Open the PB circuit and set to maximum psi. Ensure
liquid is owing through this circuit as indicated
by frosting on the pipes. Let liquid in the tank build
pressure close to safety setting. Once desired pressure
is reached, open liquid valve. When liquid is out of the
tank and pressure is still high, open the vent and gas use
valves. If a nal line manifold is already connected to
the gas use valve, purge through the manifold to insure
that there is a ow through the gas use circuit and any
moisture is purged out before liquid is introduced into
this circuit.
Once pressure is blown down to 5 psig, close the liquid,
vent and gas use valves.
6. Fill the Perma-Cyl tank with product and let the liquid
in the tank build pressure close to the safety setting.
Ensure the product is owing through and purging the
economizer lines. Control the pressure by opening the
gas use and vent valves. Once pressure is approximately
5 psig, close the gas use and vent valves.
7. Fill the Perma-Cyl tank with product per the table and
let the liquid in the tank build pressure to close to the
safety setting. Once the desired psig has been reached,
open the gas use and vent valves. Once pressure is
approximately 5 psig, close the gas use and vent valves.
Note: The purge gas should be cooling the tank.
If the tank vent line is HOT, always purge
until the vent line is cool or even frosted.
A new, warm tank should go through a
minimum of four or ve purge cycles before
lling with liquid.
Filling the Tank After the Cool Down
Process is Complete
1. If equipped with a bottom ll valve, the bottom ll
valve and the tank vent valve are the valves to be used
to ll a warm tank.
2. Have the driver start the pump and slowly deliver the
liquid into the tank. Observe the tank pressure and
control the pressure by venting the tank down or by
using the top ll valve to control the pressure.
3. As the lling proceeds and the tank gets cooler, you
should be able to pinch off and, in some cases, close the
vent valve. We recommend that you do not ll the tank
to the full trycock on the rst ll. Fill to 75% in order to
allow for liquid expansion as the tank contents absorb
heat while the metal continues to cool down over time.
