Install the Plastic Liner and Wire Floor
Slide clips over
wire floor & underplastic liner
Unpack the incubator from the box and set
aside the power-supply, thermometer and
wire floor. Remove the top half from the
bottom. Attach Wire Floor to Plastic Liner
with Owl Clips then place floor and liner in
Hova-Bator Bottom. Arrange the plastic
floor as shown using the water troughs and
turner power cord notch as reference. Fill
Center trough (highlighted) with warm water.
Surface area, not depth, effects humidity; refill
trough as necessary to prevent it from drying
out. Place the top over the bottom.
Caution: The thermometer may not be as accurate as the thermostat and should
not be trusted on the first couple of hatches.
Plug the thin power cord into the
receptacle located in the incubator’s
top. Plug the cord set for the power
supply into the appropriate wall socket.
The fan should then run and the small
red light on the thermostat box should
be lit. Allow the incubator to warm up
for one hour. When the light begins
blinking regularly, the incubator is
nearing its set point. The thermometer
supplied maybe used to check the room
temperature and to indicate when
the incubator is nearing its operating
Warm eggs to room temperature (70Â°F. to
75Â°F.) and place them on wire floor. Let them
lay in a natural manner, which is on their sides
with the small end slightly down.
Read temperature with the thermometer
resting on top of the eggs or turner. Do not
put thermometer on wire floor as reading will
not be accurate.
Turn eggs 2 to 3 times a day. With a pencil, mark an X on one side and an O on the opposite side of
the egg. Turn all eggs so that XÂ’s appear face up. Next turning period turn all OÂ’s face up. Alternate this
routine each turning until 3 days before eggs are due to hatch.

The turner motor uses metal gears for additional strength when turning
heavy loads. These gears can emit noise during normal operation.
Three days before eggs are to hatch remove eggs from turner, lay them
on their side on wire floor in their natural unsupported position. Add water according to
instructions. Do not attemp to hatch eggs while turner is in the incubator as the slow turning
motor could crush the chicks.When turner is removed for hatching, maintain temperature by
placing thermometer on top of eggs.
The tuner operates very slowly. You should not expect to see movement upon installation.
Proper operation is detected my noting rack angle after 20 minutes.
NOTE: It is recommended that you
operate the incubator with a small
quantity of inexpensive eggs to be
assured of your operating procedure and
the performance of the incubator, before
attempting to hatch large quantities of
eggs or expensive eggs. Keep Reptile
eggs protected from moving air. (See
Warranty on Page 4).
Hovabator Manual Egg Incubator Model 1588 TEMPERATURE
An Incubator is designed to bring normal room temperature to the desired temperature. Room temperture of 60°F. or below will reduce the temperature
in the incubator. Room temperature change of 10°F. or more will change temperature in incubator & is more pronounced below a temperature of 70°F. The
location of the machine is important to successful operation. A room temperature from 70° to 80°F. is ideal, and fresh air without drafts is necessary. Be sure
no direct sunlight strikes the incubator and that it sets level. A consistant room temperature within a few degrees is best.
This incubator is pre-set for the proper incubating temperature for bird eggs requiring
a temperature of about 100o F. (37.5oC) (This is most of the known species.) No
temperature adjustment will be required. Because eggs, incubator and water are cold,
the incubator maybe slow to heat at first (up to 24 hours to reach 100oF) but will not
over heat and damage the eggs. Should the indicator light fail to cycle on and of_f after
set temperature is reached, re-toggle the rocker switch that sets the temperature as it
may have come unlocked. If after completing one or two hatches you feel it necessary
to slightly change the temperature, follow the instructions on the last page or call GQF
for technical assistance. Keep in mind that thermometers can be off or change over time
and should not be relied upon initially. The quality of hatch may be the best indicator as
to the temperature setting after considering other factors that can af_fect the hatch.
Notice: The 1588Â’s preset thermostat normally has accuracy greater than the thermometer supplied. If the thermometer appears to be off the desired setting
at anytime, it is recommended that the thermostatÂ’s presetting be used on the f_irst setting of eggs. Only if the eggs do not hatch well on the correct day
should the thermostat be adjusted (refer to Poor Hatch section on last page). It is suggested that a small number of inexpensive eggs be used during
the first setting to establish the operatorÂ’s procedure and the incubators desired operation.
THERMOSTAT SWITCHES Hovabator Manual Egg Incubator Model 1588
Add water every few days to the center trough only. Usually twice a week is sufficient. The amount of
moisture in the incubator is determined by the surface area of water exposed to the air. Under high
humidity conditions and for some species of birds, less humidity is required. (The humidity in the
incubator can be reduced by covering part of the water trough with aluminum foil and securing it
with tape) Whenever there are doubts about the level of humidity in the incubator, less is usually better
than more, except for the last two days. 2 to 3 days before the hatch, stop turning the eggs, and fill
both the center and the outer troughs with water.
PIace top on the incubator and do not remove until hatch is complete*. Remove dry chicks as soon as
possible to a brooder that has food and water and temperatures of about 95oF to 100oF. Chicks can survive
up to 48 hours after hatch without food or water, but feed and water them as soon as possible to avoid
stress. Some cases may require moving chicks to brooder to dry.
* After hatch pull red vent plugs to help dry chicks if necessary.
HATCHING Hovabator Manual Egg Incubator Model 1588
The purpose of supplying moisture in and
incubator is to prevent excessive drying
of the natural moisture from within the
eggs. The correct amount of humidity
can be determined by the size of the
air sack when candled, or by weighing
the egg to gauge percent of weight
loss. Both methods require knowledge
and experience that f_irst time operators
usually do not have. The Hova-Bator is
designed for simplicity in this matter, and
works well for most species.
A red vent plug is located on the top of the
incubator. This should be removed when the
incubator is used at altitudes greater than 6000
feet above sea level. The plug may also be
removed during or after the hatch if water drops
appear on the window due to high humidity. This
will help to dry the chicks and the incubator. If
removing the plug does not reduce the humidity
enough, it may be necessary to prop up the
top slightly, to facilitate drying. If so, be sure
to maintain proper temperature. Alternately,
the top may be removed quickly, and moisture
wiped from the windows to aid drying. Replace
the plug after chicks are removed.
Chicks may be removed 24 hours after they start to hatch.
Extremely wet chicks should be left in incubator to dry. If
they don’t dry in eight or more hours, remove them to a
brooder or heat lamp, with temperatures of 95oF to 100oF
Plan to remove chicks once a day, as every time incubator
is opened, warm moist air escapes. Avoid chilling of wet
chicks. Some chicks may be late in hatching, so you can
leave remaining unhatched eggs up to 2 days longer.
Clean your incubator after the hatch with soap and water
only. The plastic liner for the Hova-Bator bottom can be
cleaned using detergents or disinfectants.
When chicks are removed
from the incubator they must
have a place that is warm and
dry. A brooder should have
one section that is heated,
with a temperature of 100
degrees (for the f_irst week)
and an unheated section for exercise. Food and water should be
partially in heated area. Temperature should be reduced 5 degrees
each week until it is down to 70 degrees. Some types of chicks need
a temperature around 70 degrees until they are nearly grown.
The incubator top is not satisfactory as a brooder, as there is not
sufficient heat and the chicks may peck it to pieces. Feed and
water chicks at once. Check with a local feed dealer for the proper
feed for type of chicks you have hatched.

Hovabator Manual Egg Incubator Model 1588
There are many factors involved with the hatching process and any one can hamper or stop chick development. Old eggs, infertile eggs, damaged
or dirty eggs, poor flock health, and eggs not properly turned during incubation are some of the factors. Some chicks may only partially emerge
from the shell. These chicks after time may be assisted out of the shell but due to their weak condition often do not survive. It is not unusual in a
large batch of eggs to have a few of these even with good hatches.
Check the unhatched eggs. Take note of the exact number of days it took to hatch any eggs or note the number of days for any eggs to pip the
shell. Check unhatched eggs for chick development and note the number of these eggs in the batch. If all or most of the eggs have no development
(clear inside) then the microscopic embryo had died before or at time of incubation or the egg was never fertile. If 70% to 100% of the developed
eggs hatched then there is little adjustment that can be done with humidity or temperature to improve this. If many of the unhatched eggs
are developed or partially developed into chicks and if eggs were of good quality and properly handled then perhaps adjustments in temperature
or humidity may be required.
If eggs hatched on time, then begin any adjustments with the humidity first. Review the section under MOISTURE for adjustments. Make only
one adjustment and then test it on a setting of eggs before making any other adjustments.
If eggs have been determined to hatch late or pip late (one day or more), first check for too much humidity then look for too low of a temperature
setting. If eggs pip or hatch early (one day or more) then look for too high of a temperature. Eggs hatching early or late due to temperature are
probably within one degree of the proper temperature setting.
The No. 1588 Hova-Bator incubator is preset at the factory for about 100oF to 100.5oF. If this setting must be changed, there are switches located
in the access hole in the thermostat. The diagram below shows which switches to change in order to adjust the preset temperature. The maximum
adjustment up or down from the preset temperature will be no more than ½ to 1 degree.
