Planning The Installation; Corrosive Chemicals - Honeywell WV4262B Installation Instructions Manual

PLANNING THE
INSTALLATION
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death, or property
damage.
Follow these warnings exactly:
1. Plan the installation as outlined below.
2. Plan for frequent maintenance as described
in the Maintenance section (see page 8).
3. Review the following conditions that can
apply to your specific installation and take
the precautionary steps suggested.
Frequent Cycling
This control is designed for use on appliances that
typically cycle three to five times a day. In year-around
applications with cycling rates greater than 3,000
cycles annually, the control can wear out more quickly.
Perform a monthly checkout.

WV4262B POWERED DAMPER WATER HEATER CONTROLS
Water or Steam Cleaning
If a control gets wet, replace it. If the appliance is likely
to be cleaned with water or steam, protect (cover) the
control and wiring from water or steam flow. Mount
the control high enough above the bottom of the tank
so it does not get wet during normal cleaning
procedures.
High Humidity or Dripping Water
Dripping water can cause the control to fail. Never
install an appliance where water can drip on the
control. In addition, high ambient humidity can cause
the control to corrode and fail. If the appliance is in a
humid atmosphere, make sure air circulation around
the control is adequate to prevent condensation. Also,
regularly check out the system.

Corrosive Chemicals

Corrosive chemicals can attack the control, eventually
causing a failure. If chemicals are used for routine
cleaning, avoid contact with the control. Where
chemicals are suspended in air, as in some industrial
or agricultural applications, protect the control with an
enclosure.
Dust or Grease Accumulation
Heavy accumulations of dust or grease can cause the
control to malfunction. Where dust or grease can be a
problem, provide covers for the control to limit
contamination.
Heat
(121)
Excessively high temperatures can damage the
control. Make sure the maximum ambient
temperature at the control does not exceed the rating
of the control. If the appliance operates at very high
temperatures, use insulation, shielding, and air
circulation, as necessary to protect the control. Proper
insulation or shielding should be provided by the
appliance manufacturer. Verify proper air circulation is
maintained when the appliance is installed.
