O&M Instructions – Heat Pump
Do not open any access panels or touch electrical components while voltage is applied. Only a qualified electrician
equipped with the proper tools and wearing appropriate body protection against electrical hazards should carry
out such work.
Before removing any panels from the enclosure, or dismantling any part of the unit, isolate from the main
electrical power supply. Lock the isolator in the ‘OFF’ position and remove the fuses. Attach a label to the isolator
switch carrying the warning ‘WORK IN PROGESS – DO NOT APPLY VOLTAGE’. Do not switch on electrical power or
attempt to start the unit if a warning label is attached.
Units incorporating Low Temperature Hot Water (LTHW) heating coils must be isolated from the water supply
before undertaking any work. Attach a label to any closed isolating valves carrying the warning ‘WORK IN
PROGRESS – DO NOT ADJUST VALVE’. Do not open valve or attempt to start unit if a warning label is attached.
When Envirotec products are installed over doorways or within the ceiling framework, most maintenance or repair
work will be carried out at heights in excess of 2 metres. Suitable precautions should be taken to ensure that any
access equipment used, ladders, towers, etc., are isolated from passing human traffic by the use of an appropriate
barrier/notice system. Any barriers used should be positioned at a suitable distance to remove risk of injury to
passing personnel from dropped tools/components. All equipment used to gain access to work at height must be
properly secured, and manned by sufficient support staff to meet National/Local safety regulations.
Attention should be paid to the weight of units or individual components, particularly when being removed from
the original installed location. Suitable lifting equipment, including slings, straps, hooks, etc. should be used as
appropriate.
The door curtain must be installed, maintained, repaired and removed by a qualified installer or qualified service
person.
