9.4-8 HANDLING, SERVICE & MAINTENANCE
STORAGE
During long periods of non-use, the porous panel membranes may dry
out, which could cause uneven uid ow during subsequent operation.
Perform the Pre-Flight Inspection every 30 days to keep the porous panel
membranes wetted.
To prepare the TKS Ice Protection System for yable storage, ll the uid
reservoir and operate the system on MAX to ensure all air is completely
purged from components and plumbing. Re-ll the uid reservoir after
purging the system.
SERVICING
Ice Protection Console Tank
The uid reservoir is serviced through the ller cap in the console between
the two crew seats. The tank is drained by removing the threaded plug
located on the bottom of the fuselage. The reservoir is vented through the
ller cap. The uid level is shown on a level indicator within the tank.
Ice Protection Cargo Compartment Tank
The uid reservoir is serviced through the ller tube and cap on the
tank located in the forward end of the forward bay of the External Cargo
Compartment. The tank is drained by pushing and turning the quick-drain
valve located on the reservoir sump, which is accessed by removing the
access cover in the protecting bulkhead. A short length of exible tubing will
be necessary to convey the uid out of the cargo compartment door.
The
uid level is shown on the sight-tube on the left-hand side of the tank.
Porous Panels
Periodically clean the porous panels with mild soap and water using a clean
lint-free cloth. Isopropyl alcohol may be used to remove oil or grease.
System Priming
In the event of loss of prime, the windshield pump may be activated to purge
the system of any air between the main metering pumps and the uid tank.
It is unlikely that the system will experience a loss of prime except when
the uid tanks are intentionally run dry. If, after multiple purging attempts,
insufcient ice protection uid is evident during the Pre-Flight Inspection, the
ice protection system must be purged in accordance with the KODIAK 100
Airplane Maintenance Manual.
CAUTIONS:
• Use only approved ice protection uids, “Kilfrost TKS Sustain” or uid
conforming to British Specication “DTD 406B.”
• Certain solvents may damage the panel membranes. Use only soap
and water, isopropyl alcohol, or ethyl alcohol to clean the panels. Do
not wax the leading edge porous panels.
CAUTION: Do not ll beyond the MAX FILL mark. Spillage may occur.
