscrew the regulator coupling nut from the cylinder valve outlet.

5. Replace the outlet cap, and prepare the tank for shipment.

6. Replace used tank with full tank, and remove outlet cap.

7. Replace regulator coupling nut on new tank.

8. Turn regulator adjusting key in clockwise direction until tight.

9. Open regulator outlet valve by turning anti-clockwise.

10. Open cylinder valve outlet by turning anti-clockwise.

11. Adjust pressure to 120 pounds, as

indicated on regulator pressure gauge. On completion of the transfer, it is essential that every used tank is returned to the distributor immediately. In order to avoid possible error and additional charges, it is advisable to label these as ttEmpty Iron Cylinders Returned."

Always store gas cylinders in a clean, dry, cool place away from odors, salt or other corrosives. Do not expose the full cylinders to dampness, heat or sunshine, or the empty ones to dampness. Always close the valve on empty cylinders.

Owing to the high cost of gas in todayis market, it is essential every effort should be made toward obtaining as much life as possible out of each tank. This precaution should take place as soon as they arrive, as the cylinders are jolted around considerably in transit, there is always a possibility of the outlet cap becoming loosened which might result in leakage. Therefore, just as soon as a shipment of gas is received, take a wrench and tighten the small outlet cap. If the valve is suspected of leaking, test it with a soap solution. Recurrent bubbles will show a leak if one exists. If it should be necessary to retain a cylinder longer than 30 days without emptying it, the outlet cap should again be tightened. The small round brass cap, cylinder safety valve, should not be tampered with. It protects

the small copper disk which is placed there to allow the contents to escape in the event the cylinder is exposed to extreme heat.

Loss of C02 gas may occur through gas line couplings, carbonator connections, packing, and regulators or other equipment. Proper care should be exercised to use good fiber washers in all gas couplings. All connections should be inspected frequently and tightened. Test all gas connections at least once a month by use of a shaving soap solution. The manufacturer is not responsible for leakage of this kind after cylinders are delivered.

Gas leaks may be located by the following procedure:

When closing at night, note should be made of the pressure shown on the regulator and carbonator gauge. Then tightly close (1) the cylinder valve, (2) the regulator outlet valve, (3) city water inlet Valve to the carbonator, and (4) the soda water outlet valve to the fountain. This completely isolates the carbonator and the regulator. In the morning note, the pressure reading on both gauges. If the regulator gauge pressure has dropped, there is a leak between the cylinder valve and the regulator outlet valve. If the carbonator gauge pressure has dropped more than
