IV Installers manual
This section of the manual provides the
information needed to install, program and
maintain the Aquacom unit correctly. Information
about errors and reports can be found in section
five.
Put your contact details on the back of this
manual, after installation.
Always follow the following requirements
at the installation:
- Installing, operating and effectuating
maintenance of the Aquacom must always be
done by a certified installer, unless minor
maintenance is concerned and is indicated as
such in this manual.
- During installation the local and general
applicable building, safety and installation
instructions of the municipality, utilities and
other agencies must be abided.
- There should not be made any modifications
to the Aquacom.
- Never turn on the Aquacom without glycol-
water mixture in the system. This can damage
the pump.
4.1 Mounting of the Aquacom
The Aquacom is designed is such way that only one
version is needed for all possible situations. The
incoming air flow duct has to be attached on the
same side as the pipes for the water glycol mixture.
The outgoing air flow duct can be attached either
on the top or on the side.
The Aquacom unit needs
to be attached to the suction side of the fan at all
times.
This benefits both the efficiency of the
Aquacom heat exchanger and the required fan
power. Also with connection of the Aquacom to
the press-side of system D ventilation, the
recovered heat from the exhaust air would be
transferred to the glycol water mixture in winter
operation.
The way the Aquacom unit will be mounted can be
chosen on the spot. The unit will standard be
delivered in the recommended configuration for
maintenance. If you wish to change this
configuration, you have to follow the next steps:
-
Remove the four M8 cap nuts together with
the four rings.
- Remove the four rubber caps from the threads
on the other side
- exchange the brackets of the side and place
back the rings, the cap nuts and the rubber
caps.
- Check whether the brackets are attached
correctly and whether its positions are correct.
- Remove both covers which are fixed by the
clip closures.
- Remove the cable of the control unit from the
cable tie attached to the sheet metal.
- Remove the three screws with which the
control units housing is attached to the unit.
Beware, the housing will not be attached to
the unit anymore.
- Also remove the fourth screw. The control unit
needs to be attached here on the other side.
- Turn the control unit to the other side of the
unit without damaging the cables and screw it
on the other side. Make sure you attach the
cable tie with cables to the sheet metal again.
- Rotate the manometer clockwise so it can be
read from the other side.
- Rotate the measuring scale of the flow meter
so this can be read from the other side.
- Carefully press the blind cover with isolation
out of the rear cover (cover without sticker).
- Place the blind cover with isolation in the front
cover (cover with Aquacom sticker).
- Place both covers back on the unit.
4.1.1 Installation of the glycol-water ducts
Before you start installation of the ducts, draw a
plan how to install the 200m hose. This way you
will never have too much or too little of the hose.
Keep the following things in mind when drawing
the plan:
-
Use PE hose with an outer diameter of 25mm,
Comair supplies the correct hose (Art. nr.
1230703).
- The maximum applicable hose length is 200m.
- The hoses are 100m length per hose. These
can be connected using a PE coupling (Art. nr.
1230704). For proper assembly of the
coupling, see appendix I.
- Try to draw the plan in such way that the PE
coupling is inside the house. If this is not
possible, indicate the coupling clearly in the
plan.
- Mind the local regulations when placing the
duct, and assure yourself whether you need a
permit to place a horizontal ground heat
exchanger with a glycol-water mixture. Some
municipalities also indicate a maximum depth
for the duct network.
