2 Operation

2.1 Transporting the Ultimate 340

The Ultimate 340 must always be upright when transported by vehicle. It may be tipped on to its handle and back for loading and moving by hand.

2.2 Location

Note the following precautions when locating the Ultimate

340:

• It is designed to be used INDOORS ONLY.

• If used in a wet area, plug it into a GROUND FAULT

INTERRUPTER .

• DO NOT use the Ultimate 340 as a bench or table.

• It must always be used in the upright position.

• The air inlet on top & the side outlet must be at least

1 foot from walls and other obstructions to air flow.

www.jondon.com

2.3 Electrical Requirements

The Ultimate 340 plugs into a common grounded outlet on a

15 Amp circuit. It draws 10 Amps at 80°F, 60% RH. If used in a wet area, a ground fault interrupter (GFI) is required.

If an extension cord is required, it must have a minimum of

14 gauge conductors if 25 feet long or less and 12 gauge conductors if greater than 25 feet long.

The total and job hours measured are stored when the unit is unplugged. The previous total will be displayed the next time the unit is turned on. The job hours can be reset by pressing and holding the HOURS button for 5 seconds when the unit is operating.

2.4 Condensate Removal

The Ultimate 340 is equipped with an internal condensate pump to remove the water that is condensed during dehumidification. This allows the condensate to be pumped

30’ with the attached hose. If the condensate must be pumped more than 20 feet above the unit, a second pump must be added to relay the condensate. If the pump fails and the unit must be used before it can be replaced, the condensate can be drained by gravity (see Sec. 4.9).

2.9 Humidistat

Adjust the humidistat to the desired conditioned humidity.

The humidistat has a range of 20% to 70% RH. “ON” will operate the unit continuously regardless of humidity.

2.10 HOURS Button

Press the HOURS button when the dehumidifier cannot be plugged in and the hour meter needs to be read. The digital hour meter will display the last saved cumulative time for ten seconds.

2.5 Ducting

A detachable rectangular exhaust collar is supplied that will allow 10” round lay-flat duct to be attached to the Ultimate

340 outlet. Lay-flat plastic ducting is available from Jon-Don.

To attach ducting to a collar, put the plastic duct end through the collar center and roll the duct end outward so that it overlaps the outside of the collar. The duct and collar may then be quickly attached to the Ultimate 340 by snapping the collar over the four screws at the blower outlet.

2.11 DEFROST Light

The DEFROST light turns on when the unit is in defrost cycle and indicates when the compressor is off.

DRYING TIP: Air’s ability to absorb moisture from wet surroundings and the Ultimate 340’s ability to remove moisture from that air is greatly improved at higher temperatures. We recommend that the area to be dried be heated to over 70°F if possible. Less drying time will be required and efficiency will improve.

2.6 Power Button

Press the POWER button to turn the dehumidifier on or off.

When starting the dehumidifier the display will show the accumulated hours. Press the POWER button again to turn the dehumidifier off. The display will also power off.

2.7 Pump Purge Button

During normal operation the pump automatically cycles every four minutes. Press the PURGE button to remove condensate manually from the reservoir. There are several ways to manually remove water from the reservoir:

1. Press the PURGE button once and the pump will run for

20 seconds

2. Press and hold the PURGE button and the pump will run for up to 30 seconds

3. Press the PURGE button while the dehumidifier is powered off and the pump will run for 30 seconds.

Always manually purge the water reservoir before transport or storage. Turn off the power and allow the plugged in dehumidifier to rest 15 minutes before the final purge.

2.8 Hour Meter

The digital hour meter displays the cumulative and job time the dehumidifier has been turned on to the tenth of an hour.

Toll-Free 1-800-556-6366

2.12 Low Pressure Control

If the low side refrigerant pressure drops to 35 PSIG, the low pressure control opens and shuts off the compressor and blower. It is an automatically reset control. Its primary function is to prevent damage to the compressor if a leak develops in the refrigeration system. It may also open if stored where it is below 40°F and then started. Under these conditions, the unit will restart within several minutes; it may cycle several times until the unit warms up.

3 Maintenance

3.1 Air Filter

The Ultimate 340 is equipped with a pleated fabric air filter that must be checked regularly. The standard filter is a MERV-

11 high efficiency filter. Operating the unit with a dirty filter will reduce the dehumidifier’s capacity and efficiency and may cause the compressor to cycle off and on unnecessarily on the defrost control.

The filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be ordered from Jon-Don; call 1-800-556-6366 or at jondon.

com. DO NOT operate the unit without the filter or with a less effective filter as the heat exchange coils inside the unit could become clogged and require disassembly to clean.

www.jondon.com

3.2 Storage

There are two issues to consider when the Ultimate 340 is stored between uses and both pertain to the water trapped in the unit: damage caused by freezing or biological growth.

The effect of the trapped water can be greatly reduced if precautions are taken to remove as much as possible before storage.

1. Use the pump purge switch (see Sec. 2.7 & Fig. 4) to reduce the water level in the reservoir.

2. Stretch the hose flat to drain it completely. Raise one end above your head and spool to drain water out of the other end.

If the unit will not be exposed to freezing temperatures, an alternative to reduce biological growth is to flush the unit with a bio-fungicide that is approved for use with copper, aluminum and polyethylene. To flush:

1. Run the hose to a drain.

2. Plug in the unit but do not turn it on.

3. Remove the air filter. Slowly pour a quart of the chemical through the heat exchanger

4. Hold in the pump purge switch to reduce the water level in the reservoir.

5. Flush with water.

4 Service

CAUTION: Servicing the Ultimate 340 with its high pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit.

4.1 Warranty

A warranty certificate has been enclosed with this unit; read it before any repair is initiated. If a warranty repair is required, call Jon-Don at 1-800-556-6366 for warranty claim authorization and technical assistance.

4.2 Technical Description

The Ultimate 340 uses a refrigeration system similar to an air conditioner’s to remove heat and moisture from incoming air, and to add heat to the air that is discharged (see Fig. 2).

Figure 2: Refrigeration system

Hot, high pressure refrigerant gas is routed from the compressor to the condenser coil (see Figure 2). The refrigerant is cooled and condensed by giving up its heat to the air that is about to be discharged from the unit. The refrigerant liquid then passes through a filter/drier and capillary tubing which cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.

The evaporator operates in a flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain constant pressure and temperature across the entire coil, from inlet to outlet.

The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature to repeat the process.

4.3 Troubleshooting

No dehumidification, neither hour meter display nor compressor run and POWER button does not turn ON.

1. Unit unplugged or no power to outlet

2. Defective control board

3. Loose connection in internal wiring
