OWNER INFORMATION

General

Thank you for choosing an Aquamor® UF System Controller. Designed and assembled in the USA, the controller is the command center of your Ultrafiltration (UF) System. It runs the flush valve on a schedule you set, so your UF membrane stays clean with no daily effort from you.

The controller is a low-voltage electronic timer. It connects to a power adapter and to one or two flush ball valves. On the schedule you program, it opens each valve for a set time to flush the membrane, then closes it again.

This manual covers the controller only. It walks you through four tasks, in order:

  1. Connect the power adapter.
  2. Connect the flush ball valve (or two valves on a two-stage system).
  3. Program the flush schedule.
  4. Run a manual flush.

The first three connection steps are done once, at install. Programming and manual flushing are things you can do any time. Each step is labeled so you know whether it is an install task or an everyday task. Please read this manual completely before installing or operating the controller, and retain it for future reference.

Technical Assistance

If you have any problems with the installation or operation of your UF System Controller, please contact Aquamor Customer Service. Customer Service is open Monday through Friday, 8 am to 5 pm Pacific.

IMPORTANT SAFETY INFORMATION

Read all instructions before use. Save these instructions. The UF Controller runs on household power and is installed next to plumbing. Read these safety messages before you connect or operate it. They appear again, in shorter form, at the exact step where each hazard applies.

WARNING

Electric shock. Mains voltage is present at the power adapter and its cord. Contact can cause serious injury or death. Connect the adapter only to a properly grounded outlet. Do not use a damaged cord or plug.

WARNING

Water and electricity. This controller is used near plumbing. If the adapter, cord, or plug touches water, you can get a shock. Keep the adapter, cord, and plug dry and off the floor. Do not immerse them. Mount the controller above any place water could spray or pool.

WARNING

Ground-fault protection. A ground fault near water can cause electric shock. Aquamor recommends plugging the adapter into a GFCI-protected outlet and testing the GFCI per its instructions.

CAUTION

Cord routing. A cord run near hot surfaces or pinch points can be damaged, leading to shock or fire. Route the cord away from hot surfaces and sharp edges. Do not pinch it under the bracket or in a cabinet door.

INSTALLATION
For the Installer

The Controller and Its Ports

The Aquamor UF Controller works with both a single-stage UF System and a two-stage UF System. The controller has six ports. Three of them are used during a normal install:

  1. Power port (far left)
  2. UF #1 flush ball valve port
  3. UF #2 flush ball valve port (two-stage systems)
UF Controller showing the row of six ports 1 2 3
1 Power Port 2 UF #1 Port 3 UF #2 Port
Figure 1. The Controller Ports
The three labeled ports are the ones you connect: power (1), UF #1 (2), and UF #2 (3). The unlabeled ports between them are reserved for a future pressure connection and for programming. Do not connect anything to those.
NOTICE

Connect the power supply to Port 1, the far-left port, and nowhere else. Ports 2 and 3, the two ports just to the right of the power port, have the same two-hole size and shape as the power port but are not power inputs. They are reserved for a future pressure connection.

Applying power to Port 2 or Port 3 will burn out the control board and permanently destroy the controller. Before plugging in, confirm the power harness is seated in the far-left port.

Power Supply Connection

WARNING

Electric shock. Mains voltage is present at the power adapter and cord. Contact can cause serious injury or death. Keep the adapter unplugged from the wall outlet until every connection in this Installation section is made.

Water and electricity. Keep the adapter, cord, and plug dry and off the floor. Do not immerse them. Mount the controller above any place water could spray or pool.

Take the included power supply with harness, and with the tab facing up as shown, insert the plug into the left-most port of the controller.

Flush Valve Connection

Take the flush ball valve with harness, and with the locking tab facing up as shown, insert the harness into the UF #1 Port.

Note: There are a total of six ports on the Controller. Port 1 (far left) is power. Ports 2 and 3 are reserved for a future pressure connection and share the same two-hole configuration as the power port. Port 4 is the programming port. The valve ports are last: UF #1 is the fifth port from the left and UF #2 is the sixth.

Note: If you have a two-stage UF System, connect the UF #2 Port (to the right of the #1 Port) to the second flush ball valve.
PROGRAMMING
For the User

Entering Programming Mode

WARNING

Electric shock. You are about to connect to mains power. Use a properly grounded outlet. Do not use a damaged cord or plug. Aquamor recommends a GFCI-protected outlet; test the GFCI per its instructions.

Cord routing. Route the cord away from hot surfaces and sharp edges. Do not pinch it under the bracket or in a cabinet door.

To enter programming mode:

  1. Plug the controller into a power outlet.
  2. Push the Right Arrow Button once.

The screen enters programming mode, as shown below.

Two thumbs pressing buttons in programming mode

Start Time

Set the start time of day for the UF to flush.

Note: The Aquamor UF Controller uses the 24-hour clock (24-hour time) only.

The first line to program is the Start Time: when the first flush takes place in a 24-hour period. Press the "Right Arrow Button" to align the cursor under the digit you want to change, then use the up/down arrows to change it. Below, the first flush is set for 3:00 am.

Flush Duration

Flush duration is how long the flush ball valve stays open during a flush. Press the Right Arrow Button again to move the cursor to Flush Duration. Duration is set in 5-second steps, from 5 to 60 seconds. The default is 15 seconds. On a 15-second flush at 60 PSI water pressure, the valve will flush 4 gallons of water.

  1. Push the Right Arrow Button to move to the RTC Time setting.
  2. Set the digit under the cursor with the up and down arrows.
  3. Push the Right Arrow Button to move to the next digit.

OPERATION
For the User

Manual Flush

You can start a manual flush any time, apart from the programmed flush times. Press and hold the left and right arrows together for 5 seconds. The screen switches from the time-of-day display to the programming screen. When the flush finishes, the screen returns to the time-of-day display on its own.

TROUBLESHOOTING

If the controller does not behave as expected, find the symptom below and try the action. When a row says to disconnect power and contact Customer Service, stop and do that before going further.

SymptomLikely CauseWhat to Do
Blank or dark screen No power. Adapter not seated in the power port, outlet is dead, or adapter has failed. Confirm the adapter is seated in Port 1 (far left). Try a known-good outlet. If the screen is still blank, disconnect power and contact Customer Service.
Will not flush or valve does not actuate Valve harness in the wrong port or unseated, flush interval or duration set wrong, or a valve fault. Confirm the valve harness is seated in the UF #1 Port. Check the flush interval and duration. Run a manual flush (see Operation). If it still does not flush, disconnect power and contact Customer Service.
Settings do not save or do not survive a power cycle Programming was not committed, or a clock or backup fault. Re-enter the settings and confirm each value on the screen. If the settings still reset after a power cycle, disconnect power and contact Customer Service.
Flushing too often or not at all Flush interval set wrong, or the start time and clock time do not match. Check the Flush Interval and confirm the RTC Time matches the current time of day (see Programming).
Water at a port, or moisture on the controller A leak or spray has reached the controller. Shock hazard. Stop. Disconnect power at the outlet. Do not touch the controller until it is dry. Contact Customer Service.
