Installing Sensor & Plumbing For Mash Control:
Important!
Do not install the sensor directly into a mash tun!
The grain greatly impedes the convection and transfer of heat.
It is VITAL to the performance of the product that the sensor be
installed so that it is measuring the temperature of the wort
returning to the top of the mash bed. Installing the sensor
directly into the mash tun will cause severe overshooting,
oscillation, scorched wort, and possibly equipment damage!!
If you have purchased the Tower stand:
install the sensor for
the MASH controller in the port indicated in Fig. 24. Note that
the HLT sensor will be mounted directly in the hot liquor tank.
Tip!
We recommend ½” (12mm) ID hose for connecting the Tower to
your system. Silicone hose, while expensive, will last a lifetime and
can withstand continuous use at boiling temperatures. We
recommend 3/4” OD thick wall hose.
Warning!
ALWAYS use hose clamps on all hoses!
Connecting to other systems:
Refer to the schematic of Fig 25. It is
VITAL to the performance of the system to connect it in this manner.
Connect the outlet valve of your mash tun to the inlet of the pump.
Install a flow control valve after the pump. Then plumb through the
sensor, and lastly back to the TOP of the mash bed. Note – it is also
acceptable to switch the order of the flow control valve and the sensor.
Installing the sensor in your own system:
locate the sensor
according to the schematic in Fig. 25. A close-up of the sensor
installed in a pipe T (not included but available through
McMaster.com 4464KK51 if needed) is shown in Fig 26. Note
that the tip of the sensor must protrude into the middle of flow
cavity for it to accurately measure the wort temperature.
Installing an AutoSparge
tm
in your system:
We highly
recommend using the Blichmann Engineering AutoSparge
tm
for
this application (Fig 27) which is available separately. Lastly,
connect the remaining fitting on the 3-way valve to the inlet of
your brew pot.
Tip!
As shown in Fig 27 place a pipe T (not included but available
through McMaster.com 4464KK51 if needed) on the inlet of the
AutoSparge
tm
. This will allow you to connect it to the HLT and the
mash recirculation simultaneously with no need to switch hoses at
sparge time! A valve is not needed on the elbow since the valve on
the HLT will stop wort from flowing that direction.
