INTRODUCTION TO THE SIRAC DOMESTIC HOT WATER HEAT PUMPLSQ015RC - 2012

The SIRAC Domestic Hot Water Heat pump is a product that is specifically designed to heat water.It provides hot water at a maximum efficiency in extreme operating conditions. The unit can operate withexisting high or low pressure geysers. The unit is essentially plug n play with minimal plumbing and power

connections.

General Specification:

Model LSQ015RCCapacity 4.7 kWKW input 1.3 kWCOP 3.6 (@ 15C WB Ambient)Running Current 6.2 ampRefrigerant R417a

Maximum water temperature 60 cPower supply 230/50/1Compressor type RotaryWeight 70 kgDimensions 900 x 750 x 285 (mm L x H xW)

Features:

Large evaporator coilThis increases the evaporator pressure at low ambient temperatures. Specifically designed to operate with refrigerant R417a. Thisrefrigerant has a much lower discharge pressure and temperature than R410a and R407c. Reduced pressure and temperature

prolongs the operating life of the compressor and provides a stable performance.The large evaporator coil gives increased heating efficiency at low ambient temperatures and high altitude conditions while at thesame time reducing the energy consumption.

Two speed Evaporator fansThe fan runs on high speed at low ambient temperature conditions and low speed at high ambient temperatures. This setting isprogrammable on the microprocessor. This provides a stable and efficient refrigeration cycle at the varying operating conditions.

Matsushita (Panasonic) Rotary Compressor.This compressor is recognised as the industry standard for performance, reliability and efficiency.

Brass housing energy efficient Circulator Pump.Ceramic shaft and bearings, carbon thrust, stainless steel water jacket, Composite impellor and EPDM gaskets.IP44 enclosure. With brass easy to remove swivel unions.

Separate anechoic acoustically lined compartment for the compressor.Acoustic sound attenuation makes the unit suitable for use in noise sensitive areasSeparate sound insulated compressor enclosure makes sure that the compressor sound is not transmitted through the fan housing.

Dual Temperature controller.Manages the two speed fan, provides close temperature control with diagnostic tools and error messages.Backlit Display displaying:Evaporator Temperature.Discharge Temperature.Ambient Temperature.Inlet Water temperature.Outlet Water Temperature.

Three programmable timer settings per dayError signal.

Plastic Drain connection.Allows the condensate to be piped away from the unit.

Internal flow control ValveThe SIRAC Domestic Heat Pump is factory fitted with a Flow Control Device. This control device varies the water flow through theheat exchanger to maintain a constant gas condensing pressure. The gas pressure is directly related to the gas condensingtemperature. Controlling this pressure at a specific set point insures that the water leaving temperature is maintained >50 deg. c.This allows the hot water to be connected directly to the geyser hot water outlet pipe. No water connections are made to theactual geyser. This prevents temperature mixing in the geyser.

Internal circulating pump

Reduces on site labour and additional fittings.

Automatic air bleed factory installedProtects the pump against operating with an air lock. The heat pump can be installed above the geyser. Speeds up commissioningtime.

Large electrical panel.Easy connection terminals and good access to the electrical components. Separate electrical panel cover.

Attractive strong protective evaporator grille that reduces vibration and coil damage.

Heavy Gauge Epoxy Coated Galvanized Steel CasingRemovable panels allow good service access to all components

Separate easy access compartment for the circulating pump, Flow Control Valve and Air Release Valve.

Ultra thin SIRAC Proprietary hot water sensor provided as standard.This sensor can be installed in the existing geyser thermostat pocket while still retaining the standard geyser thermostat
