Introduction To Econar Heat Pumps; Unit Location/Mounting - Econar GeoSource Vara 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 what 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
coolilg,
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 hoat
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.
This guide
discusses the GeoSource
Vara
series heat
pumps that
are equipped
with
a
variable
speed
Electronically
Commutated
Blower Motor (ECM)
to
provide
three speeds
of
air
ouput,
depending on the
operating mode
of
the heat
pump.
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
of beiag
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
full
run
test
where
the
performance and
operation is verified in
the
heating, cooling,
and
hot
water
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
systempressure
and230 volt electrical
energy.
Only trained
or qualified
service
personnel
can
install,
repair or service refrigerant equipment.
I
Warning:
Tum
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.
II.
UNIT LOCATION/
MOUNTING
Locate the
unit
in
an
indoor
area where the ambient
temperature
will
remain
above
45T.
Servicing
of
the
heat
pump is
done
primarily from
the
front.
Rear
access
is desirable and should be
provided when
possible. A
field
installed draia pan
is required under
the entire
unit
where accidental water discharge could damage
surrounding
floors, walls
or ceilings.
VCAUTION -
Do not tip units on their
side during
fransportation or
installation, or
severe
intemal
damage
may 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.
eNote:
Keep all doors and screws installed on
unit
while moving unit
and
installing ductwork. This
will
help
ensure
that the
unit
stays square,
allowing for
easier
removal
of
door 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.
rI.
DUCT SYSTEM/BLOWER
For
the duct system,
metal ductwork
should be
used.
Flexible connectors
are
required for discharge
and
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,
absorb
noise,
and
prevent condensation
from collecting on
the
ductwork.
If
the
unit
is connected to existing
ductwork,
this
ductwork
gq!
have the
capacity to handle
the
air volume
required
by
the heat
pump.
Undersized
ductwork
will
cause
noisy operation and
poor operating efficiencies
due
to lack
of airflow.
