Responsibility should be assigned to a dependable individual at the job site to receive material. Each shipment should be carefully checked against the bill of lading. The shipping receipt should not be signed until all items listed on the bill of lading have been accounted for.
Check carefully for concealed damage. Any shortage or damages should be reported to the delivering carrier.
System Warranty
This equipment is designed to operate properly and produce rated capacity when installed in accordance with accepted industry standards. Failure to meet the following conditions may result in voiding of the system warranty:
1.System piping must be installed following industry standards for good piping practices.
2.System must be thoroughly leak checked before initial charging.
3.Power supply to system must meet the following conditions:
Damaged material becomes the delivering carrier's responsibility, and should not be returned to the manufacturer unless prior approval is given to do so. When uncrating, care should be taken to prevent damage. Heavy equipment should be left on units shipping base until it has been moved to the final location.
a.Voltage for 208/230 motors not less than 195 volts or more than 253 volts.
b.All other voltages must not exceed +/- 10% of nameplate ratings.
c.Phase imbalance not to exceed 2%.
4.All controls and safety switch circuits properly connected per wiring diagram.
5.Factory installed wiring must not be changed without written factory approval.
Installation
NOTE: Installation and maintenance to be performed only by qualified personnel who are familiar with local codes and regulations, and experienced with this type of equipment.
Unit Location
Units are designed for outdoor application and may be mounted on a roof or concrete slab (ground level installation). Roof mounted units should be installed level on steel channels or an
CAUTION: Sharp edges and coil surfaces are a potential injury hazard. Avoid contact with them.
The dry cooler should be located far enough away from any wall or other obstruction to provide sufficient clearance for air entrance. Do not attach ductwork to the coil inlet or fan outlet. Care should be taken to avoid air recirculation conditions that can be caused by sight screening, walls, etc. Also keep unit fan discharge away from any building air intakes. See page 10 for space and location requirements.
Sound Vibration
Units should be installed away from occupied spaces and above or outside of utility areas, corridors and auxiliary spaces to reduce the transmission of sound and vibration to occupied spaces. The refrigerant piping should be flexible enough to prevent the transmission of noise and vibration from the unit into the building. If the refrigerant lines are to be suspended from the structure of the building, isolation hangers should be used to prevent the transmission of vibration. Where piping passes through a wall, it is advisable to pack fiberglass and sealing compound around the lines to minimize vibration and retain flexibility in the lines.
The unit needs to be secured in its final location. Holes are provided in the base runner for this purpose.
WARNING: There may be more than one source of electrical current in this unit. Do not service before disconnecting all power supplies.
