WATER SUPPLY
: Connect a 3/4-inch water supply pipe to the connection. Supply
pressure should be at least 20 PSI (1.4 bars).
Maximum water consumption at full throttle will be about 270 gal/hr (1,022 liters/hr) of
which about 85 percent is evaporated and the remainder is bled off to the drain. Average
water consumption will be much less than this, perhaps as little as 50 gal/hr when the unit
supplies humid air only to the Lint Slide Grid.
TIPS
A good rule of thumb to test if water supply is adequate is to time how long it takes to fill
a 5 gallon (19 liter) container. If the filling time is 1 minute, the water supply is
adequate. If the filling time is 2 minutes, the supply is very marginal.
Some users have installed water softeners to minimize scale deposits in the Humidaire
Unit. Make sure the softener cannot recharge while the Humidaire Unit is running. If it
does, the salt it puts in the water will cause corrosion damage far more expensive than
scale accumulation. We can supply our Part No. 14000
Powdered Acid Descaler
in 50-
pound pails for scale removal. Please see the
POWDERED ACID DESCALER
section in
this manual for details on this.
Heavy concentrates of certain minerals in the water can cause scale deposits to quickly
form. The pH (or acidity) of the water also determines the severity of scaling. Consult the
factory if in doubt on the quality of the water. A water sample can be analyzed allowing a
good prediction of how much scaling will occur and means of controlling it.
WATER DRAINAGE FACILITY:
The Humidaire Unit drains water through a 2-inch
pipe located behind the water tank. Drainage is absolutely necessary for proper operation
of the unit because the water evaporated by the unit is distilled water. All minerals are
left behind in the machine. A small amount of water is purged automatically while the
water pump is operating. The amount of water purged will vary based on operating
conditions of the unit and the quality of the water. As a general rule, the drainage pit
should be capable of accepting about 1000 gallons (3785 liters) per day.
TIPS
The gin’s septic system is not a good choice for the drainage water to run into. The septic
system will quickly overflow from the purge water.
