Ground-Water Heat Pump Applications, Cont’d.
Water Coil Low Temperature Limit Setting -
For all open
loop systems, CXM/DXM2 JW3 Jumper (LT1) should
never
be clipped to avoid freeze damage to the unit, and voiding
your warranty. See “Low Water Temperature Cutout
Selection” in this manual for details on the low limit setting.
NOTICE! Ground-water applications for commercial
buildings with more than 2-3 units should include a
plate frame heat-exchanger to isolate the heat pumps
from the ground-water and confine heat exchanger
cleanings to one location and lessen maintenance. Direct
use of ground-water may increase the frequency of heat
pump maintenance and may shorten life expectancy.
