Installation, user and maintenance manual – GAHP-GS/WS 4 NORMAL OPERATION In this section you will find all the indications necessary for the activation, regulation and control of operation of the appliance depending on the type of installation and control setup. • TYPE A: controlled by CCP (see Figure 6.4 Comfort Control Panel e Accessory → 48, detail CCP). • TYPE B: controlled by DDC (see Figure 6.3 CCI/DDC → 47). • TYPE C: controlled by consent switch (e.g.
TYPE C: STANDALONE APPLIANCE Standalone appliances must be activated and deactivated only by means of the consent switch provided by the electrical installation technician. According to requirements, this consent switch may be an on/off button, an ambient thermostat, a programmable timer, or one or more voltage free contacts controlled by another process. For details about the type of on/off command installed, contact the plant’s electrical installation technician.
Installation, user and maintenance manual – GAHP-GS/WS For the operating codes generated by the CCP/DDC, refer to the manuals supplied with the unit. Operating codes generated by the electronic board during the start-up of the appliance If the appliance remains inactive for a prolonged period, it is possible that air is present in the gas pipes. In this case, activation fails and the appliance reports the operating code: "u_12" - flame controller arrest (temporary) (see Paragraph 9.

To set new values for the parameters, see Paragraph 5.8 PROGRAMMING OF HYDRAULIC PARAMETERS → 42. Menus 4, 5, 6 and 7 exclusively concern the installation technician and Robur’s authorized Technical Assistance Centre. Menu 8 may currently be selected, but not used. Display and knob The controller’s display can be viewed through the glass of the viewing aperture on the front panel of the appliance.
7. I n the same way: turn the knob to scroll through content (menus, parameters, actions), press the knob to select/confirm the content (access a menu, display/set a parameter, execute an action, quit or return to the previous level). For example, to quit the menus, turn the knob to scroll through menus "0.", "1.", "2." etc. until the controller displays the quit screen "E"; now press the knob to quit. In the case of menus 0 and 1, the user can view any parameter.
Installation, user and maintenance manual – GAHP-GS/WS To reset the flame control unit select menu 2, as indicated in the Paragraph "Accessing the Menus"; then proceed as follows: 1. The display shows: "2." press the knob to access the menu. The display initially shows item "2. 0". 2. Press the knob to display the flashing reset request: "reS1". 3. Press the knob again to reset the flame controller. The reset request stops flashing, and again the display shows "2. 0".
4.5 PROLONGED PERIODS OF DISUSE When the appliance is to be inactive for a long period, it is necessary to disconnect the appliance before the period of disuse and reconnect it before it is used again. To carry out these operations, contact a reputable hydraulic system installation technician. Disconnecting the appliance You will need: the appliance connected to the power/gas supply. Necessary equipment and materials. 1.
Installation, user and maintenance manual – GAHP-GS/WS In case of winter saesonal switch-off or long period of stopping, we suggest to not empty the hydraulic circuit: in that case possible oxidation process can occur.This oxidation process could damage both the hydraulic system and also the Robur heat pump.It’s important to verify that no leakages occur in the hydraulic circuit that may empty part of the system.
5 HYDRAULIC INSTALLATION In this section you will find all the instructions necessary for installing the appliance from a hydraulic viewpoint. The hydraulic system installation technician must consult the electrical system installation technician in order to decide upon the correct sequence of the operations to be carried out. Before realizing hydraulic system and gas supply for the appliance, the professionally qualified personnel is advised to read Paragraph 3.
Installation, user and maintenance manual – GAHP-GS/WS The lifting crane and all accessory devices (braces, cables, bars) must be suitable sized for the load to be lifted. For the weight of the appliance, consult Table 3.1 GS HT/LT technical data → 12 and Table 3.2 WS technical data → 13. The manufacturer cannot be held responsible for any damage occurring during the installation of the appliance. Figure 5.
Minimum clearances are necessary in order to be able to carry out maintenance operations. The fumes outlet terminals must be installed in such a way that they do not allow the fumes to collect or return to the circuit in the unit's installation area. The outlet terminal must be constructed in conformity with established regulations. Figure 5.2 – Clearances Place the appliance preferably far from environments where silence is required, such as bedrooms, meeting rooms, etc.

ISOLATION BALL VALVE on the water and gas pipes of the installation. 3 BAR SAFETY VALVE installed on the outlet water pipe. PLANT EXPANSION TANK installed in the appliance outlet water pipe. EXPANSION TANK for the individual appliance, installed on the water outlet pipe (primary side).
Installation, user and maintenance manual – GAHP-GS/WS LPG may cause corrosion; piping and fitting materials must be resistant to this corrosion. Vertical gas pipes must be equipped with a siphon and provided with a drain for the condensate that may form inside the pipe during cold periods. It may also be necessary to insulate the gas pipe to prevent the formation of excessive condensate. In any case, provide an isolation valve (ball valve) on the gas supply line, to isolate the appliance when required.

Installation, user and maintenance manual – GAHP-GS/WS 5. R econnect the plastic pipe E and secure it with its clamp. 6. Fit the bottom left side panel. If the appliance is operated with the siphon empty, there is a risk of leaks of exhaust flue gas. OUTDOORS UNITS The fumes condensate outlet is on the left of the appliance. The distance L between the coupling and the base may not exceed 110 mm. 1.
• • • s ized to ensure a slope of 10 mm per metre of length; if this slope cannot be achieved, a condensate pump must be installed near to the discharge; realized in such a way as to prevent icing of the condensate; mixed, for example, with domestic effluents (washing machine, dishwasher, etc.), usually alkaline, acting as a buffer solution before discharging into the sewer. Do not discharge the condensate into the guttering, since it may ice and corrode the materials normally used for gutters. 5.
Installation, user and maintenance manual – GAHP-GS/WS 3. F ill the hydraulic circuit to at least the minimum amount and add inhibited monoethylene glycol to a volume percentage in proportion to the minimum winter temperature in the installation area (see Table 5.3 Technical data for filling the hydraulic circuit → 36). Robur recommends using inhibited corrosion resistant monoethylene glycol.
To facilitate the operation of bleeding air from the hydraulic circuit, the appliance is equipped with an additional manual air bleeding valve. Use of glycol antifreeze Glycols, normally used to lower the freezing point of water, are substances in an intermediate state of oxidation which, in the presence of oxidising agents such as oxygen, are transformed into corresponding acids. This transformation into acids increases the corrosive nature of the fluid contained in the circuit.
