HEALTH & SAFETY WARNING

As the Heat Pump contains electrical and rotational equipment, it is recommended that ONLY competent persons carry out any work on this type of machine 

(see guarantee). Isolate electrically before entering machine or removing panels.

This appliance is not intended for use by persons (including children) with reduced physical,sensory or mental capabilities, or lack of 

experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible 

for their safety. Children should be supervised to ensure that they do not play with the appliance.

The Calorex TTW units are designed for installation in a heated room, adjacent to the poolroom.

INSTALLATION MODELS TTW30/33/55/60.

1.  Remove machine from packaging.
2.  Check both sides of wall, mark out apertures ‘D’ and ‘E’ in required location 

and ensure they are level.

3.  Cut out apertures ‘D’ and ‘E’ with due consideration to structure and safety 

using a suitable lintel to bridge the gap.

4.  Remove the four bolts holding the dehumidifier to the wall plate and also 

the earth lead.

5.  Locate the wall plate in apertures and ensure it is level. Drill and fix using  

12 ‘C’ holes and wall plugs /screws provided. Hole size 6mm (No 10) x 
60mm.

6.  Lift the dehumidifier on to wall and replace six M6 bolts ald wall plate earth 

lead. 

7.  Fix supplied cavity bridging pieces and air inlet/outlet grilles, ensure all joints 

are sealed with silicon caulking.

8.  Electrical supply to the unit must be sized according to data on serial 

number label paying special attention to I.E.E. regulations latest edition 
regarding the special conditions governing electrical supply to machines in 
potentially damp areas. The machine should be installed in accordance with 
EMC2004/108/EC.

9.  The electrical supply should be connected to the terminal block mounted 

on the side of the bracket supporting the compressor. Brown/red to 'live', 
blue/black to neutral and earth to the stud provided.

10.  Fan mode switch can be set to cycle fan when humidistat senses demand 

but should be set to continuous to promote good air circulation and reduce 
condensation. Note that on models fitted with LPHW the fan(s) will start 
automatically whenever there is an air heating demand. On 'X' models 
fan(s) will stop during defrost cycle.

11.  Locate pipe from drip tray and run away to waste, a short length of 10mm 

pipe is provided which should be led into a fixed waste pipe (ensure an air 
gap, tun dish).

MODELS WITH L.P.H.W FITTED

12.  Connect water circuit piping to 15mm stubs projecting from side of 

machine as per diagram below:

13.  It is recommended that isolating valves are fitted to enable isolation of the 

machine in the event of service. 
Complete water circuit as per diagrams overleaf. 
(a) Circulating pump must be sized to take into account the design flow 
rate of the machine plus the water system resistance. For Pressure drops 
see data section.

12V REMOTE HUMIDISTAT, THERMOSTAT, & REMOTE ON/OFF 

CONNECTIONS

(These options need to be specified when ordering the 

dehumidifier)

REMOTE HUMIDISTAT

14.  Remove link wire from mains in terminal block marked ‘Remote Humidistat 

and connect remote humidistat as shown below, ensure dial on internal 
humidistat is set fully anti-clockwise (ie maximum dehumidifcation).

REMOTE ON/OFF

15.  Remove the link from the mains in terminal block marked Remote On/Off. 

and connect to a switch as shown below.

'P' MODELS WITH RESISTANCE HEATER

16.  Connect remote air thermostat as shown above to mains in terminal block 

marked Remote Thermostat

17.  Ensure safety thermostat(s) below are set, ie push red button(s).
18.  Replace front cover, turn on electrical supply and turn humidistat towards 

20%. (Unless remote humidistat fitted, see note 14 above) unit fan will 
start, followed 6 minutes later by the compressor.

19.  It is recommended that the fan mode switch is set to continuous, as in 

cycle mode the fan and heaters only run together if there is a demand for 
dehumidification.
