VPVM - Large Area Outlet

Dimensions in mm, weights in kg.
These technical conditions define a series of the manufactured sizes and versions of the following large outlets (hereinafter outlets): VPVM - K 400, 600, 800, 1000, 1200, 1480, VPVM - S 400, 600, 800, 1000, 1200, 1500, 2000, VPVM - R 800, 1000, 1200, 1400, 1600, 2000 , heights of 750, 1000, 1250, 1500 and 2000 mm.
They apply to manufacturing, designing, ordering, deliveries, installation and operation.

I. GENERAL

1. Description

Large outlets are terminal air-conditioning elements for the distribution of air in air-conditioned and ventilated rooms. They are intended for the inlet of treated outdoor air directly into the living (working) area. In order to ensure stabilized air flow in the living area, the temperature of inlet air must be lower by 1 to 3°C then the temperature of air in the ventilated room. Outdoor air is let in with low velocity at the floor, to take harmful substances from the living area to ceiling.

2. Design

The following types of outlets are supplied: round outlets to be installed into a space, wall-mounted outlets with semi-circled ground plan, and corner outlets with quarter-circled ground plan. Piping is connected to outlets from above to round connecting socket. Outlets are supplied with or without control flaps.

Outlets are intended for installation in environments protected from weather conditions, class 3K5, according to ČSN EN 60 721-3-3 and in BNV rooms according to ČSN EN 1127-1.

IV. MATERIAL

Outlet parts are made of steel sheet. The surface is finished with white baking varnish of RAL 9010 colour shade. Other shade requirements have to be agreed with the manufacturer in advance.

V. PACKING, TRANSPORT, ACCEPTANCE, STORAGE

Outlets are supplied in crates, covered with shrinkable foil, by covered transportation means. When handled during transport and storage, outlets must be protected against mechanical damage.

Provided no method of acceptance is determined in the order, outlets will be considered accepted when being handed over to the carrier.

Outlets must be stored in covered rooms, in environments free from aggressive vapours, gases and dust.

Temperature range of -5 to +40 °C and relative humidity up to 80% must be kept in the storage rooms.

The manufacturer provides outlets with an 18-month guarantee after having been first put into operation, however 24 months after the date of dispatching.
