Power Wiring
Connect line power to the power terminal block’s L1, N, and PE terminals
(Figure 1.6
). Refer to Table 1.E for power terminal specifications.
Important: The heat exchanger is configured and shipped for 120 VAC
operation. However, its configuration can be changed to
operate on 230 VAC. For details, see Configuring for 230 VAC
Operation on page 1-10.

Configuring for 230 VAC Operation
1. Open the cover of the electrical box (Figure 1.1
) and set the J2 jumper on
the control board (Figure 1.7
) to the 230 VAC position (terminals 1-7).
2. On the power terminal block (Figure 1.6
), disconnect wire #3 from
terminal H2 and reconnect it to terminal H4 for 230 VAC operation.
3. Remove the heat exchanger’s top panel first and then its left side panel to
access the pump motor conduit box. Remove the conduit box cover and
