PIPE CONNECTIONS
CWR UNITS
Pipework is terminated with end caps, adjacent to the access panel at the left hand side. All pipework is 15mm copper
water pipe.
ELECTRICAL CONNECTIONS
Mains, control and interconnecting cables must be supplied and fitted by the installer.
Installer wiring must be carried out in accordance with IEE regulations and local codes.
Cables must be size compatible with the recommended fuse for a given system.
An isolator switch should be positioned within easy reach of the indoor unit.
The equipment
MUST
be earthed.
Cables may enter the CWR unit at the top, back, left or right hand side. If the left hand side is used, sufficient cable
length should be allowed to run the full length inside the unit. Ensure that the cable is secured to the chassis flange
along the length of the unit and to the holes provided in both hanger brackets.
Cable glands suitable for stranded cables are supplied and should be used to secure all cables. Installers must supply
a method of securing any solid sheathed cable.

CONDENSATE REMOVAL
Condensate is collected in a drain tray incorporated within the fascia panel.
An outlet connection is provided at the back/right hand side of the unit for connection to a 12mm bore flexible pipe.
Run the outlet pipe to gravity drain ensuring that there are no kinks or blockages.
An optional condensate pump kit is available with 5m lift.
FASCIA MOUNTING
Electrically isolate the unit. Once the chassis has been installed, the fascia should be refitted, (Fig. 6). When complete,
refit the grille, filter and end panels: fit the fascia support bracket with No.10 screws, (Fig. 7).

AIR DEFLECTION
The air off vanes are manually adjustable to allow horizontal and downward air deflection.
It is suggested that, in cooling mode, the discharge is directed horizontally along the ceiling. In heating mode, vanes
can be moved to a 30
/
downward discharge. Refer to page 3 for discharge velocities.
It is also possible (by reversing the discharge boxes) to move the air off vanes to a 90
/
downward discharge, creating
an air curtain.
