Introduction To Econar Heat Pumps; Il Unit Location/Lvlounting; Duct System/Blower - Econar GeoSource DualTEK GV Series Installation And Operating Instructions Manual

I. INTRODUCTION TO
ECONAR HEAT
PUMPS
ECONAR
Energy
Systems,
Corp.
has been
producing
geothermal
heat pumps in Minnesota for
over
fifteen
years.
The cold winter climate
has
driven
the design
of
ECONAR
Energy
System's
heating
and
cooling
equipment to
uhat is
known
as a
"Cold Climate"
geothermal
heat
pump.
This cold climate technology
focuses on maximizing
the
energy
savings
available in
heating dominated regions without sacrificing
comfort-
Extremely efficient cooling, dehumidification
and
optional domestic hot water heating
are also
provided
in
one
neatly packaged
system.
Geothermal heat pumps get their
name
from
the transfer
of
heat
to
and
from
the
earth.
The earth coupled
heat
exchanger (geothermal loop)
supplies
the source
energy
for
heating
and absorbs the
discharged energy from
cooling.
The
system
uses a
compression cycle, much
like
your refrigerator, to collect
the earth's energy supplied by
the sun and
uses
it
to
heat
your home.
Since the process
only
moves heat and does not
create
it,
the
efficiencies
are
three to
four
times higher
than the
most efficient fossil
fuel
systems.
ECONAR produces
three types
of geothermal heat
pumps: forced air
heat
pumps,
which
transfer
heat
from
water to air;
hydronic heat
pumps, which transfer
heat
from water to water;
and GeoSource
DualTEK
heat
pumps,
which incorporate
the
hydronic heating of
a water
to water unit into
a
forced air
unit.
This guide
discusses
the
GeoSource
DualTEK
unit (U.S.
Patent Number
4,8s6,878).
Safety and
comfort
are
both inherent to, and designed
into
ECONAR
Energy
System's
geothermal
heat pumps.
Since the system
runs completely
on electrical energy,
your
entire home
can have the
safety
ofbeing
gas
free.
The
best engineering and
quality control
is
built
into
every
ECONAR
heat
pump
built.
Proper application
and
correct
installation
will
assure
excellent performance
and
customer satisfaction.
ECONAR's
commitment to
quality
is written on
the side
of
every heat pump we
build.
Throughout
the
building
process the technicians that build
each
unit
sign their
names to the
quality
assurance label after completing their
inspections.
As
a
final quality
test, every
unit
goes
through
a
fulI
run
test where the
performance and
operation is verified
in both the heating
and
cooling
modes. No
other manufacturer
goes
as
far
as
to run
a
full
performance check to
assure system
quality.
**
IMPORTANT**
Service ofrefrigerant
based equipment
can be hazardous
due
to
system
pressure
and 230
volt
electrical energy.
Only
trained
or qualified
service personnel
can
install,
repair or service refrigerant equipment.

I
Warning
- Turn offthe
main switches before
performing
service or
maintenance
to this
unit.
Electrical
shock can cause personal
injury.
The installer
is
responsible to
see
that
all local
electrical,
plumbing,
heating
and
air conditioning
codes are followed.
aNote:
The
Hydronic
side
of
the GeoSource
DualTEK
utilizes
a single-walled heat exchanger,
and is
not
intended
for
use
with potable water.
II.
UNIT LOCATION/
MOUNTING
Locate
the
unit in
an
indoor
area
where
the
ambient
temperature
will
remain
above
45oF. Servicing of
the
heat
pump is
done
primarily from
the
front.
Rear
access
is
very desirable
and
should
be
provided
when
possible.
A field
installed drain pan is required under
the enrire
unir
where accidental water discharge could
damage
surrounding floors, walls or ceilings.
VCAUTION
-Do
nor
tip
units
on
rheir
side
during
transportation or installation, or
severe internal
damage
rr[ry occur.
Units
must be mounted on
a
vibration-absorbing pad
slightly
larger than
the base
to provide isolation between
the
unit
and the
floor.
Water supply pumps should not
be
hard
plumbed directly
to
the
unit with copper pipe; this
could transfer vibration from
the
water pump to
the
refrigeration circuit,
causing
a
resonating sound. Hard
plumbing
could also transfer
vibration
noise from
the
unit
through the
piping
to
the
living
space"
cNote:
Keep
all
doors and screws installed
on the
unit
while moving
the
unit
and
installing ductwork.
This
will
help
ensure that the
unit
stays square, allowing for
easier
removal
of
the
doors after
the
ductwork
is attached.
VCAUTION
- Before
driving
screws
into
the
cabinet,
check on the
inside of
the
unit
to
be sure
the
screw
will
not
hit
electrical
or
refrigeration
lines.
III.
DUCT SYSTEM/BLOWER
For
the
duct
system,
metal ductwork
should
be used.
Flexible connectors
are
required
for
discharge ard return
air duct connections on
a
metal duct system. For
acceptable
duct
sizes,
see
Table
1.
Ifthe
duct
system
is installed in
an uninsulated
space, the
metal ductwork
should be insulated on
the
outside to
prevent
heat
loss
and
to
absorb noise.
If
the
unit
is
connected
to existing ductwork,
this
ductwork
must
have the capacity to handle the air volume
required by
the heat
pump.
Undersized
ductwork
will
f
