CWW CHILLED WATER WALL MOUNTED UNIT INSTALLATION

The CWW CHILLED WATER wall mounted unit may be installed at low or high level.

The installer supplies:

* 4 off M6 (or equivalent strength) Rawlbolt shields, bolts and washers.

* Insulated pipework.

* All mains wiring with suitable isolation.

* Condensate drain (Minimum 10mm bore for gravity drain, 8mm bore when fitted with a condensate pump).

* A cross-headed screwdriver for releasing the end cover fasteners.

* Method for securing solid sheathed cables if these are used.

Unpacking

Carefully unfasten the banding and lift off the outer cardboard carton sleeve.

The following are supplied:

* CWW unit (in protective sleeve, held between two polystyrene end caps).

* Two cable glands suitable for flexible, pre-sheathed cable.

* A wall mounting bracket also held between the two polystyrene end caps.

* Envelope containing operating instructions to be left with the end user.

1 Lift the CWW unit from the inner cardboard sleeve complete with the two polystyrene end

caps; (this will require 2 people for sizes 55 to 85).

2 Remove the wall mounting bracket and carefully remove the two polystyrene end caps

and the protective sleeve from the CWW unit.

3 Remove both end covers by removing the self tapping screws, one on each end trim.

By pulling the end covers sharply they can be removed from the backpanel and fascia.

Chassis Mounting

NOTE: It is generally easier to fit kits prior to mounting the unit and connecting the pipework.

1 Ensure that the wall is flat and will support the operating weight of the unit, (see below).

2 Ensure that sufficient access is left around the unit for future kit fitting, servicing and maintenance, (Fig. 1).
