Climate Master Heat Pump GRV012AGC10CLTS

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.

CAUTION: Fin edges are sharp. Handle with care.

Check the air coil for dirt. If dirty, proceed to next step.

Brush or vacuum clean the air coil. Be careful not to damage the aluminum fins.

Warning: Only trained personnel should perform this check

If dry operation is suspected, report to the maintenance team

Enter the amp draw from the serial plate data

Enter the actual amp draw from the motor

If the actual amp draw is more than 10% greater than the serial plate data, report to the maintenance team

Ensure that electrical power to the unit is disconnected.

Install the system with the supply hose connected directly to the return riser valve. Use a single length of flexible hose.

Open all air vents. Fill the system with water. DO NOT allow system to overflow. Bleed all air from the system. Pressurize and check the system for leaks and repair as appropriate.

Verify that all strainers are in place. Start the pumps, and systematically check each vent to ensure that all air is bled from the system.

Verify that make-up water is available. Adjust makeup water as required to replace the air which was bled from the system. Check and adjust the water/air level in the expansion tank.

Set the boiler to raise the loop temperature to approximately 85°F [29°C]. Open a drain at the lowest point in the system. Adjust the make-up water replacement rate to equal the rate of bleed.

Refill the system and add trisodium phosphate in a proportion of approximately one pound per 150 gallons (.8 kg per 1000 l ) of water. Reset the boiler to raise the loop temperature to 100°F [38°C]. Circulate the solution for a minimum of 8 to 24 hours. At the end of this period, shut off the circulating pump and drain the solution.

When the cleaning process is complete, remove the short-circuited hoses. Reconnect the hoses to the proper supply, and return the connections to each of the units. Refill the system and bleed off all air.

Test the system pH with litmus paper. The system water should be in the range of pH 6.0 - 8.5. Add chemicals, as appropriate to maintain neutral pH levels

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.

Is the cabinet set up from the floor a few inches [7 - 8 cm]?
