SAFETY
CONSIDERATIONS
Read and follow mmmfacturer instructions cguefully. Fol-
low all local electrical codes during installation. All wiring
must conform to local and national electrical codes, hnproper
wiring or installation may dalnage sensol:
Undel,stand the signal words DANGER, WARNING and
CAUTION. These words gueused with the safety alert symbol.
DANGER identifies the most serious hazards which will result
in severe pel,sonal inju U or death. WARNING signifies a haz-
_ud which could result in personal inju U or death. CAUTION
is used to identify unsafe practices which would result in minor
personal inju U or property damage.
GENERAL
Aquazone Complete C and Deluxe D electronic heat pump
controls are durable, microprocesso>based controllers used to
improve the safety mid operation of Aquazone water source
heat pumps. The microprocessor board is specifically designed
to protect against building electrical system noise contamina-
tion mid radio fiequency interference.
The Complete C control base model is a low cost, easy to
use control that provides all the necessa U features for water
source heat pump safety mid operation. The Complete C
control features a light-emitting diode (LED) to indicate high
pressure, low pressure, low voltage, high voltage, air/water
freeze protection, condensate overflow and control status. The
Complete C control is compatible with most heat pump
thermostats, but is not compatible with Heat/Cool thermostats.
