TROUBLESHOOTING
5.1 High Water Temperature
Issue
Solution
Water too hot
High water temperature can generally be attributed to supply water
temperature, radiant heat input from ambient conditions, or heat
transfer from adjacent piping systems. Insulate or isolate as required.
If radiant heat is a continual problem, a scald protection valve should
be retrofitted to the shower for personnel protection reasons.
Assure the thermostat is wired correctly (thermostat opens on rise in
temperature and closes on fall).
5.2 Freezing
Component
Solution
Freeze
Protection
Valve
The freeze protection valve should be tightly closed at fluid
temperatures of 40°F (4.4°C) and above. To test the freeze
protection valve, see “4.6.1 Testing and Cleaning Freeze and Scald
Protection Valves” on page 4-10.
Eyewash only
freezing
Trapped water in the eyewash due to:
• The 3-way self-draining valve is plugged and needs to be cleared.
• The eyewash covers were replaced too quickly — not allowing
water to drain back to atmosphere (wait 30 to 90 seconds to
completely drain the eyewash).
• Interrupted power supply— check continuous power supply to the
unit and the thermostat. Shower maximum amperage load is
shown on the Encon
®
equipment label located on the junction box.
Shower Head
only freezing
Slight freezing of water droplets is to be expected in extremely cold
environments. This condition does not affect the operation of the
shower, as ice crystals will be removed upon shower activation.
