NOTES:
1. Compressor and blower motor thermally protected internally.
2. All wiring to the unit must comply with NEC and local codes.
3. Transformer is wired to 460 v BLK/RED lead for 460-3-60 units. Trans-
former is energy limiting or may have circuit breaker.
4. FP1 thermistor provides low temperature protection for water. When
using antifreeze solutions, cut JW3 jumper.
5. Refer to microprocessor control, LON, or thermostat installation
instructions for wiring to the unit. Wire “N01” from LON to “Y1” Com-
plete C when a motorized valve is not used. Low voltage wiring must
be Class 1 and voltage rating equal to or greater than unit supply
voltage.
6. Factory cut JW1 jumper. Dry contact will be available between AL1 and
AL2.
7. Transformer secondary ground via green wire with yellow strip from “C”
terminal to control box.
8. Fan motors are factory wired for medium speed. For high or low speed,
remove BLU wire from fan motor speed tap “M” and connect to “H” for
high speed or “L” for low speed.
9. For low speed, remove BLK wire from BR “6” and replace with RED.
Connect BLK and BRN wires together.
10. Optional LON wires. Only connect if LON connection is desired at the
wall sensor.
11. For blower motors with leads. For medium or low speed, disconnect
BLK wire from BR “6”. Connect BLK and ORG/PUR wire together.
Connect RED for low or BLU for medium to BR “6”.
12. Blower motor factory wired to medium speed. For low speed remove
BLU wire from medium tap and connect to low speed tap. For high
speed, remove BLU wire from exisiting speed tap and remove BRN
jumper wire from high speed tap. Connect BLU wire to high speed tap.
Tape off unconnected end of BRN jumper.
13. The 460-v units using an internal secondary pump will require a neu-
tral wire from the supply side in order to feed the accessory with 265-v.
