Kohler PAA-225575 Installation Instructions

Remote Radiator Assembly Kits with 12-Volt Suction Fan
PAA-225575 (15CCO) & PAA-225579 (20CCO)
These kits along with the remote radiator specifications,
allow the generator set radiator to be mounted in a
location remote from the generator set.
For best performance, it is recommended that the
radiator is mounted at the same level as the generator
set. If the radiator is mounted at a level lower than the
generator set, use of a surge tank is required (not
supplied). Recommended maximum radiator mounting
distance from generator set is 10 feet.
Radiator mounting location should provide adequate air
flow (1365 cfm [38.65 cmm]) to allow proper cooling.
(See Figures 1 and 2 for radiator mounting dimensions
and air flow direction information.) Use coolant hoses
that meet SAE standard—SAE 20R4 (minimum) to
connect remote radiator to generator set.
WARNING
Accidental starting.
Can cause severe injury or death.
Disconnect battery cables before working on
generator set (negative lead first and reconnect it
last).
Accidental starting can cause severe injury or
death. Disconnect battery cables (remove negative
lead first and reconnect it last) to disable generator set
before working on any equipment connected to
generator. The generator set can be started by remote
start/stop switch unless this precaution is followed.
INSTALLATION INSTRUCTIONS
RV Generator Sets
INSTALLATION
1. Move START/STOP switch to STOP position.
Remove generator set battery cables, negative
lead first.
2. Mount the remote
(A-225575—15CCO) or (A-225579—20CCO).
Connect radiator to generator set engine with
coolant hoses (not supplied). Secure hoses with
hose clamps (not supplied).
NOTE
When routing coolant hoses, avoid sharp bends
that restrict coolant flow. Avoid locating hoses
against abrasive or hot surfaces, or sharp edges.
3. Remove controller cover. Drill a 0.219-in.
(5.6 mm) diameter hole in the controller base
plate at the location shown in Figure 3. (On later
models, plug mounting hole is provided.)
NOTE
Controllers on early 15CCO and 20CCO models
may not have hole required for radiator fan
harness connector. In these cases, a 0.440-in.
(11.2 mm) diameter hole must be drilled in the rear
of controller at the location shown in Figure 3. (On
later models, plug mounting hole is provided.)
NOTE
Observe all appropriate safety procedures for use
of power tools when drilling holes. Remove all
burrs and metal chips from the work area before
continuing installation procedure.
4. Install K30 relay (259391) with 10-32 x 0.500-in.
R.H.M. screw (X-50-1) and whiz nut (X-6210-1).
5. Install grommet (200705) in 0.44-in. (11.2 mm)
diameter hole (early models only).
