Design Highlights

The NRF 350073 incorporates a dual‑coil heat exchanger that maximizes surface area while maintaining a slim profile. The aluminum fins are engineered with a high thermal conductivity coefficient, ensuring rapid heat dissipation even under heavy load conditions. A built‑in desiccant system automatically removes moisture from the refrigerant line, extending component life and preventing corrosion.

Compatibility

This unit is fully compatible with Mitsubishi Smart series air‑conditioners, as well as a wide range of other HVAC brands that support R‑410A refrigerants. The Easy Fit mounting kit allows for quick installation on existing ductwork or new setups without the need for extensive modifications.

Installation Guide

1. Site Preparation: Ensure a stable, level surface with adequate clearance (minimum 30 cm) around the unit for airflow and maintenance access.
2. Mounting: Attach the mounting brackets to the wall or floor using corrosion‑resistant screws. Verify that the brackets are level before securing the condenser.
3. Electrical Connection: Connect the power supply following local electrical codes. The unit requires a 240 V, single‑phase input with a dedicated circuit breaker.
4. Refrigerant Line Installation: Route the suction and discharge lines to the indoor evaporator coil. Use insulated tubing to minimize heat gain/loss.
5. Desiccant Activation: Once connected, allow the desiccant system to circulate for at least 30 minutes before turning on the unit.
6. Commissioning: Perform a pressure test and verify that all gauges read within specified ranges. Adjust refrigerant charge if necessary.

Maintenance & Care

• Cleaning: Remove dust from fins with a soft brush or vacuum attachment every three months.
• Inspection: Check for leaks, corrosion, and mechanical wear biannually.
• Desiccant Replacement: Replace the desiccant cartridge after 12 months of operation or if moisture buildup is detected.
• Electrical Checks: Inspect wiring insulation and connections annually to prevent short circuits.
