1. RECOMMENDATIONS AND SAFETY
SETPOINTS
Read the instructions in the manual carefully before starting to install the apparatus and keep the manual in good condition close to the apparatus
throughout its working life.
1.1 Individuel protection
• This apparatus can be used by children aged over aged 8 years and people with reduced physical, sensory or mental capabilities, or lacking in expe-
rience or know-how, (providing they) are properly monitored or are instructed in the safe use of the apparatus, and if any possible risks are clearly
understood.
• Children should not be allowed to play with the apparatus. User cleaning and maintenance must not be carried out by unsupervised children.
1.2 Installation and maintenance precautions
• Installation of an VEX unit can be dangerous due to moving or powered up components. This equipment should be installed, commissioned and
serviced by trained and qualied personnel, observing Standards and standard good practices.
• All servicing or maintenance operations requiring the access doors to be opened or one or more components to be removed must be carried out by
a qualied technician.
• All electrical connections to the equipment must carried out by a technician in accordance with requirements laid down in the NF C 15-100 Standard.
• In particular, a contact separation device with an opening of at least 3mm on each pole as well as a protection device with an appropriate rated
current should be installed in the inbuilt raceways (circuit breaker). Copper conductor sections are dened in sections 2.9.3, 2.9.4 and 2.9.5 of the
installation manual.
• The product must be powered down before any maintenance or cleaning operation.
• Make sure that the unit cannot be accidentally started up.
• To avoid any risk of accident, if a power cable is damaged it must be replaced by the technician who installed the product, or another qualied
technician.
• In the event that the motor overheats, its linear modulation will be reduced. When it exceeds its maximum internal temperature, the controller powers
down the motor and restarts it automatically after cooling. In the event of motor failure (motor integrated circuit failure signal, phase failure, motor stal-
led, shorted to ground or internal short circuit, intermediary or network reduced or excessive voltage, peak current fault) an alarm triggers apparatus
power down. Disconnect power supply (circuit breaker on the electrical panel), check that nothing is restricting unit operation (e.g. blocking, friction,
clogged wheel, abnormal noise...) and wait one hour before powering up again.
• If the problem persists, contact your installer or dealer.
• Use only manufacturer’s original parts.
• For units tted with an electric heating coil: in the event of multiple failures in electrical coil power control (at least two sensors failed) and in case of
overheating in the air input chamber (Ambient temperature > 80°C), an automatic rearming thermostat triggers electrical coil shutdown. In addition,
the electrical coil is tted with a manual reset thermostat which triggers at 120°C and is located in a sleeve between the resistors.
• To maintain the guarantee, no modications must be made to the apparatus.
• To ensure correct operation, the apparatus must be regularly maintained.

2.4 Unit Assembly
2.4.1 General information
Assemble the unit’s cross members on a at, stable surface (at surface for condensates).
It is advisable to install an anti-vibration device between the Unit’s legs and the frame (e.g.: pads or mats) and between the pipe ttings and the duct
system (e.g.: exible cuff) to dampen any vibration generated by the motorised fans.
During unit installation and connection of ducts and electrical cables, make sure not to block the access points so that internal operational components
can be easily extracted, thus enabling electrical connection of the unit.
Space required for maintenance: to enable lter replacement, the 2 side doors must be able to open to a min. of 90°. The central black door must be
able to open to 180° for access to switches and controls.
Provide the space and height required for connecting a siphon to drain the condensates from the exchanger and cooling coil. See section 2.8.1.

2.7.5 Constant pressure option
The kit consists of three RJ12 cables (labelled R8, R9 and R10) connected to the two PTH pressure sensors. Each sensor is linked to two metres of
transparent exible tube which is connected to 1 black pressure outlet. 4 self-tapping screws are provided in a plastic bag. The assembly is wired up
and constructed in the Factory and placed on the air input and output sidewall. Only the black pressure outlets are to be installed in ducts.
The upper PTH sensor should measure the pressure difference between the air outlet and the ambient air outside the unit. Its address arrow is set at
position “6”. The transparent hose is connected to the «-» sensor terminal (depressurised duct). Leave the «+» terminal exposed to fresh air. Drill a
10mm Ø hole in the outlet duct in order to insert the pressure outlet. Secure the pressure outlet, using two self-tapping screws. Remember to carefully
seal around each pressure outlet.
The lower PTH sensor should measure the pressure difference between the air inlet and the ambient air outside the unit. Its address arrow is set at
position “5”. The transparent hose is connected to the «+» sensor terminal (pressurised duct). Leave the «-» terminal exposed to fresh air. Drill a 10mm
Ø hole in the outlet duct in order to insert the pressure outlet. Secure the pressure outlet, using two self-tapping screws. Remember to carefully seal
around each pressure outlet.

Warning: the transparent tube must descend from the PTH pressure sensor to the duct’s black pressure inlet without allowing a low point beneath it.
Under certain conditions the air in the hose could condense. Water stagnation in the hose causes incorrect measurement leading to poor unit control!
Warning: for the best results, pressure should be measured where there is less risk of turbulence, that is to say, on a straight length of duct. The mini-
mum distance to be maintained from any turbulence is at least twice the diagonal of a rectangular cross section, and at least twice the diameter of a
circular section.

2.8 Hydraulic connection
2.8.1 Generalities on condensate connection
Fit all condensate drains with a siphon (plate heat exchanger and cooling coil optional). Siphon height is calculated according to the under or excess
pressure in the apparatus, in order to enable the evacuation of condensates and prevent leakage of air from the unit.
Caution: the siphon must always be lled with water before the unit is started up. Risk of water evaporation during summer months. In order to have
greater water capacity, it is advisable to use a minimum of a Ø32mm diameter siphon (for VEX520-525-530 sizes, use a Ø20 to Ø32 reducing sleeve).
Caution, if risk of freezing in winter, be
prepared to insulate the siphon and the
drainage components if they are in an
unheated atmosphere.
Siphon calculation
"P" being the maximum pressure in Pa inside an operating unit, with a safety factor increase of 20  % (10 Pa=1mm of water column). Warning, be
prepared for more load reductions, (higher or lower pressure) with clogged lters!
Section of the unit with low pressure (at exchanger connection):
H1(mm) >= P/10
Hs >= Px0,075
Example: calculating a low pressure of 500 Pa, i.e. P=600 Pa with safety coefcient.
H1 >= 600/10 →H1 >= 60 mm et
Hs >= 600x0,075 →Hs >= 45mm

1313
In terms of exchanger condensates, the following, maximum total fan pressure can be safely used:
VEX520 à VEX540 (Everest XH 1000 à 2300) P max. = 800 Pa
VEX550 (Everest XH 3500) P max. = 1100 Pa
VEX560 à VEX580 (Everest XH 4500 à 7000) P max. = 1400 Pa
Section of the unit under pressure (at cooling coil connection):
H1 >= 35 mm
Hs(mm) >= P/10
Example: calculating a pressure of 500 Pa, i.e. P=600 Pa with safety coefcient. H1 >= 35 mm et Hs >= 600/10 →Hs >= 60 mm
In terms of internal cooling coil condensates, the aerolic blower system pressure can be used.
2.8.2 Condensate exchanger connection
Our condensate tanks are equipped with an aluminium diameter female tube.
Glue a corresponding male diameter PVC tube (for siphon connection) (see diagram below).
Ø20 mm inside dia.(female) Aluminium tube,
model VEX520 to VEX530
Ø32 mm inside dia. (female) Aluminium tube,
model VEX540 to VEX580
2.8.3 Condensate cooling coil connection
Our cooling coil condensate tanks are tted with a drain plug connected to a exible extensible tube opening at the front at the height of the raceway,
and under the cooling coil. The end of the exible PVC has an Ø32 male tting. Connect the exhaust outlet to a siphon (see section 2.8.1) by gluing
on an Ø32 female PVC cap.
2.8.4 Internal cooling coil water collector connection
For collector diameters and their location, see section 3.4
Collectors have a standard thread. Connect the cooling coil water collector’s water inputs and exhaust outlets.
The water input and outlet collectors are marked on the side panels of the unit (the water circuit is always counter to the air ow, for a cooling coil of at
least two rows). It is advisable to hold the collector with pair of pliers during connection in order to avoid damaging which can cause leakage.
Br sure to seal the collector connectors and provide either an expansion joint or exible connector in order to absorb any possible expansion or
contraction.
For nominal diameters of 3-way valves, see section 3.4
Caution: The cooling coils accept a maximum pressure of 8 bars.

1414
2.9 Connection to the mains power supply
Caution: electrical connections must be carried out by qualied electrician, wearing appropriate Personal Protective Equipment. Never work on the
unit when it is powered up. Electrical connection must be carried out in compliance with the NF C 15-100 Standard. Each power supply network must
be protected by an omnipolar circuit breaker with a contact opening distance of 3mm. For a single-phase power supply, use a Type A leakage current
differential circuit breaker. For a three-phase phase power supply, use a Type B leakage current differential circuit breaker. For these two types of power
supply, we recommend a differential sensitivity of 300mA. The recommended amperage for each circuit breaker, depending on size of unit, is dened
in sections 2.9.3, 2.9.4 and 2.9.5. Maximum recommended ambient temperature <45°C. Do not forget to connect the Earth.
2.9.1 Main Control – Power
The unit has an electric mains power circuit and a electric battery circuit. Each circuit has its own built-in "control - switch" in a compartment located
behind the black door at the top of the unit.
Electrical connections are carried out in the terminal block located in the lower part of the front of the unit (see diagram below).

Unscrew the cruciform screw of the access door to the terminal block. Then unscrew the 2 cable gland support screws. Thread the cables through
cable glands in order to ensure they are sealed. After connecting the power and control cables, install a seal between the edges of the cable gland
support and the junction box.
Watertight seal on the edges of
the cable gland support
The rigid power cable conductors tted with connectors can be plugged directly into the spring terminals (no tools required). Conductors can be
released using a screwdriver and turning the orange latch located in front of the conductor’s insertion hole.
Flexible conductors without connectors must be inserted by pressing the latch to release the spring (see photo below).
By applying a very light force on the latch, you can check that the conductor is correctly inserted if the latch goes in without resistance by 1mm.
