S e c t i o n I I I . E L E C T R I C W I N T E R I Z A T I O N K I T4 - 1 7 . G e n e r a l .The electrical winterization kit consistsof a heat ex-changer, control box,coolant pump, thermostat andaccessories. The primary purpose of the kit is tomaintain the set in a heated condition, at any ambienttemperature from 125°F. to -65°F.to enable it toaccept 75%of rated load in one step within 20 secondsfter starting action is initiated. The coolant temp-erature is thermostaticallycontrolled at 130° F. to150°F. The kit can alsobe used to warm the Genera-tor Set for initial starting within 5 hours at any ambi-ent temperature down to -65°F. Power for operationof the kitmay be obtained from any power source thatsupplies 205 to 240volts at 50,60 or 400HZ singlephase. For electrical winterization kit operatinginstructions refer to f i g . 2 - 1 1 .4 - 1 8 . I n s t a l l a t i o n .For wiring information, see f i g u r e 4 - 6 . To performinitial 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 andproceedas follows:a. Remove plate from redr housing, adj scent tocon~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 coolingsystem.c.Remove twoplugs from engine oil pan heatexc%anger.Retain plugs.~. Remove plugs from engine thermostat housingand engine oil cooler. Retain plugs.e. Install kit as described andillustrated inf i g u r e 1 - 2 3 using installation sequence 68 through 1of f i g u r e 4 - 7 except as noted in (1) through (3) belowwhen fuel burning winterization kit andelectric win-terization kit are usedtogether. (See sheet 2 off i g u r e 4 - 7 . )(1)Remove plug( 6 4 , f i g . 4 - 1 ) from three wayvalve (67) and install nipple ( 6 9 , f i g . 4 - 7 ) into threeway 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 installnipple ( 1 8 , f i g . 4 - 7 ) . Connect hose (41) betweennipple (18) andnipple (3 I).(3)Remove plug ( 1 9 , f i g . 4 - 7 ) and installelbow ( 4 3 , f i g . 4 - l ) . Connect hose (47) betweenlbow (43) and elbow (50).~. Refer to p a r a g r a p h 2 - 3 andclose coolant shut-off cocksand service radiator.g. Set electric heater control box POWER switchto OFFposition.h. Connect 50/60 or 400 Hz single phase powercab~e from an external 208 to 240 volts power sourceto J49 of kit ( f i g u r e s 1 - 2 6 o r 1 - 2 7 ) .Performall 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 andenergize theelectric winterization kit andcheck kit operationas follows:(1) Audibly check that kit coolant ~, ‘T. P isoperative.(2) Check complete kit installation to assurethere are no coolant leaks.(3) Allow five minutes for warmup and thenplace hand near the heat exchanger. Determine thatthe heat exchanger is heating.WARNINGDo not attempt to hold the hand in contactwith the heat exchanger.NOTETo determine that each heating elementis functioning, disconnect electricallead from one element and check as instep(3) above.Reconnect element anddisconnect remaining element and checkas ir, step (3) above.(4)Slightly 100S,W the hose coupling on theoutp~t end of the heat exchanger (left side, facingthe engine radiator).Coolant, under pressureshould flow from the union.(5) Tighten the coupling when the test iscomplete.4 - 1 9 . R e m o v a l .To remove the electric winterization kit, seef i g u r e 4 - 7 and proceecl as follows:a. Refer to p a r a g r a p h 3 - 4 1 and drain coolingsys~em.b. Set electric control box POWER switch toOFF position and remove power cable from J49.c.Remove kit by proceeding in reverse order ofins~allatiori procedure using f i g u r e 1 - 2 4 and removalsequence of 1 through 69 of f i g u r e 4 - 7 except as4 - 1 1
