MYSTIC
INSTALLATION
PROPER INSTALLATION IS IMPORTANT. IF YOU NEED ASSISTANCE, CONSULT A CONTRACTOR, ELECTRICIAN
OR TELEVISION ANTENNA INSTALLER (CHECK WITH YOUR LOCAL BUILDING SUPPLY, OR HARDWARE STORE
FOR REFERRALS). TO PROMOTE CONFIDENCE, PERFORM A TRIAL WIRING BEFORE INSTALLATION.

Connect the AC adapter to Mystic and plug into outlet. The display will
briefly light up all the indicator lights (self test). Next the display will show
the unit of measurement codes and then will show the barometer function
light and the center display will show a pressure reading. Leave Mystic in
this mode for two hours. Do not activate the switch at the bottom of
the case. At the end of this two hour period, Mystic will be ready to have
the pressure adjustment performed.
Form a drip loop with the wire at least eight inches
below the exit from the sensor and at least eight inches
below the point of entry into the building. Anchor any
exposed wire with insulated cable clips. Run the wire
through the building to the location where the indicator
will be located. Caulk any holes when done.
Unplug the AC adaptor and disconnect the wires. Mystic is now ready for the final installation.
The adjustment that you have made will always remain intact.
Now calibrate the barometer for your altitude. Obtain the current barometric
pressure for your area by calling a near-by airport or an individual who has a
properly set barometer. Insert a small screw driver into the recessed slotted
screw at the back of Mystic. Turn the screw while observing the pressure read
out on the front of Mystic. Due to the sensitivity of this adjustment, the numbers
on the display may fluctuate during this procedure. It may take a minute to
achieve the exact setting. Once the unit is set, move the toggle switch to the
right (auto) one time to lock in the setting.
Mount the temperature sensor assembly with the two
large wood screws. Select a location that is protected
from direct sunlight and sheltered from rain and physical
damage. (A north exposure, six feet above the ground
will give the best results.)
