Antifreeze —
1.5
drop below 40 F or where piping will be routed through areas
0.5
subject to freezing, antifreeze is needed.
0.9
1.5
Alcohols and glycols are commonly used as antifreeze
0.7
agents. Freeze protection should be maintained to 15 F below
1.3
2.1
the lowest expected entering loop temperature. For example, if
1.1
the lowest expected entering loop temperature is 30 F, the leav-
1.7
ing loop temperature would be 22 to 25 F. Therefore, the freeze
3.2
protection should be at 15 F (30 F – 15 F = 15 F).
1.3
2.6
4.1
IMPORTANT: All alcohols should be pre-mixed and
1.7
pumped from a reservoir outside of the building or
3.2
5.2
introduced under water level to prevent fuming.
0.9

Calculate the total volume of fluid in the piping system. See
1.2
Table 25. Use the percentage by volume in Table 26 to deter-
2.5
4.1
mine the amount of antifreeze to use. Antifreeze concentration
should be checked from a well mixed sample using a hydrome-
ter to measure specific gravity.
FREEZE PROTECTION SELECTION — The 30 F FP1
factory setting (water) should be used to avoid freeze damage
to the unit.
Once antifreeze is selected, the JW3 jumper (FP1) should
be clipped on the control to select the low temperature (anti-
freeze 13 F) set point to avoid nuisance faults.
