Installation Manual for Hurricane® Zephyr™ HW Heating System
2 Remove the front cover of the Hurricane
®
Zephyr, also remove
the cover of the control board to provide access to the
circulation pump jumper on the circuit board See diagram
below. Using a self-priming pump, fill the system through the
filler port (1/2" hose barb connection) located at the bottom of
the tank with the proper mixture of propylene glycol-based
antifreeze/heat transfer fluid. Some manufactures refer to heat
transfer fluid as boiler anti-freeze; the solution is often pre-
mixed and should not be diluted. See the manufactures
recommendations for dilution requirements if the fluid is not
pre-mixed.
3 When the fluid starts to run into the overflow bottle, turn off
filling pump and place the pump circulation jumper on the
control board circuit board onto both pins. The Hurricane
®
Zephyr internal pump will run and circulate fluid through the
entire system. The fluid level in the overflow bottle will drop as
the air in the system is displaced with fluid. Turn on the filling
pump and refill the overflow bottle to the "Minimum when cool"
level.
4 When this level is reached, turn OFF the filler pump, and keep
the jumper in place until the system is purged of air and the
coolant level in the overflow bottle does not change.
5 Once the system has been purged of air, remove the jumper
from both pins and place it on one pin. The jumper is stored in
this position. This Bypass Switch should remain off during
normal operation. It is only used to fill and purge the system.
The shut-off valve on the filler hose must be in the closed
position when the system has been filled.
