CAUTION
To prevent potential damage to heat exchanger, always run
fluid through heat exchanger when adding or removing
refrigerant charge. Use appropriate brine solutions in cooler
fluid loop to prevent the freezing of brazed plate heat
exchanger, optional hydronic section and/or interconnecting
piping when the equipment is exposed to temperatures
below 32 F (0° C). Proof of flow switch and strainer are
factory installed on all models. Do NOT remove power
from this chiller during winter shutdown periods without
taking precaution to remove all water from heat exchanger
and optional hydronic system. Failure to properly protect
the system from freezing may constitute abuse and may
void warranty.
CAUTION
Compressors and optional hydronic system pumps require
specific rotation. Test condenser fan(s) first to ensure
proper phasing. Swap any two incoming power leads to
correct condenser fan rotation before starting any other
motors.
CAUTION
Refrigerant charge must be removed slowly to prevent loss
of compressor oil that could result in compressor failure.
CAUTION
Puron refrigerant (R-410A) systems operate at higher
®
pressures than standard R-22 systems. Do not use R-22 ser-
vice equipment or components on Puron refrigerant equip-
ment. If service equipment is not rated for Puron
refrigerant, equipment damage or personal injury may
result.

GENERAL

This publication contains Controls, Start-Up, Operation,
Service, and Troubleshooting information for the AquaSnap

Conventions Used in This Manual —
ing conventions for discussing configuration points for the
local display (scrolling marquee or Navigator™ accessory)
will be used in this manual.
Point names will be written with the mode name first, then
any sub-modes, then the point name, each separated by an
arrow symbol (. Names will also be shown in bold
and italics. As an example, the Lead/Lag Circuit Select Point,
which is located in the Configuration mode, Option sub-mode,
would be written as Configuration OPT2LLCS.
This path name will show the user how to navigate through
the local display to reach the desired configuration. The user
would scroll through the modes and sub-modes using the
and keys. The arrow symbol in the path name repre-
sents pressing to move into the next level of the
ENTER
menu structure.
When a value is included as part of the path name, it will be
shown at the end of the path name after an equals sign. If the
value represents a configuration setting, an explanation will
be shown in parenthesis after the value. As an example,
ConfigurationOPT2LLCS = 1 (Automatic).
Pressing the
will scroll an expanded text description of the point name or
value across the display. The expanded description is shown in
the local display tables but will not be shown with the path
names in text.
The CCN (Carrier Comfort Network
referenced in the local display tables for users configuring the
unit with CCN software instead of the local display. The CCN
tables are located in Appendix B of the manual.
