Use care to keep the hose as flat to the floor as possible, excessive humps will prevent proper drainage. If the DHV-150H is located too far from a drain for the attached hose to reach, inexpensive 1/2" PVC pipe can be used to extend it. It is commonly available in 10' lengths from building supply, plumbing or hardware stores. -
Page 3: Ducting
If fresh make-up air is desired see section 2.4C. The outlet of the DHV-150H is located on the end of the unit. A second 10” round collar is supplied with the unit. Cut and remove the safety grid, then bend the tabs on the collar inside the hole in the cabinet end. -

HVAC system. Connect an insulated duct from outside to the 6” collar of the DHV-150H if you wish to provide optional fresh make-up air. Crawl Space Installation: Install a separate return for the DHV-150H in a central area of the structure. -
Page 5: Quiet Installation
A length of 10 feet or more of acoustical flex ducting on the outlet of the DHV-150H will reduce air noise from the fan. A length of flexible ducting on all DHV-150H duct connections is recommended to reduce noise and... - Page 6 Figure 1: DHV-150H in a Basement With a Forced Air System Incorporating a Central Return Figure 2: DHV-150H in an Attic with a Forced Air System Incorporating a Central Return...

Page 7: Operation
The DHV-150H can be equipped with various accessories to enhance its operation. A remote control panel must be used with the DHV-150H. There are two remote control panels from which to choose. The humidity/fan control panel is used to control humidity and the fan. -

If the timer fails to operate or operates erratically, check that the control panel receives 24Vac from the DHV-150H. If 24Vac is present at the control panel, reset the timer by pressing the reset button at the bottom center of the timer face. The reset button is the small recessed button with an R beneath it located below the 1…7 and h buttons. -
Page 9: Maintenance
To access the air filter, remove the filter access panel from the end of the DHV-150H by unscrewing the two thumbscrews and sliding the panel to the left until it is free from underneath the side panel. The filter(s) should be readily visible and can be removed by pulling them straight out of the DHV-150H. -

maintain nearly 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. -

6. Turn on the fan switch; the fan should run. Turn off the fan switch. 7. Turn on the humidity control; the compressor and fan should run. 8. If these tests work, the problem is most likely in the field control wiring. 5.4 Refrigerant Charging If the refrigerant charge is lost due to service or a leak, a new charge must be accurately weighed in. -
