174 • Section 7 — LP-Gas Systems Cayman 2006
Filling the LP-Gas Tank:
1. Turn OFF pilot lights, all appliances and the engine. Close all
vents, doors and windows to prevent vapors from entering the
motorhome. Turn off the electric valve.
2. Remove dust cover. Screw Fill nozzle to fi ll valve.
3. Turn ON dispensing pump, then open 80% bleed valve.
4. Open valve on fi ll nozzle and dispense liquid into the tank.
5. Close valve on fi ll nozzle as liquid just begins to expel from
80% bleed valve. The overfi ll protection valve prevents fi lling
the tank to more than 80% of the rated capacity.
6. Close 80% valve and shut off dispensing pump.
7. Open high-pressure bleed valve on fi ll nozzle to remove
pressure between dispensing pump and fi ll nozzle. Remove
nozzle from the fi ll valve.
8. Install the dust cover.
9. LP-Gas appliances (especially the refrigerator) may have
diffi culty starting after a period of non-use. To speed the
process of supplying fresh fuel to the appliances, light the
stove fi rst.
WARNING:
It is common for small amounts of LP-Gas to escape
and evaporate during the fueling process. Protect bare
skin. Instant freezing will occur if exposed to LP-Gas.
CAUTION:
Pressure inside LP-Gas tanks can reach over 200
psi when exposed to direct sunlight. A high-pressure
safety relief valve will purge excess high pressure, if
necessary. LP-Gas will stop vaporizing as the LP-Gas
tank temperature approaches -44º F.
Tank Operation
• Open the primary shut-off valve located on the LP-Gas tank.
• Turn on the electric LP-Gas valve to allow gas to fl ow to the appliances.
• Turn OFF the electric valve and the primary valve on the LP-Gas tank when the tank is being fi lled, when
driving, in between trips and when in storage.
• Hand-tighten the primary valve only. DO NOT use a wrench or pliers, as this will over-tighten the valve.
• The primary valve is designed to be closed by hand. Over-tightening the valve may permanently damage
the valve seat.
NOTE:
In some states and Canadian provinces, it may be illegal to drive the motorhome while
primary valve on the LP tank is open.
