The electrical winterization kit consists of a heat ex-
changer, control box, coolant pump, thermostat and
accessories. The primary purpose of the kit is to
maintain the set in a heated condition, at any ambient
temperature from 125°F. to -65°F. to enable it to
accept 75% of rated load in one step within 20 seconds
fter starting action is initiated. The coolant temp-
erature is thermostatically
controlled at 130° F. to
150°F. The kit can also be used to warm the Genera-
tor Set for initial starting within 5 hours at any ambi-
ent temperature down to -65°F. Power for operation
of the kit may be obtained from any power source that
supplies 205 to 240 volts at 50, 60 or 400 HZ single
phase. For electrical winterization kit operating
instructions refer to f i g . 2 - 1 1 .

For wiring information, see f i g u r e 4 - 6 . To perform
initial installation of the electric winterization kit,
see f i g u r e s 1 - 2 3 , 1 - 2 6 o r 1 - 2 7 , a n d 4 - 7 and proceed
as follows:
a. Remove plate from redr housing, adj scent to
con~rol cubicle ( f i g u r e 1 - 2 ) adj scent to Fault indica-
tor panel, and retain attaching hardware for instal-
lation of the electric winterization control box ( 4 5 ,
f i g .
4 - 7 ) .
~. Refer to p a r a g r a p h 3 - 4 1 and drain cooling
system.
c.
Remove two plugs from engine oil pan heat
exc%anger.
Retain plugs.
~. Remove plugs from engine thermostat housing
and engine oil cooler. Retain plugs.
e. Install kit as described and illustrated in
f i g u r e
1 - 2 3 using installation sequence 68 through 1
of
f i g u r e
4 - 7 except as noted in (1) through (3) below
when fuel burning winterization kit and electric win-
terization kit are used together. (See sheet 2 of
f i g u r e 4 - 7 . )
(1) Remove plug ( 6 4 , f i g . 4 - 1 ) from three way
valve (67) and install nipple ( 6 9 , f i g . 4 - 7 ) into three
way valve ( 6 7 , f i g . 4 - 1 ) . Connect hose ( 7 0 , f i g . 4 - 7 )
between elbow (13) and nipple (69).
(2) Remove plug ( 4 9 , f i g . 4 - 1 ) and install
nipple ( 1 8 , f i g . 4 - 7 ) . Connect hose (41) between
nipple (18) and nipple (3 I).
(3) Remove plug ( 1 9 , f i g . 4 - 7 ) and install
elbow ( 4 3 , f i g . 4 - l ) . Connect hose (47) between
lbow (43) and elbow (50).
~. Refer to
p a r a g r a p h
2 - 3 and close coolant shut-
off cocks and service radiator.
g. Set electric heater control box POWER switch
to OFF position.
h. Connect 50/60 or 400 Hz single phase power
cab~e from an external 208 to 240 volts power source
to J49 of kit ( f i g u r e s 1 - 2 6 o r 1 - 2 7 ) .
Perform
all daily checks before operation preven-
tiv; maintenance checks and services listed in table 4-3.
Refer to p a r a g r a p h 4 - 2 0 .
~. Refer to
p a r a g r a p h
2 - 2 4 and energize the
electric winterization kit and check kit operation
as follows:
(1) Audibly check that kit coolant ~, T. P is
operative.
(2) Check complete kit installation to assure
there are no coolant leaks.
(3) Allow five minutes for warmup and then
place hand near the heat exchanger. Determine that
the heat exchanger is heating.
WARNING
Do not attempt to hold the hand in contact
with the heat exchanger.
NOTE
To determine that each heating element
is functioning, disconnect electrical
lead from one element and check as in
step (3) above.
Reconnect element and
disconnect remaining element and check
as ir, step (3) above.
(4) Slightly 100S,W the hose coupling on the
outp~t end of the heat exchanger (left side, facing
the engine radiator).
Coolant, under pressure
should flow from the union.
(5) Tighten the coupling when the test is
complete.

sys~em.
b. Set electric control box POWER switch to
OFF position and remove power cable from J49.
c.
Remove kit by proceeding in reverse order of
ins~allatiori procedure using f i g u r e 1 - 2 4 and removal
sequence of 1 through 69 of f i g u r e 4 - 7 except as
