TIP:
Raking (stirring) the top 1/3 of the mash every 15 minutes during lautering helps to remove any preferential flow paths and provides a more efficient
uniform lauter.
BOILING:
Once the level of the wort in your BK / HLT has reached your float switch, turn the corresponding heater control selector switch to AUTO and
adjust the set point on the PID to 220F to achieve a boil. That will fire the elements continuously.
CAUTION:
if you turn your heater control selector switch to ON when boiling, your float switches are bypassed and will NOT protect your heating
elements should you inadvertently drain the BK with the elements energized! Dry fired heating elements that fail are not covered under warranty!
TIP:
If the boil is too aggressive use the heater selector switch to de-energize one of the heating elements. Note that a proper boil is between a simmer
and a surging boil. Shoot for a 3-5% boil off rate per hour.
IMPORTANT:
To drive off DMS ALWAYS boil with the lid open!
After your boil is complete turn your heater power selector switch to the OFF position. You can either whirlpool manually with the stir paddle or connect
the pump to the system and recirculate through the tangential port on the side of the kettle. Either method provides a suitable whirlpool. Note that a
slow rotation is really all that’s needed. After whirlpool, close the lid and allow 15-20 minutes for the convection currents to slow and the hop and trub to
settle to the bottom center of the kettle.
The pumps included with the system are seal-less magnetic drive pumps. They
MUST NOT
be run dry or the impeller bearing surface will be damaged!
This is NOT covered under warranty.
Ensure the hoses and pump head are filled with liquid before turning on the pump. If you hear a loud squeal stop
the pump immediately!
Caution: NEVER
restrict the inlet to the pump. Always place flow throttling valves on the OUTLET of the pump ONLY. Failure to do this will cause
cavitation in the pump possibly leading to failure of the impeller. If you hear any grumbling or grinding in the pump STOP IMMEDIATELY as this is
cavitation. Cavitation failures are NOT covered under warranty.
Sanitize the chiller by either pumping StarSan or similar copper friendly sanitizer through the chiller. Alternately the chiller may be submerged (fittings
up) into a pail of sanitizer. Drain the chiller after the recommended time with the fittings facing down. Connect the chiller per the instructions on the
nameplate.
Drain off the first gallon or so of wort from the boil kettle to a waste drain to eject any solids in the piping and to ensure only clear wort flows through
the chiller to prevent plugging. Then divert the flow to the chiller. Adjust the wort flow and/or the cooling water flow to achieve the desired wort
temperature to your fermentor.
IMMEDIATELY
after use back-flush the chiller with hot water to eject any solids and wort. IMMEDIATELY soak the chiller fittings up in PBW or other
copper friendly cleaning agents for 30 min or pump through the chiller. Rinse with hot water and then soak in sanitizer. Allow to drain fittings down, and
then store with the chiller horizontal. Following this procedure consistently will give you a very long service life for your chiller.
Mash tun: Spent grains can easily be removed through the manway in the mash tun. Drain all remaining wort out of the bottom drain and then open the
door. Utilizing a non-marring hoe (available in our maintenance kit) rake out the spent grains into a tub. Remove the false bottom sections and spray them
off with hot water and allow to dry. Spray excess grain from the sidewalls and bottom of the kettles with a hose.
HLT/BK/MT: Due to the easy access through the top of the relatively small tanks, and small size of the chiller and pumps, it is usually fastest to scour the
kettles with a scrub brush mounted on a pole and spray them out with a hose. Optional cleaning tools are available through Blichmann Engineering to
make this a fast and thorough job. Alternately, you can utilize one of the heated vessels to heat and hold your CIP (clean in place) chemicals and use one
pumps to recirculate through the CIP ball and the second pump to return back into the chemical kettle. It is recommended that you turn off all heaters
while running the CIP system to avoid dry firing them. Tip your kettles forward so that all water drains out the bottom valve, leave the lid open, and allow
the kettles to dry thoroughly.
Tip: A spray of StarSan on the interior surfaces after cleaning will help prevent mildew between uses.
Tip: Place your chiller in-line with the pump to clean it at the same time.
Typical heating rates are 0.8-1.5 F/min.
Expect about a 5% boil-off rate
Strike water will cool about 10F when pumped from the HLT to the MT
Temperature loss in MT – less than 1F/hr
Temperature stability of control system approxi/- 1 F
