Indoor Condensing Unit; Leveling Legs; Paperwork; Storage - DA Data Cool Series Installation, Operation And Maintanance Manual

Note to Installing Contractor: Condensation formation and frequent humidifier flushing (when
humidifier is installed) are normal functions of this equipment. Drain connections must be
made to ensure proper water removal. Unit will require drain connections for condensate
removal and water connections possibly for humidifier (when installed) makeup water, chilled
water and/or hot water. Installation of units above equipment that could sustain water dam-
age should be avoided.
1.3.1 Indoor Condensing Units
These 24" tall section is to be mounted using four threaded rods. Air cooled condensing units have
factory provided duct collars on the supply and intake air openings as appropriate. Split water cooled
condensing sections do not require airflow connections.
Typical installations have the condensing section physically near the evaporator, especially since
most have shared electrical line power.

1.4 Leveling Legs

Each Data Cool comes equipped with four leveling legs. When mounting the unit on the floor, to
ensure the best possible operation the leveling legs should be adjusted so that the unit is level.

1.5 Paperwork

Each Data Aire unit ships with a start-up sheet that must be completed during installation, and start up of
the unit(s). Also included in the paperwork is a warranty/information packet that provides important
wiring diagrams, specific component literature, warranty registration card and other valuable paperwork,
including a copy of this Installation/Operation and Maintenance manual.
A manila tag is attached to the outside panel to indicate articles that may have been packaged and
shipped loose within the unit cabinet. This could be the thermostat or other optional control devices that
are not factory mounted.
It is the responsibility of the installing contractor to return the start-up sheet and warranty registration
card to Data Aire for proper activation of the unit warranty. Failure to do so may cause delays in
warranty related services and in some cases void the warranty.

Storage

Your Data Aire equipment comes ready for immediate installation. In some instances it may be necessary
to store the equipment for a period of time. If you must store the equipment it should be done in a dry
area, out of the weather, protected from freezing temperatures, protected from damage by other equipment
in storage or transportation equipment, never stacked, and avoid frequent relocation.
If equipment is stored for longer than 30 days special precautions must be taken to avoid coil damage.
All coils should be charged and sealed with a low pressure (less than 25 psig) inert gas, such as nitrogen.
This prevents contaminates from entering the coils; then when the seal is broken at installation, the rush
of escaping gas verifies the coil is still leak free. If coils are not charged and sealed condensation mixes
with air pollutants forming a weak acid and can cause pin hole leaks to develop in the coil tubes.
When equipment is installed after storage caution should be taken to inspect and replace, if required,
rubber hoses. All moving parts, such as blowers and motors, should be hand tested to ensure that they
are free and clear prior to start-up. Finally, verify that all lubrication is fresh and full.
It is the responsibility of the installing contractor to return the start-up sheet and warranty registration
card to Data Aire for proper activation of the unit warranty. Failure to do so may cause delays and in
some cases void the warranty.
