Subject to change without prior notice
Fouling due to iron bacteria can also pose
problems in some open loop installations. Iron
bacteria fouling can quickly degrade system
performance and plug heat exchangers.
Air in the water system will greatly accellerate the
fouling or corrosion process.
INSTALLATION
The following are instructions to follow for
installation of all LV Series components.
Duct Flanges
LV heat pumps feature fold-out return and supply
air duct flanges. These fold-out flanges allow the
heat pumps to more easily fit through doorways
and other tight spaces, and also prevent damage in
shipping and handling.
It is recommended that all fold-out flanges be
folded-out once the heat pump is installed to
insure that return and supply air flow is not
obstructed. These flanges can be easily folded
using standard or duckbill pliers. Once folded out
these flanges can be used to support light
ductwork loads.
