Why doesn't my unit start?

You just plugged in the unit and it doesn't run and you know that you have plugged the unit in to a good outlet. This is what you do. Turn the humidistat knob all the way to ON. It should kick in then. Set the humidistat at the recommended 60% RH. The unit will power on and off automatically at the level which you preset.

WARNING All warnings and safety precautions should be adhered to.  Read and follow all instructions before operating your dehumidifier.

This symbol means warnings and safety precautions should be adhered to.
 

 This symbol means risk of electrical shock.

This symbol means risk of explosion.

1.  All warnings and safety precautions should be adhered to.

2.  Do not submerge the unit in water.

3.  Locate the unit on a flat, level, solid surface where the unit won't fall.  For example, a counter top or solid table that will not roll about.   Do not place the unit on a sofa or bed where the unit could be tipped over.  You may use a sturdy cart or stand only when using your dehumidifier for applications outside of your RV or boat.

4.  When the unit is in operation do not place the unit inside an enclosed cabinet or bookcase that will interfere with the airflow and the proper operation of the unit.

5.  The unit is designed to be portable, however, if you desire a more permanent location for your unit such as mounting on a wall or from the ceiling, you must ensure that the unit is mounted securely (won't fall) and remains level.  In addition the unit must be mounted in a way that it won't interfere with the airflow or safe and proper operation of the unit.  Consideration must also be given to the fact that there must be a suitable drain nearby.

6.  Do not store or use flammable chemicals, gases or liquids such as gasoline or diesel in the vicinity of this unit or any other electrical appliances.

7. Do not operate the dehumidifier or other electrical appliance in the bilge or engine room where gasoline, diesel or other combustible vapors may accumulate which could result in an explosion.

8. Do not store or use flammable chemicals, gases or liquids such as gasoline or diesel in rooms with an RH below 30% since in very dry rooms, static electricity may ignite combustible vapors which may result in an explosion.

9.  The unit runs on 115V AC power.  Be sure to plug the unit into a 3 prong grounded receptacle that has a properly rated and protected AC power source such as shore power or an inverter.

10.  Always turn off and disconnect the unit before moving, cleaning or servicing the unit.

11.  Repairs and servicing of the unit must be performed by a qualified boat or RV service technician.

Setup

Check the dehumidifier for damage caused during shipment.  If damaged do not operate.

Unpack the dehumidifier on a counter or flat surface.  Keep the original packaging material for a while in case you need to return the unit.

Attach the hose to the plastic drain pipe. The Unit ships with a six-foot length of vinyl hose.  You may cut the hose to a suitable length for your application.  Although it is not necessary, you may use a hose clamp (not included) to attach the hose to the drain pipe.  If you wish to replace the hose you may purchase clear vinyl hose with a 5/8” inner diameter at your local hardware or marine store. 

Note: If a leak develops from rotating the drain pipe: The grommet is notched on the inside of the drain pan (fig 3). The notch must remain horizontal or leaks may occur (fig 1). If you rotate the elbow barb to the opposite direction and a leak develops its probably because the grommet has rotated along with the elbow barb (fig 4). To stop the leak the grommet needs to be reset to where the notch on the grommet is horizontal (level) fig 1.

TIP: To prevent the grommet from turning hold down the grommet with one hand while turning the elbow barb with the other hand.

TIP: To prevent the grommet from turning hold down the grommet with one hand while turning the elbow barb with the other hand.
TIP: If leaking persists:
Use a dish drain tray/pan (like the kind used under a dish drain rack) under the DH-5 to catch undesirable leaks.

The unit uses gravity for water to flow out of the unit therefore always route the hose at a height level with the unit or better yet route the hose down below the units level and never up higher than the units level otherwise the water will not flow out and will back flow into the drain pan.  Do not allow any kinks in the hose that will block the flow of water through the hose.  Route the drain hose to a suitable drain such as galley sink or bilge.

Do not drink the water that collects in the drain pan.

Operation

Be sure to plug the unit into a 3 prong grounded receptacle that has a properly rated and protected AC power source such as shore power or an inverter.

The dehumidifier runs on normal AC only (115V) household or shore power.  Make sure it is connected to a grounded (3 prong) 115 volt receptacle.

 

Turn the rotary control knob (humidistat) to on.  Set the humidistat at the desired level suitable for your application.  The manufacturer recommends setting the level at 60% RH (relative humidity).  At settings lower than 50% woodwork may become dried out.  For different applications see the other usage table for the recommended RH setting.  The dehumidifier will cycle on and off as needed to hold the moisture level you preset.

Fig 1 Humidistat

Locating the Unit

Locate the unit in the Galley, berth, or head, or where the air is stagnant or where mold and mildew has formed in the past.  Direct the exhaust airflow towards areas where moisture is a problem - v berth or head.

For best results, close outside doors, hatchet, portholes, etc.  Set the dehumidifier to 60% RH.
For different applications see the other usage table for the recommended RH setting.

Store and operate the unit on a level upright position.  Normal roll of the boat or RV motion won’t affect it.  Rough handling or dropping the unit will cause it to malfunction.

 

Do not store or use flammable chemicals, gases or liquids such as gasoline or diesel in the vicinity of this unit or any other electrical appliances. Do not operate the dehumidifier or other electrical appliance in the bilge or engine room where gasoline, diesel or other combustible vapors may accumulate which could result in an explosion. Do not store or use flammable chemicals, gases or liquids such as gasoline or diesel in rooms with an RH below 30% since in very dry rooms, static electricity may ignite combustible vapors which may result in an explosion.

Marine Dehumidifier Usage

Protect your valuable investment and equipment by removing harmful levels of humidity.

Improve your personal comfort by removing that “caramel apple” sticky humidity from your environment.

Help prevent mold and mildew growth by removing the humidity necessary for them to thrive on.
Reduce condensation on cold surfaces and walls.

Store your equipment such as sails, PFDs, electronics, bedding, towels, in a low humidity environment you create.

Mold Prevention Program

DH-5-1 Program for the prevention of mold and mildew growth in your boat or RV

Here are a few good guidelines for a mold prevention program to use in conjunction with your DH-5-1 dehumidifier.

follow this link to Mold prevention program.
 

[Back to the top]

More effective for humidity control than air conditioning  (20% to 80% humidity level selection)

More economical than air conditioning (150 watts at 115 volts AC) especially in an unoccupied boat or RV

Effective in applications of 1000 sq feet or less (150 cu. Ft. of air per minute)

Effective in applications where continuous draining is necessary (no bucket to empty)

If you have employed the use of extensive fine wood flooring, paneling, trim, cabinets and furniture in your boat or RVs interior, you will want to keep your humidity levels between 50% RH and 60% Rh. At levels lower than 50% woodwork may become dried out.

[Back to the top]

Spray a small amount off SST cleaner on the cabinet and wipe off with a rag to keep the cabinet clean and shiny. 

Occasionally check the evaporator (water collection coil at the air intake, (knob end)) and the condenser. If it is contaminated with dust and dirt, have the dehumidifier cleaned by a boat or RV service man. A dusty or dirty evaporator coil or condenser reduces the units efficiency.

Clean and dry out the drain pan and hose occasionally, since a dirty, moist drain pan or hose is a breeding ground for mold, mildew and bacteria.

Inspect the hose for blockage caused by kinks, dirt or mold and mildew. Clean and straighten as necessary.

Always unplug the unit before cleaning or servicing the unit.  Empty the drain pan to avoid water spilling (soak up water with dry sponge, cloth or paper towel).

A qualified boat or RV service technician must perform service, repairs and other maintenance!
