American Aldes DHV-150H Manuale Utente

• 

Avoid discharging the air directly at people, or over 
the water in pool areas. 

• 

If used near a pool or spa, be certain there is NO 
chance the unit could fall into the water or be  
splashed and that it is plugged into a GROUND 
FAULT INTERRUPTER. 

•

 

DO NOT use the DHV-150H as a bench or table. 

•

 

A drain pan MUST be placed under the unit if 
installed above a living area or above an area 
where water leakage could cause damage. 

 
Place the DHV-150H on supports that raise the base of 
the unit above the top of the flanges on the drain pan 
beneath it. Raising the DHV-150H will help the unit drain 
with gravity flow. Do not place the DHV-150H directly on 
structural building members without vibration absorbers 
or unwanted noise may result. 
 
The DHV-150H may be suspended with steel hanger 
straps (plumbers tape) or a suitable alternative from 
structural members. Remember to place a drain pan 
under the unit if it is suspended above a finished area or 
above an area where water leakage could cause 
damage. 
 
The DHV-150H should be located near the existing air 
handling system to minimize the required ductwork for 
connecting the DHV-150H to the existing air handling 
system. The controls for the DHV-150H are remote from 
the unit and must be located in the space that is to be 
conditioned. The controls are low voltage (24 volt) and 
should be connected to the DHV-150H with low voltage 
thermostat cable. 
 
An external insulation kit is available for the DHV-150H. 
This will prevent the cabinet from sweating if the unit is 
installed in an unconditioned space. This kit will also 
increase the efficiency of the unit by eliminating 
unwanted heat transfer between the unit and the 
unconditioned space. See the optional parts list for 
information on the kit. 
 
If fresh air ventilation is desired, thought should be 
given to the location for the fresh air ducting. A 6” round 
insulated duct will have to be installed on the DHV-
150H and run to the outside of the structure to bring in 
fresh air. Use an 8” insulated round duct for lengths of 
more than 50 feet or if more than 100 CFM is needed. 
Consult local codes for necessary distances from 
exhaust ports when installing fresh air return. 
 

 

 
The DHV-150H plugs into a common grounded outlet 
on a 15 or 20 Amp circuit. It draws around 12 Amps 
under normal operating conditions. If used in a wet area 

(pool, spa room, or basement prone to flooding), a 
ground fault interrupter protected circuit is required. 
 
Install the remote control panel in a central area of the 
structure where it will sense the relative humidity of the 
structure accurately. Avoid installing the control panel 
near HVAC supply registers, exterior doors, a pool or 
spa. The installer must supply the wiring between the 
DHV-150H and the control panel. Be sure to safely 
route the control wiring to prevent damage during 
installation. Be careful not to cross the wires when 
connecting the DHV-150H and the remote control panel 
or damage to the transformer may result. 
 
The remote controls of the DHV-150H are powered by a 
low voltage circuit (24 Vac) and must NEVER contact 
or be connected to a high voltage circuit. The control 
wires leaving the DHV-150H and the remote control 
panels are numbered and color-coded to prevent 
confusion. Some of the control wires leaving the DHV-
150H may not be used with certain control panels and 
should be left safely disconnected with wire nuts taped 
onto the stripped ends. Be sure to consult the electrical 
schematic in this manual or inside the access panel of 
the DHV-150H before making the control connections. 
 

WARNING: DO NOT ALLOW THE YELLOW LEAD 
FROM THE DHV-150H TO CONTACT THE RED 
LEAD OR ORANGE LEAD FROM THE DHV-150H 
OR DAMAGE TO THE TRANSFORMER WILL 
RESULT. 

 

NOTE: RESET THE VENTILATION TIMER BEFORE 
ATTEMPTING TO PROGRAM AFTER INITIAL 
INSTALLATION. THE TIMER MAY NOT OPERATE 
CORRECTLY UNTIL IT IS RESET. 

 
If an extension cord is required, it must have a 
minimum of 12 gauge conductors if 25 feet long or less 
and 10 gauge conductors if greater than 25 feet long. 
 

 

 
Condensate drains by gravity via the clear hose 
extending from the unit. Route the hose to a suitable 
drain. 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. It will slide tightly inside the end of the drain 
hose. If more than one length of pipe is required, they 
can be joined with a short piece cut from the end of the 
drain hose.
