KLR 10 Installation Manual
2.5
ESTABLISH A PLAN TO ROUTE THE SENSE LINES
The sense lines must be installed through the aircraft structure with the following limitations:
Do not remove hose end caps until final connector installation. This keeps contamination from
entering the sense lines during installation.
A minimum bend radius of 4" for the lines must be observed.
Attach the sense lines at regular intervals by means of suitable clamps.
Do not clamp sense lines at the end fittings.
Use AN931 Grommets (preferred) or bulkhead fittings where the sense lines pass thru bulkheads.
Engineering data may be required if installing on a pressurized aircraft.
Keep the sense lines well clear of any moving controls or cables.
Refer to AC43.13-1B chapter 12 section 4 for instructions on replacing/installing new pitot static lines.
2.6
ESTABLISH A PLAN FOR THE ELECTRICAL POWER:
The KLR 10 requires less than ¼ amp (250 mA) of electrical power within its acceptable voltage range of
10-28 VDC. Our recommendations would be to have the KLR 10 get power from the avionics bus through
an on/off switch in series with the positive lead for the control module (this would offer some protection
from surges during starts and the on/off switch would enhance operational flexibility).
For additional information please refer to AC43.13-1B Chapter 11, which has a wealth of information on
wire, switches, loads, etc., also AC43.13-2B Chapter 2 paragraph 207 is useful.
2.7
OPTIONAL PROBE HEAT INSTALLATION:
The optional heated probe requires 7.8 amps of electrical power at 12 or 24VDC.
Determine the size of wire required from AC43.13-1B Chapter 11 Section 5, (12VDC in free air #14 wire
will be adequate for runs up to 20' & for 24VDC in free air #16 wire will be adequate for runs up to 25').
As an added precaution to prevent interference with other aircraft systems use MIL Spec. shielded wire.
Electrical cable/wire must be installed such that the risk of mechanical damage and/or damage caused by
fluids, vapors, or sources of heat, is minimized. Route as far away as possible from any instrument,
system or wiring that may be effected (i.e. compass/flux gate, antenna or antenna coax).
We recommend that you use a Mil. Spec. DC switch with silver contacts rated for twice the required
amperage (i.e. Eaton 8500K9, MS24523-22 SPST switch).
AC43.13-1B Chapter 11 has a wealth of information on wire, switches, loads, etc. also AC43.13-2B
Chapter 2 paragraph 207 is useful.
