|Subject:||Gas Hose Change|
It has recently come to the attention of SEI that the specification for the gas hose used on the Green Dragon has changed. SEI was not informed by the supplier of the change at the time it occurred. The original hose (part number 006046) was rated for 150 psi at 70° F but has since been de‐rated by the manufacturer to 130 psi at 70° F. The 130 psi hoses have the rating printed on the outside of the hose.

Subject: Incorrect Position of Hopper Motor Plate
A Green Dragon dispenser was reported to have repeated problems with failure to load the primed sphere. Upon investigation, it was discovered that the motor plate in the hopper had been installed incorrectly. The motor plate is located in the hopper tube by three screws located 120° apart and includes the hopper limit switch which determines the position of the selector plate when it is stopped. The motor plate and switch were rotated such that when the hopper was stopped, the selector plate was not at the correct location. The consequences of this are that when the barrel opens to receive the primed sphere, the next sphere has not yet been loaded in the hopper and does not push the loaded sphere into the barrel.

Reference: SAFECOM 13-0286
The potassium permanganate currently used in pink/white Premo Fireballs is a very pure formula and is slightly more reactive with ethylene glycol. Customer feedback combined with in-house testing have confirmed that the new Premo Fireballs (pink and white) can display premature chemical reactions and more animated ignition characteristics when injected with pure ethylene glycol in warmer temperatures of approximately 70° F ( 21° C) or higher.

Several incidents have occurred when an operator incorrectly installed the outlet chute to the injection head. The gold nuts were left on the chute screws on the inside of the head and the black nuts on the outside. This action caused the chute to be offset inboard and blocked the primed spheres from exiting the dispenser.
Several operators have reported dripping from the water nozzles after a water test. An investigation has determined that the nozzle check valves are prone to sticking in the open position due to particulate contamination in the water.
An incident occurred when an operator removed and replaced the hopper in operation while failing to clear the top two spheres from the gate assembly. This action caused the gate to be jammed in the closed position.
This issue is currently addressed with a note on page 28 of the operating manual. The note states:
