- 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.
