Refrigerant Piping; Electrical And Wiring; Electrical Data - McQuay A08019026011 Manual De Instrucciones

• Do not use contaminated, dented or used copper tubing.
• Do not use copper tubes with less than 0.8 mm thickness.
• Use a flare tool specially for R410A.
• Do not use mineral oil on flare part.
• Use proper torque wrench to tight the flare nuts. If the torque strength is weak, gas leakage may occur. If it is too tight, the
flare nut may crack and it may be non-removable.
• Purge the fan coil unit first to remove any air trap in the unit.
• Use a vacuum pump with a back flow preventing adapter to prevent the vacuum pump oil mix with R410A which will
create sludge and damage the equipment.
• Vacuum unit thoroughly to -76cmHg.
• At all times when performing brazing work, ensure nitrogen gas is flow into finned coil and all related tubing to prevent
carbon formation inside the copper tubes.
• Insulate the piping with polyurethane foam with more than 15mm thickness to prevent capacity losses and water condensation.
NOTE
For piping length limitation and additional refrigerant charge guide above 2m pipe length, please refer to coupling water
source heat pump unit manual.
• Beware that R410A standard operating pressure is about 1.6 times higher than R22.
• Refer to the wiring diagram provided on the unit when making electrical wiring connection.
• Power supply is from fan coil unit connection.
• All field wiring must comply with your national or local wiring regulation.
• All terminal wiring must be firmly connected. Improper connection can cause electric shock, short circuit or fire breakout.
• A circuit breaker must be provided for over current protection.
• All safety precautions need to be strictly adhere.
• Do not ground any electrical equipment to the water piping.
• Do not operate unit with wet hand(s). It will result in electrical shock.
