NOTE: All the option will be supplied and mounted in the unit, except the water filter, water isolation valves, rubber

antivibration mounts, remote controller and air intake plenum supplied to mount in the moment of installation.

MAIN ON/OFF SWITCH

Located at the electrical box of the unit.

FLOW SWITCH

 (included on Hydraulic and Hydronic versions)

The flow switch stops the unit if water flow is lower than the minimum.

WATER FILTER

  (included on Hydraulic and Hydronic versions)

The water filter must be fitted in the water inlet of the unit, it protects the unit against particles (greater than 1 mm) getting inside the water circuit,

and prevents the water interchanger gets dirty.

EVAPORATOR ANTI FREEZE PROTECTION

The evaporator anti freeze heater prevents the water exchange from low temperatures.

CONDENSER PROTECTION GUARDS

The condenser coil protection grill prevents light damage to the coil when shipping and when installed. It cannot protect against very heavy impacts.

THERMOSTATIC HOT GAS INJECTION

Supplies hot gas which is injected into the evaporator gas to increase the suction pressure if the chilled water temperature falls to low. It can be

used to allow the unit to operate at reduced capacity, if the water temperature falls below the set point (5ºC). It is controlled via the microprocessor

controller ON at (5ºC) and OFF (6ºC) for example. This option is NOT available for units selected with low water temperature option.

THREE PHASE PROTECTION

Located at the electrical box of the unit, it assures that unit will not begin operation if connection phases of compressor are not correct. Should

this occur, then just switch two phase connections.

HP AND LP REFRIGERANT GAUGES

Visualize the high and low pressures of the refrigerant circuit.

EPOXY COATED ALUMINIUM FIN COILS TREATED

Special protection of the aluminium condenser coil fins, to give improved protection from aggressive external environmental conditions.

REMOTE DISPLAY

Controls and visualizes the unit's operating, it may be installed until 50 m from the unit.

HEATING LOW AMBIENT KIT (-15ºC)

The reverse unit can operate in heating mode down to an ambient temperature of -15ºC (standard unit just can operate down to -10ºC).

LOW AMBIENT KIT (-15ºC)

The cooling only unit can operate down to an ambient temperature of -15ºC (standard unit just can operate down to 0ºC).

IN/OUT ISOLATING VALVES

To fit at inlet and water outlet of the unit. Isolating the unit from water circuit, so service and maintenance of the unit will be easier.

For units EAC 1003-1303 SKHN this option includes another valve in order to isolate the buffer tank.

ANTI-VIBRATION MOUNTS RUBBER

To install under the unit, to avoid transmission of vibrations, to the floor where unit is installed, while unit is operating.

 X  Option element

(1) Water tank included

(2) Only versions FP1/FP2

(3) Only for heat pumps units.

(4) Not available for units EAC 0251 FP2 to 0812 FP2.

(5) Standard for models: EAR 0472 to 1303 /EAC 1003 to 1303.

(6) For models 0251 to 1303.

     With twin pumps, water filter has to be mounted

     outside the unit (1003 to 1303 models)

(7) Not available for units EAC 0472 to 0812.
