Mounting the Heat Exchanger
to All Models
NOTE:
The units are very top heavy when attached only at the
return union. Make sure that the unit is well supported during fit
up. Mounting of the RXLD Models requires more than one
person.
Using thread seating compound install the included PEX lined
steel nipples into the side loop connections. Thread the return
fitting onto the lower PEX nipple and tighten the union nut firmly
by hand, see Figure 7. Set the heat exchanger on the return
fitting, see Figure 8. Then connect the supply fitting and rotate it
so that the pipe contacts the pump., see Figure 9. It may be
necessary to make a preliminary cut on the pipe to allow this.
Mark the pipe at the top of the pump and add 5/8” for solder
socket engagement, see Figure 9. Remove and cut the pipe at
the second mark. Reinstall the supply side assembly inserting
first into the pump and then connect it at the union, see
Figure 10. Make any adjustments needed to the length of the
support leg on units so equipped.
