A Step By Step Guide to Heating Systems Installation

HVAC stands for Heating, Ventilation and Air conditioning. Unlike any other electronic appliance, you just cannot survive without an HVAC system as it is responsible to maintain the indoor air quality of your home or commercial space. They serve an intelligent way of cooling your entire home quietly and conveniently.

Follow this step by step guide to install the HVAC system successfully:

1.    Locate an unconditioned space

Areas such as garage, attic, basement, closet, utility room or crawl space are perfect as they can protect the fan coil unit from weather. However, check if you are violating the local codes. Don’t forget to check the location of return air filter box and duct. You need to install a secondary drain pan and/or a drain switch too.

The unit may be installed on a platform or suspended from a pre-assembled suspended platform and must be close enough to the selected return air box opening.

 2.    Cut open the return box opening

Select where to cut the return air duct. Preferably avoid installing it in the kitchen, dining room or living room, unless the duct can be installed with a 180 degree bend. Now, the fan coil is ready to pass through the opening. But you can wait until complete installation as you may want to pass materials through this opening.

 3.    Build a platform

Note the size of the fan coil unit and construct a simple platform. Detailed instruction in the instruction manual will help you. Recommendations suggest use of 2- by 8-inch stud lumber and a minimum of 1/2-inch plywood for platform construction.

Use the provided isolation strips under the unit for better performance. For a suspended platform, hold it by ¼ inch threaded rods. Also, leave some room for servicing.

 4.    Attach supply plenum ring

The supply plenum ring must be attached several inches lower than the fan coil unit to help the fan move past the platform edge to accommodate the plenum ring. Before mounting the ring, ensure that the plenum ring gasket attaches to the fan coil cabinet.

 5.    Get the condensate drain connected

Connect the condensate drain to the unit by referring to the instructions. Remember to run the drain line (pitched ¼ inch per foot) from the trap to a suitable drain and be sure to check with the local codes. Take care not to connect to a closed drain system.

 6.    Attach the refrigerant lines

You are ready to connect the refrigerant lines from the outdoor condensing unit to the indoor fan coil unit. It is really important to follow the instructions in the outdoor unit manual for proper installation

 7.    Connect plenum duct and supply tubing

Considering you have already done the sizing calculations, the plenum duct can now be run in any location that is accessible for the supply tubing attachment. We suggest keeping a distance of 18 inches between the plenum duct components and the fan coil unit. Also, it is better to keep the use of the elbows and tees to a minimum to maintain the heating systems’ pressure.

Some other important instructions:

  • Cut off the male end of the first section and then proceed to inserting plenum duct section (pushed tightly) into receiving collar on the fan coil unit. Now, it is time to flatten the sheet metal tabs against the plenum duct and insert the flat head pins.
  • The piece of foil face insulation must be wrapped and taped over the taped joint & against the fan coil unit.

Continue to assemble plenum duct ensuring that the shiplap joints are snug & securely taped.

 8.    Connect Terminator Outlets And Sound Attenuation Tubing

Mark the locations for the room terminators to be installed & ensure that its center is 5 inches from the wall edge. Drill a 1/8 inch hole and allow 2 inches of clearance around. Assemble the room terminator to the sound attenuation tubing by fitting the connectors tight.

 9.    Install the supply tubing

It’s time to complete the installation process by installing supply tubing. Cut the supply tubing & install the connector by threading it to the cut end. Avoid sharp bends to invite less repair and maintenance. Place the plenum gasket & takeoff connector into the plenum hole. Then insert the plenum fasteners and snap those using pliers. Install a connector into the remaining open supply tubing end and connect the connector from tubing to the plenum takeoff. Complete the installation process by installing your return air duct and return air box.
