POL, ACME and QUICK DISCONNECT VALVES – Types of vapor
with drawal service valves.
Fixed Liquid Level Gauge. Clear vapor less than 80%: white
mist 80% or above.
Vapor Withdrawal Tube – Used on tanks where service valve
is not located on top of tank.
Base ring, stand legs, or mounting brackets.
Relief Valve – discharges LP-gas if the pressure in the
container is too high. If LP-gas is discharging, call the Fire Dept. and get
away from the container.
OPD – or Overfill Prevention Device is a valve designed to
assist LP-gas fillers to fill the cylinders to safe levels of propane.
Automatic Stop Fill Valve– with 1 3/4” ACME
Visible Sight Gauge – Available with remote sender.
Never allow your
LP-gas container to be filled above the maximum safe level as indicated by a
scale or the fixed liquid level gauge (outage). Do not use the visible gauge for
filling.
Do not use a wrench or pliers to close the
service valve or fixed liquid level gauge. These valves are designed to be
closed leak-tight by hand or screwdriver as appropriate. If wrenches are
necessary to stop a leak, the valve needs repair or replacement.
When tightening the POL Nut (left-hand thread)
on the service valve, draw it up snug with a proper wrench. This is a machined
male brass fitting which seats securely against a female seat in the POL valve
– no pipe dope is necessary. Acme/Type 1 valves have right handed threads
which are secure when hand tight, and on the Quick Disconnect/Type 2 Valves, the
male connection is inserted into the female connection on the cylinder valve.
(No wrenches required for both the Acme and the Quick Disconnect.)
When using container, slowly open service
valve all the way. Listen to the regulator. A continuous hiss may indicate a
leak or an open valve on an appliance.
Check all tank and the line connections
periodically to be sure they are tight. When testing for leaks, use approved
leak detector solution – not matches.
Make certain your container is properly
fastened in place.
Turn container with open part of container
guard towards trailer (travel trailer installation). This protects valves and
regulator against flying rocks and mud. Transport container in the proper
position in which it is used, with the valves closed and POL Plugs inserted for
POL Valves, or Dust Caps for Acme Valves. Secure the tank against falling or
rolling.
Check for leaks after connecting. Apply
approved leak detector solution to connections, turn off all burners and pilots,
and open service valve. Leaks will be detected by the growth of the bubbles. If
bubbles grow, tighten or repair the connection as needed. Repeat leak test until
problem is corrected.
LP-gas is non-corrosive, you need not worry
about the inside of your container. However, the outside should be kept free
from rust by a periodic coat of paint in a light reflective color. It is very
important to inspect and maintain the bottom and footring on the container.
Do not store LP-gas containers indoors or in
enclosed areas. Do not expose LP-gas container to heat. Always store with
service valve closed and plugged as required.
Do not attempt to repair any containers,
container valves, regulators or appliances by yourself. Use only trained,
certified LP-gas service personnel to perform repairs.

above 50%. |
