Installation instructions
Installation and hydraulic connections (Fig. 5)
Prepare a recess in the wall having the correct size (refer to Fig. 1)
(a)
Position
EQUICOMPACT
into the centre of the recess
(b)
Remove the heating unit insulation (if provided)
(c)
Connect return piping both to the primary and to the secondary side of the heating unit
(d)
Connect flow piping both to the primary and to the secondary side of the heating unit
Warning
. The contact with high-temperature fluid can cause even serious scalding. Use the adequate personal protection equipment (PPE).
(e)
Open the four (two red and two blue) heating unit shut-off valves
(f)
Remove the plug from the static balancing valve by means of an 8-mm Allen key
(g)
Drive the valve fully open, making sure that the incision is parallel to the flow direction
(h)
Wash the plant
(i)
Close the red shut-off valves of the heating unit
(j)
By means of an 8-mm Allen key, remove the plug sealing the strainer housing. Remove the strainer cartridge, wash it carefully, the put
it back into the housing. Put the plug back and tighten it.
Installation of meters (Fig. 6)
(a)
Close the shut-off valves of the heating unit
(b)
Loosen the nuts at the endpoints of the template, then remove it. Position two new gaskets and the heat meter instead of the template,
then tighten the nuts without forcing too much
Warning
. Pay extreme attention to flow direction. A wrong installation of the heat meter precludes the correct metering and may damage the device.
(c)
By means of a 15-mm wrench, unscrew and remove the plug from the sensor pocket (3 in Fig. 3) and insert the heat meter flow sensor
by following the instructions provided by the manufacturer of the device
(d)
Seal the meter and the flow sensor
The following steps must be carried out only if the application requires the installation of one or more volumetric meters, and should be repeated for
each domestic line.
(e)
After checking that both the shut-off valves of the domestic line are closed, loosen the nuts at the endpoints of the template, then
remove it. Position two new gaskets and the water meter instead of the template, then tighten the nuts without forcing too much
(f)
Seal the meter.
Commissioning (Fig. 7)
According to the designer specifications, make the static balancing of the user plant by following these steps:
(a)
Open the heating unit shut-off valves
(b)
Slowly adjust the balancing selector position until the design flow rate is showed by the heat meter display
Warning
. If the installation is to be equipped with dynamic balancing devices, either flow stabilising valves or differential pressure controlling valves can
be installed outside
EQUICOMPACT
unit. In case of differential pressure control valve for return mounting, a dedicated pocket (5 in Fig. 3) can be used
for the connection of the high-pressure capillary probe. The connection thread is soft-seal M10x1.
(c)
Once the adjustment has been completed, put back the plug
(d)
Seal the valve using of the proper holes
(e)
Open all the shut off valves, both on heating and domestic lines
(f)
Put back the insulation shell (if provided).
In case of plastering-ready door, plaster the door aside. Complete the necessary masonry operations, then put back the plastered door once the work
is over.
Other accessories
Zone valve 4 in Fig. 3 can be controlled by an actuator wired to a room thermostat. IVAR offers normally closed electro-thermal heads cod. 501508
(230 V) or cod. 501524 (24 V) together with chrono-thermostat cod. 580012 (heating only) or cod. 580015 (heating/cooling). These components can
be purchased separately.
Warning
. Follow the dedicated instructions of the electronic devices for their correct installation. In particular, if normally-closed electro-thermal heads
with “first open” function are installed (see cod. 501508 or cod. 501524), please consider that such devices are delivered in open state. This function
is permanently disengaged after the first 6 min of powered use at the working voltage. Once the initial cycle has been completed, the head will be
regularly open when powered, and closed otherwise.
