EPA Regulations

Important: The United States Environmental 

Protection Agency (EPA) has issued various 

regulations regarding the introduction and 

disposal of refrigerants in this unit. Failure 

to follow these regulations may harm the 

environment and can lead to the imposition 

of substantial fines. Because regulations may 

vary due to passage of new laws, we suggest a 

certified technician perform any work done on 

this unit. Should you have any questions please

National Codes

This product is designed and manufactured to permit 

installation in accordance with National Codes. It is the 

installer’s responsibility to install the product in accordance 

with National Codes and/or prevailing local codes and 

regulations.

The heating and cooling capacities of the unit should be 

greater than or equal to the design heating and cooling 

loads of the area to be conditioned. The loads should be 

calculated by an approved method or in accordance with 

ASHRAE Guide or Manual J - Load Calculations published 

by the Air Conditioning Contractors of America.

Obtain from:

American National Standards Institute 

www.ansi.org

System design and installation should also, where 

applicable, follow information presented in accepted 

industry guides such as the ASHRAE Handbooks. The 

manufacturer assumes no responsibility for equipment 

installed in violation of any code or regulation. The 

mechanical installation of the packaged roof top units 

consists of making final connections between the unit and 

building services; supply and return duct connections; and 

drain connections (if required). The internal systems of 

the unit are completely factory-installed and tested prior to 

shipment.

Units are generally installed on a steel roof mounting 

curb assembly which has been shipped to the job site for 

installation on the roof structure prior to the arrival of the 

unit. The model number shown on the unit’s identification 

plate identifies the various components of the unit such as 

refrigeration tonnage, heating output and voltage.

Carefully inspect the unit for damage including damage 

to the cabinetry. Any bolts or screws which may have 

loosened in transit must be re-tightened. 

In the event of damage, the receiver should:

1.  Make notation on delivery receipt of any visible 

damage to shipment or container.

2.  Notify carrier promptly and request an inspection.

3.  In case of concealed damage, carrier should be 

notified as soon as possible-preferably within 5 days.

4.  File the claim with the following supporting 

documents:

a.  Original Bill of Lading, certified copy, or 

indemnity bond.

b.  Original paid freight bill or indemnity in lieu 

thereof. 

c.  Original invoice or certified copy thereof, 

showing trade and other discounts or 

reductions.

d.  Copy of the inspection report issued by carrier 

representative at the time damage is reported 

to the carrier. The carrier is responsible for 

making prompt inspection of damage and for 

a thorough investigation of each claim. The 

distributor or manufacturer will not accept 

claims from dealers for transportation damage.

NOTE: When inspecting the unit for 

transportation damage, remove all packaging 

materials. Recycle or dispose of the packaging 

material according to local codes.

Pre-Installation Checks

Carefully read all instructions for the installation prior 

to installing unit. Ensure each step or procedure is 

understood and any special considerations are taken into 

account before starting installation. Assemble all tools, 

hardware and supplies needed to complete the installation. 

Some items may need to be purchased locally.
