8.7 Potable Water Temperature
Adjustment
A thermostatic mixing valve located inside the Hurricane
®
Chinook allows for adjusting the temperature of the potable hot
water. The mixing valve is factory set to limit the maximum
water temperature to 120ºF (49°C) with a total potable hot
water demand of 1.5 GPM or less, and an incoming water
temperature of 60ºF (15ºC) or higher. If needed, this valve can
be adjusted between 75F (24°C) min. and 145F (63°C) max.
The mixing valve will compensate for temperature variations of
incoming supply water and maintain the temperature to 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 Hurricane
®
Chinook to provide hot water 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 Hurricane
®
Chinook must be removed. The mixing valve adjustment knob is
shown in Figure 8-3.
