ELECTRICAL CONNECTIONS
Field connections must comply with national and local codes.
The work must be done by a qualified electrician.
Heater must be permanently grounded and bonded.
Bonding will drastically reduce the chances of electrolysis, “Electrical Corrosion.”
Use copper conductors only.
Disconnect all power sources before performing any work on unit.
Standard Power Supply: 208/230 - 60 – 1
See unit data plate for specific ampacity.
Wiring Main Power Supply
1.
Remove the screws from lower left and right side of front cover (service panel).
2.
Remove the screws on left side of hinged electrical enclosure.
3. Route weather tight flexible conduit through opening at base of unit. Connect conduit to
the bottom of the electrical enclosure using a weather tight fitting. A knockout is provided to
accept the weather tight fitting. Mounting conduit directly to the electrical
enclosure will ensure a moisture tight seal, extending the life of the heater.
4. Attach grounding conductor to the ground lug provided inside the electrical enclosure (labeled).
5. Install L1 and L2 input conductors to the line side of the main contactor. (See wiring diagrams.)
6. Connect bond wire (at least #8 solid copper wire) from bond lug on right side of coil header
panel to pool pump bonding terminal or other suitable location.
Install Heat/Cool Switch
The switch to change from Heating to Cooling is removed from the electrical enclosure after testing at the
factory to prevent damage during shipping. It must be reinstalled in the field at time of installation.
