Accessories Electrical preheating element for frost protection In longer periods of sub-zero temperatures, the high-efficiency counterflow heat exchanger will ice up. To avoid icing, it is recommended that an electrical preheating element is mounted. The preheating element uses very little energy, but ensures efficient heat recovery without de-icing, thus achieving an overall saving in energy consumption.
The hot water tank is heated by the central heating system’s heat pump and/or via solar panels. The water runs from the SHW tank, through the DHW tank in Compact P, before running into the domestic hot water supply.
When lifting the units with the supplied straps, these must be at an angle of max. 45° from the vertical. Nilan also offers a lifting trolley, with which the unit can be lifted directly off the pallet and into the building. If the filter box is removed, the unit can be manoeuvred through an ordinary door.

10 is activated and turns a tree-way-valve, so the brine water is led tod the fan coil (the fan coil is not a Nilan delivery). When the contact is switched off again, GEO will go back to normal operation. If there is a need that GEO must produce domestic hot water, the passive cooling will still be running, even with higher effect, because the brine water will be cooled by the heat pump, when it is producing domestic hot water.
Plumbing installation Condensate drain Important information Compact P is supplied with a reinforced 20 mm condensation drain pipe with built-in water lock. ATTENTION Install the condensation drain with an even slope of minimum 1 cm per metre to the nearest drain.
All work must be performed by qualified personnel and in accordance with relevant legislation and provisions. Nilan's hot water tanks are double-enamelled, ensuring long life. The efficient foam insulation protects against unnecessary heat loss. All connection nozzles for water have 3/4" thread and are located in the tank bottom.

Plumbing connections for accessories Safety group CAUTION A safety device must be connected to the hot water tank. When water is heated to 60 °C, it expands by 2%. A pressure tank could burst without a safety valve keeping excess water out. The safety valve should therefore drip during warming up. Installation: The following should be remembered during installation: The double nut is attached to the water heater’s cold water...
The control system contains as standard a temperature limit for domestic hot water of 65 ºC. This setting prevents users from scalding themselves when the hot tap is turned on. It also means that when Compact P is in cooling mode, cooling will stop when the domestic hot water reaches a temperature of 65 ºC.

It is important that all circuits in the central heating system are open during filling.
Emergency operation Emergency operation domestic hot water If an error occurs in the controller or components in the Compact P, and the unit therefore stops, it will not be able to produce domestic hot water. If the installer is not able to come right away or the error happens outside the opening hours, and you therefore cannot contact the installer, there is a possibility to get hot water by setting the unit into emergency mode.
