9.9 Domestic Water Temperature
Adjustment
A thermostatic mixing valve located under the top access panel
®
on the Oasis Zephyr allows temperature adjustment of the
potable hot water. This mixing valve is factory set to limit the
maximum water temperature to 120ºF (49°C) with a hot water
demand (flow-rate) of 1.0 GPM or less, and an incoming water
temperature of 60ºF (15ºC) or higher. If needed this valve can
be adjusted in a range from 75F (24°C) to a maximum of 145F
(63°C).
The mixing valve will compensate for temperature variations of
incoming supply water and maintain the temperature at which
it is set. However, in some cases, the temperature of the
incoming water and the flow-rate demand of multiple faucets
may limit the ability of the Oasis
at the temperature setting of the mixing valve, even if the
mixing valve is set to its maximum. This is a normal operating
characteristic of any on-demand, continuous hot water system
that does not rely on heat retained within a stored volume of
water. In this situation the temperature of the hot water may
be increased by lowering the flow at the faucet and shower
head.
To adjust the mixing valve, the top cover of the Oasis
must be removed. The mixing valve adjustment knob is shown
in Figure 9-1.
