RECHARGING PROCEDURE FOR BLAZEX RANGE STORED PRESSURE DRY
POWDER MODELS
MODEL NO'S: XAS6, XAS9
THESE RECHARGE PROCEDURES SHOULD BE USED IF COMPLETE OR
PARTIAL USE OF THE EXTINGUISHER IS SUSPECTED
1. Check for signs of damage or significant corrosion to extinguisher. If found, do
not continue recharge procedure, mark extinguisher
“CONDEMNED” and inform
user. Ensure instruction label is legible, rectify if necessary.
2. Ensure pressure is relieved by inverting extinguisher and squeezing the levers
together slowly (whilst pointing nozzle down and away).
3. Remove hose and loosen headcap, using Blazex
bar adaptor
. (do not use
incorrect fitting spanners). Remove headcap slowly, allowing residual pressure to
escape through vent slots.
4. Empty residual powder from extinguisher body and discard.
5. Inspect the extinguisher inside, checking for caked powder or corrosion,
indicating moisture inside the cylinder, rectify or replace extinguisher if found.
6. Recharge the extinguisher body with new dry powder, ensuring correct quantity
and type.
Never mix different types of powder as pressure and moisture
may develop as a result of a chemical reaction
.
7. Remove syphon tube, tube holder, spring and spindle. Thoroughly clean any
residual powder from chamber using a soft brush or valve tool. Remove 'O' rings
from spindle, clean 'O' ring grooves and lubricate lightly using silicon gel. Fit new
'O' rings ensuring they are centralised.
8. Refit spindle, spring and tube holder to valve. Refit syphon tube. Fit new valve
'O' ring.
9. Clean cylinder neck threads and 'O' ring seat. Refit headcap, tighten using Blazex
bar adaptor
.
10.
With the valve open (depressed), pressurise through valve, to 12 bar (@
+20ºc) using dry air or Nitrogen, close valve (release) and shut off pressure
supply. Remove pressurising adaptor slowly, as a small amount of pressure
may remain in the filling line.
11. Refit safety pin and seal (in accordance with service colour code).
12.
Fit new discharge hose „O‟ring and refit discharge hose.
13. Check for leakage. Record recharging details, including new weight on service
