Bosch CL060-1VTC-LLT-PUA Water Source Heat Pump 5 Ton

Product Description

The BOSCH CL060-1VTC-LLT-PUA is a 5-ton vertical water source heat pump (WSHP) built for commercial and residential hydronic HVAC systems. It runs on R-454B low-GWP refrigerant and operates on 208/230 volts single-phase power. The unit delivers both heating and cooling performance in water-loop or geothermal applications while meeting ASHRAE 90.1 efficiency standards. A slide-out blower assembly and swing-out electrical box reduce service time significantly. The left-return airflow configuration suits vertical installation layouts common in commercial multi-zone and residential geothermal builds. Licensed HVAC technicians handle installation and commissioning.

This unit is designed for vertical installation in commercial and residential water-loop or geothermal HVAC systems. The left-return airflow orientation fits equipment closets, mechanical rooms, and vertical shaft installations. At 5 tons of nominal capacity, it handles mid-to-large zone loads in both new construction and replacement projects. The CL Series design includes enhanced air coil access panels and reduced-vibration components for quieter operation in occupied spaces. Water coil freeze protection is included as standard, making the unit suitable for geothermal ground-loop and building water-loop configurations.

Key Features

• 5-ton nominal capacity rated for commercial and residential water-loop or geothermal systems
• R-454B low-GWP refrigerant reduces environmental impact versus legacy refrigerants
• Slide-out blower assembly simplifies routine maintenance and blower replacement
• Swing-out electrical box provides fast access to controls and wiring terminations
• Meets ASHRAE 90.1 efficiency requirements for commercial HVAC applications
• Standard water coil freeze protection included for geothermal and water-loop installs

Compatibility

Designed for use in geothermal ground-loop and building water-loop heating and cooling systems in commercial and residential applications. Suitable for vertical left-return installation configurations in new construction and replacement WSHP projects.

Installation Notes

Installation must be performed by a licensed HVAC technician familiar with water source heat pump systems. Shut off water loop flow and disconnect electrical power before servicing or connecting the unit. Refrigerant handling requires EPA Section 608 certification. Follow local mechanical codes and ASHRAE guidelines for water loop design, flow rates, and entering water temperature ranges.
