NORMAL PROCEDURES
The smoke system includes features for refilling the smoke tanks and smoke generation:
A) REFILL
A separate refill hose is delivered with the smoke system which has to be used for filling the
smoke oil tanks from the paraffin oil supply cansister or barrel.
1. Refill hose
CONNECT hose nipple to quick
connector at the fuselage bottom;
IMMERSE the other end into the paraffin
oil in the canister/barrel
2. Switch "SMOKE REFILL"
ON
N O T E
The refilling should start within max. 30 sec. If this is not the case, the refill lines,
fittings and filter (if installed) have to be checked for soiling or leaks. Refilling
procedure can be supported by reducing the suction height e.g. lifting the canister.
The fully filled status is sensed by the floating device which automatically switches
the refilling off.
