5.6.2 Detailed Problems
Why is there water is carrying over into the air stream and/or the water appears to be foaming?
• Make sure the humidifier evaporative material has been completely flushed at commissioning, to remove
all manufacturing residues, including surfactants. Refer to the commissioning section of the manual.
• The humidifier matrix may be incorrectly fitted. Check the humidifier cassettes have been fitted correctly
by referring to the HE2 assembly guide.
• Check HE2 installation is level in both planes.
• The water distribution header or pipework is damaged or incorrectly fitted. Check all pipes and fittings for
damage. Check the water distribution header has been fitted correctly.
• The air velocity or flow might be uneven across the face area of the system. Fit a perforated plate before
the HE2 .
• The junction cover may be incorrectly fitted. Check the junction cover bracket is correctly fitted as shown.
• The air velocity across the face of the humidifier might be too high. Check the air velocity against the
specification for the unit. Note that the HE2 system has the following limits (see table):
No Separator Separator
3.5 m/s (11.5 ft/s) 4.5 m/s (15 ft/s)
Why is the HE2 unit on but not filling up with water?
This could be due to:
• The control panel is not switched on. Switch on and check set-point.
• The water supply has been isolated. Check for water supply.
• The unit is outside occupancy. Check occupancy settings and times on the HE2 controller; see “Step 9
Programming the controller’.
• No demand for humidity. Refer to controls section of the current manual and check the control parameters
are correct, see “Step 1 Programming the controller” in the commissioning section. Check the demand for
humidity or temperature (if cooling) is set for the desired condition.
Water is leaking from the evaporative module tank or AHU, what should I check for?
• Check that the HE2 is installed in a water proof section with drain pan.
• The tank level may be wrong. Check the tank is installed level in both planes.
• The HE2 system might be incorrectly fitted. Check the humidifier has been fitted correctly by referring to
the HE2 assembly guide.
• The tank might be damaged. Check the tank for damage or holes.
• The drain pipe-work connection is damaged or incorrectly fitted. Check the pipe-work for leaks.
• Check that the float valve shuts off the water supply when the water depth rises above the bottom edge of
the cross member (as shown ).
The module pump won't start, why?
• The control panel is not switched on. Switch on and check set-point.
• The evaporative module tank water level isn't high enough. Check water level float switch position.
• The unit is in a fault mode. Refer to basic problem 3)ii.
• The unit is not calling for humidity/no control signal. Check control signal.
• The unit is out of occupancy. Check occupancy times, refer to programming the controller in the 'commis-
sioning' section of the current manual.
Water sampling tests show contamination. What should I do?
• Check the drain pipe-work is not blocked and operation of the drain valve.
• This may be due to the AHU air, or supply water being contaminated. Refer to “ HE2 Routine Water
Sampling and Testing” and “Cleaning and Disinfection” section. This can be found in the “maintenance”
section.
• Review the maintenance and cleaning requirements.
• Check the intake of the AHU for a contaminated source of moisture such as an ornamental pond fountain
or cooling tower “drift’. Note: A build up of 'dust or dirt' on the air on side may indicate air filtration problems.
