Power water sprayer may be used in pressures
under 600 psi. Water will work best when blown
thru the coil from the non-air side when possible.
Spraying thru from the airside may imbed debris in
the coil that was only on the surface. It is
recommended to start with one of the first three
options before using water if the non-air side is not
accessible. The angle at which the water should be
directed at the coil should not be less than 75
degrees (
). The spray nozzle should
be kept between 1 inch and 3 inches (25 to 75
millimetres) from the coil surface.

1. Chemicals to aid in cleaning WILL VOID
WARRANTY and are NOT RECOMMENDED.
2. In some instances, it may take a
combination of two methods to result in a
clean coil. Such as, first wiping the coil to
clean the surface and then using a vacuum,
water or compressed air to clean down in
the fins. This will depend on the type of
debris that needs to be cleaned from the coil.
3. Do not contact the coil with any hard
vacuum nozzle, air nozzle, or any other tool.
This will damage the tubes of the coil.
