Introduction To Econar Heat Pumps; Unit Location/ Mounting; Duct System/Blower - Econar GeoSource 2000 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 onergy 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
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 efhcient fossil
fuel
systems.
ECONAR produces
three types
of
GeoSource 2000
heat
pumps: forced air
heat
pumps, which
transfer heat
from
water to air; hydronic heat
pumps, which
transfer heat
from
water to water;
and
combination heat
pumps, which
incorporate
the
hydronic heating of
a
water to water
unit
into aforced air
unit.
This guide
discusses the
forced air
unit.
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
being gas free.
The
best
engineering
and
quality confrol
is
built
into
every
ECONAR
heat pump
built.
Proper application
aad
correct
installation
will
assure
excellent performaace
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
per{ormance 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 of refrigerant
based
equipment
can be hazardous
due
to system pressure
nd
230 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
al1
local
electrical,
plumbing,
heating
and air
conditioning
codes
are
followed.
II.
UNIT LOCATION/
MOUNTING
Locate
the
unit in
an
indoor
area
where
the
arnbient
temperature
will
remain
above
451F.
Servicing
of
the
heat
pump is
done
primarily from
the
front.
Rear
access
is desirable and should be
provided when possible.
A
field installed drain 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
transportation or installation, or
severe
internal
damage
may occur.
Units
must be
mounted
on a
vibration-absorbiag 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 alI 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
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 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
and
to
absorb noise.
If
the unit is
connected
to existing ductworh
this
ductwork must
have the capacity to handle the
air
volume
required by
the heat
pump.
Undersized duct
work
will
cause
noisy operation
and
poor operating efficiencies
due
to lack of
affiow.
The GeoSource 2000 forced air
heat
pumps
use
a
230
Volt
three
speed
blower.
For
maximum airflow,
