INSTALLATION/OPERATION

COMFORTMINDER

INSTRUCTIONS

INTRODUCTION:

Please read these instructions carefully before installing your COMFORTMINDER indicator. We have prepared

them carefully, knowing that some owners will use this instrument in a variety of areas for a variety of purposes –

greenhouse control, central air conditioning and heat monitoring, furniture protection, general comfort conditions

etc.

INITIAL ACTIVATION (HUMIDITY):

Before installation, place your indicator with its face down on a soft surface so as not to scratch the finish. Locate

a cloth, such as a dish towel or face cloth, wet it and wring it out so it is not dripping wet and lay it over the back

of the indicator for at least one half hour. Do not be concerned with the relative humidity reading at the end of

this time. Wipe any residual moisture off the back of the indicator when removing the cloth.

This procedure should only have to be done once, unless the COMFORTMINDER is to be used in areas of

persistently low humidities – that is, long periods where humidity is less than 40-45% RH. Once this activation

procedure is completed it may be several hours before COMFORTMINDER settles out to actual room conditions.

We include this initial “activation process” in our instructions because we often do not know where your

instrument has been and for how long, prior to your purchase. This procedure is for the humidity portion of

COMFORTMINDER only, and will not affect the temperature element or damage it.

INSTALLATION:

Your COMFORTMINDER indicator is easy to install. It is the actual location of the indicator that should take

some consideration. Simply put, the humidity sensing element of COMFORTMINDER is an absorption rather

than an evaporative device. Therefore actual air circulation is not vital to accuracy, but it will enhance response

rate.

The temperature element is a durable high quality Bi-metallic spring which is thermally coupled to the instrument

housing to attain as closely as possible, the average temperature in the area being monitored. Keeping this

information in mind, try to locate the indicator on a wall that will demonstrate, as closely as possible, the average

temperature and humidity in the area that is to be monitored – not on a cold outside wall or a wall with a heating

pipe or vent behind it or under it.

COMFORTMINDER can be mounted outdoors if it does not come in direct contact with moisture – spray, rain,

etc. Nor should it be used in direct sunlight, which could cause erroneous temperature readings. Place indicator

on the wall you have chosen and using the supplied brass screws, fasten to surface but do not snug down tightly.

Your indicator is designed to be spaced slightly off the wall. This space is controlled by the three spacers

mounted on the back of the indicator. These spacers, not the lip of the indicator, will make contact with the wall.

Once mounted, this space will hardly be noticeable.

stated earlier, it is to be used in areas of persistent low relative humidities. If COMFORTMINDER is subjected to such conditions, periodically follow initial activation instructions. This procedure does not apply to nor will it affect the temperature portion of COMFORTMINDER. * COMFORTMINDER is measuring the relative humidity and temperature at the location of the indicator, not at the local weather forecasting station.

to inside a building. Because relative humidity is dependent on temperature, the relative humidity will vary in a small area even though the specific humidity is not varying. A few examples will help illustrate this point. In a building, we measure the temperature and relative humidity in one location to be 75 degrees F and 50% RH, respectively. Referring to the psychrometric charts, we locate 75 on the bottom scale. We then follow the line vertically up to the intersection with the 50% RH curve.

Because of the high cost of the other two types of instruments, we will consider only the sling psychrometer. If you buy an official US Weather Bureau sling psychrometer, it will contain the proper operating instructions and tables for high accuracy usage. If the unit you obtain does not contain tables for various pressures, then you should obtain the official pamphlet from the Superintendent of Documents at the US Government Printing Office.

IMPORTANT ADDITIONAL INFORMATION Components: Along with the indicator, the following components are included with this instrument: Brass Case: Your brass case is solid brass A70-30 Holloware quality, with a durable lacquer finish. It is in fact a piece of jewelry and should be treated as such. It should be cleaned at least once a week to keep airborne pollutants (dust, etc…) and any moisture from collecting on the case thereby attacking the lacquer.
