1.
Utilization Range “A” in accordance with ARI Standard 110.
2.
The water pressure must be great enough to overcome the pressure drop of the condenser and the condenser water piping.
3.
Although the water side is only leak tested for 150psig, the maximum water-side working pressure of the condenser is 450 psig.
Class 150 fittings in the unit’s condenser water piping are good for 300 psig. For 300 psig applications, a sealing material (Lock-
tite or equivalent) must be applied to all threaded connections to assure a leak-tight installation. The water regulating valve acces-
sories are limited to a maximum 150 psig.
4.
The limitation for entering condenser water temperature will vary with condenser water GPM.
THIS PRODUCT MUST BE INSTALLED IN
STRICT COMPLIANCE WITH THE ENCLOSED
INSTALLATION INSTRUCTIONS AND ANY
APPLICABLE LOCAL, STATE, AND NATIONAL
CODES INCLUDING BUT NOT LIMITED TO,
BUILDING, ELECTRICAL AND MECHANICAL
CODES.
