These instructions detail the installation and operation of your new Brinsea Advance Humidity Pump.
Please read them carefully before setting up your machine to achieve best results and keep these
instructions safe for future reference. Used in conjunction with the Ova-Easy and TLC Advance and
the Vetario SM and TM products, the Advance Humidity Pump offers convenient and refined control of
humidity.
FEATURES:



Continuous, permanent metering of relative humidity (%RH)
Proportional control easily set on incubator / brooder / intensive care unit
Sensor unit with high accuracy capacitive sensor
Pumped water flow - not level dependent
PRINCIPLE OF OPERATION
The sophisticated capacitive sensor provides a highly accurate measurement of the relative humidity
level within the incubator, brooder or intensive care unit. The Advance Digital Control System displays
this % Relative Humidity (RH) level on the LCD display.
The control system provides a signal to the Advance Humidity Pump to operate a tiny water pump
which transfers exactly the amount of water required into the incubator, brooder or intensive care unit
to maintain the required relative humidity which is set by the user. The control system compensates for
changes in ambient relative humidity level and, within working limits, will maintain a constant relative
humidity level.

Pump Installation (all models)
5.1
The Advance Humidity Pump is supplied with a length of the thick silicone tube to be fitted
around the pump rotor. This length will wear and need periodic replacement. It can also become
flattened if left unused for some time because the inside walls of the tube will stick to each other
around the rotor and prevent water passing through. Either replace this length of tube with a
new 160mm (6 1/3”) length or remove it and roll it between finger and thumb to ‘un-stick’ it.
Please note: The inner ends of the hose nipples must have a short (8mm / 1/3”) piece of the
thin silicone tube fitted first and the thicker silicone tube fits over the top.

Operation
The scope of these instructions is limited solely to the humidity control system. Please read the user
instructions supplied with the incubator, brooder or intensive care unit itself for full details of all aspects
of operation.
6.1
Fill the water tank to no higher than the bottom of the yellow moulding with clean water and fit
the rubber bung in the filler hole. DO NOT IMMERSE THE PUMP.
6.2
Read the operating instructions supplied with the Incubator / Brooder / Intensive Care Unit for
full details of how to set up and operate the product. Do not put any water in the water
reservoirs (only in the pump tank), set the vents to their mid position. Refer to the “Main
Menu Quick Reference” in the operating instructions.
6.3
Open the main menu by pressing the – and + buttons simultaneously.

6.4
If the humidity level in the cabinet is lower than the Set Humidity Level the pump will start to turn
and gradually draw water from the tank and pump it to the evaporation block. This may take a
few hours to stabilise after which the pump will run intermittently as the humidity level is
controlled.
6.5
The pump will not run if the incubator / brooder / intensive care unit is significantly below
the set temperature. This is to prevent the system adding too much water when the door
has been opened for inspection of eggs / animals etc.
6.6
The humidity level may fluctuate slightly about the Set Humidity Level by 1 or 2 %. This is quite
normal. Note that the humidity control system can only increase the humidity level, not reduce it.

Guidelines for egg incubation humidity levels
During incubation:
Poultry

40-50%
45-55%
Hatching
All species
60% RH or more
For more specific information on particular species’ requirements check the relevant literature.
7.1
To determine the correct humidity level for any given species either consult available literature
(a range of bird keeping and breeding books is available from Brinsea Products at the address
below) or experiment with different humidity levels and record which proved most successful or
weigh eggs during incubation. Eggs loose moisture through their shells and the rate of
evaporation depends on the humidity levels around the eggs. During incubation eggs need to
loose a fixed amount of water which corresponds to a loss in weight of around 13-16%
depending on species. By weighing eggs periodically during incubation it is possible to monitor
and, if necessary, correct humidity levels to achieve the correct weight loss.
Weigh the eggs on the day they are set in the incubator, take the average weight and plot this
on a graph (see example below). The ideal weight loss line can be plotted by joining the point
representing initial average weight with the ideal hatch weight (13-16% less depending on
species) with the x-axis representing the incubation period (in days).
By measuring actual average weights every few days the actual weight loss can be plotted and
compared to the ideal weight loss line and corrections can be made. For example if the actual
weight loss was greater than ideal (see graph below) then the air has been too dry and humidity
levels need to be increased to compensate.

Guidelines for brooder / intensive care unit humidity
levels
8.1
Relative humidity of between 45 and 55% RH is adequate for brooding chicks and will also
serve to help counteract dehydration in an intensive care scenario. Avoid very high levels as
condensation may form on cooler surfaces.

Routine Maintenance
9.1
Changing the pump tube:The peristaltic pump will need to have its tube replaced about every 3 months. Cut a length of
the thick silicone tube to about 160mm. Remove the connectors and pull off the old tube.
Replace with the new tube, avoiding twists. See 5.1 for details. Use the diagram on the product
label to thread the tube exactly as shown over the pump head. The tension must be sufficient to
ensure complete occlusion of the tube without unnecessary flattening between the pump rollers.
Adjust tube length as necessary. Ensure that the tube does not stick together if left for long
periods by unhooking it during storage.
9.2
Changing the evaporation block:Change the block as necessary to maintain good evaporating efficiency. Change the block
regularly to avoid bacterial contamination.
9.3
No lubrication or further servicing is required beyond the instructions above.
10 Troubleshooting
The control system may be set to control between 20 and 80% RH. In practice the minimum and
maximum levels of humidity achievable depend upon several factors, particularly the fresh air
ventilation rate. You may need to allow 24 hours for humidity to stabilise after making changes.
If you cannot get the level of RH you want, consider these notes:
10.1 Humidity will not go low enough:First increase the fresh air ventilation level. This will help to dilute the moisture given up by the
eggs or animals. There will still remain a lower limit determined by the moisture content of the
ambient air, particularly in warm humid conditions. This can only be countered by
dehumidification of the room air outside the incubator with proprietary dehumidifier but is rarely
a problem in practice except with ratites.
10.2 Humidity will not go high enough:Restrict fresh air ventilation to the minimum safe level. Remember even embryos need to
breathe!
Check that water is reaching the evaporation block when the pump runs – if not check the whole
length of the tubing for kinks and check that the tubing around the pump has not become
permanently flattened. If it has, replace the pump tube. Silicone tubing is very flexible but can be
damaged by sharp finger nails. A tiny perforation on the suction side of the pump will let in air
and prevent the pump drawing water.

11 Servicing and Calibration
11.1 In case of failure first check the signal cable is securely connected to the incubator / brooder /
intensive care unit.
11.2 Note that the pump will not run if the temperature in the cabinet is below the low temperature
alarm point (typically 3 degrees C. below set temperature).
11.3 The pump motor will only operate when an asterisk “*” is shown next to the RH% display. If this
is not shown check the Set Humidity Level referring to section 5. The asterisk and pump output
are only on when the measured humidity is lower than the Set Humidity Level. The pump output
is switched on intermittently once the measured humidity is within a few percent of the Set
Humidity Level.
11.4 The pump motor is easily replaced if necessary using basic tools. Instructions are supplied.
11.5 The digital humidity sensor is individually calibrated during manufacture but may be recalibrated if required. It is not recommended that this procedure is carried out by the user.
