If insufficient space prevents unscrewing this third bolt, the Water Supply Tank can be
lowered by first removing the 1/4" Copper Tubing from Pump Inlet Assembly to Water Tank,
loosening the 3/4" union in front of the Water Supply Tank, and removing the side mounting
bolt which holds left upper corner of tank to cleaner frame, Tank may now be lowered,
pivoting at 3/4" union to assure adequate access to third bolt. Do not reinstall Water
Supply Tank until after new coil is installed and third bolt replaced and tightened.
Grasp the coil by the discharge elbow (a 1/2" x 4" pipe nipple may provide a better hand grip)
and the elevated pipe section where the inner and outer coil sections join, It may be neces-
sary to rap the coil a few times with a hammer to free the coil. It should then slide out
If any device such as a crowbar, etc., is used, the edge of the Heater Shell must be suf-
ficiently protected so as not to bend or distort the Heater Shell in any way to assure
proper and easy reinstallation of the replacement coil and End Bell Assembly.
Upon removal of the old coil, if the three-inch strip of insulation, Part No. 1014-2-05, comes
out with old coil, or remains at the burner end and it is to be re-used, it must be carefully
removed and set aside. With a flashlight or extension cord light, carefully clean Heater Shell
interior and inspect the Preformed Burner Drumhead Insulation for cracks or breaks. If cracked
or broken, remove all remaining parts of the Burner Drumhead and replace with a new Preformed
Burner Drumhead Insulation, Part No. 1014-1-05.
Installing Replacement Coil Assembly, Part No, 1123-6-02
Prior to installing the replacement coil assembly it is recommended the three-inch Strip Insula-
tion, Part No. 1014-2-05, be installed outside of the Stainless Steel Heat Band with care being
used to allow sufficient opening to permit insertion of 1/2" Pipe Inlet Nipple Assembly after
It is recommended that masking tape be used, a strip every six inches, to keep
insulation from protruding beyond edge of Heat Band and interfering with its sealing against
the Burner Drumhead Insulation. Strips of masking tape 1/2" or 3/4" x 12" long should be used.
Insert Coil into heater shell with end positioning tab at the bottom, being careful not to
loosen or tear insulation installed around Heat Band. When coil is in position install front
(vent end) 1/4-20 x 1/2" Hex Head Coil Alignment Bolt, but do not tighten.
Install Inlet Coil Nipple with Inlet Tee using teflon tape on all threaded fittings. Align
holes and install two remaining Coil Alignment Bolts at burner end of coil assembly and tighten
all three Coil Alignment Bolts,
Install Outlet Coil Nipple with outlet tee and reassemble both Inlet and Outlet Manifold Assem-
blies in a reverse order as in paragraphs 2 and 3 above, using teflon tape on all threaded fit-
Reposition Water Supply Tank Assembly, see paragraph 4, Note #1, and secure all fittings and
connections. Reattach-Steam Hose and Cleaning Gun to Steam Hose Outlet Port.
Prior to final assembly of cleaner it is suggested the reinstalled plumbing and components
be tested hydrostatically for leaks by running unit (fire-off) with cleaning gun valve
`open' until a full flow of water emerges from cleaning gun, then close cleaning gun valve
and check all fittings for leaks. CAUTION: Do not operate longer than ten minutes with
cleaning gun closed.
Reinstall six-inch Installation Strip, Part No, 1014-4-05 between coil and open end of Heater
Shell wedging edge of insulation strip as firmly as possible between Heater Shell and Coil,
making sure Insulation covers all exposed area of Heater Shell. Next, reinstall End Bell
Assembly, being careful to keep "match" mark and screw holes properly aligned, reinstall the
three #B x 1/2" Hex Head Slotted Screws. Check insulation for proper coverage through Heater
Reinstall Front and Rear Panels, items 10 and 12 . If Cleaner is to be shipped or stored,
