Although a high-performance Taco 4900 Separator is installed in the
HydroBox (vent shipped in the closed position), it is recommended that
additional air vents be placed at the high points of the system piping,
including between the HydroBox and the Heat Pump and between the
HydroBox and domestic hot water tank to help in purging air out of the
system piping.

To protect the paintwork, avoid leaning anything against putting objects on
top of either unit. The units can be cleaned and polished with conventional
agents, e.g. car polish.
The evaporator, fan and condensate drain should be cleaned of
contamination (leaves, twigs, etc.) before each new heating season.
The HydroBox doesn't require routine maintenance. However, annual
visual inspection of the piping, vents, and drip pan's drain connection (see
Fig 3.2 #10) to make sure it has not become clogged is recommended.
If glycol is being used, follow the glycol manufacturer's recommendations for
maintenance and testing, which is usually yearly, to maintain the correct pH
of the system fluid. Failure to do so can result in performance degradation
and/or system equipment and piping failures.
To prevent the evaporator and the condensate tray from being damaged, do
not use hard or sharp objects when cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the air
intake and air outlet areas in individual cases. If this happens, the ice must
be removed from the vicinity of the intake and air outlet area to ensure that
the minimum air flow is maintained.
To ensure proper drainage from the condensate tray, it must be regularly
inspected and cleaned, if necessary.
To prevent faults due to sediment in the heat exchangers, care must be
taken to ensure that no impurities can enter either the heat source system
or the heating system. In the event that operating malfunctions due to
contamination occur nevertheless, the system should be cleaned as
described below.
Note:
Never use cleaning agents containing sand, soda, acid or chloride,
as these can damage the surfaces.
Note:
Personal protective equipment (protective goggles, safety shoes
and gloves where necessary) must be used when working on the device.
Components with plastic parts must be protected from impact (e.g. from
tools) to prevent damage to these components.
Caution:
Before opening the device, ensure that all circuits are
disconnected from the power supply. Multiple disconnects might
be present.
Caution:
Work on the system must only be performed by
authorized and qualified after-sales service technicians.
Caution:
Before opening the device, ensure that all circuits are
disconnected from the power supply. Multiple disconnects may
be present.
This heat pump is a quality product and is designed for trouble-free
operation. In the event that a fault should occur, it will be indicated on the
user interface display.
If you cannot correct the fault yourself, please contact your after-sales
service technician.
Before removing the heat pump, disconnect the machine from the power
source and close all inflow and outflow valves. The heat pump must be
dismantled by trained personnel. All environmentally-relevant requirements
regarding the recovery, recycling and disposal of materials and components
should be observed in accordance with the applicable standards. Particular
attention should be paid to the proper disposal of refrigerants and refrigerant
oils.
