Multiaqua Chiller Manual
The Multiaqua Chiller System is the only air conditioning/refrigeration system of its kind in
the world today offering the degree of application flexibility described in the following
manual.
The Multiaqua Chiller System is not only unique in its application flexibility; it is unique in
superior quality, rated capacities, and rugged durability. When installed in accordance with
these instructions, the system will deliver years of trouble free service.
Proper equipment sizing, piping design, and installation are critical to the performance of the
chiller. This manual is meant to be a “how to” introduction to piping and installing the
Multiaqua Chiller System.

Website information addresses are supplied throughout this manual for piping and accessory
information. The plumbing industry also has pressure drop information on ferrous and copper
piping systems.
The following sections will describe each component and how it functions within the system.
Installation information is supplied where appropriate. The piping design section will explain
the design and layout the piping system from a “how to” perspective. Following the examples
provided will enable the installer to determine the correct pipe and accessory sizing, as well as
equipment location. It is important to know before installation if the proposed system will
operate correctly. That determination can be made by doing a formal layout of a new
application or a review of an existing piping system.
The chiller circulates a solution of water and Propylene Glycol. Throughout this manual the
term “liquid solution” is used in place of a water and glycol mixture.
It is essential to operate the system with a minimum of 10% glycol, or
more, as required by your climate zone. DO NOT OPERATE THIS
SYSTEM USING WATER ALONE.
For proper liquid solutions mix ratios, refer to page 16 or the glycol
manufacturer’s recommended mix ratios.
