12 HF Humidifier
Owner's Instructions for Electronically controlled FLOW-THRU Humidifier
Operating and Maintenance Tips - Warranty.
1. Principle of operation
•
This humidifier uses a vertical evaporator pad, wetted by a pulsed water flow. Warm air is by-passed from
the warm air plenum and forced through the evaporator pad. Humid air is drawn back into the return duct.
•
The pad is enclosed in a plastic frame with a marking that clearly indicates the bottom. It is designed to
retain water before it is evaporated. Any excess water is sent to the drain.
•
All flow-through humidifiers improve performance and evaporative capacities if they are used
with constant blower operation. However, this unique pulse action model optimizes performance and
reduces water consumption by up to 80%.
•
When the humidity level drops below the set point on the humidistat and the furnace is running, the patented
electronic controller activates the unit. Small amounts of fresh water are then added intermittently (approximately
2 seconds on and 30 seconds off) during the heat cycle and dispersed onto the media pad. The humidified air is
then circulated throughout your entire home. This is one of the main features of this model and it saves up to 80%
of water consumption compared to other flow through humidifiers which continually dispense water onto the
evaporator pad. It is normal to have some water flowing in the drain tube. This flushing–away method removes
the dissolved minerals left on the evaporator pad and carried away to a floor drain before they settle and dry-up on
the pad.
2. Adjusting the humidity level in your home
•
A relative humidity environment of 40% is recommended. Please refer to the table on the humidistat front
plate to help determine the proper level.

•
At the beginning of the heating season it might take some time (a few days) to build up the humidity to
the comfortable level you want. Depending on the original dryness of the house, carpets, furniture and
wood will absorb moisture before feeling a difference.
•
If your house remains unoccupied during the winter season, adjust the humidistat to a lower setpoint in
order to prevent condensation.

3. A few tips
•
Do not use the supply valve (installed on the supply line) to regulate the water flow. This type of valve is
designed to be completely opened or closed.
•
Do not allow the drain tube to fill with water in bends, elbows or kinks. Water could accumulate inside the
drain tube leading to deposit build-up and/or result in back pressure preventing the water from draining
properly and cause an overflow.
4. Annual Maintenance
To replace the evaporator pad :
1- Unplug the transformer from the wall power supply.
2- Open the humidifier by removing the plastic screw on the side of the cover.
3- Unlock the evaporator pad by turning the little plastic retainer at the top of the pad.
4- Remove the old pad and replace it by a new one while checking the printed marking that clearly indicates
the bottom of the pad.
5- Lock the new pad in place.
6- Put the cover back and secure it with the plastic screw.
Note : Depending on the quality of water, it is recommended to replace the evaporator pad once per
heating season.
5. Summer season
•
If the system is used in air conditioning during the summer, reduce the air volume going through the
humidifier by closing the air damper located on the side of the humidifier. The control button shows
the actual position of the damper.
•
It is recommended to simply shut off the humidifier system :
1- Close the water supply valve.
2- Turn the humidistat knob to the "OFF" position.
3- Unplug the transformer.
