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 460/60/3 units,
575 v (GRY) lead for 575/60/3. Transformer is energy limiting or may
have circuit breaker.
4. FP1 thermistor provides freeze protection for water. When using anti-
freeze solutions, cut JW3 jumper.
5. Check installation wiring information for specific thermostat hookup.
Refer to thermostat installation instructions for wiring to the unit.
Thermostat wiring must be "Class 1" and voltage rating equal to or
greater than unit supply voltage.
6. 24-v alarm signal shown. For dry alarm contact, cut JW4 jumper and
dry contact will be available between AL1 and AL2.
7. Transformer secondary ground via Deluxe D board standoffs and
screws to control box. (Ground available from top two standoffs as
shown.)
8. Aquastat is supplied with unit and must be wired in series with the
hot leg to the pump. Aquastat is rated for voltage up to 277 v.
9. Blower motor is factory wired for high and low speeds. No other com-
bination is available.
10. The 460-v units using an ECM (electronically commutated motor) fan
motor, modulating HWR, and/or an internal secondary pump will
require a neutral wire from the supply side in order to feed the acces-
sory with 265-v.
