TRANSFORMER -
•
Hazardous Voltage Can Cause Personal Injury Or Equipment Damage.
•
Disconnect Power Supply Before Installing or Servicing.
•
On Multispeed Blower Applications, Do Not Wire The High Voltage Side Of The Transformer To The Same Power
Source That Services The Furnace Blower Or The Transformer May Burn Out Prematurely.
•
Do Not Attempt to Install the transformer unless you are an HVAC professional.
The transformer supplied with the unit is different then indicated in the supplied Installation/operating instructions. You have
been supplied with a Class 2 120Volt/24 VAC hard wire transformer. It is designed to be connected to the furnace through
the furnace accessory terminals, the furnace heating relay, or interlocked with the furnace blower. Install the transformer on
the outside of a grounded metal junction box using only a 7/8" knockout hole. Secure the transformer in place using the
locking nut on the transformer mounting sleeve.
HUMIDISENSE HUMIDIFIER CYCLING CONTROL
In the supplied installation/operating instructions reference is made to the electronic "Humidisense" humidifier cycling control,
and indicating LED's. Because models AK5000, AK5500, & AK7000 are contractor installed units, with the transformer
interlocked with the furnace's heating cycles the electronic controls and accompanying LED's are not required or installed on
the units. Your furnace humidifier will automatically cycle ON & OFF when your furnace cycles, no adjustments are required.
ELECTRONIC HUMIDISTAT CONTROL MANUAL AND AUTOMATIC OPERATION -
In the supplied Model 7000 installation/operating instructions & maintenance/warranty booklets reference is made to the
electronic humidistat control with manual and automatic operation. This control is not supplied with the contractor model
AK7000, in its place your unit has been provided with a standard mechanical humidistat design for either duct mount or wall
mount installation. Refer to the provided humidistat installation sheet for installation instructions.
ELECTRICAL WIRING –
Once the wiring is complete you should have all the components wired in series (a continuous loop) as shown in figure 1
below. To make the connection to the humidifier's solenoid valve use ¼" insulated male terminals or cut the ¼" female
terminals present on the solenoid valves wire then strip the wire ends – connect to the low voltage wire using approved
electrical wire nuts.
