American Aldes DHV-150H specifications Electrical Requirements, Condensate Removal

∙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.

2.2 Electrical Requirements

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.

2.3 Condensate Removal

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.
