Do not operate the Oasis® Zephyr Heating System until a proper
anti-freeze (heat transfer fluid) solution has been added to the
heating system and all trapped air has been bled. An inadequate
mixture may cause system circulation problems and potential heating
system damage and/or personal injury. Use only a non-toxic,
propylene glycol-based coolant with additives recognized as safe
“GRAS” by the FDA. Refer to the anti-freeze manufacturer
recommendations for instructions for your application.
6.
Ensure that the coolant flow is adequate through the Oasis
®
Zephyr
Heating System. The flow rate through the space heating loop should
be at least 2.5 GPM. A large temperature difference between each
subsequent fan in the space heating loop (when the Oasis
®
Zephyr is
running and up to normal operating temperature) is an indication of
inadequate flow. In a properly flowing system, each fan in the space
heating loop will have an outlet temperature that is only a few
degrees cooler than the preceding fan. The temperature difference
will be larger if the fan has a higher BTU output.
7.
The Oasis
®
Zephyr should be filled and flushed prior to operation to
remove any foreign debris.
8.
Slip-on foam insulation coverings may be used over the hose fittings
to reduce heat loss.
