DANGER
The heat pump in this ventilation unit is designed to use R-410A high pressure
refrigerant only. Hazards exist that could result in personal injury or death.
Installation, maintenance, and service should only be performed by an HVAC
technician qualified in R-410A refrigerant and using proper tools and equipment.
Due to much higher pressure of R-410A refrigerant, DO NOT USE service equipment
or tools designed for R22 refrigerant.
DANGER
Never use oxygen to pressurize a refrigeration system. Oxygen can explode on
contact with oil and result in personal injury or death. When using high pressure
gas such as nitrogen for pressurizing a refrigeration system, ALWAYS USE A
PRESSURE REGULATOR that can control the pressure down to 1 or 2 psig.
SAFETY WARNINGS
For your safety, wear eye protection, gloves, and protective clothing when handling
R-410A refrigerant or POE oil and when brazing. Have a fire extinguisher nearby
when brazing.
DANGER
Before installing or servicing, always turn off the main power to the system and
install a lock out on the disconnect switch.
