WAT ER QUALIT Y REQUIREMENTS

USE A DRINK ING QUA LITY, COL D WATER SU PPLY ONLY

Water qua lity is of crit ical importance when
inst alling ste am produc ing equi pment of any k ind ,
particularly	high tem per ature steam producing
equ ipment.	Water that is perfectly s afe to drink is
com posed of ch emica l chara cteri stics that di rectly
affect the m etal sur faces of steam pro ducing
equ ipment.	Th ese chemica l characte ristics d iffer
great ly from regi on to regio n througho ut the U.S.
and the world.		Varying combin ation s of pH;
alkal ini ty; har dne ss; chlorid es; total di sso lved
sol ids ; an d othe r chemi cal characteristics , when
sub jecte d t o high tem perature s, will cause wate r to

have a te ndency to eithe r scale or corrod e.
Alto- Shaam has consul ted wit h people who
underst and the properti es of wa ter i n ord er to
provide wate r qua lit y standards that mee t the
broade st possible	ra nge of acceptabl e water quality
requireme nts to hel p prote ct your i nvestme nt.
We stron gly ur ge water		testing to ascer tain th e
wat er quality on	sit e prior	to the instal lati on o f any

steam produ cing equip men t. Si nce wate r qua lity is an import ant issue , Alto-Sh aam is comm itte d to provide as m uch i nformat ion as possib le to he lp protect the invest ment made in this equi pment.

A CombiGuard™ Water Filtra tion Sys tem can be purchased as an option for inst allation o n th e Comb ither m oven. This filter, when pr operly

inst alled, maintained, and com bine d with the required levels of ste am gen era ting equipmen t maintena nce, will help lessen the af fect water has on meta l surfaces . It will not, how ever, p rovide complete protecti on against all water damage fr om region to regi on.

Due to the com plexity of water chemistr y, it is important to underst and that water qual ity plays a sign ificant role in the longev ity of steam pr odu cing equipment. Water quality and required maint enanc e of stea m gener ating equipment is th e dir ect respons ibility of the owner/ operator. D amage

incu rred as a direct result of poor w ater quality and/ or surfaces affected by water quality is also the respons ibility of the owner/ operator. D amage due to water quality that does not mee t th e m inimum standards show n bel ow is not covered under the Alto-S haam Combithe rm warranty.

Alto-Shaam will con tinue our efforts to pro vide viable solutions to ease the impact of wa ter quality as it relates to steam generating equipm ent.
