ENVISION SERIES INSTALLATION MANUAL

Connection to Air Coil

Figures 1 and 2 illustrate typical Envision Split installations. The table on page 9 shows typical lineset diameters and maximum length. Linesets over 60 feet are not recommended. If the lineset is kinked or deformed and cannot be reformed, the bad section of pipe should be replaced. A restricted lineset will affect unit performance. As in all R-410A equipment, a reversible liquid line filter drier is required to insure all moisture is removed from the system. This drier should be replaced whenever “breaking into” the system for service. All linesets should be insulated with a minimum of 1/2” closed cell insula- tion. All exterior insulation should be painted with UV resistant paint or covering to insure long insulation life.

Air Handler Installation

Air handlers used with dual capacity units must be capable of operating with a minimum of 2 blower speeds. Refer to the manufacturer’s instructions for the blower coil unit for details on installing the air handling portion of the system. All blower coil units/air coils must be installed as specified by the manufacturer’s installations instructions. However, the following rec- ommendations should be considered to minimize noise and service problems.

An air filter must always be installed upstream of the air coil on the return air side of the air handler of furnace. If there is limited access to the filter rack for normal maintenance, it is suggested that a return air filter grille be installed. Be sure that the return duct is properly installed and free of leaks to prevent dirt and debris from bypassing the filter and plugging the air coil.

Ensure that the line set size is appropriate to the capacity of the unit (refer to page 9). Line sets should be routed as di- rectly as possible, avoiding unnecessary bends or turns. All wall penetrations should be sealed properly. Line set should not come into direct contact with water pipes, floor joists, wall studs, duct work, floors, walls and brick. Line set should not be suspended from joists or studs with a rigid wire or strap which comes into direct contact with the tubing. Wide hanger strips which conform to the shape of the tubing are recommended. Isolate hanger straps from line set insulation by using metal sleeves bent to conform to the shape of insulation. Line set insulation should be pliable, and should completely surround the refrigerant line.

Notes: Improper installation of equipment may result in undesirable noise levels in the living areas.
