Climate Master Heat Pump GRH019AGC10CLTS

Ensure that electrical power to the unit is disconnected.

Is the supply hose connected directly to the return riser valve?

Is the system filled with water without overflow?

Is all air bled from the system?

Is the system pressurized and checked for leaks?

The air coil must be cleaned to obtain maximum performance.

Check once a year under normal operating conditions and, if dirty, brush or vacuum clean.

Care must be taken not to damage the aluminum fins while cleaning.

Warning: Do not allow water to stay in contact with the cabinet for long periods of time to prevent corrosion of the cabinet sheet metal.

Note: Generally, vertical cabinets are set up from the floor a few inches [7 - 8 cm] to prevent water from entering the cabinet.

Direct ground water applications only

If the system is installed in an area with a known high mineral content (125 P.P.M. or greater) in the water, it is best to establish a periodic maintenance schedule with the owner so the coil can be checked regularly.

Enter the water flow rate. Minimum flow rate for entering water temperatures below 50°F [10°C] is 2.0 gpm per ton [2.2 l/m per kW].

All other water loop applications

Generally water coil maintenance is not needed for closed loop systems. However, if the piping is known to have high dirt or debris content, it is best to establish a periodic maintenance schedule with the owner so the water coil can be checked regularly.

Enter the water flow rate. Flow rates over 3 gpm per ton (3.9 l/m per kW) can produce water (or debris) velocities that can erode the heat exchanger wall and ultimately produce leaks.

Warning: This inspection requires trained personnel with PPE!

Is the potable water hard or not chemically softened?

If the water is hard, the desuperheater will tend to scale even quicker than the water coil and may need more frequent inspections.
