Heat Controller HSS Series Installation, Operation & Maintenance Instructions Manual page 11

x CAUTION! x
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.

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
Figures 7 and 8. All earth loop piping materials should be
limited to polyethylene fusion only for in-ground sections of
the loop. Galvanized or steel fittings should not be used at
any time due to their tendency to corrode. All plastic to metal
threaded fittings should be avoided due to their potential to
leak in earth coupled applications. A flanged fitting should
be substituted. P/T plugs should be used so that flow can be
measured using the pressure drop of the unit heat exchanger.
