Fitters notes	Thermostats
Installation	If the risk of water droplets or water spray is
	present, fit a top plate. The plate increases the
	grade of enclosure to IP 44 and is suitable for all
	KP thermostats. The top plate must be purchased
	separately (Code no.: for single unit, 060-109766;
	for dual unit, 060-109866).
	To obtain IP 44, cover all holes in the backplate of
	the thermostat.

If the unit is to be used in dirty conditions or where it might be exposed to heavy spray it should be fitted with a protective cap. The cap can be used together with either an angle bracket (060-105666) or a wall bracket (060105566).

If the unit risk being exposed to heavy water influence a better grade of enclosure can be achieved when mounting the product in a special IP 55 enclosure

The IP 55 enclosure is available for both single unit (060-033066) and dual unit (060-035066).

KP thermostat with air sensor Remember that the differential is affected by air circulation around the sensor. Insufficient air circulation can increase the differential by 2-3°C.

Place the room thermostat so that air is able to flow freely around the sensor. At the same time, ensure that the sensor is not exposed to draughts from doors or radiation from the evaporator surface.

Never place the thermostat directly on a cold wall; this increases the differential. Instead, mount the unit on an insulating plate.
