Before you begin your installaon, check to be sure that there is sufficient cell
phone signal strength at your sugarbush for SapCheck to operate.
Note: If you purchased your SapCheck unit from a dealer, you will need to
first contact The Bosworth Company to purchase a SapCheck Support Plan
for your unit. (See page 20 for details.) Purchasing a plan will allow your
SapCheck device to be assigned a SapCheck phone number to communicate
on a cellular network. If you purchased your SapCheck directly from The
Bosworth Company, then a phone number has already been assigned to
your SapCheck, and your unit is ready to send and receive text messages.
Remove the SapCheck Controller from the packaging and aach the antenna
to the box as shown in the figures below.

Bring the SapCheck Controller and power cord to your sugarbush. Be sure to
have the cell phone with you that is going to funcon as the Command Num‐
ber.
While at your sugarbush, connect the SapCheck Controller to power. If there
is sufficient cell phone connecvity at the sugarbush, then within approxi‐
mately two minutes aer powering on, SapCheck will send a text message to
the Command Number, indicang the soware version that is running. You
can text the command “Get signal” to SapCheck and it will return a percent
indicator of cell phone signal strength.
If you do not receive this text message, or if the percent signal strength is
below 10%, then there may be insufficient cell phone signal strength at your
sugarbush for SapCheck to operate.
In this case, you may return SapCheck for a full credit if you act within 15
days of date of purchase and if you return SapCheck in its original shipping
carton.

SapCheck requires 120 VAC power to the controller, and it can control vacu‐
um pumps that operate on 120 VAC. Vacuum pumps up to 1/2 Hp can be
directly controlled with SapCheck.
However, SapCheck is not limited to controlling pumps that plug directly into
the SapCheck Controller. SapCheck can be used to control power to any
electrical device that is powered by 120 VAC and does not draw more than
370 was of power. This includes the possibility of controlling 120 VAC re‐
lays that control larger pump equipment.
SapCheck operates by sending and receiving text messages over a cellular
network. To operate properly, cell phone communicaons must be available
at the sugarbush, but only to the extent of being able to send and receive
text messages.
Figure 2
SapCheck is used to remotely monitor and control vacuum pump operaon
at maple syrup sugarbushes. It consists of a controller together with three
(3) sensors and associated connecng wires to monitor vacuum and tem‐
perature condions at the sugarbush. SapCheck also sends an alert when
the sap in the collecon tank has reached a user‐specified target level.

SapCheck should not be used to power any device that requires more than
370 was of power. Using SapCheck with such a device could pose a risk of
fire or electrical shock.
The SapCheck controller requires protecon from the elements. The unit
should be deployed in a dry environment and should not be operated in
temperatures below 20°F (-6°C) or above 90°F (32°C)
Under no circumstances should the SapCheck controller be opened or disas-
sembled. Tampering with the SapCheck equipment will void the warranty.
Each SapCheck unit has an associated phone number that is used for sending
text messages to it. If you purchased your SapCheck unit directly from The
Bosworth Company, that phone number has already been assigned to your
device and your unit is ready to send and receive text messages.
If you purchased your unit through a dealer, you must call The Bosworth Com‐
pany (1‐888‐438‐1110) or visit the company website at hps://
thebosworthco.com/acvate to purchase a support plan that will provide the
cell phone communicaons necessary for SapCheck to operate. When you
purchase a support plan, your SapCheck unit will be acvated and you will
receive your SapCheck’s phone number.
To purchase a support plan you will need to provide the SapCheck ID # printed
on the boom of the SapCheck Controller. (Figure 3 shows an example of a
SapCheck with ID # “D0000XT003”.)

Command Number SapCheck will only receive text commands from cell phone
numbers that it recognizes. Each of these numbers is re‐
ferred to as a Command Number. The “Set User” text com‐
mand can be used to add or delete cell phone numbers
from this list.

Number
This is the phone # to which you will send text messages to
your SapCheck device. You can add this phone # to your
“Contacts” on your cell phone under the name “SapCheck”.
(Note: if you have more than one SapCheck device, you may
want to list each in your Contacts giving it a unique name,
such as “SapCheck—Marshfield Rd”.)
Service mode When service mode is turned on, SapCheck will only re‐
spond to text commands sent from The Bosworth Compa‐
ny’s service support line. This mode is only acvated upon a
user’s request and allows Bosworth to send and receive
diagnosc text messages to the unit for troubleshoong
purposes.
Acvated A SapCheck unit is “Acvated” when its wireless communi‐
caons components have been configured to send/receive
text messages on a cell phone network. To be acvated, a
SapCheck unit must be covered by a Support Plan. An ac‐
vated SapCheck has an assigned SapCheck phone #.
Inacve A SapCheck unit is “Inacve” if its wireless communicaons
components have not been configured to send/receive text
messages. An inacve SapCheck unit has not been assigned
a SapCheck phone #.
Deacvated Unless a customer purchases addional support plan cover‐
age, a SapCheck unit with an assigned phone # is Deacvat‐
ed once the term of the Support Plan ends. When a Sap‐
Check unit is deacvated, it can no longer send/receive text
messages and it no longer retains its originally assigned
SapCheck phone #. If a new Support Plan is purchased, a
new phone # is assigned to the unit and communicaons
are restored for the length of the new Support Plan.

The SapCheck Controller unit must be co‐located near your pump. It should
be installed in a dry, venlated enclosure that protects it from the elements.
These instrucons assume that SapCheck will be installed in the same enclo‐
sure that contains your vacuum pump.
Your SapCheck unit has been pre‐configured to send text messages to the
cell phone number (a “Command Number”) you provided. You can send
text messages to your SapCheck unit at the SapCheck phone number listed
with this installaon note. We suggest you add this phone number to your
“Contacts” on your cell phone, giving it the name “SapCheck” or, if you have
more than one SapCheck unit, a name referencing the sugarbush locaon
where the unit is deployed. That way, you will be receiving and sending text
messages either from/to “SapCheck” or from/to the sugarbush locaon
where SapCheck is operang.

1. Locate the SapCheck controller (A) within your pump enclosure. (Make
sure that you have previously installed the antenna (Q) onto the control‐
ler. (See page 3 for details.)
2. Aach the Male Sensor Connecon Plug (D) to the Female Connector (N)
on the top of the SapCheck box.
3. Note: If you do not wish to install the Tank Float Switch provided, simply
connect the two Float Switch (G) wires coming from the Male Sensor
Connector Plug (D) to the Float Switch By‐pass wire (P).
4. Note: The tank float switch (B) is to be installed in your sap collecon
tank. The maximum tank wall thickness that the float switch can accom‐
modate is 3/8 in. The switching end of the float switch must be installed
poinng down.

5. Determine the desired sap level height in your collecon tank at which
you want the SapCheck unit to send you a Sap Alert Level message. Us‐
ing the 13/32” drill bit, drill a hole 2‐3/4” above this height in your tank
to mount the float switch. Remove the nut from the Float Switch (G) and
pass the float switch wires through this hole from inside the tank wall
out. (Ensure that the nylon washer sits between the inside tank wall and
the interior float switch nut.) Pass the nut over the wires on the outside
and secure the nut onto the exposed threads of the tank float switch
using an adjustable wrench.
6. Drill a 3/8” hole in the pump enclosure near where the SapCheck Control‐
ler is to be located. Pass the end of the 12’ float switch cable (C) through
this hole and connect the cable to the SapCheck Float Switch wires (G)
using the red Posi‐Tap connectors. (See Figure 6.) Wrap the connec‐
ons with waterproof electrical tape. (Note: If your sap collecon tank is
further than 12 feet from the SapCheck Controller, you can splice addi‐
onal wires onto the exisng Float Switch wires without affecng the
operaon of the Float Switch.).
Figure 5a pictures tank wall from above, showing the installed float switch with
exterior nut holding switch in place. The nylon washer fits between the inside
nut (non‐rotang) and inside tank wall to ensure secure fit with no leakage.
Figure 3b shows installed float switch, with boom of switch roughly 3‐1/2 in

9. For best results, SapCheck’s vacuum sensor should be installed so that it
avoids coming in contact with sap. We recommend loing it approxi‐
mately 6 inches above the mainline near the pump inlet. This can be
accomplished by installing a T‐fing in the mainline near the pump that
can accommodate a 6‐inch length of tubing terminated with a plug. (See
Figure 8.)
Tap a 1/8” NPT hole in the tubing plug. (First drill a 21/64” hole and
then use a tapping tool to create a 1/8” NPT tap inside the hole.) Note:
Locate this tapped hole so that it can connect to the SapCheck Controller
using the approximately 30” long wire coming from the Controller and
terminang in the male vacuum sensor connector (F). Using an adjusta‐
ble wrench, install the vacuum sensor transducer (H) into the tapped
hole, using Teflon tape for a leak‐proof connecon. Connect the male
vacuum sensor plug (F) into the female receptacle on the vacuum sensor
transducer (H). (See Figure 8.)
Figure 8
10. Connect your vacuum pump to 120 VAC Out power receptacle (M) on
the SapCheck Controller. If your vacuum pump has an ON/OFF switch,
set it to the ON posion.
11. Connect the female end of the Controller power cord (J) into the male
120 VAC In power plug (L) on the Controller and plug the other end of
this cord into 120 VAC power. The green light on the SapCheck Control‐
ler will illuminate. Within 2 minutes, you will receive a “Monitoring Sys‐
tem is ON” text message on the cell phone set up as the Command Num‐
ber for your device. (Ensurethatyourcellphoneispoweredonandhas

SapCheck is now ready to receive and respond to text message commands
from your cell phone to monitor and control your vacuum pump operaon.

When SapCheck receives a text message from a Command Number, it will
always reply by texng back a confirming message. This indicates that Sap‐
Check has received and processed the text message command that you sent.

To ask SapCheck a queson, you simply begin the text message with a ques‐
on mark (?) or the word “get”. SapCheck can provide you with temperature
and vacuum informaon as collected from its temperature and vacuum sen‐
sors. Addionally, SapCheck will tell you whether or not the level of sap in
your sap collecon tank has reached the tank float switch. The “?” (get)
commands allow you to inquire about the readings from these sensors:
 “?temp” OR “get temp” returns current temperature
 “?vac” OR “get vac” returns current vacuum
 “?tank” OR “get tank” returns a message indicang whether or
not the sap has reached the sap alert level
(Note that the sap alert level corresponds to the height at which
you have installed the float switch on your sap collecon tank.)
Addionally, you can send the following text messages:
 “?status” OR “get status” returns a message indicang current
temperature, vacuum, tank full status and pump operaon state.
Note: This is the most efficient way to monitor condions at the
sugarbush as it returns all informaon in one text message, as
opposed to mulple individual messages for each piece of infor‐
maon.
 “?sengs” OR “get sengs” returns a message indicang the
values of all the control or alert sengs that you have previously
defined.
 “?version” OR “get version” returns the current version number
of the SapCheck soware installed in the Controller.

SapCheck can automacally turn your vacuum pump on/offbased on the tem‐
perature at your sugarbush. You can define one temperature at which the
pump will turn on, and a second temperature at which the pump will turn off.
For example, you might want to wait unl the temperature warms up to 33°F
before turning the pump on (to be sure that any ice inside the pump has melt‐
ed) and to keep running unl the temperature drops below, say, 30°F .
To set the temperature value at which the pump will turn on, send the text

SapCheck will only respond to text commands from cell phone numbers that
have been registered with it using the “set user” command. To add a new
Command Number for a user with cell phone xxx‐yyy‐zzzz, send the text mes‐
sage command below:
set user xxxyyyzzzz
To delete xxx‐yyy‐zzzz from the command number list, text:
set user xxxyyyzzzz del
Any acve command number can issue a SapCheck command, and all acve
command numbers will receive SapCheck alerts. Only the command‐issuing
number will receive a response to a SapCheck query.
To make a command number inacve, text
set user xxxyyyzzzz act off
Inacve command numbers will not receive SapCheck alerts, and SapCheck
will not process any command from an inacve number with the excepon of
the command to make the number acve
set user xxxyyyzzzz act on
The “get user” text command returns a list of all Command Numbers and
their status (acve/inacve).

For product support purposes, SapCheck can be put into “service mode” by
texng the command
service control on
When in service mode, the unit will respond only to command texts from a
special Bosworth Service Number. While in service mode, all command‐
confirming texts are sent only to this number. When this command is iniat‐
ed, SapCheck texts the following message to the user:
SERVICE CONTROL ON
This message indicates that the unit is currently under "Service Control", and
that no commands will be accepted from any user Command Numbers while
in this mode.
When service mode is terminated, SapCheck resumes responding to texts
from the user’s Command Number. The user receives the following text to
indicate that service mode has been terminated:
SERVICE CONTROL OFF

The SapCheck vacuum sensor is factory‐calibrated prior to product shipment.
However, it is possible for sensor accuracy to driover me. Addionally,
you may choose to calibrate SapCheck’s vacuum sensor to more closely
match vacuum readings of a vacuum gauge installed on your sap line. For
these reasons, SapCheck provides a set of commands that you can use to re‐
calibrate its vacuum sensor.
Re‐calibrang the SapCheck vacuum sensor involves seng two different
vacuum readings, one at zero vacuum (atmospheric pressure) and one at as a
high a vacuum as you can obtain on your system as read by your calibraon
gauge. Follow the steps below:
1) With your pump system running so that your calibrang gauge reads 0 in
Hg vacuum, text the following command to SapCheck:
set calibrate lowvac 0.0
2) With your pump system running so that your calibrang gauge reads as
high a vacuum reading as possible, text the following command to Sap‐
Check

set calibrate hivac <##.#>
where <##.#> is the vacuum reading on your calibrang gauge.
3) Aer seng the low and high vacuum points, text the following com‐
mand to SapCheck
set calibrate
The Calibrate command causes SapCheck to install the new calibraon
sengs and automacally reboot.
4) Issue the following SapCheck command to restart SapCheck:
reboot
When SapCheck restarts, the new calibraon sengs will be used for re‐
porng vacuum sensor readings.

Your SapCheck Support Plan provides cellular network connecvity for your
SapCheck unit. SapCheck units become acve once a Support Plan is pur‐
chased. A SapCheck Support Plan provides up to 1500 messages per month
and can be purchased to cover from 1 to 6 months’ operaon. Both messag‐
es “sent” and “received” by the SapCheck unit are counted toward the 1500
monthly message limit. Addional charges apply for messages above the
1500 monthly message limit. Contact The Bosworth Company for more de‐
tails.
