Hydra 798 Iss.10 – 04/18
USING THE COOLING COIL
The EHT and HT models have an internal cooling coil fitted. Access for the cooling coil is via two bulkhead fittings on
the rear panel.
The L and M Models have a similar facility; access is via the two labeled connectors in the rear of the bath. Hydra
models L and M manufactured before March 2005 do not have this cooling pipe fitted).
Water passed through the coil will substantially reduce the cooling time. To avoid any hazard from the expansion of
water to steam do not use water at temperatures in excess of 100°C and ensure water is drained from the coil before
setting the Hydra above 100°C.
