BULLDOG PUP INSTRUCTIONS
1. Set Up – Other Items Needed to Transfer Wine
1” Tri Clover wine outlet fitting can clamp directly to 1 ½” Tri
b. A light weight Tri Clover Butterfly
Valve can be sandwiched between wine outlet and 1 ½”
Tri Clover hose fitting. Using
1 ½” valve is much less restrictive than 1”.
Gas inlet on wand is ¼” MNPT. Work with your gas
supplier for gas fitting set up to
d. You can use various types of inert
gas but Nitrogen is the most economical. CO2 will
We advise use of Food Grade gas so bottles will be certified clean.
2. Getting Started
wand in barrel and seat bung in snugly. note: 50mm bungs are standard, 48mm
are also available.
sure stainless steel lever arms of Speed Ear are in up position.
3. Sealing the Barrel
the long section of Brass Adjuster to tighten lightly. (If using without Speed Ear turn
approx. 2 revolutions to expand bung to
seal tight in bung hole).
b. Press down the lever arms of Speed
Ear to finish expansion of the bung to seal tight
4. Introduce Gas
the gas inlet Ball Valve.
b. Start gas introduction slow. The high
end of safe gas pressure in barrels is 15 psi.
c. A 20 psi Pressure Relief Valve (PRV)
is installed to alert when pressures have exceeded
d. If gas escapes the PRV immediately shut off gas valve at Pup.
why your pressure is too high (see IMPORTANT below)
5. Setting Height Position
Brass Adjuster top cap clockwise to loosen tension.
the wand slowly down monitoring Sightglass until lees are barely detected.
wand slightly until lees disappear, your are now just above the lees bed.
lock the wand at the height position turn Brass Adjuster cap counter clockwise.
close to the end of a racking, shut gas valve and use residual pressure to finish
a watch to time rackings can help you estimate when to shut off gas for economy.
c. At 15 psi a 60 gallon barrel should empty in 3 minutes,
this can vary with length and height of run.
- Do not exceed recommended pressure – 15 psi.
- Inspect PRV regularly-replace yearly with regular use.
- Do not use the ring on PRV to release residual pressure
in barrel, this will shorten the life and reliability.
- Rack sound barrels without obvious flaws. Remember they are wood barrels
not steel pressure tanks.
not use a flow meter as a regulator the pressure can creep to 50 psi.
- Seek professional advice from your gas supplier about proper regulators to
- If the Brass Adjuster
is hard to slide, use food grade silicone spray sparingly.
