2. Safety considerations: Before starting the installation, make sure to follow all safety codes and wear appropriate safety gear such as safety glasses, protective clothing, and work gloves. Have a fire extinguisher available and consult local building codes and electrical codes for compliance.
3. Mounting the unit: Choose a solid and level mounting pad for the impact driver. If required by local codes or conditions, attach the unit to the pad using tie-down bolts through the knockouts provided in the unit's base pan. Refer to the unit mounting pattern in the user manual for the appropriate base pan size and knockout hole location.
4. Clearance requirements: Ensure that there is sufficient space around the unit for airflow clearance, wiring, refrigerant piping, and service. Maintain a clearance of 30 inches to the service end of the unit and 48 inches above the unit. Allow a 6-inch clearance on one side of the unit and a 12-inch clearance on all remaining sides. Maintain a distance of 24 inches between units. Position the unit in a location where water, snow, or ice from the roof or eaves cannot fall directly on it.
5. Piping connections: Make sure to properly connect the refrigerant tubing to the unit. Use refrigerant-grade tubing of the correct size and condition. Follow the recommended liquid and vapor tube diameters as specified in the user manual. Install the factory-supplied liquid-line filter drier and ensure that all connections are brazed properly using industry-accepted methods and materials.
6. Electrical connections: Make sure to follow all electrical safety precautions. Route the ground and power wires through the power wiring hole provided in the unit's control box. Connect the ground wire to the ground connection in the control box for safety. Connect the power wiring to the contactor as shown in the user manual. Route the control wiring through the control wiring grommet and connect the leads to the control wiring terminals. Use the appropriate wire size and follow NEC or local codes for wiring requirements.
7. Start-up and testing: After completing the installation, turn on the power to the indoor and outdoor units. Set the room thermostat to the desired temperature and mode (cooling). Allow the unit to operate for at least 15 minutes and check the system refrigerant charge using the charging information provided in the user manual.
