Assembling stacked casings (A and B) with a thermal wheel 

recuperator (C)

Fasten the feet on section B to the middle panel (1) with two TH 

6 x 20 screws in the holes provided. 
Holes are provided for this purpose.

 

Assembling adjacent casings

The  first  air  stream  (fig.1)  is  installed  in  the  same  way  as  on 

horizontal air handling units. (see block interconnection).
The second air stream is connected to the outside (Fig. 2) in the 

same ways as the sections. The insides (inaccessible) are 

connected from inside when possible and/or using the outer lugs 

on the top of the box (impossible on outdoor handling units on 

account of the roof).

 

Ceiling installation

Suspended units must be placed on a metal section suspended 

from the building structure. Each pair of feet must rest on a metal 

section. Each pair of feet must rest on a metal section.

These sections are to be provided by the fitter and must be cut 

to suit the layout of the room and be sufficiently rigid. The sections 

should not block access to the drawers and doors on the unit. 

Leave space for platform access on the connections side.

 

Outdoor installation

Air handling units installed outdoors must be protected by a roof 

(Fig. 1) or overhang (Fig. 2). These components are generally 

delivered in kits and adapted to each configuration.

Overhang

 

Fitting the roofs

Affix the gasket 

B

 along the length of the unit (50 x 20 foam 

gasket).
Fit the roof panels along the entire length of the unit, placing a 

foam seal (supplied by CARRIER) between each panel.

C

C

B

Assemble the panels as per the roof diagram and drawing  

supplied with the unit

a  M6 x 16 screw

b  Sealing washer

c Gasket

Assemble the panels to side A of the unit as shown in the drawing 

opposite:
Then assemble the panels to side B, pressing on the roof to create 

the curve. Fasten the panels to the box.

a  Sealing washer

b  Self-tapping screw (supplied)

Sealing rivet

In addition the rules mentioned on the previous pages, special 

care must be taken with the hydraulic system (do not forget the 

risk of freezing temperatures). 

If  the  unit  is  fitted  with  an  external  air  intake,  we  recommend 

protecting it from prevailing winds and any exhausted air or gases 

(chimneys, roof extractors, etc.). Follow the requirements in 

standard EN 13779.
If the unit is installed on a deck or patio with a top intake and/or 

discharge, the unit must be placed above the roof or deck/patio. 

Locations where ducts and pipes extend through the roof or deck/

patio must be completely watertight.
