Page 3: Valve Positions
OPTIONAL CONTROL VALVES 2 port on/off valves or 4 port diverting valves are available as factory fitted options. (4 port modulating valves are also available - contact TEV Technical Sales Department). 2 pipe cool only systems require one valve per fan coil. 2 pipe heat/cool systems (supplied from a reverse cycle chiller, or chiller + boiler) require one valve: if using an auto changeover thermostat, they also need a means of signalling heating or cooling status of the flow eg a pipe thermostat (kit shown on page 23).

Is the pipework insulated right up to the unit ? Have all pipework joints been carefully checked for leaks ? Is the fuse size correct ? Is the interconnecting wiring correct ?
Page 11 CWM (L) USER MAINTENANCE ISOLATE THE UNIT ELECTRICALLY BEFORE COMMENCING ANY MAINTENANCE WORK In order to maintain maximum efficiency of this unit, it is important that the filters behind the return air grilles are cleaned regularly. To remove filters: Clean the filters by washing in tepid water, vacuuming or by tapping gently outside the building. To replace filters: THE UNIT SHOULD ALWAYS BE USED WITH A FILTER.

Page 18 3. WIRING CWM L a) Route the harness from the fuse along the back panel using the cable clamps, ensuring the harness is above the cabinet fixing brackets b) Remove and discard the violet wire between the pcb relay and terminal 7. Connect the black wire from the fuse assembly to the PCB relay, Route the blue wire alongside the existing harness and connect to terminal N on the terminal rail.

5m HIGH CONDENSATE PUMP KIT FOR CWM (L) UNITS 55600420 ITEM DESCRIPTION Pump Assembly This kit is for use on all versions of CWM and CWM L units and is for condensate removal where a lift of up to 5m is required.
Page 20: Troubleshooting
WIRING Locate the black, blue and red wires in the unit near the pump and remove the cover from the black and blue wires. Connect: (i) Black wire to terminal L on the pcb (ii) Blue wire to terminal N on the pcb The plastic cover over the pcb can be removed for convenience: retain the cable tie.

PIPE THERMOSTAT KIT 96200070 This kit is for fan coils on 2 pipe systems supplied from a reverse cycle chiller (or chiller + boiler) and fitted with an auto changeover thermostat, to enable a single valve to operate in both heating and cooling modes. It prevents the room thermostat calling for cooling and the valve being opened when the flow is hot water, and vice versa.

This instruction is also applicable to return air sensor spare 04000012S The sensor can be fitted to the return air inlet to an air conditioning unit to improve operation eg. if the wall thermostat is placed outside the space being conditioned, or if there is considerable stratification in a room with a high ceiling, where the wall thermostat would not measure a representative temperature.
