HUMIDIFIRST
Maintenance (continued)
End of humidifying season shutdown
The humidifier Master Panel should be powered off when the humidification system will
not be required for long periods of time. This will stop heat gain from the transformer.
This will also reduce ware on the electrical components that may occur during summer
storms. Shut off the power from the Building electric panel that feeds the Humidifirst
Master Panel or unplug the individual humidifier control/power panels. Also, empty the
water from the humidifier basin and wipe dry.
Humidistat
The humidistat is calibrated and tested before it is shipped. If you feel the humidistat is
out of calibration you can field adjust it but by only a small amount. If it is considerably
out of calibration, a new one may be required. Wipe any dust or dirt from the sensing
element to help to achieve proper readings.
When field calibration is called for, attempt to calibrate it in an environment that is
close to the desired set point of the space being humidified. Calibration should only
be done with a sling psychrometer.
To calibrate, set the humidifier humidistat indicator to read the same as the independent
measuring device. Remove the humidistat cover. Locate the adjustment screw at the top
of the humidistat and turn it until you hear a soft click. The humidistat is now calibrated.
Warranty
The warranty for the humidifier module and the Master Panel is for one year from the
date of start-up or 18 months from shipment, whichever comes first. Please find and
complete the “HUMIDIFIRST MIST PAC START-UP FORM”. There will be no
warranty of the equipment without the form being completed and returned to Humidifirst.
This warranty does not include labor. The warranty is for parts only. Spare parts are
under warranty for 60 days from the date of shipment. Humidifier modules controlled by
non-Humidifirst control boxes carry no warranty.
