Carrier Indoor & Outdoor Split Geothermal Heat Pumps - Rev.: 08/10/05

•  Eight Capacities 018, 024, 030, 036, 042, 048, 

and 060.

•  Voltage availability in 208-230/60/1. 
•  Stackable cabinets.
•  Extended range operation (20-120°F EWT) 

and fl ow rates as low as 2.25 gpm per ton 
(geothermal closed loop operation).

•  Circuit breaker protected loop and hot water 

gen er a tor pumps.

•  Field selectable low temperature cut-out selection 

setting for geothermal closed loop operation.

•  Easily accessible electrical box for wiring.
•  Weather-resistent cabinet.
•  Internally-mounted (fi eld installed) Flow Controller
•  Precharged refrigerant circuit with backseating 

service valves for quick installation.

•  ARI/ASHRAE/ISO 13256-1 ratings for heating 

COP’s, cooling EER’s and low water fl ow rates.

•  Operating and temperature range allow 

shorter loops.

•  Optional remoted-mounted hot water generator 

with internal pump generates hot water at 
considerable savings.

•  Rugged, super quiet, and highly effi cient scroll 

compressors (rotary for size 018).

•  Oversized coaxial tube water to refrigerant heat 

exchangers operate at low liquid pressure drop.

•  Convoluted copper (and optional cupronickel) 

water tube functions effi ciently at low-fl ow rates 
and provides freeze-damage resistance.

•  Removable side and top panels for easy access to 

water/refrigerant circuits.

•  Low ambient temperature switch activates loop 

pump in extreme temperatures.

•  Solid state digital compressor module provides 

reliable lockout, diagnostic, and time delay functions.

•  High side loss-of-charge sensing reduces nuisance 

low pressure faults.

•  LED Fault and status indication with memory for 

easy diagnostics.

•  High and low pressure service ports in the 

refrigerant circuit.

•  Refrigerant sensing freeze protection for more 

accurate low temperature cut-out.

•  All units are built on our Integrated Process 

Control Assembly System (IPCS). The IPCS is 
a unique state of the art manufacturing system 
that is designed to assure quality of the highest 
standards of any manufacturer in the water-source 
industry. Our IPCS system:

 - 

Verifi es that the correct components are 

  being assembled.

  - Automatically performs special leak tests on 

  all joints.

  - Conducts pressure tests.
  - Performs highly detailed run test unparalleled in  

  the HVAC industry.

 - 

Automatically disables packaging for a “failed” unit.

  - Creates computer database for future service   

  analysis and diagnostics from run test results.

•  Heavy gauge galvanized steel cabinets are epoxy 

powder coated for durable and long-lasting fi nish.

•  All refrigerant brazing is done in a nitrogen 

atmosphere.

•  All units are deep evacuated to less than 100 

microns prior to refrigerant charging.

•  All joints are both helium and halogen leak tested 

to insure annual leak rate of less than 1/4 ounce.

•  Coaxial heat exchanger, refrigerant suction lines 

and all water lines are fully insulated to eliminate 
condensation problems in low temperature 
applications.

•  Noise Reduction features include: double isolation 

mounted compressors, compressor springs, 
insulated compressor compartment, and interior 
cabinet insulation using 1/2” coated glass fi ber.

•  Safety features include: high pressure and loss of 

charge to protect the compressor; condensate 
overfl ow protection; low water temperature 
limit sensors to safeguard the coaxial heat 
exchanger and air coil; hot water high limit and low 
compressor discharge temperature switch provided 
to shut down the hot water generator when 
conditions dictate. Fault lockout enables emergency 
heat and prevents compressor operation until 
thermostat or circuit breaker has been reset.
