Marstair CWW-L Installation

CWW-L CHILLED WATER WALL MOUNTED UNIT INSTALLATION
The CWW CHILLED WATER wall mounted unit may be installed at low or high level. To operate the unit the end user
will require an electronic remote control (available separately, part number 55500309). This control will operate any
number of 'L' units individually.
The installer supplies:
* 4 off M6 (or equivalent strength) Rawlbolt shields, bolts and washers.
* Insulated pipework.
* All mains wiring with suitable isolation.
* Condensate drain (8mm diameter).
* 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-L 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-L 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-L 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).
