Compressor Dehumidifier Operating Tips

Your solution for a dryer, healthier indoor climate

NWT: World leaders in the manufacture of high quality dehumidifiers for over 30 years
10 million Dehumidifiers and counting!

Preparation & setting up your dehumidifier

  • Place the dehumidifier in the worst moisture affected room
  • Close windows and doors to speed up the drying process
  • Open wardrobe doors, particularly if the wardrobes are musty and
    affected by moisture
  • Consider operating a ceiling fan on low or medium to speed up the drying process
  • For optimum drying, operate in room temperatures between 20˚C and 30˚C

Drain options:

  • Water tank option – remove and empty water tank each time it fills with water (recommended)
  • Continuous drainage hose option – allows you to bypass the dehumidifier’s water tank, which avoids the need to physically empty the water tank each time it fills

Methods of drying:

Initial drying

Commence by deep-down drying your home. This method will remove excess moisture levels in your furnishings, walls and ceiling therefore returning your room to its original dry condition.

To achieve deep down drying of each room, we recommend the following steps:

  • Set the dehumidifier’s humidistat control to the low levels of 30% – 40% for electronic models or turn the humidistat dial fully clockwise for the manual models. This will allow the dehumidifier’s drying process (compressor) to run continuously for best drying results.
  • The dehumidifier will stop automatically when the water tank is full
  • Empty the water tank and continue use
  • Continue this drying process for 1 – 3 days in each room. This period can vary depending on the dehumidifier’s capacity, severity of moisture, size of room & temperature. If you are unsure please contact your Ausclimate representative

Note 1: Reduced moisture collection in the water tank may be an indication that the dehumidifier has removed or nearly removed the excess moisture e.g. the dehumidifier’s water tank has filled once or twice, but it then takes several hours to collect a very small amount of water.

Note 2: The dehumidifier should be rested for 2-3 minutes before emptying the water tank. This will allow the moisture around the dehumidifier’s ‘cold coils’ to drain away before removing the water tank.  Any additional water may be removed from the dehumidifier by unplugging the rear drain and tilting the machine backwards.

Follow up or maintenance drying

Option 1

This will help prevent your room & furnishings from reverting to excessive moisture levels. The regularity of this drying will vary according to weather conditions & season – generally from a week or two, through to several months in dryer seasons.

To achieve this we recommend following the same steps as above (initial drying), however you will only need to run the dehumidifier approximately 8 – 12 hours at a time.

Note 3: larger models may dry more than one room at a time with this option

Option 2

Consider choosing constant ‘pre-set’ humidity levels within the room/home after the deep-down drying process. Reasons for doing so may include:

a) Comfort of lower humidity

b) Ongoing protection of property, collectables & other valuables such as stamps, books,
artwork, etc.

c) Freshen up after home/room closure for prolonged periods

To achieve maintainence of room humidity levels we recommend the following steps:

  • Set the dehumidifier’s humidistat to 50%-60% for electronic models or ‘normal’
    (1 o’clock position) for manual models. This setting is comfortable for most people
  • Some property, collectables & valuables may be suited to lower humidity levels
  • Empty the water tank manually, or alternatively use the continuous drain option

Note 4: The dehumidifier’s compressor will automatically stop when the room’s humidity level has been reduced to the selected setting. The compressor will restart again when the humidity rises above the selected level and will switch on and off as the humidity fluctuates.

The dehumidifier’s fan will continuously operate during this process for selected models (electronic models excluding Supreme All Season model).

Safety tips & reminders:

This Operating Tips document is intended as a guide only

  • Electrical appliances should not be left running unattended for extended periods
  • Don’t ‘over-dry’ by operating dehumidifier at ‘low humidity’ settings for
    extended periods
  • Don’t let children operate or play near the dehumidifier
  • Refer to the User’s Manual for other operation and safety warnings
  • Contact your Ausclimate representative for clarification or further information
    if unsure about the safe and efficient operation of your dehumidifier
