Do not use hot water during commissioning or maintenance of the System. It is possible that if a hot water tap is used, high levels of factory preservative, chlorine or MAYTAG MC1 Cleaning Solution will enter the hot water tank and cause personal injury, illness and/or death. It is recommended to close the hot water inlet valve during commissioning or maintenance of the System and to reopen the hot water inlet valve at the end of the procedure.
When filling System, fill slowly and watch for leaks to avoid excessive water dripping onto floor.
During this procedure DO NOT open the Bypass Valves as this will allow potentially contaminated water into the household distribution system. Contaminated water may lead to personal injury and/or death.
Chlorine bleach must be less than 3 months old. The active percentage reduces with time.
This procedure does not disinfect all of the household lines. It is strongly recommended that all of the lines are sanitized as water left in pipes may be microbially unsafe.
When treating surface water sources a maximum prefilter mesh size of 30 micron is required. Failure to provide this level of prefiltration may lead to System damage. A damaged System will not perform effectively, endangering the homeowner or occupant through possible serious personal injury and/or even death.
Do NOT allow the preservative (plumbing antifreeze) to drain onto the ground, into a septic bed, storm sewer or any body of water. Check the plumbing antifeeze manufacturers directions and warnings for more information.
