4.1. ACOUSTIC INSULATION
Sound absorption
Sound is reflected by hard materials. Soft, porous materials are best suited for sound absorption. A combination of different materials can reduce the reflection of sound.
Contact noise insulation
Sound travels very easily through hard materials. Soft rubber material can be used to reduce contact noise. The effect of this insulation strongly depends on:
–  installation method: make sure that vibrations cannot be transferred between different elements, e.g. between the built-in heaters and other metallic parts, through pipes, along air ducts etc.
–  installation of acoustic insulation in hollow acoustic spaces. Avoid cavities between insulation and pipes.

GENERAL INFORMATION

DANGER!
The unit is not intended for industrial applications.
Do not insert objects into the supply and return air openings.
IMPORTANT!
–  the unit will only function correctly if the installation and operation manual is strictly followed.
–  all clearances indicated in the manual must be respected in order to guarantee performance, and to allow installation and maintenance.
–  in case valve packages are to be installed, make sure that there is enough room left.
–  periodic access to the unit is required for inspection, maintenance and repairs.
–  pay attention to the signs and symbols indicated on the fan coil units.

Unit identification:
The serial number is tagged on unit’s right side (on the left if the connections are on the unit’s right side).
Information regarding unintended use:
The unit has been designed to function as a fan coil for both heating and cooling applications; any other use is strictly forbidden. Installing the unit in an explosive environment is prohibited.
Decommissioning:
When the unit is not used for long periods of time, it must be disconnected from the mains electrical connection.
If the unit is not used during the winter period, the water in the system may freeze. A suitable quantity of anti-freeze liquid should be mixed with the water.

OPERATING LIMITS

If the fancily unit is supplied with chilled water, condensate from the coil will be drained via the condensate drain connection.
At water temperatures below dewpoint, condensation may occur on components other than the coil. This is not collected in the condensate drain, and might drip from under the unit. Therefore the supply, return and drain pipes must be insulated. In case the valve package is installed next to the unit, the valve package must be insulated.
In order to avoid any condensation, the water temperature should be kept above the dewpoint. Output must be calculated based on the actual water temperatures and ambient air condition.

Allowed minimal water temperatures before condensation occurs.

INSTALLATION

–  Step 01 through 04 is only applicable to the wall. From step 05 the installation is identical for all Brisa Built-In and Surface mount units.
–  respect the open room around the unit as shown in the manual
–  insulate the valves and connections and pipes with self-adhesive thermal insulation against condensation or install secondary drain pans
–  slope the fancily unit slightly towards the condensate drain to help the water drain

Mark the screw holes, use the unit as a template or according to the dimensions specified on page 8 and 10 in this guide.

The type of wall determines what type of screw or plug should be used.
For installation on drywall: make sure that the mounting holes line up with supporting studs.

9.1. HYDRAULIC CONNECTION
The hydraulic connections must be carried out by qualified staff.

Connect the unit to the hydraulic system with the indicated inlet/outlet connections. Make sure the connections are air tight with a sealant.
–  all coils (including the secondary coil) are equipped with an air vent near the top connection and a water drain near the lower connection.
–  it is recommended to bleed air from the coil before operation.

Setting up the condensate drain:
The condensate drain pipe must be installed with an adequate slope to make sure the water drains properly.
The supply and return pipes for chilled water and their valves must be insulated against condensation.
Any piping downstream from the fan coil is the responsibility of the installing contractor and must comply with local jurisdiction requirements.

The condensate drain system must be set up with an adequate p-trap in order to prevent odors.
Always install a plug for cleaning in the lower part of the p-trap in order to allow quick disassembly.
Position the drain pipes without mechanical stress on the drain connection of the unit.
OPTION: secondary drain pan for Brisa Built-In Ceiling
BRIZA H38: ref. 5127.00010001 / BRIZA H52: ref. 5127.00010002

Once installation is complete:
bleed the air from the coil make sure that there are no water leaks
insulate the valve connections and pipes with self-adhesive thermal insulation against condensation or install secondary drain pans .
pour water into the condensate pan and check if the liquid is drained properly. If not, check te inclination and look for possible blockages.

9.2. ELECTRICAL CONNECTION
IMPORTANT!
The electrical connection of the unit must be carried out by a certified technician , in compliance with the local building codes. Non-conforming electrical connections releases Jaga N.V. from liability concerning damage to objects and persons.

DANGER!
–  check that the voltage to each unit is 24VDC. The unit is designed for Direct Current only. In case 24AC comes to the unit, a suited rectifier must be installed.
–  make sure that the power supply covers the total load of all units connected plus a margin of 10% to cover the start-up power.
–  if the unit is mounted on a metal surface, the ground connection must be installed in compliance with local regulations. The ground conductor must be longer than the other conductors so that it is the last one to release in the event the
connection comes loose.
–  verify if the supply cables are of adequate section for the maximum current required.

9.2.1. Option: Electrical connection – 0…10V

It is important to have a common ground on all power supplies used for power and control signal (for example from BMS or thermostat with speed control).

INITIAL START

IMPORTANT!
Start-up and Commissioning of the fancily must be carried out by skilled staff, qualified to work on this type of product.
DANGER!
Before start-up, make sure the installation has been carried out in compliance with in this manual.
Before start-up the fancily unit, check if:

1. the unit is positioned correctly
2. the supply and return pipes are properly connected and insulated
3. the pipes are clean and air is removed
4.  the inclination of the unit towards the drain and the p-trap are correct
5.  the coils are clean
6. the wiring connections are correct and properly tightened
7.  the supply voltage is correct
8. the electric power consumption is correct and does not exceed the maximum value indicated in the catalog

MAINTENANCE

DANGER!
–  maintenance must be carried out by qualified technicians.
–  do not insert sharp objects into the supply and return grilles
–  the unit has sharp edges; use gloves during maintenance!

DANGER!
Always use the main disconnect switch to isolate the unit from the mains before carrying out any maintenance or inspection work. Make sure that no one accidentally turns on the power to the unit; lock the master switch in the off position.

11.1.SPECIAL NOTE
Maintenance and cleaning of the stainless steel protection grille:
a dirty grille obstructs the air flow, so clean the grille at regular intervals, depending on the room’s purpose and how it’s used. The grille should never be disassembled for maintenance and can be easily cleaned by using a vacuum cleaner.
Cleaning the unit:
always disconnect the power supply before servicing the fan!!
–  cleaning at regular intervals is important, depending on the room’s purpose and how it’s used
–  clean with a vacuum cleaner or air compressor. Do not use solvent- or detergent based products.

11.2.ROUTINE MAINTENANCE
Every 6 months: Check the condition of the coil and condensate drain:
If necessary:
–  remove any dirt from the coil surface
–  remove dust using an air compressor
–  wash with water and brush gently
–  dry by using compressed air
–  keep the condensate drain free from any obstructions that may prevent normal water flow

Bleed air from the system.

1. start the circulation pump and open the supply valve for a few minutes.
2.  stop the circulation pump.
3. loosen the vent screw on the inlet collector and bleed the air.
4. repeat steps 1 to 3 until there is no more air escaping the system

11.3.ELECTRICAL CIRCUIT
The following steps are recommended to perform maintenance on the electrical circuit:
–  check the unit’s power consumption using a clip-on meter and compare the reading with the values shown in the documentation;
–  inspect the electrical contacts for corrosion and loose wires.
