Continuous product development may give rise to specification changes without notice.
5 Maintenance instructions
5.1 Service schedule
For a service schedule, see Operation and Maintenance for Envistar Flex, under
order-specific documentation at
5.2 Periodic inspection
The operation parameters for the reversible heat pump must not be changed
unless a check is first made to ascertain that the changes will be within the
unit’s operating range.
Leakage inspection and registration
For information on the operator’s responsibility with regards to leakage inspec-
tion and registration, see "1.7 Handling of refrigerant" page 5.
Visual check
Check:
1. The fins on the condenser/evaporator to detect mechanical deformations
2. The drip tray and drain with water trap (clean if necessary)
3. That the water trap (without non-return valve) is filled with water.
Cleaning
If the fins are fouled, they should be vacuumed from the inlet side. Alternatively,
you can blow them clean with compressed air from the outlet side. If they are
severely fouled, you can clean them with warm water mixed with dishwashing
detergent that will not corrode aluminium.

Check function
Check that the reversible heat pump in the air handing unit is operating as it
should by temporarily lowering/increasing the temperature setting (setpoint).
