PRE-INSTALLATIONPrior to install the equipment, make sure of the following points:• Leave enough space for access to air supply, water section, power supply and condensed outlet.• The water section must have the correspondent valves.• Easy extraction of the air filter.• Easy access to lateral panel for easy accessibility to all services of the unit.• Unit must be mounted with antivibration.• The electrical section must be done following legal normative• Check that the tension is the same as installation place.• Keep in mind power supply for maximum consumption for each unit.• Check water quality, across analysis according to local normative. If quality of water is not good, it may be necessary to install
a device to decalcify.• Corrosion resistance of plates exchanger: The resistance guide below is an attempt of give a picture of the corrosion resistance
of the stainless steel of the type AISI 316 and pure copper in the water, to a number of important chemical factors. The actualcorrosion is however a very complex process influenced by many factors in combination. This table is therefore a considerablesimplification and should not be overvalued.
• Keep in mind water inlet temperature to the unit. If this temperature is below 15ºC for cooling only units (FWCK), you will needto install a water regulation pressostatic valve (as an option element) to keep condensation temperature value between 40and 45ºC.
Flow switch can be asked as an option. It stops the unit if there no water flow or if the water flow is below minimum value.• Be sure that air flow is according to the ducts installation.
Explanations:+ Good resistance under normal conditions.0 Corrosion problems can occur especially when the factors are valued as 0. - Use is not recommended
INSTALLATION
It is very important that the unit works with water flows between maximum and minimum values according to thetables. You have to calculate water pump and install regulation valve if they are needed, in order to be sure thatthe unit works with water flow values indicated in the tables. Specially for heat pump units FWHK in heating mode,if the unit works with water flow below specified values, the unit can be seriously damaged, water exchanger canbe frozen.
12
• Make sure that water connections are correct, water inlet (upper side), water outlet (down side).
INSTALLATION• All installation must be carried out by qualified personnel.
Air flow:
• All models include three fan speed motor fan, except for FWCK/FWHK 22 models. The transmission for this model isdone through pulleys and belts.
• Make the motor fan connections for the fan speed required and adjust the pulley for FWCK/FWHK 22 models in orderto adequate the air flow needed for the installation.
• Use the flexible tube connected to the drip tray as a drainage tube. Cause a siphon with this tube inorder to avoid the inlet of scents from the installation to the unit.Install a siphon from the drainage tube of the drip tray with a difference in height of 80 mm to prevent fromnot evacuating due to the negative pressure created by the fans. The pipe will slope down 2% to make iteasier for the condensates to drain off.
Lennox offers this element as an option.• Install cut off valves at inlet and outlet water connections, because of in case of repairs, the hydraulic circuit can be independent.
• After supply the power to the unit and connect inlet/outlet water:
The unit can be work properly until next maintenance revision.

OPERATIONOn a system operated with refrigerant R-407C, during the evaporation phase at constant pressure the temperature increases;and during the condensation phase at constant pressure the temperature decreases a certain value. Consequently, the terms“evaporation temperature” and “condensation temperature” should be redefined.The refrigerant R-407C is a mixture of other three refrigerants that behave as pure compounds. This fact makes that theoperations of installation, service and maintenance must be special, for the next operations:
COMPRESSOR OILWith HFC refrigerants as R-407C, the compressors incorporate ester oil instead of mineral oil used for R22 (HCFC).
LEAKSIf a leak takes place in the system that has produced an important evacuation of the refrigerant charge, instead of rechargingthe system, it is convenient to eliminate the whole charge completely, the system must be evacuated and charged again or tointroduce the charge according to an specified value.
REFRIGERANT CHARGINGTo maintain the mixture composition, the refrigerant must be charged always in liquid phase. For what it is necessary to havespecial caution when it is little quantity of refrigerant in the bottle.
VACUUM OF THE SYSTEM (When the unit has loosed refrigerant charge).Vacuum must be done until 0.225 mm Hg, since the compressor oil high hygroscopic degree can cause corrosion in somemetallic materials.
This unit can only work with R-407C Refrigerant.Do not use another type of refrigerant.

INSTALLATION• The electrical heater should be installed into the impulsion fan of the unit.• Fix the electrical heater to the unit with the screws (see the figure above).• Take out the knock out, and take the electrical supply of the electrical heater to the electrical box of the unit. There is a differentpower supply for electrical heater (see page 4).
PRESOSTATIC VALVE (only for units FWCK)This option is supplied loose.If water inlet temperature is below 15ºC use a pressostatic valve to keep adequate condensation temperature levels (40º to45ºC).The maximum inlet water temperature with this option is 35ºC.
PRESSOSTATIC VALVES REGULATION• Connect a manometer of high pressure (30 bar) in the refrigerant circuit.• Turn over the spindle in the head of the valve (turn right: the valve is opened; turn left: the valve is closed) regulating the water
flow which enters into the unit.• You must leave the unit working at least 10 minutes and see the indication of the manometer. If the condensation pressure
temperature is approximately 45ºC, the valve is correctly regulated. If not, restart the regulation as described before.
INSTALLATION• Replace the outlet pipe of the plate exchanger inside the unit for a pressostatic valve.• Keep in mind the row direction indicated in the valve.• Connect the capillary tube of the valve to the plug of high pressure in the pipe of the unit.
OPERATIONThe pressostatic valve keeps the condensation pressure values regulating the inlet water flow in the condenser.When the condensation pressure is up, the valve will be opened, and more water is entered. And when the pressure is lowthe valve will be closed.
