Efficient plant is but one aspect of the reducing energy costs and must be accompanied by reducing the energy demand of buildings served by that plant.

They relate to the setpoint or variable numbers used with the KP02 unit. Units have two, three or four compressors, each with their own interlaced circuit in a single coil.

Lennox advances the art of rooftop air conditioners Published: Using The Kp07 Remote Graphical Display – Recording of successive status of pre-defined variables to create analog and event histories. Homes England pushes for modular methods Tests prove that underfloor heating and carpe Control ; Cold Settings: At their simplest, they incorporate a fan to draw air from the space, filter it, introduce fresh air, provide heating or cooling and then deliver the treated air to the space.

Page of Go. While standard Flexy II units use belt-driven centrifugal fans, Lennox also offers units with high-efficiency plug fans with variable-speed control to enable air volume to be matched to requirements.

As Herve Dumont explains, for much of the year, free cooling by introducing controlled amounts of fresh air will enable the desired environmental conditions to be provided — without having to use mechanical cooling.


Warranty Lennox shall guarantee the casing of its Rooftop units modes. To this effect, the motors are fitted with variable pulleys.

Do not discard the seals Figure 55 5. To print the manual completely, please, download it. Key [M] allows you to move successively and in a loop from one mode to the next.

Disposable, or metal frame. Above all, ensure that all the adjustable returns are facing outward 1 – figure 6. Go to the machine component status.

Take a deep breath Underfloor heating meets new Building Regulat Wrong Air Flow If the pressure differential obtained by the analog sensor [V21] is less than the setpoint value [C88] for more than 20 seconds, and if the blower fan has operated for more than 1 minute 30 seconds, the air flow safety system is activated and stops the ventilation.

The reductions in running costs are demonstrated by Lennox in comparisons of the original Flexy range with the Flexy II range.

Designed for low weight and energy-efficient operation, the Lennox Flexy II range of rooftop air conditioners makes extensive use of aluminium in its construction. Control ; Hot Settings: To rectify this, it may be necessary to modify the pulley and belt setting. Vacuum clean or blow the dirt. Maintenance Plan – It is recommended to keep a minimum stock of common replacement parts in order to be able to carry out regular maintenance operations i.

The projects will be predominantly with Defence-related and Government establishments but w This be addressed to Lennox and the supplier or distributor for allows you to open the panels for maintenance and information purposes. Compressor stopped in anti-short cycle. Condenser Water Temperature Too Low If the temperature of the water loop is less than or equal to the preset setpoint [C80] during the operation of one of the compressors, the condenser safety mechanism is applied.


Life-cycle cost was highlighted by customers as one of the top priorities and is listed by Lennox ahead of first cost. The hub and the pulley will separate from each other. The aim of air supplying regulation by the air damper is to even out the temperature of supplied air to a value close to The main aim of supplying air regulation is to maintain the the average of the neutral zone.

Operation of the grids – Balancing grids are installed on fresh air side in order to compensate for the higher pressure drop on the ducted return air side. It is fitted with a AT fan which curve is shown on page xxx and a 2.

Measure the absorbed amps If the absorbed amps are greater than the rated values, the ventilation system has a lower pressure drop than anticipated.

In addition, if the antifreeze thermostat is opened, the 3rd safety level is immediately automatically maintained. Comments to this Manuals Your Name. Lsnnox a product redevelopment provides opportunities not just for upgrading but also responding to changing market expectations.

Ken Sharpe looks at the growing pressure on HFC refrigerants and how one manufacturer has developed a concept that addresses the issues for large systems. Fexy is why the compressors cannot be started, even if requested to do so by regulation, unless the time since lennoxx were last put into operation is greater than six minutes.

Condition ; Weekend On ; Ventilation Settings: However, the energy used for mechanical cooling is but a small part of total annual energy consumption.

They are usually turned inside-out for transport. Exploiting free cooling relies on air movement using fans — so that fan energy consumption is greater than compressor energy consumption. Within the scope of their application, they could be regarded as glexy the function of chiller and air-handling unit in a single package — but for a much lower capital cost and installation time, and with single-source responsibility.
