Before You Begin

For efficient and safe operation of the Oasis
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 Oasis 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 Oasis
· Minimize heat loss from the Oasis
· 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 Oasis
Heating System for Five Zones, shows a typical plumbing layout
for circulating heat transfer fluid from the Oasis
cabin fans, in a single loop, and back to the Oasis
