Safety Instructions
The MAYTAG Whole Home Water Filtration System has been designed and tested to offer
reliable service, provided it is installed by a MAYTAG Services Qualified Service Technician
and is operated, maintained, and tested in strict accordance with the safety instructions contained
in this manual.

Operational Safety
• The MAYTAG Whole Home Water Filtration System is under pressure during use and
precautions must be taken.
• This device is designed to operate on a 120VAC/15 Amp/ 60Hz line. Do not modify the plug
on the power cord. If the plug does not fit the electrical outlet, have a proper outlet installed
by a qualified electrician.
• To avoid System damage: Ensure that a Stainless Steel Prefilter or Carbon Prefilter is in place
during operation of the System. In the absence of an Internal Prefilter, abrasive damage to the
System may occur. A damaged System may permit contaminated water to enter the household
distribution system causing illness. Irreversible and premature fouling of the System may also
occur resulting in System replacement at the owner’s expense.
Service and Maintenance Safety
• To avoid electric shock: Disconnect the AC power from the MAYTAG Whole Home Water
Filtration System before servicing the controller; do not remove the controller cover while
System is in use. Only MAYTAG Services Qualified Service Technicians should attempt to
service the controller.
• Important: The MAYTAG Whole Home Water Filtration System must be kept in a wetted
condition. Once installed or during service and maintenance activities, do not allow the
System to sit completely drained for extended periods (greater than 12 hours). Failure to do
so may damage the System and cause contaminated water to enter the household.
MAYTAG Whole Home Water Filtration System Owners Manual MA1-5
November 2003

The MAYTAG Whole Home Water Filtration System must be kept wet at all times after
installation. Failure to do so may cause System to dry and become damaged, which may
lead to personal injury, and/or physical damage and will void any warranty.
Winter Storage
• The MAYTAG Whole Home Water Filtration System will be damaged if frozen. The System
must be winterized according to the Winterization Procedure by a MAYTAG Services
Qualified Service Technician.
The MAYTAG Whole Home Water Filtration System must be winterized prior to
temperatures falling below 0°C (32 F). Failure to do so may cause System to dry, freeze
and become damaged, which may lead to personal injury, and/or physical damage and
will void any warranty.
Other Safety Precautions
• Do not plug in the Controller transformer if there is water on electrical wiring or the power
supply.
• Always shut off water flow and release water pressure before cleaning or maintaining the
System.
• The System is intended for indoor use only. The power supply and controller must not be
exposed to weather elements.
• A MAYTAG Services Qualified Service Technician must perform an Integrity Test at least
once a year.
The MAYTAG Whole Home Water Filtration System must be;
• tested annually using the integrity test.
• operated with either a Carbon or Stainless Steel Prefilter.
Failure to do so may cause System to become damaged, which may lead to personal
injury, and/or physical damage and will void any warranty.
Emergency Bypass Safety (if installed where required by local plumbing codes)
Some Systems will have a bypass valve installed. If a bypass valve is installed, your System
piping will look like Photo 1. Follow these safety precautions if your System has been installed
with an emergency bypass valve.
MAYTAG Whole Home Water Filtration System Owners Manual MA1-5

p
Bypassing the MAYTAG Whole Home Water Filtration System will result in unfiltered
water entering the household distribution system. This water may be biologically unsafe
and drinking this water could result in illness or death. Exercise caution in bypassing the
System. Do not drink water from the System while the System is in bypass mode.
If the System has been operated in bypass mode and if water is being drawn from a well
or surface water source, the household distribution system should be re-disinfected once
returned to filtration mode.
If the System is in bypass mode, the controller must be unplugged. Failure to do so
may cause System to dry and become damaged, which may lead to personal injury,
and/or physical damage and will void any warranty.
Photo 1.
A bypass system is not required for proper operation of the MAYTAG Whole Home Water
Filtration System, however some local plumbing codes may require a bypass. If the System is to
be equipped with a bypass, the procedure below may be followed to provide water in an

emergency or System malfunction.

Bypass Procedure
1. Close the Inlet and Outlet ball valves (turn handles clockwise). Ball valves are in the
closed position when the handle is positioned perpendicular to the water pipe. (See
Photo 2a and 2b on previous page.)
2. Open Bypass Valve (turn handle counter-clockwise).
3. Unplug controller.
4. To return to filtered water service, in the order listed;
• close bypass valve (turn handle clockwise)
• open inlet and outlet ball valves (turn handles counter-clockwise)
• plug in controller

Startup of a new MAYTAG Whole Home Water Filtration
System
Once the MAYTAG Services Qualified Service Installer has completed the new System
installation, the owner should thoroughly flush the filtration system before using. Simply open a
nearby water tap and allow to run for about 1 hour. Ensure that the drain is open and unobstructed
and able to accommodate the flow. Do not leave flowing water tap unattended. This will remove
any residual preservative from the new System.
Sanitizing Your Household Distribution System
If your new MAYTAG Whole Home Water Filtration System is being used to filter water from
sources other than a municipal drinking water supply, your household drinking water distribution
system should be sanitized prior to use. Please see your MAYTAG Services Qualified Service
Installer or MAYTAG Customer Care for details.
Maintenance Schedule
All service and maintenance is to be performed by a MAYTAG Services Qualified Service
Technician. An annual integrity test must also be performed by a MAYTAG Services Qualified
Service Technician. This annual test is required as part of the 5 year limited prorated membrane
warranty.
If the MAYTAG Services Qualified Service Technician determines that the System has a high
degree of debris causing a reduction in System flowrate, the number of visits per year may be
increased by MAYTAG to ensure that the System stays within operational limitations set by
