Simple Serviceability
Raypak’s easy-to-understand user interface, including on-board diagnostics and LED operating status lights, tells the technician all he needs to
know. All service/repair components are readily accessible from the front or side for maximum installation flexibility. To enhance serviceability,
the control box is completely removable allowing total access.
