Emergency Shutdown; Safety Labels - York YGWH 115 Installation, Commissioning & Operation

Refrigerants and Oils
Refrigerants and oils used in the unit are generally
nontoxic, non-flammable and non-corrosive, and pose
no special safety hazards. Use of gloves and safety
glasses is, however, recommended when working on
the unit. The build up of refrigerant vapour, from a
leak for example, does pose a risk of asphyxiation in
confined or enclosed spaces and attention should be
given to good ventilation.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods (e.g.
steam cleaning) should not be used on any part of the
pressure system as this may cause operation of the
pressure relief device(s). Detergents and solvents,
which may cause corrosion, should also be avoided.

Emergency Shutdown

In case of emergency, the control panel is fitted with an
emergency stop button (RED) when pressed it removes
the electrical supply to the control circuit thus shutting
down the unit. The button is locked in the closed (OFF)
position and has to be rotated to reset it.
