SHIPPING INSPECTION

Always keep the unit upright; laying the unit on its side

or top may cause equipment damage. Shipping damage,

and subsequent investigation is the responsibility of

the carrier. Verify the model number, specications,

electrical characteristics, and accessories are correct

prior to installation. The distributor or manufacturer will not

accept claims from dealers for transportation damage or

installation of incorrectly shipped units.

This product is designed and manufactured to comply

with national codes. Installation in accordance with such

codes and/or prevailing local codes/regulations is the

responsibility of the installer. The manufacturer assumes

no responsibility for equipment installed in violation of any

codes or regulations. Rated performance is achieved after

20 hours of operation.

Rated performance is delivered at the specied airow.

See outdoor unit specication sheet for split system models

or product specication sheet for packaged and light

commercial models. Specication sheets can be found at

Outdoor units are approved for operation above 55°F in cooling mode. Operation below 55°F requires the use of an approved low ambient kit. Note: LAKT01 Low ambient kit cannot be used with outdoor units containing ECM motors. should not be in contact with or be an integral part of the building foundation. Ensure the foundation is sufficient to support the unit. A concrete slab raised above ground level provides a suitable base.

RECOMMENDED INTERCONNECTING TUBING (Ft) WARNING Cond Unit Tons To avoid possible explosion, use only returnable (not disposable) service cylinders when removing refrigerant from a system. • Ensure the cylinder is free of damage which could lead to a leak or explosion. • Ensure the hydrostatic test date does not exceed 5 years. • Ensure the pressure rating meets or exceeds 400 psig. When in doubt, do not use cylinder.

NOTE: If using existing indoor coil and changing refrigerant types, ensure the indoor coil and metering device are compatible with the type of refrigerant being used. If new indoor coil is required check spec sheet or AHRI for approved coil. If system is being replaced due to compressor electrical failure, assume acid is in system. Refer to Service Procedure S-115 Compressor Burnout in service manual for clean-up procedure. 4. Ensure the filter drier paint finish is intact after brazing.
PAGE 5
Leak test the system using dry nitrogen and soapy water to identify leaks. If you prefer to use an electronic leak detector, charge the system to 10 PSIG with the appropriate system refrigerant (see Serial Data Plate for refrigerant identification). Do not use an alternative refrigerant. Using dry nitrogen finish charging the system to 450 PSIG. Apply the leak detector to all suspect areas. When leaks are discovered, repair the leaks, and repeat the pressure test.
