WARNING: Disconnect primary power prior to servicing.
Section 2 Installation
Maxiva ULX COFDM Series
NOTE:
Condensation can occur in the conduits connecting the heat exchanger (outside)
and the transmitter (inside). These conduits should be caulked or sealed after the
system is tested and operational. Sealing the conduit prevents warm air inside the
building from entering the portion of the conduit that is located outside the build-
ing.
STEP 5
Connect the control and status wires to connector J1 on the
customer I/O panel (located at the top of the transmitter) with the
supplied multi-conductor cable.
These low level signals, outlined in
Table 2-6, connect from terminals inside the pump module control panel
to J1-1 through J1-12 (see Figure 2-3), on the pump module connector at
the customer I/O panel on top of the transmitter.
