Only use modular units after they have been securely mounted and fitted with protection guards

to suit the application (suitable and tested guards can be supplied on request).

- Installation, electrical and mechanical maintenance and service should only be undertaken

by qualified personnel!

- The modular unit must only be used according to its design parameters, with regard to performance

(F data plate) and mediums passing through it!

The RAL modular and air handling units fulfil the quality requirements of the RAL/RLT Quality Association.

Both air handlicng units series, made from steel profile, and RAL-RLT units are constructed

on the modular system and therefore can be produced and installed in any position. They

are used for heating, cooling, filtering, mixing air and for heat recovery. Their operative range is for

air volumes of 500 m³/h up to 100000 m³/h.

Weatherproof units

Weatherproof units are suitable for outdoor installation (e.g. on flat roofs etc.) They are equipped

e. g. with a weather proof roof as well as a weather protection guard or alternatively inlet- and

outlet cover and a base frame. The outside of the casing is plastic coated.

Hygienic units

Hygienic units are suitable for use under special hygienic conditions, as e.g. in hospitals or in the

food area. The sheet metal parts are coated or made of especially corrosion resisting materials.

The floors are flat for easy cleaning. For cleaning and maintenance purposes the built-in components

are easily accessible and partly withdrawable (e.g. filters).

The installed radial fans can be used for ventilation of:

- clean air

- slightly dusty and greasy air

- slightly aggresive gases and fumes

- mediums up to an atmospheric density of 1,3 kg/m³

- mediums up to a max. humidity of 95%

Store components in a dry place and weather protected in its original packing.

- Cover open pallets with tarpaulin and protect the fans against dirt (e.g. stones, splinters,

wires, etc.). Even weatherproof modules must be covered as their weather resistance is only

guaranteed after installation.

· Storage temperatures between -30° C and 40° C

With storage duration of more than 1 year please check bearings on soft running before

mounting ( Fturn by hand).

· The modules can be transported with forklifts and cranes. If transport is done with cranes, the

use of straps is required, possibly on jack rings if available (F Page 6, Drawing 1) (F weight as

per unit data sheet).

- Avoid distortion of casing or other damages.

· Use suitable assembling means as e.g. scaffolds conforming to specifications.

· Prior to lifting modules, lock all service and access doors.

Installation and electric work must be performed by skilled and

qualified personnel only and in accordance to applicable regulations

and manufacturers instructions.

Service doors of the modules on pressure side must be

equipped with a safety lock for pressure reduction.

With hygienic units

· Supply water for heat exchanger and other units with water consumption

must have the quality of drinking water!

· Unevenness due to casing disconnection in the floor area must be sealed

with leakproof material. We recommend disinfectant proof sealing material

„duct sealing material / Lüftungskanaldichtmittel“ (LKD) coloured silvergrey,

transparent or white from company Adolf Würth GmbH & Co. KG,

Posfach, D-74650 Künzelsau, Germany

· Air damper mounted inside or insulated (double boarded with insulation

inbetween)

With weatherproof units

· The supplied weather-protection roof must be mounted on all units installed

outdoor.

Before installing remove transport cornerpieces (when available)!

· Units must be assembled on a rigid, level foundation or other supporting structures.

F Style and design of foundation must meet the requirements for acoustic, and for the professional

draining of water from drop eliminator and humidifier on site. (Attention to height of syphon!)

· When installing units on impact sound insulation bases between unit and foundation, apply the

following procedure.

- Using a marker draw a ground plan of the complete unit on the foundation.

- Place rubber strips on foundation according to outline.

- Positioning in true alignment of assembled units with rubber strips.

· The flexible connections between duct and air handling unit must be tension free when

mounted. Mounted length of the flexible connection must be shorter than the extended length.

· The modules must be assembled and positioned prior to connecting them with supplied mounting

material. (Drawing 2 and 3)

Electrical connections for built-in components i.e. motors for fans and pumps, electric heaters, actuators

etc. must be in accordance to manufacturers instructions and local ordinances. Electric

heating coils must be equipped with a safety switch according to VDE 0100 Part 420. The safety

switch must be inspected for proper operation after initial installation and after long periods of

downtime. During maintenance of the air handling unit, the electric heating coil has to be checked

for dirt and cleaned if necessary.

If provided, ground cables on flexible connections of fan and duct must be inspected for proper

fixing and retightened if necessary.

 

 

 

Eletrical connections:

If atmospheric phenomenon tubes, drains and overflow pipes ar out there, check that that

externally settled connections ar connected to a syphon with safety

for nonreturn flap and self-filling (depending on size fix a syphon with transition

piece on drain). the peak of the syphon should be in accordance with

excess pressure and air mass of the standard unit so as to avoid suction

and exhaust of air from drain pipes. The exhausting of atmospheric phenomenon needs to

be done unpressurized.

Heat exchangers ar withdrawable. Connecting pipes should be flanged in

a way that the warmth money dealer will be withdrawn once the rim association

is unsnarled.
