| Troubleshooting Model
AE115/AE125 |
 COLD
WATER ONLY - NEON LIGHT OFF |
| 1. |
ELECTRICITY NOT ON OR ONE OF THE SUPPLIES HAS FAILED
Check electricity supply.
|
| 2. |
THE WATER SUPPLY IS CONNECTED TO THE OUTLET OF THE UNIT
Reconnect the water supply to the inlet of the unit (marked blue). |
| 3. |
ONE MORE OF THE HEATER MODULE CUT-OUTS HAS TRIPPED
Turn off the power, open the unit and reset by pushing the button(s) on the
top of the heat module(s). Establish and fix the cause of the overheating. |
| 4. |
PLUMBING CROSSOVER
Test by turning cold water supply off to heater, then open hot water
faucet(s). No pressurized water should be evident, then that plumbing
crossover needs to be corrected for the heater to operate. |
| 5. |
THE FLOW TRANSDUCER IS NOT WORKING
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
866-330-2729. |
|
WATER TOO COLD - NEON LIGHT ON |
| 1. |
WATER FLOW TOO HIGH
Adjust the water flow (see
Graph 1 on Page 8 of the manual).
|
| 2. |
ONE OF THE POWER SUPPLIES IS NOT ON
Check the supply voltages to the heater and rectify if necessary. |
| 3. |
THE POWER SUPPLY VOLTAGE HAS DROPPED
This is likely an issue with the power supply. Compensate for this by
increasing the temperature setting (turn dial clockwise). |
| 4. |
TEMPERATURE DIAL IS TURNED TOO LOW
Turn the temperature control dial clockwise. |
| 5. |
THE INLET WATER TEMPERATURE HAS DROPPED
Turn temperature knob up or refer to Graph 1 on page 8
of the manual. |
|
WATER FLOW TOO LOW |
| 1. |
THERE ARE RESTRICTIONS IN THE PLUMBING
Check the plumbing. Use only Teflon tape for sealing pipe joints. Inspect
and clean inlet filter screen at heater.
|
| 2. |
WATER SUPPLY PRESSURE TOO LOW
Check that all inlet shut-off valves are fully open. |
| 3. |
OUTLET SHUT-OFF VALVES ARE SET TOO LOW
Adjust outlet shut-off valves as described below:
- Open fully both inlet and outlet shut-off
valves at the heater, then:
- Turn on fully the highest flowing hot water
faucet (e.g., bathtub) closest to the outlet connection.
- Adjust the outlet shut-off valve until the
water flow rate form the hot faucet corresponds to the valve given on
Graph 1 on Page 8
of the manual.
|
|
WATER TEMPERATURE FLUCTUATES |
| 1. |
FLUCTUATING WATER PRESSURE OR CHANGING FLOW RATE
Avoid several hot water outlets being used at the same time as this causes
the temperature to fluctuate. |
