Section 9: Unit Placement
UNIT PLACEMENT:
When installing a geothermal heating and
cooling unit, there are several items the installer
should consider before placing
the equipment.
1. Service Access. Is there enough space for
service access? A general rule of thumb is
at least 2 feet in the front and 2 feet on at
least one side.
2. Unit Air Pad. All vertical geothermal
heating and cooling equipment should be
placed on either a formed plastic air pad,
or a high density, closed cell polystyrene
pad. Downfl ow units should be placed
on a non-combustible base. This helps
eliminate vibration noise that could be
transmitted through the fl oor.
3. The installer has verifi ed that all applicable
wiring, ductwork, piping, and accessories
are correct and on the job site.
PRE-INSTALLATION:
Before you fully install the geothermal
equipment, it is recommended you go
through this quick checklist before placing the
equipment.
୵ Fully inspect the unit after unpacking.
୵ Open both the air handler section and
compressor section and removed any
packaging material or documentation
included in the unit.
୵ Remove all packaging materials and
brackets from the rear of the blower.
୵ Locate the Unit Start-Up form from this
manual and have it available as the unit
installation proceeds.
୵ Clean the air coil with soap and water
solution to remove any oil or dirt.
঑WARNING ঑
DOWNFLOW UNITS REQUIRE THAT THE
FLOOR OPENING (BETWEEN THE UNIT AND
THE SUPPLY DUCT PLENUM) BE SLEEVED
THROUGH THE FLOOR WITH METAL DUCT.
THIS IS ESPECIALLY IMPORTANT IF THE UNIT
IS SITTING ON A PAD.
঑NOTICE ঑
THE BLOWER SUPPORT BRACKET,
LOCATED ON THE BACK OF THE BLOWER
FOR SHIPPING PURPOSES, MUST BE
REMOVED BEFORE OPERATION. FAILURE
TO REMOVE THE BRACKET COULD RESULT
IN POTENTIALLY NOISY OPERATION AND
EQUIPMENT DAMAGE.
঑NOTICE ঑
THIS UNIT FEATURES A BRAZED-PLATE
HEAT EXCHANGER FOR HYDRONIC
HEATING. TO PREVENT POTENTIAL
EQUIPMENT DAMAGE, A WATER STRAINER
IS PROVIDED AND MUST BE INSTALLED IN
THE WATER INLET CIRCUIT TO PROTECT
THE HEAT EXCHANGER FROM PARTIAL
OR COMPLETE BLOCKAGE. IF ANOTHER
STRAINER IS USED, IT SHOULD FEATURE A
16-20 MESH MINIMUM, 20-40 MESH IS A
BETTER CHOICE.
