First Company 3.5 Ton 14.6 EER Hydro-Tech Cupronickel Water Source Heat Pump is available to buy in increments of 1


The HydroTech WSVX Series Water Source Heat Pump by First Co. was designed by contractors, for contractors. The Hydro Tech is the most feature-packed product available today. It includes many standard features found only in higher priced products.

Standard Features:

  • 2-speed blower operation in the summer: The Hydro-Tech removes more moisture from the air by operating on a lower speed for up to 10 minutes before quietly switching to a higher speed. An even higher speed is also available for high static applications.
  • Having the smallest footprint of any product in its class ensures a perfect fit when replacing older models in tight closets (even the 036 model is only 21.5 wide by 21.5 deep!).
  • Blower assemblies are field-reversible 180 degrees (except model 040). This option can improve airflow when the units are installed in closets with very little room for supply plenums.
  • Optional Vacated Premises Control (VPC) kit with reset feature: Ensures that the unit will operate a minimum of one or two hours per day during extended periods of unoccupancy. This option also includes an automatic reset feature. If a fault occurs, the system will shut down, but then automatically reset every 24 hours. If the same fault exists each day, the unit will lock out on the fourth day and have to be manually reset.
  • Superior insulation: Fully insulated with"Tuf-Skin",which offers greater sound absorption and better thermal efficiency. The insulation has a special acrylic coating that's formulated with an EPA registered anti-microbial agent.
  • Removable discharge flange: Provides additional installation clearance.
  • Tool-less filter rack installation: Can be installed after the unit is in the closet, providing additional installation clearance.
  • State-of-the-art Digital Control Module

Additional Standard Features:

  • 100 Factory Tested
  • R-410A Refrigerant - All units operate with environmentally friendly R-410A refrigerant.
  • Painted Cabinet - Durable baked-on powder coat finish
  • Non-corrosive Thermoplastic Condensate Pan- Sloped for positive drainage
  • High and Low pressure Service Ports
  • Refrigerant Filter-drier and Discharge Muffler
  • Panel-mounted FPT Water Connections - No back-up wrench needed.
  • Removable Panels for Service
  • 50 VA Transformer
  • 1Throwaway Filter

Optional Features:

  • Cupronickel Coaxial Heat Exchanger
  • Vacated Premises Control
  • E-Coated Air Coil Corrosion Protection
  • Compressor Cover: A heavy duty, insulated compressor cover that reduces unwanted compressor noise (must be field installed on the WSVC unit before the unit is installed in the closet).
  • Part No. K3821332 (fits WSVC18-42)
  • Part No. K4251 (fits WSVC48/60)
  • Evaporator Temperature Sensor
