WARNING: To properly service this equipment, you

mechanical skills, and access to the necessary tools and
equipment. If you do not possess these requirements,
please do not attempt to perform any service on this
equipment except for the procedures recommended in
this manual.
Important installation notes for control
signals wiring:
•
Before performing any electrical installation, make
sure to de-energize the heater.
•
Control wires should be run in a separate conduit to
avoid interference with other wires.
•
Use the grommet/knockouts available in the corner
post to route wires into the heater. Ensure that liquid-
tight connectors are used to prevent water or dust
intrusion.
•
Low voltage wiring should not be run together with
high voltage lines.
•
Use the appropriate relays for your application,
ensuring that the relay coil is compatible with the
external power supply. For the single-speed pump
output, use a 24VAC relay.
•
Use the supplied accessory harness to connect to
terminals P4, P5, P7, P8, P9, and P11 on the heater.
1. Before starting any work on the unit, make sure to
shut off all power to avoid the risk of electrical shock or
damage to components.
2. To access the heater's front control cover panel, use
a 1/4" hex head screwdriver to unscrew the six (6)
screws. See Figure 125.
