Introduction; Features; Suggestions For Safe Operation - D-D The Aquarium Solution DC750 Product User Manual

INTRODUCTION

Thank you for purchasing a D-D DC series aquarium chiller, which offers an economical and technologically
advanced solution to the cooling of your aquarium.
Excessive temperatures in your aquarium can now be quickly and easily controlled by selecting the correct
model from the D-D DC chiller range, which use a heat exchanger that is manufactured from high-grade pure
titanium, making the chillers suitable for applications in fresh or salt water aquariums.
The system design and high efficiency compressor reduce the forces on the rotor, which results in significantly
lower noise levels, whilst the digital temperature controller ensures that the selected temperature is maintained.
Our chillers use the environmentally friendly R134a refrigerant.
D-D DC series chillers are robust, with a strong chassis and aesthetic, non-corrosive, ABS plastic housing which
ensures that the chiller does not look out of place in any surroundings.

improper use. Failure to do so may result in loss of fish or damage to this unit.
