4.) Installation

The preferred installation position is vertical with the pump

facing down. When horizontal installation is unavoidable, take

care to purge the remaining air since this is more difficult in the

horizontal position. Please make sure that beneath the unit (or

on the pump side when installing horizontal) a free space of

approx. 1.2 inch remains which is necessary to service the

pump in case of trouble.

The unit must be installed on a non-flammable surface and

must be installed indoors. Avoid any flammable materials in the

immediate vicinity of the unit.

The unit is mounted using the mounting grooves at the bottom

rear of the junction box.

5.) Electrical connection

Important advice: Electrical work may only be performed by a

properly licensed Electrician and has to conform to all relevant

codes and requirements.

All internal connections of the EHR are pre-wired so that only

the mains connection and, if applicable, the connection of an

external room thermostat (Model Laing RTS) or room

thermostat with timer (Model Laing RTU) need to be done.
