4.4 COOLING SYSTEM
The liquid cooling system is a closed system which will operate for years without maintenance. The coolant
level should extend into the coolant reservoir, with the heat exchanger full for optimum cooling. This will
provide protection to 5° C (41
˚
F) for operation and -10
˚
C (14
˚
F) for storage.
The coolant manufacturer is Koolance (www.Koolance.com). Koolance LIQ-702 (orange color) consists of
25-30% propylene-glycol with the balance of distilled water. The amount of fluid is ~300ml (the volume of
the reservoir). Maximum fluid pressure is 15.6 Psi.
Quick-disconnect leak-proof connectors are incorporated to allow for removal of modules and major system
components with no leakage of fluid. In the event of a leak, the liquid will safely exit one of the corners
before any damage is done to any electrical components of the amp. If the reservoir is emptied, the flow
sensor will detect a lack of flow and shut the amp down.
If coolant is removed from the system for any reason, the pump should not be activated; damage to the pump
can occur if it is run without fluid.
See the Manufacturer’s Safety Data Sheet for safe handling and clean-up. Safety Data Sheet, reference:
