Operation

1. After a sample is received into the receptacle, turn the pump motor ON for at least 5 (See

note below) minutes to circulate the fluid.

•

A 5-gal system requires a minimum circulation time of 5 minutes or until the volume

in the receptacle is circulated five times.

•

A 10-gal system requires a minimum circulation time of 10 minutes of circulation or

until the volume has been circulated five times.

NOTE: The pump is rated at approximately 5.0 gpm at 0 psig backpressure and a fluid

viscosity of 100 SUS (21.6 CTS) at 60°F (16°C).

For most light to medium crude oils ranging up to API 24 with kinematic viscosity less than

160 CTS at 60°F (16°C), 5 minutes of circulation time should adequately mix the tank volume.

For most crude oils heavier than API 24, with a kinematic viscosity greater than 160 CTS and

temperatures below 60°F (16°C), consider allowing additional circulation time to ensure the

tank volume is thoroughly mixed.

2. While the circulating pump is ON, open the sample draw-off valve (item 11), allowing

the sample to flow directly into laboratory glassware. Close the sample draw-off valve

(item 11) and cap the laboratory sample transport receptacle immediately.

3. To drain the (tank) receptacle, perform the following steps:

a. Turn the circulating pump ON.

b. Close the return valve (item 15A).

c. Open the drain valve (item 15B) and the pump isolation valve (item 15 C) and allow

the receptacle to drain.

d. When the receptacle is empty, close the pump isolation valve (item 15 C) and open

the return valve (item 15A) to drain the re-circulating tubing (item 9).

e. Turn the pump motor off, and close all valves.

4. To open the cover (closure) on the receptacle, perform the following steps:

a. Open the sample draw-off valve (item 11) to relieve pressure from the receptacle.

b. After the pressure is relieved, loosen the T-bolts and swing them away from the lugs

on the closure.

c. Grasp the handle on top of the closure and swing it back towards the hinges to open

the closure.

5. Thoroughly clean the receptacle after every sampling batch to prevent cross-

contamination of sampled fluids.
