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.

Typical closet installation with louver door return & with ducted return Duct and attenuation Discharge ductwork is normally used with these conditioners. Return air ductwork may also be required, but will require field installation of a 1" or 2" (21 or 51mm) return air duct collar/ filter rack kit.
PAGE 20
Ventilation Air Outside air may be required for ventilation. The temperature of the ventilation air must be controlled so that mixture of outside air and return air entering the conditioner does not exceed application limits. It is also general practice to close off the ventilation air system during unoccupied periods (night setback). The ventilation air system is generally a separate building subsystem with distribution ductwork.
PAGE 21
Piping 1. All units are recommended to be connected to supply and return piping in a two-pipe reverse return configuration. A reverse return system is inherently self-balancing and requires only trim balancing where multiple quantities of units with different flow and pressure drop characteristics are connected to the same loop. A simple way to check for proper water balance is to take a differential temperature reading across the water connections.

Automatic flow controlled devices must not be installed prior to system cleaning and flushing. 10. A high point of the piping system must be vented. 11.

3. 4. 5. 6. Supplemental heater and circulator pump should be shut off. All drains and vents should be opened to completely drain down the system. Short circuited supply and return runouts should now be connected to the conditioner supply and return connections. Teflon tape is recommended over pipe dope for pipe dope for pipe thread connections. Do not use sealers at the swivel flare connections of hoses. Trisodium phosphate was formerly recommended as a cleaning agent during flushing.

Start-Up 1. 2. Open all valves to full open position and turn on power to the conditioners. Set thermostat for "Fan Only" operation by selecting "Off " at the system switch and "On" at the fan switch. If "Auto" fan operation were selected, the fan would cycle with the compressor. Check for proper air delivery. 3. All units have three-speed motors. 4. Set thermostat to "Cool". Many conditioners have time delays which protect the compressor against short cycling.
PAGE 25
Maintenance 1. 2. 3. 4. 5. Normal maintenance on all conditioners is generally limited to filter changes. Lubrication of the fan motor is not required. Filter changes are required at regular intervals. The time period between changes will depend upon the project requirements. Some applications such as motels produce a lot of lint from carpeting and linen changes. It is suggested that the filter be checked at 60-day intervals for the first year until experience is acquired.
