OPERATIONAL LIMITS
CONFIGURATION EXAMPLES
TRANSPORTATION AND RECEIVING THE MACHINES ON SITE
The unit must be lifted and transported using a forklift, pallet jack, winch hoist or through a rope hoist system. If the unit is not to be installed immediately after arrival on site, it should be stored in its original packaging in a dry, enclosed area, preferably heated during the winter months.

For exact values referring to the dimensions shown in the figure, refer to the table below and, in any case, to the drawings provided with the order confirmation. During installation, observe the spaces required for planned maintenance (and if special, if necessary) indicated in the order confirmation or in the table below, referring to the standard models.
UNIT POSITIONING
PLENUMS AND PLINTHS (ACCESSORY)
The dimensions of the plenum and plinths can be found in the order confirmation or in the following tables (standard models). The plenum and duct sections at the top of the unit are mounted using the four supplied brackets, which must be mounted on the top frame of the unit.

COOLED WATER COIL CONNECTION
These systems - in the event of a sudden drop in cooling capacity by some users - can lead to pressure peaks in the circuit, due to the modulation time of the pumps, thus to an increase in the water flow rate inside the units. To address the problems associated with balancing valves, Systemair has developed an independent pressurized water flow control system that makes it possible to limit the maximum flow rate of the system even when faced with high water pressure in the circuit. This accessory includes the installation of a measuring device to check the instantaneous water flow of the system.
Accurate and reliable adjustment of environmental energy loads, avoiding annoying over-adjustments due to the sudden increase in water flow rate. Savings in system commissioning time, due to the extreme ease of setting the water flow rate, resulting in savings in system start-up and management costs.

WATER CONDENSER CONNECTION (ACCESSORY)
If the water supply comes from a well or river, two filters with suitable characteristics for the type of water must be installed in parallel (one as a back-up for the other) to prevent the condenser from clogging with impurities in the water. The positions of the water inlet and outlet connections are indicated in the figure below. The maximum pressure of the water supply to the water-cooled condensers is 16 bar (1.6 MPa), the minimum pressure is 1 bar (1 MPa).
The maximum pressure difference between the inlet and outlet pipes is 2.5 bar (250 kPa), since the return spring would not be able to close the water flow at larger pressure differences. In case of larger pressure differences, it will be necessary to install a reducing valve before the valve.
CONNECTION OF THE INTERNAL SUBMERGED ELECTRODE HUMIDIFIER (ACCESSORY)
The correct operation of the humidifier mainly depends on the chemical/physical properties of the water supply. There is no reliable relationship between water hardness and conductivity and between cylinder conductivity and production!. If the characteristics of the humidifier supply water do not match the characteristics of the special cylinders, alternative systems that cannot be integrated into the unit, such as resistance or ultrasonic humidifiers, must be evaluated.
PRECAUTIONS
COOLING CIRCUIT ACCESSORIES
During the winter months, with very low temperatures, the refrigerant can build up in the condenser, which can cause a low pressure problem when starting the compressor. The kit for use at very low outdoor temperatures consists of a larger liquid tank that can hold a larger amount of refrigerant, a check valve on the liquid line to prevent migration of the refrigerant into the condenser and a check valve on the supply line to prevent migration of the liquid refrigerant into the condenser. prevent compressor. During the winter, with very low temperatures, the installed components prevent the liquid refrigerant from migrating to the condenser.
However, the coolant will remain in the fluid receiver to the extent to prevent low pressure problems during startup. Instead, the inlet check valve prevents fluid from returning to the compressor during the summer, which could cause damage at start-up and/or prevent smooth operation due to condensation after the compressor shuts down, resulting in a high-pressure block.
ROUTING OF THE COOLING CIRCUIT PIPES
COOLING CIRCUIT SIZING
For lines with descending vertical height difference of more than 8 m, a 30% larger air condenser must be provided. The recommended diameters for the supply, fluid and inlet lines according to standard model size (expressed by the number sequence of coding) are detailed in the order confirmation or in the following table.
COOLING CIRCUIT INSTALLATION
Do not leave the circuit outside for a long time to prevent excessive moisture formation. To prevent copper dust or lead from entering the system, the pipes should be cut using a pipe cutter and not a hacksaw. When performing kneading while introducing nitrogen into the tube, the nitrogen should be adjusted with a pressure reducing valve to 0.2 Bar (20 kPa) (just enough to feel on the skin).
After the cooling circuit is completed, it is recommended to check the solder joints and connections with nitrogen pressure. If the pressure cannot reach this reading, there is a leak in the circuit.

The wiring diagram suggests dimension values for the power line and the appropriate protective devices. They must be properly sized to handle the maximum load in amps indicated on the wiring diagram and on the data plate located inside the electrical compartment of the unit itself. The thermal-magnetic circuit breaker, the installation of which is the customer's responsibility, is essential to ensure overcurrent protection on the supply line (Art.
To avoid operating problems with the microprocessor controls, it is imperative that no other consumers (pumps, condensers, etc.), even those that are part of the same system, are connected downstream of the air conditioner's main switch, unless explicit permission is granted by Systemair. If this condition cannot be met, it is necessary to connect suppressors (R + C) in parallel to the coils of the relays of such loads.

Position of air filters in OP units Position of air filters in UP units Position of air filters in UG units. The life of the humidifying cylinder depends on various factors, which include: proper size and operation, water supply within nominal values, hours of use and proper maintenance. Not more than the first 300 hours of operation: Check the operation, make sure that there is no significant water leakage and check the general condition of the housing.
Quarterly and no more than 1000 hours of operation: Check operation, verify that there are no significant water leaks and replace cylinder if necessary. In some cases, the heat produced can warp the cylinder and, in more serious cases, holes can form in the plastic wall resulting in water leaks into the tray.
