! DANGER
When there is a call for
heat, the circulation
pump in the Zephyr
sends heated fluid to
the cabin fans and
potable water heat
exchanger.

Before You Begin

For efficient and safe operation of the Hurricane
System, follow all of the recommendations in this section for proper
installation of the plumbing system. Any deviations from these must
be approved in advance by ITR.
®
The Hurricane Zephyr Heating System must use a non-toxic,
propylene glycol-based heat transfer fluid (coolant) with additives
generally recognized as safe" GRAS" by the FDA. Use of non-
propylene glycol-based heat transfer fluid can be harmful if
contamination of potable water occurs due to a leak in the heat
exchanger, which can be caused if the fresh water in the system is
allowed to freeze.
For efficient Hurricane
· Minimize heat loss from the Hurricane
· Balance the heat output for each of the zones. Balancing can be
done by adjusting the number and size of the cabin fans installed
in each space heating zone. Figure 7-2: Plumbing Hurricane
Zephyr Heating System for Five Zones, shows a typical plumbing
layout for circulating heat transfer fluid from the Hurricane
Zephyr to the cabin fans, in a single loop, and back to the
