Panasonic PWW 4000 manual Unit Assembly, Brackets, KO bracket, Cu / Al heat-exchangers

Unit Assembly

Brackets

Brackets for wall and ceiling assembly (2 per unit) are inserted into the openings at the back of the unit and at- tached with the supplied screws.

Components that are attached directly to the units, such as mixed-air boxes or filter boxes, are equipped with a bracket adapter.

When using customer-installed bracket constructions, the minimum distance to the wall (dimension "e") must be observed!

Connection to the heating system

◊The REMKO PWW is to be connected by the cus- tomer via the shut-off valve, automatic air bleeder and screws in the supply and return lines.

Use compensators if necessary.

◊It does not matter which side is connected. Right or left.

◊The units operate on the principle of counter-current.

◊The water (supply line) usually comes in at the bot- tom. The water usually goes out (return line) at the top.

The brackets must be current-free and screwed on to the unit and the wall/ceiling.

Cu / Al heat-exchangers

The heat-exchangers are made of copper pipes with alu- minium plate fins pressed onto the outside. The plate fin package is surrounded by a galvanized, zinc-plated steel frame.

The collector and the distributor are made of steel. Please observe the following for the heat-exchangers:

◊The heating medium connection is made via threaded connectors.

◊The maximum operating temperature is 130 °C.

◊The maximum operating pressure is 16 bar.

◊The heat-exchangers are not suitable for operation with steam or thermal oil.

When the fan is idle, the heating medium supply must be interrupted.

Draining in case of frost

It is not possible to statically drain the heat-exchanger completely. The heat-exchanger can only be com- pletely drained when compressed air is used.

Important information about frost protection!

To prevent frost damage, a frost protection mechanism must be attached for temperatures below 0 °C.

There may not be any water in the heat-exchanger for systems taken out of operation in rooms susceptible to frost. The remaining water must be blown out with com- pressed air.

If this is not possible, the heating medium (water) must be mixed with a suitable anti-freeze.

No guarantee claims can be made for frost damage on the heat-exchanger!
