Complete the coil chloride (salt) removal following these steps
• CHLOR*RID® is a concentrate to be used for both normal inland applications at a
100:1 mix ratio OR for severe coastal applications 50:1 mix ratio with potable
water, (2.56 ounces of CHLOR*RID® to 1 gallon of water). Using a pump up
sprayer, fill to the appropriate level with potable water and add the correct amount
of CHLOR*RID® salt remover leaving room for the pump plunger to be reinserted.
• Apply CHLOR*RID® to all external coil surfaces using a pressurized pump up
sprayer maintaining a good rate of pressure and at a medium size nozzle spray,
(not a solid stream and not a wide fan but somewhere in the middle). Work in
sections/panels ensuring that all areas are covered and kept wetted.
• Generously soak coils by spraying CHLOR*RID® directly on and into the fin pack
section. Let stand 5 to 10 minutes keeping the area wetted. Do not allow to dry
before rinsing.
• Using pressurized potable water, (< 100 psi), rinse the CHLOR*RID® and
dissolved chlorides/salts off of the coils continuing to always work in
sections/panels.
• Starting at the top of the coil, begin rinsing the coil form side to side until you reach
the bottom. Repeat as many times as is necessary to ensure all coil
sections/panels have been completed and are thoroughly rinsed.
• Reinstall all panels and tops that were removed.

• Check and tighten all field and factory electrical connections.

• Check and clean the drain pans and blow out the condensate drain line.
• If the drain is plugged, water will back up into the dehumidifier and flood the mechanical
room.
• Check and adjust the air flow per specifications.
• Dirty ducts, filters, and coils may have reduced the total air volume.
• Check the operating pressures of the refrigeration circuits.
• Check the current draw of each blower motor.
• Check the current draw of each compressor.
• Note that the bearings on fan motors are permanently lubricated and do not require regular
lubrication.
