Daikin offers a simple system design, increases system redundancy by providing individual air conditioning systems per floor, lowers maintenance costs, eases operation and maintenance, and provides the lowest life cycle cost available.
2.0 INSTALLATION The unit is designed for indoor installation only. Installation of this unit must conform to local building codes and/or regulation. The unit shall be operated according the limit specified in Table 1. Table 1: Unit Operating Limit MAXIMUM WORKING SAFETY PRESSURE CONDENSER TEST PRESSURE (UNIT)
Units are shipped with a protective covering, which should remain in place while the unit is being moved to its final location. Unit weights are listed in Table These weights must be referred to when selecting a crane for rigging. Contact your Daikin Sales Office if you have any questions regarding unit weights.

5.2 DUCTING Supply Air For connection of supply ductwork directly to the unit, a duct collar must be mounted at the unit outlet. When connecting ductwork to the unit, a canvas type connecting collar is recommended. If a field fabricated plenum is used, canvas type connectors are recommended at the duct connection to the plenum. Units are also available with a factory provided discharge plenum.
Condenser Water Piping All internal condenser water piping is completed factory assembled. Field piping should be connected to the pipes that are stubbed out at the panels. Supply water must be connected to the factory piping as indicated by the markings on the unit. Condensate Drain Connections The condensate drain connection is located on the drain pan that forms the partition between the coil and condensing section.
5.5 SUPPLY AIR BLOWER ADJUSTMENT The RPM of the supply air blower will depend on the required CFM, the unit accessories and the static resistances of both the supply and the return air duct systems. With this information, the RPM for the supply air blower can be determined from fan performance curves.
6.0 ELECTRICAL CONNECTION Install electrical wiring in accordance with the National Electric Code and / or local regulations. A fused disconnect switch must be used in a separate circuit from the main power panel. The switch should be reasonably close to the unit for convenience in servicing.
