Planning The Installation; Frequent Cycling; Water Or Steam Cleaning; Corrosive Chemicals - Honeywell WV4460E 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 7).
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.

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
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.
