Specifications

Transportation and Storage
Upon receipt of the equipment, check the carton for visible damage. Make a notation on the shipper's
delivery ticket before signing. If there is any evidence of rough handing, the cartons should be opened at
once to check for concealed damage, If any damage is found, notify the carrier within 48 hours to establish
your claim and request their inspection and a report. The Warranty Claims Department should then be
contacted.
Don't stand or transport the machine on their sides, For storing, each carton is marked with "up-arrows.
In the event that elevator transfer makes horizontal positioning unavoidable, absolutely insure that the
machine is in the normal upright position for at least 24 hours before operating.
Temporary storage at the joist must be indoors, completely shields from rain, snow, etc. High or Low
temperature naturally associated with weather pattern will not harm the conditioners. Excessively high
temperature of 160°F (60ºC) may deteriorate certain plastic materials and cause permanent damage. In
addition, the solid-state circuit boards may experience operating problems.
Installation
General
1. To prevent damage, this equipment should not be operated for supplementary heating and cooling
during the construction period.
2. Inspect the carton for any specific tagging numbers as requested by the installing contactor. At this time
the voltage, phase and capacity should be checked against the plans.
3. Check the unit sizes against the plans to be sure that the unit will be installed in the correct location.
4. Before installation, check the available closet dimension versus the dimensions of the unit.
5. Pay attention to the location and routing of water piping, and electrical wiring. The locations of these
items are clearly marked on submittal drawings.
6. The installing contractor will find it beneficial to confer with piping, sheet metal, ceiling and electrical
foreman together before installing any conditioners.
Unit location
1. Locate the unit in an area that allows for easy removal of the filter and access panels, and has enough
space for service personnel to perform maintenance of repair. Provide sufficient room to make water,
electrical and duct connections.
2. The contractor should make sure that access has provided including clearance for duct collars and
fittings at water and electrical connections.
3. Allow adequate room around the unit for a condensate trap.
4. The unit can be installed in an equipment room. However, closet installations are more common for
small vertical type units. Generally, the unit is located in the corner of a closet with the non-ducted,
return air facing 90° to the door and the major access panels facing the door (Figure A). Alternatively,
the unit can have a ducted return air with the opening facing the door and the major access panels
facing 90° to the door (Figure B).
5. It is recommended that the unit be located on top of a vibration absorbing material such as
rubber or carpet to reduce any vibration.
6. If optional field installed controls are required (boilerless systems), space must be provided for the
enclosure to mount around the corner from the electrical entrances. Do not locate the side of the unit
too close to a wall.
