Ground-Loop Heat Pump Applications
ѥ
CAUTION!
ѥ
Pre-Installation
Prior to installation, locate and mark all existing underground
utilities, piping, etc. Install loops for new construction before
sidewalks, patios, driveways, and other construction has
begun. During construction, accurately mark all ground loop
piping on the plot plan as an aid in avoiding potential future
damage to the installation.
Piping Installation
The typical closed loop ground source system is shown in
Figure 7. All earth loop piping materials should be limited
to polyethylene fusion only for in-ground sections of the
loop. Galvanized or steel
Ä
ttings should not be used at any
time due to their tendency to corrode. All plastic to metal
threaded
Ä
ttings should be avoided due to their potential to
leak in earth coupled applications. A
Å
anged
Ä
tting should
be substituted. P/T plugs should be used so that
Å
ow
can be measured using the pressure drop of the unit heat
exchanger.

CAUTION!
The following instructions represent industry
accepted installation practices for closed loop earth
coupled heat pump systems. Instructions are provided
to assist the contractor in installing trouble free ground
loops. These instructions are recommendations only.
State/provincial and local codes MUST be followed and
installation MUST conform to ALL applicable codes. It is
the responsibility of the installing contractor to determine
and comply with ALL applicable codes and regulations.
