The document ensures the installer is conversant with safety considerations and best installation practices for the unit.
SAFETY CONSIDERATIONS
Key safety measures are highlighted to prevent explosion, fire, electrical shock, or other hazardous conditions that may lead to death, personal injury or property damage. The emphasis is on adherence to safety codes, use of protective clothing, and the need for a fire extinguisher during the installation process. It is also noted that all installation, adjustments, or modifications should be carried out by a qualified installer using factory-authorized kits.
INSTALLATION RECOMMENDATIONS
Installation recommendations include techniques designed to minimize noise and vibration. These include locating the unit away from areas where operating sounds could be disruptive, using appropriate tube diameters, and minimizing tubing bends. Key advice includes sealing refrigerant tube penetrations with silicon-based caulk, avoiding direct tubing contact with other structural elements, and properly insulating vapor tubes.
Tools For Installation
Installers are instructed to use certain tools and practices including using hanger straps that conform to the tubing insulation and isolating them with metal sleeves to prevent direct contact. Safety glasses, protective clothing, and gloves are outlined as essential gear.
Handling Refrigerants
There’s a warning about R-410A refrigerant systems which operate under higher pressures than standard R-22 systems and it’s strictly advised not to use R-22 service equipment on R-410A equipment to prevent any operation or safety hazards.
Initial Unit Inspection
Before installation, the manual advises inspecting the new unit and filing any claims with the shipping company if there are damages or incomplete shipments. It’s important to locate the unit’s rating plate and wiring label, which contain necessary information for a proper installation.
