Installation

2.0INSTALLATION

Read this entire installation section before starting installation. This section details dimensional, electrical and piping information and specifications that affect the placement of the PFH unit in rela- tion the connected evaporator unit, other outside units, barriers and walls.

Be particularly mindful of service and airflow clearances and maximum equirvalent piping distances and in elevation differences between PFH and connected evaporator unit. Consult and confirm appli- cations with your Emerson Network Power representative when applications exceed any of these specifications.

2.1Equipment Inspection

When the unit arrives, inspect all items for any visible or concealed damage. Report any damage to the carrier immediately and file a damage claim; send a copy of the claim to Emerson Network Power or your local Emerson sales representative.

If possible, maintain equipment and packaging until it is at the installation location.

2.2Location Considerations

To ensure an adequate air supply, locate all condensing units in a clean-air area, away from loose dirt and debris that can clog the coil. Avoid ground-level sites with public access or areas that are exposed to heavy snow accumulation. Locate unit to allow maximum security and maintenance accessibility.

Do not locate condensing units near steam, hot air or fume exhausts. Do locate units at least 18 in. (457mm) from walls, obstructions or adjacent units. For multiple unit installations, space unit so that the hot condenser exhaust air is not directed toward the condenser air inlet of an adjacent unit.

Install a solid base at least 2 in. (51mm) higher than the surrounding grade and 2 in. (51mm) larger than condensing unit base dimensions and capable of supporting the condenser’s weight.
