Removing the Heater Assembly from a BP Spa System
Note: Be careful when removing a heater assembly from
a spa plumbing system. Water may splash out under
pressure.
Water under pressure in the plumbing may splash out, and onto
the system’s electronic board. Do not remove the system door
until the water has been drained from the heater assembly
housed in the system.
Turn off the main power. 1.
Close off the 2. slice valves (or, ball valves) adjacent to the
heater assembly.
Once the valves are closed, slowly crack the heater 3.
assembly end tubes until water flows out. If the connectors
are on too tight, it may be necessary to loosen the Phillips
screws that hold the connectors together. Once the water
has been drained, continue.
Remove the system door cover. 4.
Remove the nuts securing the 5. heater wires to the heater
assembly’s terminal connectors. Be sure to use a
supporting end wrench on the lower nut. (Upper nut is
3/8"; lower nut is 1/4".) If a lower end wrench is not used to
hold the terminal in a fixed position when removing and
installing the upper nut, excessive torque will transfer
to the terminal connector. The result will most likely be a
damaged terminal.
Remove the 6. heating assembly sensor wires and replace if
necessary.
Remove both 3/8" nuts that secure the element in place. 7.
Remove the heater assembly. 8.
Reverse the procedure to reinstall the heater assembly. 9.
Note: Installation of the heater terminal nut is 30 - 35 in lbs.
torque.
Remove both nuts that secure
the element in place.
Locking nuts are in the same
location on other BP models
Avoid damaging the post. Use an end
wrench on the lower nut to reinforce the
post when removing the upper nut.
