During installation operations, keep gas and liquid pipes covered, in order to prevent humidity
and dirt, get into them.
Take special concern about refrigerant pipes are isolated.
Avoid collapse on pipe lines installation.
1º Remove the nitrogen gas, through the high and low 1/4 service ports locate inside, from both indoor and outdoor
units.
2ª Remove the covers from connecting lines.
3ª Braze the piping connection lines. Refer to installation manual to select the diameter of the lines.
(When brazing refrigerant pipes, is necessary to supply nitrogen gas through the service ports into the pipes to
remove the air)
4º Leak test:
- Add nitrogen gas and check 5 kg/cm

pressure has been reached, and verify there are not leaks in the circuit or
brazing, applying soapy water on pipes, because the leaks cause soapy water to form bubbles.
To detect small leaks proceed as follow:
Add nitrogen gas and check 32 kg/cm2 pressure has been reached, there is not leak if pressure remains the same
at least during 24 hours and final pressure is not less than 10% from the initial pressure.
5º Be sure gas line is isolated.
6º Vacuuming.
Remove the nitrogen gas, connect the gauge manifold and vacuum pump to both liquid and gas lines, fully open
the valve of the gauge manifold and switch on the vacuum pump. Check to make sure the gauge shows a pressure
level of -750mm Hg, after a level of -750mm Hg is reached, keep on the vacuum pump at least during an hour.
7º Refrigerant charge:
- Refer to installation manual to verify amount and type of refrigerant which must be charged, and the total
amount to be added must be calculated considering the refrigerant charge of the unit, and also the length and sizes
of the refrigerant piping.
- Disconnect the vacuum pump and connect to the refrigerant-charging cylinder. Open the charging cylinder
and purge the air from the hose at the gauge manifold.
- Set up the amount of additional refrigerant on the weighing scale, open the high pressure (liquid) and low
pressure side (suction) of the gauge valve to start the process of refrigerant from outdoor unit. If the total amount
of refrigerant charge has not been reached, because balance pressure, turn off the high side of the gauge manifold,
turn on the unit, and add slowly through low side of the gauge the remain amount of the refrigerant charge needed.
(With R-407C refrigerant, the charging cylinder must be on horizontal position and it is important to charge

- The charge should be carried out in the Liquid Phase.
- Always use scales to weight-in charge- Use the Leak Detector exclusive for R-407C Refrigerant.
- Do not use mineral oil, only synthetic oil to ream, expand or make connections.
- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, filings,
burrs, etc.).
- When there is a leak, gather what is left of the charge, create a vacuum in the unit and completely
recharge with new R-407C Refrigerant.
- Brazing should always be carried out in a nitrogen atmosphere.
- Reamers should always be well sharpened.

2.- INSTALLATION
CHARGE OF REFRIGERANT FOR THE SET:
EXAMPLE:
To install a KVHK 38E + LEHK 38E set, with a 22m refrigerant line length between outdoor and indoor unit, then
the refrigerant charge must be calculated as follow:
1º Type of refrigerant R-22 or R-407C, in this case, R-407C .
2º The TABLE 4 shows, that for 22m of line length between indoor unit and outdoor unit, the line sizes are, liquid
7/8", and gas 1-5/8".
3º TABLE 4 shows, for line sizes of 7/8"- 1-5/8", the charge per meter line is: 327 gr/m.
4º TABLE 2 shows, charge of refrigerant for the set with 0m of line length is 10.500gr.
5º To determine the charge of the set:
Add charge of the refrigerant lines + charge of refrigerant indoor unit and outdoor unit.
Total charge for the set: (327 gr/m) x 22m + 10.500 gr = 17.694 gr

LOCATION
The unit can be installed outside. If it is installed, air entry and exit ducts should be fitted. The outdoor unit should
be assembled on bases previously made and stood on absorbent and antivibrating material to avoid the vibrations
being transmitted to the structure of the building.

3.1.- PRELIMINARY CHECKS

- On the heat pump units, the compressor has a single phase electric heating element to assure a separation
between the Refrigerant and the oil in the housing. This heater is activated when the compressor is off and stops
working when the compressor is on.
About eight hours before start up or after a long shutdown period, voltage should be supplied to the unit so that
this heater will be activated.
- To start the unit, follow the instructions given in the Control Panel Manual supplied with the unit
(requesting operation in any of the modes, cooling, heating, or automatic).
After a time lapse, the unit will start.
- With unit operating, check that the fans are turning freely and in the proper direction.
- Check compressor oil level, sight glass included (on the sides of the compressor, the level should be between
1/4 and 3/4 in the sight glass, while during operation the level should be between 3/4 and full).
- Connect high and low pressure gauges and check that operating pressure values are normal.
- Measure electrical consumption for the unit and check that it is near what is indicated on the Rating Plate.
- Check the electrical consumption of the compressor and the fans with what is specified in the physical data sheets.
- In the case of a Heat Pump unit, make a cycle change on the Control Panel checking that the 4-way valves make
the change correctly. Check the pressure values in the new cycle.
- Remember the low pressure switch is reset automatically and the high pressure switch is reset electronically.
- Check that pressure switches stop the unit:
FOR THE COOLING CYCLE UNIT:
Stop the outdoor fan by disconnecting it. The high pressure should rise and the high pressure switch should stop
the compressor at 27.5 kg/cm . Reconnect the fan and electrically reset the pressure switch by pressing the
RESUME button on the Control Panel for 5 seconds for standard unit version, and press "OFF" for VFC version
units and wait for the anti-cycle time (5 minutes), afterwards, the unit will start-up again.
Stop the indoor fan by disconnecting it. The low pressure should drop and the unit should stop when the pressure
gauge reaches 1 kg/cm . The unit will start up again when the pressure rises and the pressure gauge indicates
2 kg/cm . Once this has been carried out, stop the unit and reconnect the fan.
- Start the unit again and when everything is operating normally, take a reading of all the data and fill out the
Commissioning Sheet.
Scroll type compressors only compress in one direction of the rotation. Single phase models are always
started up in the proper direction; however, the three phase models, turn in either direction depending on
the order of the power supply phases. Therefore, it is essential that the phase connection for scroll-type
three-phase compressors be carried out correctly (the correct direction of rotation can be checked when
the pressure on the suction side decreases and the pressure on the discharge side increases when the
compressor is activated). If the connection is wrong, the rotation will be reversed causing a high noise
level and a reduction in the amount of current consumed. If this occurs, the compressors internal protection
system will kick in shutting down the unit. The solution is to disconnect, switch the wires between two of
the phases and connect again).
REMEMBER THAT THE COMPRESSOR IS A SCROLL TYPE COMPRESSOR:

-GENERAL STATE OF THE CASING :
Furniture, paint, deterioration due to bumps, rust spots, leveling and supporting, state of the shock absorbers,
if installed, screwed panels, etc.
- ELECTRICAL CONNECTIONS :
State of hoses, tightness of screws, grounding, current draw of the compressor and fans and checking that the
unit is receiving the correct voltage.
- COOLING CIRCUIT :
Check that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe
insulation, that the state of the batteries is correct and that there are no chips or clogs
retained by the air flow, etc.
- COMPRESSOR :
Inspect the oil level, if sight glass is present.
Inspect the state of the silent block fixtures.
- DRAINS :
Check that water drains correctly and that the drain trays are clean.
- FANS :
Check that fans turn freely and in the correct direction without excessive noises.
- CONTROL :
Check Set Points and normal operation.

If some component in the cooling circuit must be replaced, follow these recommendations:
- Always use original replacement parts.
- Remove the entire refrigerant charge from the unit through the schrader valves located in the outdoor section.
Create a slight vacuum as a safety measure.
- Regulation prohibits the release on the refrigerant into the atmosphere.
- If cuts must be made in the pipe work, use pipe cutters. Do not use saws or any other tools that produce filings.
- All brazing must be carried out in a nitrogen atmosphere to prevent corrosion from forming.
- Use silver alloy brazing rod.
- Take special care that the flame from the torch is aimed in the opposite direction from the component to be
welded and is covered with a wet rag in order to avoid overheating.
- Take very special care if 4-way check valves are to be replaced since these have internal components that
are very heat-sensitive such as plastic, teflon, etc.
- If a compressor must be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove
the securing screws and replace the old compressor with the new one. Check that the new compressor has the
correct oil charge, screw it to the base and connect the lines and electrical connections.
- Carry out the vacuum above and below through the schrader valves of the outdoor unit until -750 mm Hg is
reached.
Once this level of vacuum has been reached, keep the pump in operation for at least one hour. DO NOT USE
THE COMPRESSOR AS A VACUUM PUMP.
- Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are
no leaks.
IMPORTANT
MAKE SURE THAT THE UNIT IS COMPLETELY DISCONNECTED FROM THE POWER SUPPLY
WHEN CARRYING OUT ANY TYPE OF WORK ON THE MACHINE
If R-407C Refrigerant is used in the unit, the following precautions characteristic of this gas should
be taken:
- The Vacuum Pump must have a Check Valve or Solenoid Valve.
- Pressure Gauges and Hoses for the exclusive use with R-407C Refrigerant should be used.
- The charge should be carried out in the Liquid Phase.
- Always use scales to weight-in charge.
- Use the Leak Detector exclusive for R-407C Refrigerant.
- Do not use mineral oil, only synthetic oil to ream, expand or make connections.
- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, filings,
burrs, etc.).
- When there is a leak, gather what is left of the charge, create a vacuum in the unit and completely
recharge with new R-407C Refrigerant.
- Brazing should always be carried out in a nitrogen atmosphere.
- Reamers should always be well sharpened.
