1. an unfrozen high pressure area upstream of the blockage and an open faucet downstream USE OF THIS SYSTEM ON A HOT WATER HEATING SYSTEM MAY BE INEFFECTIVE NOTE Hot water heating systems use low pressure pumps More heat will be required before the warm water can seep past the ice and continue the thawing process NOTE Heat developed in the frozen section may only be 1 3 to 1 2 of the heat produced by the Hot Shot and may not be sufficient to thaw the pipe The current in the frozen section is reduced as the pipes in the hot water heating system are interconnected and offer alternative electrical paths reducing the concentrated effect of the Hot Shot NOTE Systems using cast iron radiators large iron pipes and grav ity circulation can not be thawed using the Hot Shot 1 Separate and cap all unfrozen zones 2 Separate frozen zone of the system 3 Put a non conductive non flammable insulator between pipe ends 4 Turn on heater pump and Hot Shot connected as shown be low Collect thawing water in a container When thawed shut of Hot Shot heater and system pump Quickly reconnect all pipes Check heat in all zones ol fe pi FROZEN AREA ZONE 1 USZLLALL PLIES IIA IIIT N NON FROZEN ZONE 2 da i NON CONDUCTIVE NON FLAMMABLE INSULATION HEATER O PUMP 1 Lift or remove any sheet metal pipe covers so that they are not to2. from clamp to clamp Cables coiled together Stretch out cables Do not operate with cables coiled General Wire Spring Co 1101 Thompson Avenue McKees Rocks PA 15136 412 771 6300 General Wire Spring Co 2009 www drainbrain com C HSOI 1209
