PHASE SEQUENCER
The phase sequencer is located in the electrical box in the outdoor section, thus assuring that the unit will not
begin operation while the phase connection of the compressor is not correct. Should this occur, then just switch
two phase connections.
ON/OFF CONDENSATION PRESSURE CONTROL
The condensation pressure control consists of one or two pressure switches, which starts and stops the outdoor
fan, regulating the condensation temperature; thus the unit will be able to operate in the cooling cycle when the
outdoor temperature is below 19ºC, (Until 0ºC).
CRANKCASE HEATER (COOLING-ONLY UNITS)
The purpose of the heater is to keep the oil in the compressor at the correct temperature while the compressor is
stopped so that it can be properly lubricated when starts again.
When the unit is operating at low outdoor temperatures (below 19ºC), it is advisable to fit a crankcase heater.
HOT WATER COIL
It is based on a refrigerating coil made of copper tubing
with aluminum swirl fins with water inlet and outlet
connections.
It is supplied mounted inside the unit as picture shows.

A HEATING COIL FROZEN DUE TO LOW AMBIENT CONDITIONS IS NOT COVERED BY THE WARRANTY.
PROTECTION AGAINST FREEZING:
• Use glycol water. GLYCOL IS THE ONLY EFFECTIVE PROTECTION AGAINST FREEZING.
• This kit includes a security thermostat with a probe located inside the hot water coil. When the temperature is
below 4ºC, the unit will stop in order to protect hot water coil and to prevent unit working with very low evaporating
temperatures.
Two wires between indoor and outdoor unit have to be added with this option.
Security thermostat working mode:
- Electrical boxes with Climatic 10 controller: The security stop valve is 4ºC. When the valve is more than 4ºC +
thermostat differential, you can reset the unit pressing "resume" button in the Climatic 10 terminal.
- Electrical boxes with VFC: The security stop valve is 4ºC too. When the valve is more than 4ºC + thermostat
differential, the unit will reset automatically after 5 min of timer.
• Drain the installation. You must ensure that the manual or automatic air vents have been installed on all high
points in the system. In order to drain the system check that all the drain cocks have been installed on all low
points of the system.
