ELECTRICAL INSTALLATION
This equipment system has been100% factory tested for quality and reliability prior to
shipping. Care should be taken on all electrical connections to avoid damage to the system
circuit board, and added components. Damage caused by accidents, improper wiring
configurations and/or abuse voids your warranty.
Start by having your electrician select a wiring configuration that best fits your total system
needs. (see the GFCI breaker sizing matrix on page 8)
Due to the availability of GFCI breaker sizes, and your electrical supply requirement, some
systems require a second independent or “dual” power source, to supply the electric heater
separately. Diagrams for independent heater wiring are provided in this manual.
Note; 5.5kw systems using a single source power supply will not allow electric heater
operation when pumps are in high speed. See system programming to change operation if
available.

All Hydro-Quip 8000 series control systems require a 4 wire electrical supply, incorporating
a “Neutral” wire for operation. Electric heaters being powered independently in the “dual”
circuit configuration do not require a neutral wire supply. This is clearly explained in the
wiring diagrams.
For gas heaters electrical connection, consult your gas heaters supplier manual, and note
in this manual contains important wiring instructions for control and operation of the gas
heaters fireman circuit.
Gas and electric heater combination
When faster heat recovery is desired, or a redundant heat source is a priority, it’s possible
to install both a gas and electric heater on the same 8000 series system.
Default programming allows both the gas heater control circuit (page 15) and electric
heater circuit to operate simultaneously. Input from both heat sources will speed up heating
times, and also provide an operating alternate if one source becomes disabled. You must
follow all installation instructions for both the gas heater, and electric heater plumbing and
wiring requirements to successfully connect. No PCB programming change is required.
