Section 2: Installation Introduction

Introduction

This geothermal heat pump provides heated water and chilled 
water as well as optional domestic water heating capability. 
Engineering and quality control is built into every geothermal 
unit. Good performance depends on proper application and 
correct installation.

Notices, Cautions, Warnings, & Dangers:

“NOTICE” Notification of installation, operation or 
maintenance information which is important, but which is NOT 
hazard-related.

“CAUTION” Indicates a potentially hazardous situation or an 
unsafe practice which, if not avoided, COULD result in minor or 
moderate injury or product or property damage. 

“WARNING” Indicates potentially hazardous situation which, if 
not avoided, COULD result in death or serious injury.  

“DANGER” Indicates an immediate hazardous situation which, 
if not avoided, WILL result in death or serious injury.  

Inspection

Upon receipt of any geothermal equipment, carefully check 
the shipment against the packing slip and the freight company 
bill of lading. Verify that all units and packages have been 
received. Inspect the packaging of each package and each unit 
for damages. Insure that the carrier makes proper notation of 
all damages or shortage on all bill of lading papers. Concealed 
damage should be reported to the freight company within 15 
days. If not filed within 15 days the freight company can deny 
all claims.

Note: Notify Enertech Global, LLC shipping department of all 
damages within 15 days. It is the responsibility of the purchaser 
to file all necessary claims with the freight company.

Un-packaging 

Enertech units are mounted to wooden pallets for easy 
handling during shipment and installation. Units are protected 
during shipment with durable cardboard corner posts, top and 
air coil panels. Shrink wrap is applied covering the entire unit 
and attachment to the pallet.

Upon receipt of the unit carefully remove the shrink wrap. 
Using a box cutter slit the shrink wrap on the cardboard top 
and corner posts. Use caution to not damaged the finished 
surface of the unit. Keep all cardboard or other packaging 
material for safe storage and transport to the job site prior to 
installation. 

Remove the front compressor section service panel to locate 
technical documents; manuals, bulletins or instructions and 
accessory items; HWG piping kits, supply/return duct flange 
kits or condensate tubing kits prior to installation.

⚠ 

CAUTION 

Do not operate the geothermal heat pump unit during 

building construction phase.

Unit Protection

Protect units from damage and contamination due to 
plastering (spraying), painting and all other foreign materials 
that may be used at the job site. Keep all units covered on 
the job site with either the original packaging or equivalent 
protective covering. Cap or recap unit connections and all 
piping until unit is installed. Precautions must be taken to 
avoid physical damage and contamination which may prevent 
proper start-up and may result in costly equipment repair.

Storage

All geothermal units should be stored inside in the original 
packaging in a clean, dry location. Units should be stored in 
an upright position at all times. Units should not be stacked 
unless specially noted on the packaging.

Removal and Disposal

All Geothermal units removed from service should have 
all components, oils, antifreeze and refrigerants properly 
disposed of according to local and national environmental 
recycling codes, regulations, standards and rules.

Pre-Installation

Special care should be taken in locating the geothermal unit. 
Installation location chosen should include adequate service 
clearance around the unit. If units are being placed on racking, 
the unit must be placed on a solid foundation. All units should 
be located in an indoor area where the ambient temperature 
will remain above 55°F and should be located in a way that 
piping and ductwork or other permanently installed fixtures do 
not have to be removed for servicing and filter replacement.
