• Forleftandleftrearpiping,wraptheareawhichaccommodatestherearpiping
housingsectionwithclothtape.
• Forleftandleftrearpiping,bindtheconnectioncabletothetopofthepipewith
vinyltape.
• Forleftandleftrearpiping,bundlethepipinganddrainhosetogetherbywrapping
themwithclothtapeovertherangewithinwhichtheytintotherearpiping

(2) Temporarilyfastentheconnectioncablealongtheconnectionpipewithvinyltape.
(Wraptoabout1/3thewidthofthetapefromthebottomofthepipesothatwater
doesnotenter.)
(3) Fastentheconnectionpipetotheoutsidewallwithasaddle,etc.
(4) Fillthegapbetweentheoutsidewallpipeholeandthepipewithsealersothatrain
