1. User instructions 1.1. General information Congratulations on your purchase of heat pump Hotjet. Get familiar with these instructions to get the best use and a long service from the pump. The heat pump is a compact unit designed for heating water for hot service water and for heating. The source of heat is the external air, of which heat is transferred to water in an exchanger. The heat pump is a long service life and a very safe product. We wish you a trouble-free operation and a lot of thermal comfort.
Principle of operation of heat pumps: 1.1.2. Warning BEWARE: The device contains electrical components under tension. The device may be opened only by a person with relevant electrical qualification. Risk of electric shock. ! The power supply circuit of the heat pump must comply with standard ČSN 33 2000 ! We recommend installation of an 30mA tripping current earth leakage relay (ČSN EN 60335-2-40 ed.) and a lockable main switch.
be exposed to high temperatures and the danger of perforation. ! Hot water above 52° C temperature may cause serious burns or death by scalding. ! Never remove or cover any of the markings, labels and warnings placed on the heat pump, as these should be visible at all times. Replace the damaged ones with new ones. ! The control panel must be out of reach of children. ! Be careful to avoid injuries on sharper edges and projections.
2. Installation Instructions This part of the documentation is intended for qualified installation and service staff as an assistant for proper installation, operation and maintenance of the heat pump HOTJET. Read it carefully, failure to comply with instructions may lead to malfunctioning of the heat pump, damage to property, scalding or electrocution injuries. 2.1.

2.3.2.Space for installation model 300mm The heat pump is designed for installation in the house - utility rooms, cellar, garage, land, and the like. Installing the indoor unit on the construction over 50% humidity can cause condensation on the cover of the pump or air-duct. For service approach to be followed by a minimum distance diagram: Connected Heating System 600mm Electrical outlets Service access 300mm • 2.3.3.
2.3.4.Model , base and pedestal • Place the heat pump on a solid surface, which preferably consists of a concrete base, concrete footing or paving • It is not advisable to place the heat pumps on larger areas – e.g. parking lots, pavements - as these do not muffle noise well. • Install the heat pump at least 0,3 m above the surface.

3. Technical data of heat pumps Hotjet 3.1. Technical data of heat pump Hotjet “ i “ • The condensate drainpipe can be carried out into sewerage Source of heat: suction air Installation position garage, cellar, workroom, utility room, farm building Characteristics External part of installation: there is none, just holes in the wall and covering grate/shutter on the facade New generation of heat pumps hotjet “i” is highly functional while the price is still unbeatable.
• • May be charged equithermally May be charged, so-called, forcedly, when it is charged up to the required temperature. Startup of this function may be linked to switching electrical energy rates, certain time or it can be controlled by external command. One of the advantages is the possibility of “collection” of heat when the conditions are better. For example the air temperature is higher.
