Adiabatic Pre-Cooler Pad Removal
NOTICE: To prevent excessive degradation, do not attempt to remove the adiabatic pre-
cooler pads wet.
Removal of adiabatic pre-cooler pads has been designed as a tool-free operation for quick access for maintenance and to
access the interior of the unit for inspection. To remove the adiabatic pre-cooler pads:
1.
Remove the adiabatic pre-cooler pad wedge by removing two plastic knobs per wedge assembly. 4-fan units will
have two pad wedges, 6-10 fan units will have four pad wedges, 12-fan units will have six pad wedges, and 14-18
fan units will have eight pad wedges. Refer to Figure 6 for typical wedge locations.
2.
Reposition the adiabatic pre-cooler pad wedge and grip both sides of the pad. Lift the pad directly up and then
towards you.
3.
Reinstall the adiabatic pre-cooler pads in the reverse order.
a.
Always re-install the adiabatic pre-cooler pads with the blue protective coating on the outside face. Always
ensure that the re-distribution section of the pad is at the top of the unit per Figure 7.
