Polar Bear III 10 Degree Installation Manual 
9910030 Rev B 

Introduction 

Polar Bear® III offers a straight-forward roof mount design that combines features, service and reliability 
into a single platform solution. The system components, delivery, and installation process are designed 
together to deliver a lower total installed cost and better service experience. The design emphasizes 
features to improve construction performance including: 
 

 

Just three major components, light-weight and easy to move 

 

Pre-assembled bolts to quickly mount Ballast Trays 

 

Single-module tilt-up feature that facilitates must-have access to roof, wiring and maintenance 

 

Document Objective 

This installation manual has been put together to assist in the proper steps required to build a Polar 
Bear III 10 Degree flat roof mount system array. The manual covers a best-practice order of assembly for 
the construction of the roof mount array and contains detailed notes and tips for a successful assembly. 
 

Safety Overview 

Safety is an essential part of every photovoltaic (PV) installation and every construction site. It is 
imperative to plan ahead for any safety concerns and hazards to promote safe work practices during 
installation. This section does not claim to address or support all safety concerns that may arise during 
the installation of PanelClaw mounting systems or any other aspect of the work being performed. Before 
beginning work, installers should refer to all local and federal safety, health, and regulatory 
requirements to assure compliance. Refer to OSHA Part 1926 and its related Subparts for federal 
construction related regulations and standards.  
  
The section in 

Appendix A: Safety

 outlines some of the obvious / major hazards that could exist during 

the installation of PanelClaw products, and are divided to bring a level of clarity to such hazards. Some 
sections do not apply to all PanelClaw product lines and such exclusions are noted within each section.  
 

  PRIOR TO INSTALLATION, READ THE SAFETY PROVISIONS ATTACHED IN 

APPENDIX A

 AND REVIEW 

THE INSTALLATION MANUAL IN ITS ENTIRETY. 

 An annual corrosion inspection and potential corrective actions are required to maintain product 

warranty. Visible surface red rust on galvanized steel components must be locally coated with a 
commercially available galvanized paint or coating to maintain product warranty.
