Refrigerant
Load and Source Piping Connections
Premium H products all feature zero ozone depletion and low
global warming potential R-410A refrigerant.
The HT has two connection options available. Each kit is intended to
connect one piping connection. Therefore, two kits will be required
for each unit. The kits can be mixed for installer convenience, one on
source and the other on load.
Cabinet
All units are constructed of corrosion resistant galvanized sheet
metal with silver metallic powder coat paint rated for more than
1000 hours of salt spray. Large lift-out access panels provide
access to the compressor section from four sides. Back or top
water connection option is available.
CKNDW1 - Strainer Connection Kit includes a 2” copper tee with
integral P/T plug and a 2” “Y” strainer. Other components to complete
the all copper piping can be sourced locally.
HHK162S - Strainer Hose Kit set includes 2” Hose kit includes a 2”
stainless steel braided hose with integral P/T plug and 2” “Y” strainer.
Compressors
High efficiency R-410A scroll compressors are used on every model.
Scrolls provide both the highest efficiency available and great
reliability.
Electrical Box
Unit controls feature quick connect wiring harnesses for easy
servicing. Separate knockouts for low voltage, and two for power
on two sides allow easy access to the control box. A large 75VA
transformer assures adequate control's power for accessories.

featuring several innovations. See Premium H Controls section for
more information.
HHK162S
CKNDW1
Strainers
All units shall have a field-installed 2" Y-strainer
with a self-aligning screen and 1" blow-off port
to reduce debris that will enter the condenser/
evaporator. Strainers should be made of a
brass body with a 316 stainless steel 20-40
mesh screen.
Water Connections
Flush mount FPT water connection fittings allow one wrench leak-free
connections and do not require a backup wrench. Factory installed
thermistors are used on all water lines and can be viewed through the
microprocessor interface tool.
WARNING: Warranty is void if strainers are not used
on the entering side of the load and source.
Thermostatic Expansion Valve
All Premium H models utilize a balanced
port bi-directional thermostatic expansion
valve (TXV) for refrigerant metering. This
allows precise refrigerant flow in a wide
range of entering water variation (20 to
120°F [-7 to 49°C]) found in geothermal
systems. The TXV is located in the
compressor compartment for easy access.
Service Connections and
Serviceability
Two Schrader service ports are provided for
each circuit on every unit. The suction side
and discharge side ports are for field charging
and servicing access. All valves are 7/16” SAE
connections.
Water-to-Refrigerant Heat Exchanger
Large oversized stainless steel interlaced
copper-brazed plate water-to-refrigerant heat
exchangers provide unparalleled efficiency. The
heat exchangers have common water circuits with
isolated refrigerant circuits so that in part load
operation, the full mass of the heat exchanger is
utilized. All heat exchangers are pressure rated
to 450 psi water side and 650 psi refrigerant side.
All heat exchangers, water lines, and suction lines
are insulated to prevent condensation during low
temperature inlet water operation.

reversing valve. The reversing valve operation is limited to change of
mode by the control to enhance reliability.
The optional GeoStart single
phase soft starter will reduce the
normal start current (LRA) by 6070%. This allows the heat pump
to go off-grid. Using GeoStart
also provides a substantial
reduction in light flicker, reduces
start-up noise, and improves the
compressor's start behavior. GeoStart is available in a field retrofit
kit or as a factory installed option for all Premium H and QT Series
units.

Water Quality
General
exchanger is required. Failure to supply a secondary heat exchanger
where needed will result in a warranty exclusion for primary heat
exchanger corrosion or failure.
HT systems may be successfully applied in a wide range of
residential, commercial, and industrial applications. It is the
responsibility of the system designer and installing contractor to
ensure that acceptable water quality is present and that all applicable
codes have been met in these installations.
Strainers
These units must have properly sized strainers upstream of both
brazed plate heat exchangers to protect them against particles in the
fluid. Failure to install proper stainers and perform regular service
can result in serious damage to the unit, and cause degraded
performance, reduced operating life and failed compressors. Improper
installation of the unit (which includes not having proper strainers to
protect the heat exchangers) can also result in voiding the warranty.
Water Treatment
Do not use untreated or improperly treated water. Equipment
damage may occur. The use of improperly treated or untreated water
in this equipment may result in scaling, erosion, corrosion, algae or
slime. The services of a qualified water treatment specialist should
be engaged to determine what treatment, if any, is required. The
product warranty specifically excludes liability for corrosion, erosion
or deterioration of equipment.
Field supplied strainers with 20-40 mesh (530-1060 microns) are
recommended, with 30 mesh (800 microns) being the optimum
choice. The strainers selected should have a mesh open area of at
least 6 square inches (39 square centimeters) for each unit being
serviced by the strainer. Using strainers with a smaller amount of
open area will result in the need for more frequent cleaning.
The heat exchangers in the units are 316 stainless steel plates with
copper brazing. The water piping in the heat exchanger is steel.
There may be other materials in the building’s piping system that
the designer may need to take into consideration when deciding the
parameters of the water quality.
Strainers should be selected on the basis of acceptable pressure
drop, and not on pipe diameter. The strainers selected should have a
pressure drop at the nominal flow rate of the units low enough to be
within the pumping capacity of the pump being used.
If an antifreeze or water treatment solution is to be used, the designer
should confirm it does not have a detrimental effect on the materials in
the system.
WARNING: Must have intermediate heat exchanger
when used in pool applications.
Contaminated Water
In applications where the water quality cannot be held to prescribed
limits, the use of a secondary or intermediate heat exchanger is
recommended to separate the unit from the contaminated water.
The following table outlines the water quality guidelines for unit heat
exchangers. If these conditions are exceeded, a secondary heat

Premium H Application Notes
The Closed Loop Heat Pump Concept
on individual units without system shut-down. Conditions remain
comfortable since each unit operates separately, allowing cooling
in one area and heating in another. Tenant spaces can be
finished and added as needed. Power billing to tenants is also
convenient since each unit can be individually metered: each pays
for what each uses. Nighttime and/or weekend uses of certain
areas are possible without heating or cooling the entire facility.
A decentralized system also means if one unit should fault, the
rest of the system will continue to operate normally, as well as
eliminating air cross-contamination problems and expensive high
pressure duct systems requiring an inefficient electric resistance
reheat mode.
The basic principle of a water source heat pump is the transfer
of heat into water from the space during cooling, or the transfer
of heat from water into the space during heating. Extremely high
levels of energy efficiency are achieved as electricity is used only
to move heat, not to produce it. Using a typical Premium H, one
unit of electricity will move four to five units of heat.
When multiple water source heat pumps are combined on a
common circulating loop, the ultimate in energy efficiency is
created: Our geothermal units on cooling mode are adding heat
to the loop which the units in heating mode can absorb, thus
removing heat from the area where cooling is needed, recovering
and redistributing that heat for possible utilization elsewhere in
the system. In modern commercial structures, this characteristic
of heat recovery from core area heat generated by lighting, office
equipment, computers, solar radiation, people or other sources, is
an important factor in the high efficiency and low operating costs of
our closed source heat pump systems.
Premium H Approach
There are a number of proven choices in the type of Premium H
system which would be best for any given application. Most often
considered are:

In the event that a building's net heating and cooling requirements
create loop temperature extremes, Premium H units have the
extended range capacity and versatility to maintain a comfortable
environment for all building areas. Excess heat can be stored
for later utilization or be added or removed in one of three ways;
by ground-source heat exchanger loops: plate heat exchangers
connected to other water sources, or conventional cooler/boiler
configurations. Your representative has the expertise and computer
software to assist in determining optimum system type for specific
applications.
• Closed Loop/Ground-Source Systems utilize the stable
temperatures of the earth to maintain proper water source
temperatures (via vertical or horizontal closed loop heat
exchangers) for Premium H extended range heat pump system.
Sizes range from a single unit through many hundreds of
units. When net cooling requirements cause closed loop water
temperatures to rise, heat is dissipated into the cooler earth
through buried high strength plastic pipe "heat exchangers."
Conversely if net space heating demands cause loop heat
absorption beyond that heat recovered from building core areas,
the loop temperature will fall causing heat to be extracted from the
earth. Due to the extended loop temperatures, AHRI/ISO 13256-1
Ground Loop Heat Pumps are required for this application.
The Closed Loop Advantage
A properly applied water source heat pump system offers many
advantages over other systems. First costs are low because
units can be added to the loop on an "as needed basis"- perfect
for speculative buildings. Installed costs are low since units are
self-contained and can be located adjacent to the occupied
space, requiring minimal ductwork. Maintenance can be done
10
HT SPECIFICATION CATALOG
Premium H Application Notes
In cooling dominated structures, the ground-source surface water
systems can be very cost effective especially where local building
codes require water retention ponds for short term storage of
surface run-off. Sizing requirements for the surface water is a
minimum of 500 sq. ft./ton of surface area at a minimum depth of
8 feet. The supplier should be contacted when designs for heating
dominated structures are required.
Because auxiliary equipment such as a fossil fuel boiler and
cooling tower are not required to maintain the loop temperature,
operating and maintenance costs are very low. Ground-source
systems are most applicable in residential and light commercial
buildings where both heating and cooling are desired, and on
larger envelope dominated structures where core heat recovery
will not meet overall heating loads. Both vertical and horizontally
installed closed-loops can be used. The land space required for
the "heat exchangers" is 100-250 sq. ft./ton on vertical (drilled)
installations and 750-1500 sq. ft./ton for horizontal (trenched)
installations. Closed loop heat exchangers can be located under
parking areas or even under the building itself.
Closed Loop/Ground Water
Plate Heat Exchanger
On large multi-unit systems, sizing the closed loop heat exchanger
to meet only the net heating loads and assisting in the summer
with a closed circuit cooling tower may be the most cost effective
choice.
Closed Loop/Ground Source
Surface Water
• Closed Loop/Ground Water Plate Heat Exchanger
Systems utilize lake, ocean, well water or other water sources to
maintain closed loop water temperatures in multi-unit Premium
H systems. A plate frame heal exchanger isolates the units from
any contaminating effects of the water source, and allows periodic
cleaning of the heat exchanger during off peak hours.
Operation and benefits are similar to those for ground-source
systems. Due to the extended loop temperatures, AHRI/
ISO 13256-1 Ground Loop Heat Pumps are required for this
application. Closed loop plate heat exchanger systems are
applicable in commercial, marine, or industrial structures where the
many benefits of a water source heat pump system are desired,
regardless of whether the load is heating or cooling dominated.
• Closed Loop/Ground-Source Surface Water Systems also
utilize the stable temperatures of Surface Water to maintain proper
water source temperatures for Premium H extended range heat
pump systems. These systems have all of the advantages of
horizontal and vertical closed loop systems. Due to the extended
loop temperatures, AHRI/ISO 13256-1 Ground Water or Ground
Loop Heat Pumps are required for this application.

closed loop temperatures above 60°F and a cooling tower to
maintain loop temperatures below 90°F. These systems are
applicable in medium to large buildings regardless of whether the
load is heating or cooling dominated. Due to the moderate loop
temperatures, AHRI/ISO 13256-1 Water Loop Heat Pumps are
required for this application.

HT SPECIFICATION CATALOG
Flow Rates
Load Flow Rate
Source Flow Rate
The load flow on all water to water products including the HT
Series should be 3 gpm per ton (typically the rated flow and the
highest flow shown in the capacity charts). Refer to the table
below. This flow rate is required especially when heating water to
limit the effects of the higher condensing temperatures of water
heating for radiant floor heating or domestic water use.
The source flow can range between 2.25 and 3 gpm per ton for
earth loops. For open loop well water systems the minimum flow
should be 1.5 gpm per ton. In earth loop systems where entering
water temperatures are expected to be above 95°F, 3 gpm per
ton should be used. In well systems where the water temperature
is below 50°F, 2 gpm per ton should be used to avoid nuisance
freeze detection trips.

HT SPECIFICATION CATALOG
Performance Standard (AHRI/ISO/ASHRAE 13256-2)
The performance standard AHRI/ASHRAE/ISO 13256-2 became effective January 1, 2000. This new standard has three major categories:
Water Loop, Ground Water, and Ground Loop.
Unit of Measure: The Cooling COP
The cooling efficiency is measured in EER (US version measured in Btuh per Watt. The Metric version is measured in a cooling COP
(Watt per Watt) similar to the traditional COP measurement.
Pump Power Correction Calculation
Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following
formula. This additional power is added onto the existing power consumption.
• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300
Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water flow in feet of
head.
ISO Capacity and Efficiency Calculations
The following equations illustrate cooling calculations:
• ISO Cooling Capacity = Cooling Capacity (Btuh) x 3.412
• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]
The following equations illustrate heating calculations:
• ISO Heating Capacity = Heating Capacity (Btuh) x 3.412
• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]

WARNING: Gray area represents antifreeze concentrations greater than 35% by weight and should be
avoided due to the extreme performance penalty they represent.
Antifreeze Correction Example
Antifreeze solution is propylene glycol 20% by weight for the source and methanol 10% for the load. Determine the corrected heating
at 30°F source and 80°F load as well as pressure drop at 30°F for an Premium H HT120. Also, determine the corrected cooling at 90°F
source and 50°F load.
The corrected heating capacity at 30°F/80°F would be:
98,500 MBTUH x 0.913 x 0.985 = 88,582 MBTUH
The corrected cooling capacity at 90°F/50°F would be:
113,200 x 0.969 x 0.962 = 105,523 MBTUH
The corrected pressure drop at 30°F and 36 GPM would be:
4.9 psi x 1.270 = 6.22 psi

General
Piping and Connections
Supply and return water connections shall be 2 in. [50.8 mm] FPT
copper fittings fixed to the cabinet by use of a captive fitting, which
eliminates the need for backup pipe wrenches.
The liquid source water-to-water heat pump shall be a single
packaged reverse-cycle heating/cooling unit. The unit shall be
listed by a nationally recognized safety-testing laboratory or
agency, such as ETL Testing Laboratory, Underwriters Laboratory
(UL), or Canadian Standards Association (CSA). The unit shall
be rated in accordance with Air Conditioning, Heating, and
Refrigeration Institute/International Standards Organization (AHRI/
ISO) and Canadian Standards Association (CSA-US). The liquid
source water-to-water heat pump unit shall be designed to operate
with source liquid temperatures between 30°F [1.1°C] and 110°F
[43.3°C] in cooling, and between 20°F [-6.7°C] and 90°F [32.2°C]
in heating.
Optional Back/Top Mount Water Connections - shall be
factory installed to the back corner post or top panel by use
of a captive fitting, which eliminates the need for backup pipe
wrenches.
WARNING: Warranty is void if strainers are not used
on the entering side of the load and source.
Electrical
Casing and Cabinet
Controls and safety devices will be factory wired and mounted
within the unit. Controls shall include 24 Volt activated compressor
contactors, 24VAC-75VA transformer with built in circuit breaker,
reversing valve coils, and anti short-cycle protection. A terminal
block with screw in terminals will be provided for field control
wiring. To prevent short cycling when the safety controls are
activated, the reset relay shall provide a lockout circuit that
requires resetting of low voltage supply or main circuit breaker. A
lockout signal shall be provided to the display to indicate a lockout
situation. Units shall be name-plated for use with time delay
fuses or HACR circuit breakers. Unit controls shall be 24 Volt and
provide heating or cooling as required by the remote thermostat/
sensor.
The cabinet shall be fabricated from heavy-gauge galvanized
steel and finished with corrosion-resistant powder coating. This
corrosion protection system shall meet the stringent 1,000 hour
salt spray test per ASTM B117. The interior shall be insulated with
1/2˝ thick, multi-density, coated glass fiber for noise suppression.
The control box shall have separate holes and knockouts for
entrance of line voltage and low voltage control wiring. All factoryinstalled wiring passing through factory knockouts and openings
shall be protected from sheet metal edges at openings by plastic
ferrules. The control box shall be field switchable from front to back
for improved application flexibility with quick attach low voltage
harnesses. The control box is shipped standard on the opposite
end of the water connections.
Optional GeoStartTM (Compressor Soft Starter) - shall
be factory installed for use in applications that require low
starting amps, reduced compressor start-up noise, off-grid,
and improved start-up behavior. GeoStart shall reduce normal
starting current by 60% on 208/60/1 units.
Refrigerant Circuit
All units shall contain two (2) sealed refrigerant circuits, each
containing a hermetic motor scroll compressor, bidirectional
thermal expansion valve assemblies, reversing valve, braze
plate heat exchangers, factory installed high and low pressure
safety switches, freeze detection, service ports, and liquid line
filter dryers. Compressors shall be scroll types designed for
heat pump duty with internal isolation and mounted on rubber
vibration isolators. Compressor motors shall have internal overload
protection. A high density sound attenuating blanket shall be
factory installed around the compressor to reduce sound. The
water to refrigerant heat exchangers shall be interlaced copper
brazed, 316 stainless plate steel, capable of withstanding 650
psig [4489 kPa] working pressure on the refrigerant side and
450 psig [3108 kPa] on the water side. The thermal expansion
valve assembly shall provide proper superheat over the liquid
temperature range with minimal “hunting.” The assembly shall
operate bidirectionally without the use of check valves. Externally
mounted pressure controlled water regulating flow valves are not
acceptable.
Microprocessor Control
The unit shall be controlled using an FX10 microprocessor which
sequences all functions and modes of operations. The control
shall interface with a (Y,B) thermostat, mechanical or electronic.
The control shall have the ability to communicate with N2 Open,
BacNet, or LonWorks protocols with optional communication card.
The control system shall have the following features:
1. Anti-short cycle time delay on compressor operation, time delay
shall be a minimum of 3 minutes
2. Random start on power up mode
3. Low voltage protection
4. High voltage protection
5. Unit shutdown on high or low refrigerant pressures
6. Unit shutdown for low water temperature
7. Source and Load heat exchanger low water temperature cutout
selectable for water or anti-freeze
8. Automatic intelligent reset (Unit will automatically reset 5
minutes after trip if the fault has cleared. Should a fault reoccur
3 times sequentially then permanent lockout will occur.)

9. A 4 x 20 digit backlit LCD to display the following:
a. Entering and leaving water temperatures
b. High pressure, low pressure, low voltage, high voltage, low water temperature cutout, and control status
10.The low pressure shall not be monitored for the first 120
seconds after a compressor start command to prevent
nuisance safety trips.
11.Remote fault indication on the thermostat
12.An accessory relay output tied to each compressor selectable
for normally open or normally closed
