1. Realize that by replenishing the system the glycol content will fall Therefore measure the glycol percentage as indicated in the next paragraph If the pressure falls to quickly the system leaks and the leak will need to be traced and repaired Also the pressure of the expansion vessel needs to be guaranteed On the side of the vessel a valve is located The vessel needs to be pressurized to 0 5 bar in advance 4 4 2 Check the glycol content Using a glycol refractometer the glycol percentage in the system can be measured Drain a small amount of the glycol water mixture using the filling unit and measure the glycol percentage When the unit installation is completed the glycol percentage needs to be at least 30 but not more than 50 considering the gaskets and parts Prevent freezing due to a too low glycol percentage Anti freeze can be added using a submersible pump For anti freeze use a non toxic biodegradable mono propylene glycol with anti corrosion and anti foam additions which will not affect the seals metals and plastics Art nr 1230739 The next figure shows the temperature at which the glycol water mixture will freeze for every glycol percentage Freezing point water glycol mixture Freezing point water C Percentage glycol in water 16 4 4 3 Check the heat exchanger Open the front cover Then check if the fins are not bent and or the seams are not open Also check whether the cop2. Major maintenance on the unit was committed by an unauthorized maintenance technician 4 There are signs of abuse or modifications on the device 5 Changes to the system have been made after completion of the installation 6 Improper tubing is used 7 Too little or improper anti freeze is used 2 7 Liability The Aquacom is designed as an addition to a balanced ventilation system The unit has to be placed in a dry frost free area Any other use is unauthorized and is considered as improper use For damage or injury resulting from this improper use of the Aquacom Comair cannot be held responsible In addition Comair BV not liable for damage or injury resulting from failure to follow safety operating and maintenance instructions as specified in the installation manual 2 8 Deliveries All deliveries are subject to the general conditions of METAALUNIE Afree copy will be sent to you when requested III User s manual This section of the manual provides the information to operate the Aquacom correctly what to do with an error and how to effectuate maintenance NOTE Always remove the plug from the wall socket before servicing the unit 3 1 Controlling the Aquacom Aquacom is standard equipped with an Aquacom digital operating panel which is integrated in the front of the unit The installer has installed the operating panel on the correct side The control panel looks like the following figure failure

6. homes are increasingly insulated and made airtight If you do not ventilate adequately in such an airtight house problems with moisture and even mold will occur These problems do not arise from too much insulation but rather from insufficient ventilation A lot of humidity in a house is also created because people breathe and perspire cook wash and shower Besides that CO2 is liberated when we cook or heat water on gas Poor ventilation is dangerous and unhealthy To counter CO2 poisoning mold and dust mites and to create a healthy environment you have to ventilate adequately 2 2 System D with ground heat exchanger System D with heat recovery HR stands for balanced ventilation through mechanical supply of fresh air and mechanical removal of contaminated air by fans The exhaust air passes through a heat exchanger during winter and there it heats the fresh air The fresh heated air is then blown into the house In the summertime it is possible to bypass the heat exchanger at night so that fresh air can be supply without being heated by the exhaust air bypass If the house is cooler than outside the heat is kept out by the heat exchanger The main advantage of this mechanical ventilation system is that the energy from the exhaust air is used to heat or cool fresh air This represents substantial energy and cost reduction compared to natural ventilation or system C To preheat the fresh supply air during wintertime a ground
