Page 23: Plant Circuit Unloading
Inverter air/water chillers and heat pumps with floor‐standing and remote condensing units i‐SHWAK V4 During the operations of loading/topping up, the plugs of the air vent valves must be partially unscrewed to allow air to flow freely out of the valves. The MAR/MARS models are equipped with two air vent valves; one is installed on the single puffer in correspondence to the three‐way valve. The MARP/MARPS models are equipped with three air vent valves, one for the DHW technical side puffer, one on the plant side, and the other near the three‐way valve. Refer to position 2 of the Paragraph 25.1 and the Paragraph 25.2. (2) Stopper of the air vent valve When it’s necessary to top up the circuit of the plant or to adjust the title of glycol (in the cases described in Chapter 22), you can use the service valves.

Inverter air/water chillers and heat pumps with floor‐standing and remote condensing units i‐SHWAK V4 Do not put both pipes in the same protecting sheath, in order to ensure the correct operation of the plant. Do not carry out the connections by using ordinary hydraulic pipes that might contain inside themselves residues of chips, dirt, or water which can damage the components of the unit and alterate the correct operation of the equipment. Use only specific refrigeration copper pipes that should be provided clean and sealed at the ends. Use only pipes with correct dimensions of diameters; refer to the table of the technical data in the chapter 14. Cut the pipes with wheel pipes cutter, clutch slowly paying attention for not to crush the pipes when using the tool. Never use an ordinary hacksaw because shavings could go into the pipe and then circulate in the system which can seriously damage the components. After cutting the pipe, please seal immediately the opening on both ends of the roll and cut pipe. The equipment does not require any additional refrigerant. The refrigerant pipes should be straight as possible and the necessary bends must have radius more than 300mm. Plug the opening on the ends of the pipes before inserting them through the hole in the wall. The refrigerant piping and joints must be thermally insulated to prevent heat losses. You should avoid the introduction of non‐condensable gases (air) into the circuit, otherwise, the pressure becomes high during operation with the risk of system breakage. 8.6.1 Refrigerant diagram i‐SHWAK V4 06, 08 COMPRESSOR C ... -

Page 34: Shutdowns For Long Periods
Inverter air/water chillers and heat pumps with floor‐standing and remote condensing units i‐SHWAK V4 11 SHUTDOWNS FOR LONG PERIODS The types of shutdown depend on the weather of the site where the unit is installed and on the period of the stop. The antifreeze system, if it’s installed, stay on work also with the on‐board control unit in “OFF” position. If the time of stop is long and the temperature is low, we recommend you to drain the hydraulic circuits or use a mixture of water and glycol. Discharge the hydraulic circuits and shutdown the unit following the below steps: Turn off the units from control panel (displayed “OFF”). Close the water faucet (tap). Place the general differential QF switch in “OFF” state (if it is installed upstream of the system). If the indoor unit is installed in areas of the building subject to low temperatures (attics, basements, etc.) and the temperature drops below 0°C there is serious danger of frost: provide please a mixture of water and glycol in the plant system, otherwise drain the water system and the hydraulic circuits of the heat pump. If it is necessary to add glycol to the hydraulic circuit of the plant, provide a T‐fitting with tap downstream of the non‐return valve on the charging/topping up pipe (see Paragraph 8.5), in order to adapt the glycol concentration. WARNING: even the transient operation, with water temperatures below +5°C is not guaranteed on the basis of the limits set out in Paragraph 21.4 . Before you turn the unit on after a long off period, make sure that the temperature of the mixture of water and glycol is higher than or at least equal to +5°C. 12 MAINTENANCE AND PERIODIC CHECKS WARNING: All the operations described in this chapter HAVE TO BE CARRIED OUT BY TRAINED STAFF ONLY. Before any operation or before acceding to the inner components of the unit, be sure that the power supply is not connected. The compressor’s heads and discharge piping are usually at high temperature levels. Be very careful when operating in their surroundings. Aluminium coil fins are very sharp and can cause serious wounds. Be very careful when operating near them. After servicing operations, re‐ install the cover panels, and fix them by means of screws. The refrigerant circuits must not be filled with refrigerant gas other than that indicated on the nameplate. The use of a different refrigerant can cause severe damage to the compressor. It is forbidden to use refrigerant oils other than those specified in this manual. The use of different oil can cause serious damage to the compressor. The top part and discharge pipes of the compressor operate at high temperatures. Be sure to let the unit to become cool before beginning any maintenance work. Be careful when working near the condensing coils. ... -

Page 45: Reading Of The Indoor Unit Manometers
Inverter air/water chillers and heat pumps with floor‐standing and remote condensing units i‐SHWAK V4 17 READING OF THE INDOOR UNIT MANOMETERS Each indoor unit is equipped with two manometers. The difference between the manometers (1 and 2) reading can be used as approximate value for verifying the water flow rate/pressure head when the unit works on the plant. To the difference of manometers value you should subtract the pressure drop of the 3‐way valve for getting an approximate value of the available pressure head of the plant. The characteristic curve corresponding to the Head pressure versus Water flow rate of the three‐ way diverter valve, whose values should be deducted at the manometry for verifying with sufficient accuracy the available static pressure of the plant system at the nominal operating points marked in the curves of Chapter 16. For certainty raisons, it is recommended to remove 5% from the obtained values. 18 DHW INSTANTANEOUS PREPARER Here below are indicated the operating regions of the instantaneous DHW preparer versus the temperature of the primary circuit (DHW temperature of technic side) and the water flow rate of the secondary circuit (DHW withdrawal rate), for different values of the set temperature of domestic hot water (T"_Set_DHW). The region of operation corresponding only to the optional electric heater is indicated with red dashed lines. WARNING: It is necessary to install on the DHW line between the instantaneous preparer and the mixers of domestic hot water, an anti‐scald thermostatic valve calibrated at 45°C. Otherwise there is a serious risk of burning and severe scalding. WARNING: ... -

Page 50: Hot Water Production (Winter Operation)
Inverter air/water chillers and heat pumps with floor‐standing and remote condensing units i‐SHWAK V4 21.3 Hot water production (winter operation) Once the system is working at the right temperature, the inlet hot water temperature should not to be lower than 25°C; the lowest values that are not related to transitional or start‐up stages may cause incorrect working operation to the system with the possible breakdown of the compressor. The maximum outlet water temperature should not exceed 58°C. At this temperature, the power consumption and the performances in terms of COP are enhanced when the outdoor temperature is higher than 5°C, even if the unit is still able to work up to the limit reported in the envelope. For higher temperatures than those pointed out, especially if have a concomitant with the reduction of the water flow rate, it may cause abnormalities to the normal operating of the unit, or the safety devices act in critical cases. 21.4 Ambient air temperature The ... -
