MAINTENANCE

WARNING

Before performing this operation, care should
be taken that any of the discharged water does
not come into contact with the operator or
surrounding surfaces. The water can be
extremely hot and can cause severe scalding
and damage to the property.

If the relief valve discharges periodically, do
not plug it. If replacing the valve does not stop
the discharge, contact your local authorized
service agent or the Hatco Corporation.

air inlet holes on the side or back of the unit.

damage to any wiring or components. Check
also for any signs of water leakage at any of the
plumbing connections. If there are signs of any
damage or leakage contact the Hatco
Corporation or your authorized service agent.

7. The relief valve should be manually operated at

least once a year to ensure proper operation.
