Installation Precautions
1
-
Make sure the system pack is powered Off at
the GFCI or circuit breaker before starting the
installation process.
2
- These instructions apply to system packs with one
of the following agency prefixes: BP20, BP21, BP501,
BP6. The agency prefix is noted on the system pack
identification label (view page 2).
3
- The M7 temperature sensor connector has a
locking tab (A). Depress the tab before disconnecting
the sensor from the circuit board. When installing
the new heater, make sure the locking tab is
aligned properly with the circuit board connector.
Misalignment may cause damage. The connectors are
small, so a flashlight and magnifying glass can help
with alignment.
4
- The third temperature sensor switch connector has
alignment tabs (E). Make sure the tabs are aligned
properly with the circuit board connector.
Misalignment may cause damage.
The connectors are small, so a flashlight and
magnifying glass can help with alignment.
5A
- Find J29 on the wiring diagram (H). The wiring
diagram is on the inside surface of the system pack
cover. J29 may be at the bottom right of the diagram
of the board, or more toward the bottom center
of the board.
5B
- Confirm that on the wiring diagram “HTR DISBL”
or “HTR DSBL” is written near J29 ( I ). It may be
above or below the “J29” text and may be on the
same side of the jumper picture or on the other side
of the jumper picture. If “HTR DISBL” or “HTR DSBL”
(abbreviations for Heater Disable) is not near J29, then
the 3S heater is incompatible with this system pack.
5C
- If something is already connected to J29,
please contact our technical support at
6
- Each connector is labeled on the system pack circuit
board. The text is small, so a flashlight and magnifying
glass can help with identification.
7
- Do not bump or bend the heater posts.
8
- Do not pull or apply unnecessary pressure
to the heater connector wires.
