9 AquaSmart Boiler Control Manual
2-in-1 “Integrated Unit” Instructions
This is very important for successful control operation.
1. Remove the existing immersion well. Clean the
threads in the boiler port tapping. Follow all applicable
safety codes, rules and guidelines for removing/
installing immersion wells.
2. Apply pipe sealant to the 2-in-1 sensor threads and
install it securely into the port. BECKETT
RECOMMENDS ONLY TO USE TEFLON TAPE OR
RECTORSEAL NO. 5 PIPE SEALANT.
3. Tighten with 1-1/8” open end or box wrench (torque
requirement: 185 - 200 in./lbs.). Pipe wrenches,
pliers, and adjustable wrenches will damage/round-off
the hex.
4. Securely install the AquaSmart control to the sensor.
Plug the 2-in-1 Sensor RJ connector (phone jack style)
into the receptacle (Item a, Figure 6a) on the control.
5. Route the 36” green wire through the AquaSmart
bottom rectangular slot (Item c, Figure 6a). Securely
install the fork connector of the 36” ground wire and
the ground wire from the 2-in-1 sensor under the
ground screw at the bottom of the control (Item b,
Figure 6a).
6. Thoroughly clean the pipe surface and securely
tighten the pipe clamp on the water inlet pipe to the
boiler as close to the boiler as possible.
7. Route the 36” green ground wire to the pipe clamp
then cut to proper length, if necessary.
8. Strip the wire and insert the stripped end into hole on
the pipe clamp (item d, Figure 6b). Tighten retaining
screw against the wire making sure that you have
good contact.
9. Complete control wiring and fill the appliance with
water to the pressure required, according to appliance
manufacturer’s instructions. Make sure all air is
purged from the system and there are no leaks. Turn
on power to the appliance and observe one call for
heat cycle with shut off at set temperature.
2-in-1 “Replaceable Unit” Instructions
This is very important for successful control operation.
1. Remove the existing immersion well. Clean the
threads in the boiler port tapping. Follow all
applicable safety codes, rules and guidelines for
removing/installing immersion wells.
2. Apply pipe sealant to the 2-in-1 replaceable
thermowell threads and install it securely into the port.
BECKETT RECOMMENDS ONLY TO USE TEFLON
TAPE OR RECTORSEAL NO. 5 PIPE SEALANT.
3. Tighten with 1-1/8” open end or box wrench (torque
requirement: 185 - 200 in./lbs.). Pipe wrenches,
pliers, and adjustable wrenches will damage/round-off
the hex.
4. Insert the sensor probe into the thermowell and push
it completely in until the sensor bottoms out (see
Figure 7). Route the sensor leads through the control
opening (Item h, Figure 6a) and securely install the
control to the thermowell.
5. Plug the 2-in-1 Sensor RJ connector (phone jack
style) into the receptacle (Item a, Figure 6a) on the
control.
6. Route the 36” green wire through the AquaSmart
bottom rectangular slot (Item c, Figure 6a). Securely
install the fork connector of the 36” ground wire and
the ground wire from the 2-in-1 sensor under the
ground screw at the bottom of the control (Item b,
Figure 6a).
7. Thoroughly clean the pipe surface and securely
tighten the pipe clamp on the water inlet pipe to the
boiler as close to the boiler as possible.
8. Route the 36” green ground wire to the pipe clamp
then cut to proper length, if necessary.
9. Strip the wire and insert the stripped end into hole on
the pipe clamp (item d, Figure 6b). Tighten retaining
screw against the wire making sure that you have
good contact.
10. Complete control wiring and fill the appliance with
water to the pressure required, according to appliance
manufacturer’s instructions. Make sure all air is
purged from the system and there are no leaks. Turn
on power to the appliance and observe one call for
heat cycle with shut off at set temperature.
