Firstly, we sincerely thank you for purchasing Rcom MARU H&B.
It has been designed to analyze airflow using built in digital technology to maintain an optimal environment within the
MARU H&B cabinet. The incubation parameters are controlled using purpose built control systems coupled with high end
sensors, all in order to permit optimum results. However, best results occur when the user, couples personal knowledge
of the machine and of incubation and hatching along with observation skills with the Maru H&B sensing, automation
and control systems. The machine needs your help, good breeding flock, healthy flock diet, fertile eggs , reasonable
incubation room environment and a ‘clean’ power supply in order to provide excellent results. User’s knowledge of the
machine and manage the MARU H&B are very important. Certainly, the Maru provides an optimal incubation environment
but parameters need to be managed, i.e. temperature and humidity depends on egg species, environment, and capacity.
Moreover, the Rcom MARU H&B has been carefully designed to provide an optimal setting and or hatching environment,
therefore, before using the incubator, we strongly recommend that you read the manual carefully.

What is an Incubation Room?
The Incubation Room is a confined space for setting and operating an MARU H&B efficiently.
An Incubation Room environment has a considerable effect on hatch rate. Controlling the MARU H&B
environment is recommended; there should be little noise or vibration and constant temperature ranging
upwards from 28℃(82.4℉) with small variation in temperature. For optimum performance, pay attention
that your MARU H&B isn’t exposed to temperature drops compared with daytime. Do not directly exposed the
MARU H&B to sunlight during daytime. also, please MARU H&B where direct wind from air-conditioner not to reach.
If you set a high temperature, condensation will occur and may causes water to leak from the machine and
it which is not a technical problem. You need to keep temperature between 28℃(82.4℉).
Do not place water container on top
of the machine. It may flood the
humidity nit.
How to Install the this MARU H&B
▶Please set the machine horizontally on a stable, tallish
table (50[cm] or above)
▶Ensure the machine is completely level, so the door can
close completely.
▶Connect silicon tubing onto the nipple of machine, and
the other end of silicon tubing into a water container.

▶When hatching, humidity should be relatively high to prevent the thin membrane from drying out or hardening
before hatching.
▶When hatching, it's recommended not to open the door often.This is because if you open the door often humidity
will be rapidly decreased and it will take a long time to regain the proper humidity.
▶It's very important to maintain humidity higher 1~2 days before hatching than the early and middle incubation
periods. Humidity requirements during incubation are RH 45~55% for waterfowl, RH 40~45% for poultry and
RH 35~45% for parrot, in general. One day before hatching, all kinds of birds need about RH 65% humidity
and sometimes need higher than that. However, in areas of high ambient humidity, lower levels of humidity may
be needed during incubation.
▶Air Controlling Lever : Outer fresh air can be flowed into machine inside without affecting insulation. When eggs
start hatching, open air controlling lever either fully or half-open.
▶If the temperature where machine installed is high, it will effects to tmachine setting temperature.
In this case, you are able to adjust temperature by Air ventilation on the top of machine.
machine internal temperature is 37℃(98.6℉) or more, and hatching room temperature is below 28℃,
in that case, RH 70% humidity is may not be able. The difference of ±5% humidity value may occur
from the humidity sensors difference, and there are no problems at hatching.
If you set high temperature, condensation will occur the near Air Vent and may causes licking water from the
machine and it is not a technical problem.

▶Feed should be regularly replaced with new and uncon
taminated feed. For young chicks, yolks from boiled eggs
should be crumbled, mixed with grains or vegetables and
fed for good results. As there are some differences in chick
feed for each kind of bird, it is desirable to obtain useful
information about the chicks before hatching. (Please
refer to Rcom website for helpful information on birds)
If you put too much water into drinkers, chicks could
fall into the water bowl and their wet feathers can cause
hypothermia, leading to the death of the chicks.
In this case, dry the wet feathers with a hair dryer.
▶Chicks incubated from the hatching Room should be
relocated to the brooding space located in the lower section
of the device. The temperature for the H&B cabinet should
normally be 37℃(98.6℉)
▶The H&B cabinet should always be clean. By lining the
brooding room with sawdust, wood shavings or finely cut
paper, chances of contamination can be reduced.
Also, the opening of the water bowl should be covered in
a shape of “+” with a tape. (To prevent chicks from falling
into the bowl)
▶Temperature management : Start from 37℃(98.6℉),
lowering the temperature by 1~2℃(1.8~3.6℉) every
week to adapt the chicks to the external temperature.
Chick Observation is important during brooding as is
cleanliness.
▶Humidity Management : Even if the humidifier is not turned
on, the humidity of the H&B cabinet will be high due to
hatching chicks. Please open the Air Vent to the maximum
setting.
▶Clean all the contaminants off the cabinet floor and replace
sawdust, wood shavings or finely cut paper.

▶If you turn the machine off and then leave the machine
door closed after high humidity hatching and brooding,
accumulated moisture inside the machine evaporates and
sticks to electric and electronic circuits. This could cause
problems, be sure to open the machine door and completely
remove moisture inside of machine.
Instructions for Disassembling and Cleaning
Power cord must be removed from the outlet of the
machine.
▶Remove all the remaining water from the
humidity unit.
▶As shown in the picture, unscrew 6 screws
located in the corners of the machines
cover with the screwdriver and open the
cover.
[ Cleaning the Controller Unit ]
If there are any dirty substance(scale)
in the humidifier unit and pan, it must
be removed.
▶dirty substance(scale) can form in the
humidity unit and pan should be removed
by using a vacuum cleaner, brush and/or
further cleaning aided by vinegar.
If a lot of dirty substance(scale) has
formed in the humidifier unit, soaking
it in vinegar overnight will neatly clean
the humidifier unit.
If a lot of scale has formed it is likely you
are not using distilled water, please use
distilled water as it prolongs machine life.

[ Cleaning the Temperature,
Humidity sensor ]
▶This sensor part lies in upper part inside
the machine, behind the controller
assembly but in front of the fan/heater unit.
Occasionally, fluff, feathers, dirt (Dander)
or water disturbs the accurate measurement
of temperature & humidity. Please clean Dander
away with a soft brush.
▶Reassemble in the reverse order of disassembling and
store machine safely in a cool dry place.
Feather Dander and dust can clog up or foul circulation fans; this can make the fans noisy and also destroy
the fans. It is very important to clean your machine, for maintenance reasons and also to increase incubation
success.
Be careful not to allow moisture into the power connecting
parts on the rear of the machine.
Do not clean the machine with benzene or thinner.
There is a risk of transformation or dis-colorization.
After several hatching, dust or bird feathers (Dander) can build up in the mechanisms, controller and humidity
unit and cause incorrect operation or malfunction. So, ensure you clean the incubator carefully after each
hatch. (The life span of the humidity unit can be reduced when used without cleaning.)
[ Cleaning the Incubator Cabinet]
▶After hatching, remove egg basket and divider inside of machine, and clean the inside with vacuum cleaner.
Tiny dust should be removed with brush again.
▶Clean the egg basket and dividers, brooding box with
water and an antiseptic solution, and then dry naturally
or operate machine temporary to dry them.

is low
▶Inspect the egg to check possibility
of egg surviving.
▶Disinfect the machine.
▶Check all settings of machine.
Especially, check them focusingon the
temperature.
▶Review care of health of mother bird.
