Page 3: Introduction - Cautions
Before any service or maintenance is performed make sure main power supply is disconnected and safety labeled (If Carnes unit is set up with a built-in circuit breaker, turn off circuit breaker and additionally turn off main power supply breaker). Failure to turn off main power supply could result in fire, electrical shock or both, resulting in damage to property, personal injury or death.

CONTROL CONNECTIONS The circuit board can provide either a Carnes legacy 18VDC or an industry standard 24VAC, as a supply for those humidistats which require it. The supply for both the control humidistat and high-limit humidistat are output on pin1 of J16 and J17 respectively.

The circuit board also closes a power contactor allowing EXTERNAL MONITORING current to flow to vertical electrodes sealed inside the Pins 1 and 2 connector J10, shown in Photo H, are provided for cylinder. Current flows between the electrodes using indicating operation of the humidifier at a remote location.

High water sensors can be cumulative The Control humidistat, which provides the Control Demand, is depending on the condition of the water. normally the humidistat in the room being humidified. It is either installed in the room itself or the return air duct. The High-Limit humidistat, which provides the Hi-Limit Demand, is a safe-guard humidistat installed in the supply duct roughly 10-15 feet past the distribution tube.
Page 19 This page adjusts the Maximum Output of the humidifier. The “SETTINGS” Maximum Output can be adjusted lower from the nominal output value of the unit (set at the factory). The unit cannot be set lower than 20% of the nominal value of the humidifier. The Maximum Output value, when changed, also changes the Max Setpoint value on the Setpoints page.

Page 26: Short Absorption Manifold
CARNES STEAM MANIFOLDS reduce the non-wetting distance when required because of space constraints in duct system. SHORT ABSORPTION MANIFOLD Carnes Steam Manifolds are designed to pro- vide dry steam with rapid absorption in the duct air stream. It achieves this by distributing steam evenly across the face of the duct.
Page 27 Additional dis- tance is required for installation upstream of high efficiency filters. Carnes humidifiers operate at .5 psi or less so there are limita- tion on the length between the humidifier cabinet and the steam manifold.
