Multiaqua Heat Pump 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
capacity 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.
RECOGNIZE THIS SYMBOL AS AN INDICATION OF IMPORTANT SAFETY OR
INSTALLATION RELATED INFORMATION.
Pressure loss information for a Composite Piping System has been used in preparing this manual. Web site 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, which will vary from the composite pipe system outlined
in this manual. Composite pipe is the recommended pipe for Multiaqua Chiller System installations; however existing
piping systems can be adapted to the system.
The following sections will describe each component, and how it functions within the system. Installation information
is supplied where appropriate. The piping design section ( page 26) will explain the design and layout out of 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, and doing a formal layout of a new application or review of an existing piping system will
make that determination.
Throughout this manual the term
liquid solution
is used in place of water. The chiller circulates a solution of water
and Propylene Glycol.
It is essential to operate the system with a minimum of 10% propylene glycol.
DO NOT OPERATE THIS SYSTEM USING WATER ALONE!
FOR PROPER LIQUID SOLUTIONS MIX RATIOS, REFER TO PAGE 6 OR THE GLYCOL
