Inspection

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.

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 nal location.

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. Inert gas must be charged into piping during welding.

3. System must be thoroughly leak checked and

evacuated before initial charging. High vacuum

gauge capable of reading microns is mandatory.

Dial indicating pressure gauges are not acceptable.

4. Power supply to system must meet the

following conditions:

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%.

5. All controls and safety switch circuits properly

connected per wiring diagram.

6. Factory installed wiring must not be changed without

written factory approval.

Installation

Note: Installation and maintenance to be performed

only by qualied personnel who are familiar with

local codes and regulations, and experienced

with this type of equipment.

Caution: Sharp edges and coil surfaces are a potential injury

hazard. Avoid contact with them.

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

I-beam frame to support the unit above the roof. Use of vibration

pads or isolators is recommended. The roof must be strong

enough to support the weight of the unit. Concrete slabs used

for unit mounting should be installed level and be properly

supported to prevent settling. A one-piece concrete slab with

footings extending below the frost line is recommended.

The condenser should be located far enough away from any

wall or other obstruction to provide sucient 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 4 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 exible 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 berglass and sealing

compound around the lines to minimize vibration and retain

exibility in the lines.

The unit needs to be secured in its nal location. Holes are

provided in the base runner for this purpose.

Warning: This equipment may contain a substance

which harms the public health and

environment by destroying ozone in the

upper atmosphere. Venting of certain

refrigerants to the atmosphere is illegal.

Refrigerant recovery devices must be used

when installing or servicing this product.

Consult your local codes for requirements

in your location.

Warning: There may be more than one source of

electrical current in this unit. Do not

service before disconnecting all power

supplies.
