Two Stage Geothermal Heat Pump Systems

Features of the Two Stage HT Series

The HT Series Geothermal Heat Pumps are some of the most efcient and innovative geothermal units on the market today.

Packed with features, they offer the best value to the homeowner who is interested in quiet comfort and low operating costs

as a result of extraordinary efciencies.

Technically, the HT Series are state-of-the-art with digital electronic controls, multi-stage scroll compressors, computer

controlled fan motors, zero ozone depleting refrigerant, and much more.

Design Features

• Five capacities to meet all application requirements—two,

three, four and six ton models.

• Efcient operation from 20°F to 120°F entering water tempera-

tures. Flow rates may be as low as 1.6 gpm/ton.

• Top supply air discharge accommodates upow applications.

• Select left or right hand return air positions for all models;

cabinets include a deluxe lter rack/duct collar.

• Variable speed ECM blower motor adjusts to multiple duct

system applications and provides soft start for added comfort

and quiet operation.

• Narrow cabinet design can be easily moved through doorways.

• Internally trapped condensate piping (on all vertical units)

allows easy, compact installation.

• Internal electric heat unit (optional) is designed for easy eld

installation.

• Electric box is positioned for easy eld wiring from two sides.

• Loop pump power block is built with circuit breaker.

• Coaxial low temperature protection can be selected in the eld

for well or closed loop installations.

• Air coil low temp. protection utilizes high accuracy thermistors.

• Coaxial heat exchanger, refrigerant suction lines, hot water

generator coil, and all water pipes are fully insulated to reduce

condensation in low temperature conditions.

• Isolation mounted compressors and low RPM blowers are used

to reduce noise; compressor compartment and interior cabinet

are insulated with 1/2" coated glass ber insulation.

• Double isolated compressor delivers extra quiet operation.

• Safety features include: high pressure and loss of charge pro-

tection for the compressor; condensate overow protection; low

temperature protection sensors to safeguard the coaxial heat

exchanger and air coil; hot water high-limit hot water genera-

tor pump shutdown; fault lockout that enables emergency heat

and prevents compressor operation until thermostat or circuit

breaker has been reset.

Operating Efciencies

• AHRI/ASHRAE/ISO 13256-1 ratings for heating COPs and

cooling EERs are industry leaders.

• Hot water generator (HWG) with internal pump generates hot

water at dramatic savings while improving system performance.

• Efcient scroll compressors provide quiet, reliable operation.

• Oversized coaxial tube water-to-refrigerant heat exchanger

delivers high efciency and extra heating capacity; convoluted

water tube functions efciently at low ow rates and provides

resistance to freeze damage.

• Oversized ried copper tube/lanced aluminum n air-to-refriger-

ant heat exchanger offers high efciencies at low air velocity.

• Large, low RPM blower is both quiet and efcient, and provides

high static capability.

Service Advantages

• Three removable access panels for the compressor compartment

and one or two (depends on model) for the air handler compart-

ment offer quick access to all internal components even with

ductwork in place, making the unit service-friendly.

• Built with bi-directional thermal expansion valve.

• Brass, swivel water connections make it easy to connect loop

and hot water piping.

• Insulated divider and separate air handling/compressor access

panels allow service testing without air bypass.

• Design allows in-place service in tight installation spaces.

• CXM control features LED status light with memory feature for

easy diagnostics.

• Control box and fan motors have quick-attach wiring connections

for fast removal/reconnection.

• Biow liquid line lter drier is factory-installed.

• 75 VA control transformer comes with circuit breaker.

• Internal drop-out blower assemblymakes servicing simple.

• Refrigerant circuit includes high and low pressure service ports.

• E-coated refrigerant-to-air coil helps protect the coil from

corrosion and extends life expectancy.

Factory Quality

• All units are built using our state-of-the-art manufacturing system

that is designed to assure quality of the highest standards. This

system:

-Veries that the correct components are being assembled;

-Automatically performs special leak tests on all joints;

-Conducts pressure tests;

-Performs a highly detailed run test;

-Automatically prevents a "failed" unit from being packaged for

shipment;

-Creates a computer database of run tests for future service

analysis and diagnostics;

-Includes painting heavy gauge steel cabinets with durable epoxy

for a long-lasting nish;

-Performs all refrigerant brazing in a nitrogen-rich environment;

-Evacuates units to a deep vacuum of less than 50 microns

prior to refrigerant charging

-Halogen leak tests all joints to ensure a leak rate of less

than 1/4 ounce per year.

Options & Accessories

• Optional internal auxiliary electric heat.

• Electronic auto-changeover thermostats with indicator LEDs.

• Closed loop ow controller and hose kits.

ELECTRICAL - LINE VOLTAGE

All eld installed wiring, including electrical

ground, must comply with the National

Electrical Code as well as all applicable

local codes. Refer to the unit electrical

data for fuse sizes. Consult wiring diagram

for eld connections tKat must be made by

the installing (or electrical) contractor. All

nal electrical connections must be made

with a length of exible conduit to minimize

vibration and sound transmission to the

building.

GENERAL LINE VOLTAGE WIRING

Be sure the available power is the same

voltage and phase shown on the unit serial

plate. Line and low voltage wiring must be

done in accordance with local codes or the

National Electric Code, whichever is

applicable.

WARNING! To avoid possible injury

or death due to electrical shock, open

the power supply disconnect switch

and secure it in an open position

during installation.

WARNING! 

CAUTION! UseRnly copper

conductors for eld installed electrical

wiring.Unit terminals are not

designed to accept other types of

conductors.

EAT in cooling and 68°F DB / 59°F WB EAT in heating.

Interpoaltion is permissable, extrapolation is not.

All entering air conditions are 80°F DB and 67°F WB in cooling and 70°F DB in heating

All performance data is based upon the lower voltage of dual voltage rated units

See performance correction tables for operating conditions other than those listed above.

Operation below 60°F EWT requires optional insulated water circuit.

Operation below 40°F EWT is based upon 15% antifreeze solution.
