MAINTENANCE
General
This Product is precision engineered and should give continued safe and controlled
performance, provided:
1. It is installed, commissioned, operated and maintained in accordance with
manufacturers recommendations.
2. Periodic attention is given, when necessary, to maintain the product in good
functional order.
The rada Exact 3B Shower Valve is designed for the minimum of maintenance in
normal use. The only serviceable parts are the inlet filters which should be checked
and cleaned every 12 months. If a malfunction occurs with the Thermostatic Cartridge
then this will necessitate a complete cartridge replacement.
Note!
The cartridge contains no internally serviceable parts.
If you require a Rada trained engineer or agent, refer to section: ‘Customer Service’.
Planned Maintenance
Important! For Type 3 Valves use the In-Service Tests given in the TMV3
Requirements Manual. In the absence of any other instruction or guidance on the
means of determining the appropriate frequency of in-service testing, the procedure
contained within this guide (taken from Annex F of D08) should be used.
For other commercial installations it is recommended that the correct blend setting
is checked every 6 months and that the In-Service Test procedure is followed every
12 months.
Critical Components
Irrespective of supply and usage conditions or the evidence of in-service tests, critical
components should be replaced at intervals of no more than 5 years.
