GeneralThe SPCA-HSB series air-cooled water heat pump consists of 9models covering cooling capacities from 5,8 up to 31,8kW andheating capacities from 6,9kW up to 37,3kW.It is the end result of a thorough study, and accurate design byexperienced Interklima research and development teams, todevelop a small size heat pump series with compact shape, highperformance, and reliability of the highest quality standards.This series meets the highest levels of aesthetic and technicalrequirements using the latest technological innovations includingenvironmentally friendly R407c refrigerant that is Chlorine-freeand has zero ozone depletion potential. SPCA-HSB units aretherefore ideal for installation in urban environments due to theirelegant design, selected materials and low operating sound levels.
CasingAll units use metal parts fabricated from heavy gauge galvanizedsteel sheets, formed to ensure maximum rigidity that guaranteesand preserves the units operation during the years. After fabricationmetal parts are degreased, phosphatised, and electrostaticallypowder coated with an epoxy-polyester RAL 9002 coating of athickness of 60-70 Ì. This fully automatic process ensuressuperior corrosion resistance against the most aggressive ambientconditions. The treatment can successfully withstand a salt spraytest of 500 hours, according to ASTM B-117.All components are assembled together using bolts thus avoidingthe need for welding which may harm the galvanization of thesteel, and ensures that the whole assembly can fully withstandadverse weather conditions.The compact footprint of the unit arises from detailed study anddesign by our engineering teams and results in a machine, whichfits easily in restricted areas and is simple and easy to install andmaintain, and has been designed with special fittings for easytransport and lifting.Removable panels with special locks are used to permit accessonly to authorized personnel to internal components of the unit forinspection and maintenance.
CompressorAll units use low-noise, maintenance free, Hermetic Scrollcompressor with low vibration levels, specially optimized for usewith R407c refrigerant, selected from world class suppliers.They are equipped with a crankcase electrical heater for the oil,and are internally protected against potential overloading orelectrical spikes.The compressors are mounted on special antivibration rubbermounts to eliminate vibration from the unit’s operation.
Hydraulic kitAll units are equipped, as standard, with a complete hydraulic kitcomprising of a circulating pump, buffer and expansion tank,automatic fill and make up water valve with manometer, safetyvalve, airvent, water filter, differential water pressure switch, andevacuation valve.
Air heat exchanger All unit air heat exchangers are manufactured from high qualityinner grooved seamless copper tubes according to ASTM B-280,having an outside diameter of 9,52 mm (3/8"). The fins aremanufactured from aluminium and form the secondary extendedheat transfer surface. The fins are continuous across the heatexchanger and are fabricated in high precision dedicated presslines. The fin surface is waffle formed, so as to increase the finrigidity, and have special louvers that help increase heat transfer.The combination of internally grooved Copper-tubing and louveredfins has resulted in a heat transfer performance 30% superior tothat of a conventional coil for this particular application. Theassembly of the finned pack is achieved by mechanical expansionof the tubes in such a way as to form a perfect mechanical bondwith the fins. For this purpose, the fin holes have a peripheralextrusion (collar) of adjustable height. This extrusion serves todefine the distance between fins (and consequently the total heattransfer surface) and to ensure perfect contact of the fins to thetubes.Alternative fin materials are available upon request such as epoxy- coated aluminium or copper for applications in especiallyaggressive environments.
Water heat exchangerAll units are equiped with a water - refrigerant Plate HeatExchanger, selected from world class manufacturers.It is made of stainless steel plates (AISI 3161.4401) speciallyformed to achieved a large heat transfer surface and assembledby means of an automatic brazing proccess, under vaccum.
Air heat exchanger fansAll unit fans are of the axial type, single phase, 6 poles, internallyprotected against potential overheating silent and suitable foroutdoor installation. Due to the sophisticated aerodynamic designof the blades and inlet cones, as well as the perfect static anddynamic balancing, their operation is completely vibration-free. Thefan-motor assembly has a protective grid against accidentalcontact with moving parts, which is designed according to ISOregulations. Fan motors are of the external rotor type,aerodynamically shaped so as not to interfere with the airflow, and

The SPCA-HSB unit should be installed in a location that meets thefollowing requirements:1. The foundation is strong enough to support the weight of the unit,
and the floor is flat to prevent vibration and noise generation.2. The space around the unit is adequate for servicing and the
minimum space air inlet and air outlet is available. If several unitsare being installed side by side in parallel, the minimum servicespace between them must be taken into account
3. There is no danger of fire due to leakage of inflammable gas.4. Ensure that water cannot cause any damage to the location in
case it drips out the unit.5. Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction.Frontal wind willdisturb the operation of the unit.If necessary, use a windscreento block the wind.
6. In heavy snowfall areas, select an installation site where snowwill not affect operation of the unit.
7. Make sure that the unit mounting base can be fixed directly onconcrete.
8. In order to avoid the transmission of vibration from the operatingunit to its carrying structure, the use of antivibration material toinstall under the supports of the unit is recommended. It issuggested to install a rubber pad between the points of supportand the base of the unit, or spring antivibration mounts undereach point of support of the unit.

ñ All units are equipped with a complete hydraulic kit as shownthe figure below
ñ All field conections must be carried out by a licensed technicianand must comply with the applicable local and national codes
ñ Evaporator water connections should be made in accordancewith the unit outlook respecting the water inlet – and outlets
ñ Connect a fresh water line to the water make up connection.The units are equipped with automatic make up valve tofacilitate water make up.
ñ It is advisable to connect flexible water inlet and outlet tubesto avoid vibration transmission
ñ The unit is operating in closed circuit. Avoid frequentunessasary water evacuation.
ñ It is essential to install a thermometer in the water inlet/ outlet
pipe to check temperatures.ñ Provide heat insulation with suitable vapour barrier around the
chilled water piping to prevent condensation and capacity loss.ñ Provide drain connections at all low points of the system to
permit complete drainage for maintenance and/ or shutdownñ Air vents should be provided at all high points in the system
located where they are easily accessible for servicing. Thewater inlet pipe is specially designed to obtain a complete airpurge of the evaporator.
ñ To avoid frequent on / off operation of the compressor, aminimum water volume is required in the system (table 10.4)
ñ To assure proper operation of the unit, the water qualitythrough the evaporator must be within the specified limits(table10.4).

10.6.2 Displays10.6.2.1 DisplayNormal display shows:
ñ Regulation temperature in tenths of degreescelsius with a decimal point, or in degreesfahrenheit without a decimal point.
ñ The alarm code, if at least one alarm is active. Ifmultiple alarms are active, the one with greaterpriority will be displayed, according to the Tableof Alarms.
ñ If temperature control is not analogue anddepends on the status of a digital input (ST1 orST2 configured as digital inputs), the “On” or“Off” label will be displayed, depending onwhether temperature control is active or not.
ñ When in menu mode, the display depends on thecurrent position; labels and codes are used tohelp the user identify the current function.
ñ Decimal point: when displaying hours of operation,indicates that the value must be multiplied x 100.
