WARNING

Always switch off the electricity supply to the unit before you remove the cover.

If you have a problem...

Service should only be performed by qualified personnel

Symptom

Cold water only –

neon light off.

Water too cold – neon light on

Cause

Electricity not on or one of the supplies has failed.

The water supply is connected to the outlet of the unit.

One or more of the heater module cut-outs has tripped.

Plumbing crossover.

The flow transducer is not working.

Water flow is too high.

One of the power supplies is not on.

The power supply voltage has dropped.

Temperature dial is turned too low.

The inlet water temperature has dropped.

What to do

Check electricity supply.

Reconnect the water supply to the inlet of the unit (marked blue).

Turn off the power, open the unit and reset by pushing the button(s) on the top of the heater module(s). Establish and fix the cause of the overheating.

Test by turning cold water supply off to heater, then open hot water faucet(s).

No pressurized water flow should be evident. If it is evident, then that plumbing crossover needs to be corrected for the heater to operate.

Turn off the power, open the unit and observe if the flow transducer “spins” when the water is turned on. If not, contact CEC toll free at 800-798-8161.

Adjust the water flow (see Graph 1 on Page 8).

Check the supply voltages to the heater and rectify if necessary.

This is likely an issue with the power supply. Compensate for this by increasing the temperature setting

(turn dial clockwise).

Turn the temperature control dial clockwise.

Turn temperature knob up or reduce the flow rate according to Graph 1 on Page 8.

Using the Powerstream Pro

WARNING

Do not use the unit if you think it may be frozen, as this could result in ser ious damage to the unit. Wait until you are sure that it has completely thawed out before you switch it on.

Check that the power is switched on at the circuit breaker panel.

Turn on the hot water faucet FULLY. The hot water temperature can be changed by adjusting the temperature dial on the bottom surface of the unit. (The dial adjusts the temperature typically between 95°F and 131°F. The factory sets the temperature dial at the lowest position.)

There are internal safety thermal cut-outs which will operate if the unit overheats. If a thermal cutout trips, then it must be reset by a qualified electrician.

If the unit has been used recently, run the water through for a few seconds to let the temperature settle down. You may initially get a short burst of very hot water from the unit.

If a second outlet connected to the unit is also turned on, the hot water will be shared between the two.

Installing the Powersteam Pro

WARNING IMPORTANT

Do not install the unit in a room where there is a chance of freezing.

Read entire instructions.

Check the pressure of the main water supply. To operate correctly, the unit needs the following running pressures : Minimum: 15 psi (1 Bar) Maximum: 150 psi (10 Bar)

Securing the unit to the wall

WARNING

The unit must only be installed in the orientation shown in Diagram 1, i.e., mounted in a vertical position with the water fittings located at the bottom of the unit. Under no circumstances should the unit be

mounted differently.

If being used in a public place, position the unit out of easy reach to discourage vandalism.

Mount the unit onto a flat section of wall, well away from any potential splashes of water or spray.

Position the unit upright with all plumbing and electrical connections at the bottom of the unit.

Mounting on the wall

Undo the retaining screws on the front cover and take the cover off the unit. Hold the back plate in position against the wall and mark the four mounting holes.

Drill the holes and secure the unit using the four wood screws supplied or an appropriate alternative method.

Plumbing the unit

WARNING

Do not install a non-return check valve within 10 feet of the inlet. Do not apply heat or solder to

connections or pipes if they are already directly connected to the unit.

Fitting the pipes

The unit should be connected directly to the main cold water supply and not to pre-heated water.

(The inlet water temperature must not be greater than 86°F.) The unit should be installed with shut off valves on both the inlet and outlet connections.

It is recommended that you use ¾ inch or ½ inch copper or high -pressure flex connections.

Use Teflon tape for sealing pipe threads. Do NOT use pipe dope.

Remember to keep the hot water pipe runs as short as possible.

After the unit has been plumbed, and before you wire it, flush it with water to remove any debris or loose particles. Failure to do so may make the unit inoperable.

Connecting the unit to the pipes

The inlet and outlet connections are clearly marked on the unit. They each have a ¾ inch NPT connector.

Install a ball valve in the cold water line. This valve can be used to turn off th e water supply to the unit if it needs servicing, or to reduce the water flow if it is too high.

DISCLAIMER

As a condition of installing this product in the Commonwealth of Massachusetts a pressure relief valve shall be installed on the cold water side, by a licensed plumber MGL 142 Section 19 Approval number:

P1-09-25

Wiring to the unit in the United States of America

WARNING

The unit must be installed by a qualified electrician, in accordance with the current version of the National

Electrical Code. The unit must be grounded.

4

The outlet water temperature can also vary if the maximum flow rate is exceeded (see Graph 1) or if the supply voltage changes.

Each heater module is protected by an electro-mechanical thermal cut-out. If the temperature of any of the heater modules gets too high, then the cut -out will trip and cut the power to that heater module. If the cut-out operates, it must be reset by a qualified service person. This cut -out will only trip in exceptional circumstances.

The AE115 unit is supplied from two independent voltage supplies and the AE125 unit from three independent voltage supplies. The unit may continue to work if one of these supplies is switched off or fails, but the temperature control will be poor. (In Canada the unit has just one voltage supply).

Depending on the region of the country, the temperature of the water supply can vary between 40°F in winter to 70°F in summer, with an average of 55°F.

IMPORTANT

Before leaving the site, the installer should demonstrate the unit to the user and give them this guide.

How the Powerstream Pro works

The Powerstream Pro heats water instantaneously as it flows through the heater modules.

The electronic control monitors the flow rate and the incoming water temperature and then switches on the required number of heater modules to reach the temperature set by the ad justment dial.

As the flow rate or the incoming water temperature changes, the electronics adjust the number of heater modules used so that the outlet temperature is maintained.

The outlet water temperature can change slightly as the flow rate changes du e to the steps in power as different heater modules are switched on and off.

As a condition of installing this product in the Commonwealth of Massachusetts a pressure relief valve shall be installed on the cold water side, by a licensed plumber MGL 142 Section 19 Approval number:

P1-09-25

Wiring to the unit in the United States of America

WARNING

The unit must be installed by a qualified electrician, in accordance with the current version of the National

Electrical Code. The unit must be grounded.

The outlet water temperature can also vary if the maximum flow rate is exceeded (see Graph 1) or if the supply voltage changes.

Each heater module is protected by an electro-mechanical thermal cut-out. If the temperature of any of the heater modules gets too high, then the cut -out will trip and cut the power to that heater module. If the cut-out operates, it must be reset by a qualified service person. This cut -out will only trip in exceptional circumstances.

The AE115 unit is supplied from two independent voltage supplies and the AE125 unit from three independent voltage supplies. The unit may continue to work if one of these supplies is switched off or fails, but the temperature control will be poor. (In Canada the unit has just one voltage supply).

Depending on the region of the country, the temperature of the water supply can vary between 40°F in winter to 70°F in summer, with an average of 55°F.

WARNING

Always switch off the electricity supply to the unit before you remove the cover.

If you have a problem...

Service should only be performed by qualified personnel

Symptom

Cold water only –

neon light off.

Water too cold – neon light on

Cause

Electricity not on or one of the supplies has failed.

The water supply is connected to the outlet of the unit.

One or more of the heater module cut-outs has tripped.

Plumbing crossover.

The flow transducer is not working.

Water flow is too high.

One of the power supplies is not on.

The power supply voltage has dropped.

Temperature dial is turned too low.

The inlet water temperature has dropped.

What to do

Check electricity supply.

Reconnect the water supply to the inlet of the unit (marked blue).

Turn off the power, open the unit and reset by pushing the button(s) on the top of the heater module(s). Establish and fix the cause of the overheating.

Test by turning cold water supply off to heater, then open hot water faucet(s).

No pressurized water flow should be evident. If it is evident, then that plumbing crossover needs to be corrected for the heater to operate.

Turn off the power, open the unit and observe if the flow transducer “spins” when the water is turned on. If not, contact CEC toll free at 800-798-8161.

Adjust the water flow (see Graph 1 on Page 8).

Check the supply voltages to the heater and rectify if necessary.

This is likely an issue with the power supply. Compensate for this by increasing the temperature setting

(turn dial clockwise).

Turn the temperature control dial clockwise.

Turn temperature knob up or reduce the flow rate according to Graph 1 on Page 8.

Using the Powerstream Pro

WARNING

Do not use the unit if you think it may be frozen, as this could result in ser ious damage to the unit. Wait until you are sure that it has completely thawed out before you switch it on.

Check that the power is switched on at the circuit breaker panel.

Turn on the hot water faucet FULLY. The hot water temperature can be changed by adjusting the temperature dial on the bottom surface of the unit. (The dial adjusts the temperature typically between 95°F and 131°F. The factory sets the temperature dial at the lowest position.)

There are internal safety thermal cut-outs which will operate if the unit overheats. If a thermal cutout trips, then it must be reset by a qualified electrician.

If the unit has been used recently, run the water through for a few seconds to let the temperature settle down. You may initially get a short burst of very hot water from the unit.

If a second outlet connected to the unit is also turned on, the hot water will be shared between the two.

Installing the Powersteam Pro

WARNING IMPORTANT

Do not install the unit in a room where there is a chance of freezing.

Read entire instructions.

Check the pressure of the main water supply. To operate correctly, the unit needs the following running pressures : Minimum: 15 psi (1 Bar) Maximum: 150 psi (10 Bar)
